Docker

We´re huge devop fans - and devops love Docker. Docker is the most popular application container platform in the world. For your convenience, we build Docker images of every Enonic XP release.

_images/docker.png

Install Docker

Running Enonic XP with Docker actually requires access to a Docker container - now, that’s a surprise!

Note

Docker version 1.8.1 or newer is required to complete this guide

If you don’t already have a Docker up and running, we recommend reading the brilliant documentation on how to get started with Docker:

Start Server

Launch Enonic XP on Docker

With Docker up and running, installing Enonic XP is as smooth as baby skin. Execute the commands below in your terminal/shell to get going.

  • Create a storage container for configuration files, applications and data (XP_HOME)
docker run -it --name xp-home enonic/xp-home
  • Install and start Enonic XP, mounting the xp-home volume
docker run -d -p 8080:8080 --volumes-from xp-home --name xp-app enonic/xp-app

This will download the latest stable Enonic XP image, start it, and map it to port 8080 on your docker-host. You can optionally add :<versionnumber> at the end of the command to launch a specific version of Enonic XP - i.e.

docker run -d -p 8080:8080 --volumes-from xp-home --name xp-app enonic/xp-app:6.12.3

My First App

This guide will lead you through the required steps to build the “Hello World” app for Enonic XP.

This three-part tutorial will cover the basics of creating a website application for Enonic XP. You will learn how to initialize new application projects and deploy them. We will create a simple website that displays a list of countries and cities with a Google map of each city. Upon completion, you will be familiar with content types, page and part components, page templates, regions, and the Content Studio app. You won’t be writing any code - just copy/paste from the examples.

The screen-shots below show the final product of this tutorial.

Note

To complete this tutorial, you will need a local running installation (see For Developers) of Enonic XP and a text editor of your choice. All terminal actions assume you’re using OSX or Linux.

Part 1: Project set up

In this first section, you will learn how to initialize a new project with the CLI toolbox that comes with Enonic XP. Then you will build and deploy the app with Gradle. Next you will create a couple of files for your first page component. Finally, you’ll create a site with your app in the Content Studio.

Initialize project

Enonic XP includes the Toolbox CLI which can perform several useful operations. The init-project operation will clone an existing project from a repository source, such as GitHub. The starter-vanilla project will initialize a new application with the standard structures required (see Projects).

  1. Create a new folder at a suitable location on your filesystem for the application project files. e.g. /Users/<username>/projects/myapp This will be the project root.
  2. Change directory in the terminal to this project root. cd /Users/<username>/projects/myapp
  3. Run the following command, replacing [$XP_INSTALL] with the path to your unzipped XP installation:
[$XP_INSTALL]/toolbox/toolbox.sh init-project -n com.company.myapp -r starter-vanilla -c v1.1.0

For example, if your XP installation is at /Users/enonic/installs/enonic-xp-6.9.0 then you would enter:

/Users/enonic/installs/enonic-xp-6.9.0/toolbox/toolbox.sh init-project -n com.company.myapp -r starter-vanilla -c v1.1.0

Tip

Only basic characters (a-z, 0-9 and .) may be used for application names, and the name must be globally unique. We recommend following standard Java package naming conventions such as com.mycompany.myapp.

Your project folder will now be filled with the standard folder structure for developing an app.

Build and Deploy

Now that the basic project structure is set up, we should test that it builds and deploys successfully. But before deploying the app, the $XP_HOME environment variable must be set to the path of the home folder of the XP installation.

  1. Run the following command in the terminal, replacing [$XP_INSTALL] with your installation location (no brackets):

Linux and OSX:

export XP_HOME=[$XP_INSTALL]/home

For example, if your XP installation is at /Users/enonic/installs/enonic-xp-6.9.0 then you would enter:

export XP_HOME=/Users/enonic/installs/enonic-xp-6.9.0/home

Windows:

set XP_HOME=[$XP_INSTALL]/home
  1. Execute the following command (from the project root directory):

Linux and OSX:

./gradlew deploy

Windows:

gradlew deploy

The included Gradle wrapper will build the app and then attempt to deploy it to your installation.

The deployment step simply moves the result of the build (the application JAR file) into the $XP_HOME/deploy directory. From there, Enonic XP will detect, install and start the application automatically.

You will need to access the Administrative console to check that the app has installed and started. Enonic XP must be running to proceed.

3. Log in to the Administrative console (http://localhost:8080) with the Administrative user credentials. (The default credentials are userid: su and password: password).

  1. Navigate to the Applications Tool. The application you just deployed should be listed here.
  2. Click the app called “Myapp” to see information about it and confirm that it has started.
_images/myapp-apps.jpg

Note

You can change the display name of the application by editing the gradle.properties file.

Create the Hello World Site

Our next goal is to set up a “Hello World” site in Content Studio, but first we must add some initial configuration to our project.

Site descriptor

An application can serve many purposes and building sites is just one of them. The site.xml file is the descriptor that will let Enonic XP know that this app can be added to a site. Response filters and controller mappings can be set up in the site descriptor as well as application configurations (see Site Descriptors).

A basic site.xml file was automatically created by the init-project script and we don’t need to make any changes for now. Later in this tutorial we will edit site.xml to add a site-wide configuration.

[project-root]/src/main/resources/site/site.xml
Application description and icon

The application.xml file at [project-root]/src/main/resources/application.xml can be edited to provide a suitable description for your app. Go ahead and give your app a custom description.

The application.svg file can be replaced with a custom app icon. The description and icon will be visible in the admin tools.

Note

Most of the files we will be working with are below the “site” directory in the project folder - src/main/resources/site. All file paths from now on will begin with “site/”.

Page Component

Page components are the most basic building blocks of websites in Enonic XP (see Page). They require a JavaScript controller and optionally an XML descriptor and an HTML view. This first example does not need a descriptor file.

A page controller (see Page) is a JavaScript file that handles requests such as GET and POST. Controllers usually pass data in the form of a JavaScript object to be dynamically rendered in an HTML view. No data is passed in the example below, but the view file is specified and rendered as static HTML.

  1. Create a folder called hello inside the site/pages directory.
  2. Create the page controller and page view files specified below inside the hello folder:
Hello page controller - site/pages/hello/hello.js
var thymeleaf = require('/lib/xp/thymeleaf'); // Import the thymeleaf library

// Handle the GET request
exports.get = function(req) {

    // Specify the view file to use
    var view = resolve('hello.html');

    // Render HTML from the view file
    var body = thymeleaf.render(view, {});

    // Return the response object
    return {
        body: body
    }
};

The view below is a simple HTML file. This file will be updated later to handle dynamic content.

Hello page view - site/pages/hello/hello.html
<!DOCTYPE html>
<html>
    <head>
        <title>Hello world</title>
    </head>
    <body data-portal-component-type="page">
        <h1>Hello world</h1>
    </body>
</html>
  1. Once these files are in place, redeploy the app from the terminal with ./gradlew deploy.

Tip

Each page controller must reside in its own folder under the site/pages directory. The name of the controller JavaScript file must be the same as the directory that contains it. The HTML view file can reside anywhere in the project and have any valid file name. This allows view files to be shared between components.

Create Site

Now that the files are in place, we can create the site in a browser using the Content Studio admin tool. Switch between different tools by clicking the menu icon menuicon (top right) to open the Launcher panel.

  1. In your browser, navigate to the Content Studio tool. (Use the menu icon at the top right)
  2. Click “New” and select “Site” from the list of content types (Opens a tab for editing the new site).
  3. Fill in the form with Display Name: “Hello World”.
  4. Select your “MyApp” application in the “Applications” dropdown.
  5. If you don’t see a blue area on the right of the page then click this button monitoricon in the toolbar to open the Page Editor.
  6. Use the dropdown in the Page Editor (blue area) to select the “hello” page.
  7. Click the “Save draft” button in the toolbar (top-left).
  8. Now close the “Hello World” site editor tab to see the content pane.

When you click on the “Hello World” site content, the preview should look something like this:

_images/hello-world-site1.jpg

This concludes part one of the tutorial. Let’s review: You’ve learned how to initialize a new project with the CLI toolbox init-project. Then you set the $XP_HOME environment variable and deployed the app with gradle. Next, you created a page component with a JavaScript controller and an HTML view file. Finally, you created a site in the Content Studio and added the app and page component to the site. This might seem like a lot of work just to make a static page; but we have laid a solid foundation in preparation for dynamically displaying structured content in reusable components which you will learn about in the next section.

Part 2: Content types and parts

Welcome to part two. Now it is time to introduce content types for structured data and how to display the data with part components. You will also learn how to build pages and page templates with components and regions.

Add some Countries

In order to make our “World” slightly more interesting, we will add some countries as structured data.

The structure of data (such as countries) are defined in XML files and are referred to as Content Types. The content type defines the form (and underlying schema) of items you manage.

  1. Create a folder named “country” inside the “content-types” folder of your project.
  2. Create an XML file named “country.xml” in the “country” folder and paste in the code below for the Country content type.
Country content type - site/content-types/country/country.xml
<content-type>
  <display-name>Country</display-name>
  <super-type>base:structured</super-type>
  <form>
    <input type="TextArea" name="description">
      <label>Description</label>
      <occurrences minimum="0" maximum="1"/>
    </input>
    <input type="TextLine" name="population">
      <label>Population</label>
      <occurrences minimum="0" maximum="1"/>
    </input>
  </form>
</content-type>

Each content type can have a custom icon that will be visible in the Content Studio interface. Though not required, content icons can be helpful for content editors.

  1. Copy the image below to the the same folder (content-types/country) with the name country.png.
_images/country.png

This content type defines form inputs for description and population. Every content has a built-in field for Display Name. When the app is redeployed, you can create a new content of type “Country” in the Content Studio. The Country content type will produce the form seen below. Each country content that is created with this form will become a page in the site when a page component is added to it with the dropdown in the page editor on the right. More on this later.

_images/country-content-form.jpg

Tip

Each content type must reside in its own folder under the site/content-types directory. The name of the content type XML file and the icon PNG file must be the same as the directory that contains them.

Create the Country Part

We also need a way to display the data from our Country content type. This time, rather than making another page controller, we will create a Part component. Parts are reusable components that can be added to “regions” in pages or layout components - more on this later.

  1. Create a folder called “country” inside the “parts” folder in your project.
  2. Add the part controller and view files below to the “country” folder:
Country part controller - site/parts/country/country.js
var portal = require('/lib/xp/portal'); // Import the portal library
var thymeleaf = require('/lib/xp/thymeleaf'); // Import the Thymeleaf library

// Handle the GET request
exports.get = function(req) {

    // Get the country content as a JSON object
    var content = portal.getContent();

    // Prepare the model object with the needed data from the content
    var model = {
        name: content.displayName,
        description: content.data.description,
        population: content.data.population
    };

    // Specify the view file to use
    var view = resolve('country.html');

    // Return the merged view and model in the response object
    return {
        body: thymeleaf.render(view, model)
    }
};

The part controller file above handles the GET request and passes the country content data to the view file which is shown below.

Country part view - site/parts/country/country.html
<div>
    <h3 data-th-text="${name}"></h3>
    <div data-th-if="${population}" data-th-text="'Population: ' + ${population}"></div>
    <div data-th-if="${description}" data-th-text="${description}"></div>
</div>
The Hello Region Page

Parts start to make sense when placed into a region. Regions are “slots” contained within pages or layouts. Pages and layouts may contain multiple regions, and each region must have a unique name.

Let’s create a new page component with a single region called “Main”. Later we will use the Content Studio to place the “Country” part into this region.

The benefit of a region (see Regions) is that a page component can be re-used across multiple different pages by simply adding different parts to them as needed.

  1. Create a folder called “hello-region” in your project’s site/pages/ folder.
  2. Add the “Hello region” page descriptor, controller and view files:
Page descriptor - site/pages/hello-region/hello-region.xml
<page>
  <display-name>Hello Region</display-name>
  <config/>
  <regions>
    <region name="main"/>
  </regions>
</page>

The XML file above is a Descriptor. Regions and page configurations can be defined here.

Page controller - site/pages/hello-region/hello-region.js
var portal = require('/lib/xp/portal'); // Import the portal library
var thymeleaf = require('/lib/xp/thymeleaf'); // Import the Thymeleaf library

// Handle the GET request
exports.get = function(req) {

    // Get the content that is using the page
    var content = portal.getContent();

    // Extract the main region which contains component parts
    var mainRegion = content.page.regions.main;

    // Prepare the model that will be passed to the view
    var model = {
        mainRegion: mainRegion
    }

    // Specify the view file to use
    var view = resolve('hello-region.html');
    
    // Return the merged view and model in the response object
    return {
        body: thymeleaf.render(view, model)
    }
};

This page controller uses a portal library (see lib-portal in Javascript Libraries) to get the content and extract the “main” region which was defined in the descriptor XML file.

Page view - site/pages/hello-region/hello-region.html
<!DOCTYPE html>
<html>
<head>
    <title>Hello world</title>
</head>
<body>
    <h1>Country</h1>
    <div data-portal-region="main">
        <div data-th-if="${mainRegion}" data-th-each="component : ${mainRegion.components}" data-th-remove="tag">
            <div data-portal-component="${component.path}" data-th-remove="tag"></div>
        </div>
    </div>

The view file above defines the place on the page where the region will render component parts that are dragged and dropped in the Page Editor.

  1. When done - redeploy your app once again!
./gradlew deploy

Tip

You can restart XP in Development mode and then the app won’t have to be redeployed after making changes.

Add your favorite country

Now that the “Country” content type is installed (and we have a part to display them), we can create new countries using the Content Studio interface.

  1. Right-click on the “Hello World” site from the navigation tree and select “New”. The “Create Content” dialogue will open.
  2. Click “Country” from the list of content types.
  3. Fill in the form with the details of your favorite country.

Similar to the site, we must also configure a view for the country

  1. In the toolbar, in the top right corner of the page, click the button with the monitor icon monitoricon to activate the Page Editor (blue background).
_images/country-content-edit.jpg
  1. In the Page Editor, select “Hello Region” from the template selector dropdown. If the dropdown arrow is not visible, double-click inside the option field or start typing “hello world” in it to see the options.

The blue box with “Drop here” is the region that we defined in the project code and it’s where we add components here in the page editor.

  1. Click the cog button cogicon in the toolbar to open the Inspection Panel (far right).
  2. In the Inspection Panel, click the “Insert” tab. This reveals a list of default component types that can be placed into regions.
  3. Click and drag the “Part” particon into the box on the page.
  4. A new dropdown option will appear. Select the “country” part.
  5. Save draft and close the content edit tab.

When you click on the country in the content pane, you should see a preview of the rendered page, something like this:

_images/country-content-rendered.jpg
The Country Page Template

With our current solution, sadly, we would have to create a new page for every country we add. As this is not a very effective way of working with large data sets, we will create a page template that will automatically render all country content.

  1. Select the Templates item templatesicon located below the “Hello World” site in the content pane.
  2. Click “New” and select “Page Template”.
  3. Fill in the form as follows:
  • Display Name: “Country”
  • Supports: “Country” (selected from the list of content types)
  1. If the blue Page Editor panel is not displayed on the right, click the monitoricon button in the toolbar.
  2. Select the “Hello Region” controller with the dropdown in the blue Page Editor panel.
  3. Open the Inspection Panel (activated from the cog button cogicon in the toolbar).
  4. Under the “Insert” tab, drag and drop a “Part” particon into the empty region where it says “Drop here”.
  5. Select the “country” part from the dropdown.
  6. Click “Save draft” in the toolbar and close the tab.

Every “Country” content you create will now use this template by default.

Tip

The “Support” property is the key. A page template will support rendering of the content types specified here.

Try this out by creating a few new countries in your site. Be aware that every content you create will be a child of the content that was selected in the content pane, so make sure you select the “Hello World” site before clicking “New” in the toolbar. Or better yet, get in the habit of right-clicking the desired parent content and selecting “New” from the context menu. This way you will never accidentally create a content in the wrong place.

Tip

From Enonic XP 6.11, The Detail Panel on the far right of the Browse View has a little box showing the rendering mode. Compare your favorite country to other countries that are rendered automatically:

_images/rendering-mode-view.png
Extra task

Make your Favorite Country use the page template too!

You might remember that your favorite country was “hardcoded” - so let’s change it to use templates as well.

  1. In the Content pane, double click the country content to edit it.
  2. Open the Inspection Panel cogicon and select the “Inspect” tab if it’s not already selected.
  3. You should see a label for “Page Template” with “Custom” selected and a label for “Page controller” with “Hello Region” selected. If you see a label for “Part” instead then click on the page above the country name to select the page. Then click the “Inspect” tab. (See image below)
  4. Now select “Automatic” from under the “Page Template” label in the “Inspect” tab.
  5. Save draft and close the tab.
_images/page-template-automatic.jpg

You can select another Page template at any time, or even customize the presentation of a single content.

The Country List Part

Each country content can now be viewed on a page. But the site home page is still a bit empty. This section will have you alter the “hello” page controller and view files to list all of the country contents.

  1. Edit the “hello” page controller site/pages/hello/hello.js and replace the file’s contents with the code below:
var thymeleaf = require('/lib/xp/thymeleaf'); // Import the thymeleaf library
var contentLib = require('/lib/xp/content'); // Import the content service library
var portal = require('/lib/xp/portal'); // Import the portal library

// Handle the GET request
exports.get = function(req) {
    var model = {};

    var site = portal.getSite();

    // Get all the country contents (in the current site)
    var result = contentLib.query({
        start: 0,
        count: 100,
        contentTypes: [
            app.name + ':country'
        ],
        "query": "_path LIKE '/content" + site._path + "/*'"
    });

    var hits = result.hits;
    var countries = [];

    // Loop through the contents and extract the needed data
    for(var i = 0; i < hits.length; i++) {

        var country = {};
        country.name = hits[i].displayName;
        country.contentUrl = portal.pageUrl({
            id: hits[i]._id
        });
        countries.push(country);
    }

    // Add the country data to the model
    model.countries = countries;

    // Specify the view file to use
    var view = resolve('hello.html');

    // Return the merged view and model in the response object
    return {
        body: thymeleaf.render(view, model)
    }
};
  1. Now edit the “hello” view file site/pages/hello/hello.html and replace its contents with the code below:
<!DOCTYPE html>
<html>
<head>
    <title>Hello world</title>
</head>
<body data-portal-component-type="page">
    <h1>Hello world</h1>
    <h2>Countries</h2>
    <ul>
        <li data-th-each="country : ${countries}">
            <strong>
                <a data-th-href="${country.contentUrl}" data-th-text="${country.name}"></a>
            </strong>
        </li>
    </ul>
</body>
</html>
  1. If you didn’t start XP in Development mode then redeploy the app from the command line with ./gradlew deploy.

Each country that you created is now listed on the home page and the names are also links to the individual content pages.

This concludes part 2 of the tutorial. Let’s review what you’ve learned. First you created a content type by defining the data structure for countries in the country.xml file. Then you created a custom part component to display the country data. Next you created a new page component with a region. In the Content Studio, you created some “country” contents and added the page and put the country part in the region. Then you made a page template to automatically render a page for all the country content. Finally, you modified the first page component to show a list of the countries on the home page.

In the next section you will add cities to the site and learn how to make configurable parts.

Part 3: Configurable components

Welcome to part three. Here we will create a new content type for cities and a configurable component to display them. You will also learn how to make app configurations and you will get more practice with the Content Studio. Part three will conclude with content publishing and some advice and best practices.

Hello Geo World

The home page of the site now shows a list of the countries we have added. To make this even more exciting, we will add a City content type with geo-location and a City list part with configuration capabilities.

City content

The next steps will create a content type for adding cities with location coordinates.

  1. Create a folder named city inside the project’s site/content-types folder.
  2. Add the content type file below to your project. Because the contet type’s folder is named “city” the file must be named “city.xml”.
City content type - site/content-types/city/city.xml
<content-type>
  <display-name>City</display-name>
  <super-type>base:structured</super-type>
  <form>
    <input type="GeoPoint" name="location">
      <label>Location</label>
      <occurrences minimum="1" maximum="1"/>
    </input>
    <input type="TextLine" name="population">
      <label>Population</label>
      <occurrences minimum="0" maximum="1"/>
    </input>
  </form>
</content-type>

The file above defines a content type for cities with a required field for the location in latitude and longitude.

  1. Copy the image below and save it in the same folder with the City content type. Name it “city.png”.
_images/city.png
City list part

We need a part component to display the city data. It will list the cities and show a Google map of each location.

  1. Create a folder named city-list inside the project’s site/parts folder.
  2. Add the part descriptor file. It must be named city-list.xml.
City list part descriptor - site/parts/city-list/city-list.xml
<part>
  <display-name>City list</display-name>
  <config>
    <input type="ComboBox" name="mapType">
      <label>Map type</label>
      <occurrences minimum="0" maximum="1"/>
      <config>
        <option value="ROADMAP">ROADMAP</option>
        <option value="SATELLITE">SATELLITE</option>
        <option value="HYBRID">HYBRID</option>
        <option value="TERRAIN">TERRAIN</option>
      </config>
    </input>
    <input type="TextLine" name="zoom">
      <label>Zoom level 1-15</label>
      <default>10</default>
      <config>
        <regexp>\b[1-9][0-5]?\b</regexp>
      </config>
      <occurrences minimum="0" maximum="1"/>
    </input>
  </config>
</part>

The part descriptor above has a configuration similar to those found in content types.

  1. Add the part controller file. It must be named city-list.js.
City list part controller - site/parts/city-list/city-list.js
var contentLib = require('/lib/xp/content'); // Import the content library functions
var portal = require('/lib/xp/portal'); // Import the portal functions
var thymeleaf = require('/lib/xp/thymeleaf'); // Import the Thymeleaf rendering function

// Handle the GET request
exports.get = function (req) {

    // Get the part configuration for the map
    var config = portal.getComponent().config;
    var zoom = parseInt(config.zoom) || 10;
    var mapType = config.mapType || 'ROADMAP';

    // Get the site configuration for the app
    var siteConfig = portal.getSiteConfig();
    var googleApiKey = siteConfig.googleApiKey;

    // String that will be inserted to the head of the document
    var googleMaps = '<script src="http://maps.googleapis.com/maps/api/js?key=' + googleApiKey + '"></script>';

    var countryPath = portal.getContent()._path;

    // Get all the country's cities
    var result = contentLib.query({
        start: 0,
        count: 100,
        contentTypes: [
            app.name + ':city'
        ],
        query: "_path LIKE '/content" + countryPath + "/*'",
        sort: "modifiedTime DESC"
    });

    var hits = result.hits;

    var cities = [];

    if (hits.length > 0) {
        googleMaps += '<script>function initialize() {';

        // Loop through the contents and extract the needed data
        for (var i = 0; i < hits.length; i++) {

            var city = {};
            city.name = hits[i].displayName;
            city.location = hits[i].data.location;
            city.population = hits[i].data.population ? 'Population: ' + hits[i].data.population : null;

            cities.push(city);

            if (city.location) {
                city.mapId = 'googleMap' + i;

                googleMaps += 'var center' + i + ' = new google.maps.LatLng(' + city.location + '); ';

                googleMaps += 'var mapProp = {center:center' + i + ', zoom:' + zoom +
                              ', mapTypeId:google.maps.MapTypeId.' + mapType + ', scrollwheel: false };' +
                              'var map' + i + ' = new google.maps.Map(document.getElementById("googleMap' + i + '"),mapProp); ' +
                              'var marker = new google.maps.Marker({ position:center' + i + '}); marker.setMap(map' + i + ');';
            }

        }

        googleMaps += '} google.maps.event.addDomListener(window, "load", initialize);</script>';
    }

    // Prepare the model object that will be passed to the view file
    var model = {
        cities: cities
    };

    // Specify the view file to use
    var view = resolve('city-list.html');

    // Return the response object
    return {
        body: thymeleaf.render(view, model),
        // Put the maps' javascript into the head of the document
        pageContributions: {
            headEnd: googleMaps
        }
    }
};

There are a few things to note in this controller file. It gets the part configuration for zoom and map type which were defined in the part descriptor. It also gets the site configuration for the Google Maps API key which we will define later in the site.xml file. Page Contributions are used to put the Google Maps JavaScript into the head of the document.

  1. Add the part view file. It must be named city-list.html to match the “resolve” function in the controller.
City list part view - site/parts/city-list/city-list.html
<div class="cities" style="min-height:100px;">
    <h3>Cities</h3>
    <div class="city" data-th-each="city : ${cities}">
        <h3 data-th-text="${city.name}"></h3>
        <div data-th-if="${city.population}" data-th-text="${city.population}"></div>
        <div data-th-id="${city.mapId}" data-if="${city.mapId}" style="width:100%;height:300px;"></div>
        <br/><br/>
    </div>
</div>

There is just one more file to edit and then all the code for this project will be complete.

App configuration

Google Maps won’t work without an API key. We need somewhere to enter the key so that it can be accessed by any component that needs it. The perfect place to define a site-wide configuration is in the site descriptor.

  1. Replace the contents of the site.xml file at site/site.xml with the code below.
Site descriptor - site/site.xml
<site>
  <config>
    <input type="TextLine" name="googleApiKey">
      <label>Google API key</label>
      <help-text>Get your Google maps Javascript API key at: https://developers.google.com/maps/documentation/javascript/get-api-key</help-text>
      <occurrences minimum="1" maximum="1"/>
    </input>
  </config>
</site>

The inputs defined in the site descriptor will appear in a form when editing the site content in the Content Studio.

  1. If you didn’t start XP in Development mode then build and deploy your project one final time with ./gradlew deploy.

All of the project’s files are now complete. The rest of the steps will be performed in the Content Studio interface.

  1. Edit the site content. You will notice that the “Myapp” application is now red due to a missing required configuration.
  2. Click the pencil icon to edit the Myapp configuration and enter your Google API key. You can get a Google API key from the Google developers site if you don’t already have one.
_images/app-config.jpg
Create Cities

Now let’s make use of the new city content type and part component. First we need to add the “City list” part to the “Country” page template.

  1. Edit the “Country” page template. Find it in the content pane below the templates templatesicon
  2. Open the Inspect Panel by clicking the cog button cogicon in the toolbar.
  3. Under the Insert tab, click and drag a Part particon to the page region below the “country” part. (This may be a bit tricky because the “country” part is small.) You could also right-click on the word “Country” and then use the context menu to insert the part.
  4. Select the “City list” part from the dropdown in the box.
  5. Save and close the tab.

Now we need to create a few City contents under each country. (Sample data is available in the table below.)

  1. From the content pane, select a country content that you created earlier. It is important that each city content is created under its country.
  2. Right-click the country content and select “New”. The “Create content” dialogue will open.
  3. Now select “City” from the list of content types.
  4. Fill in the city name and location; the population is optional. The location format must be comma separated latitude and longitude with decimals.
  5. Save draft.
  6. Create several more city contents below each country content by repeating the previous steps. Sample data is provided in the table below.
Country City Lat,Long Population
USA San Francisco 37.7833,-122.4167 837,442
Las Vegas 36.1215,-115.1739 603,488
Washington D.C. 38.9047,-77.0164 658,893
Norway Oslo 59.9100,10.7500 618,683
Bergen 60.3894,5.3300 265,857
Trondheim 63.4297,10.3933 178,021
Colombia Bogota 4.5981,-74.0758 7,000,000
Medellin 6.2308,-75.5906 2,440,000
Barranquilla 10.9639,-74.7964 1,885,500

Each country page will now have a list of the cities you created with a Google map of the location. It should look something like this:

_images/city-list.png
Configure City List

The City list part descriptor (site/parts/city-list/city-list.xml) has configuration inputs for the map type and zoom level. You can set the default values for these inputs by editing the City list part in the Country page template.

  1. Open the Country page template for editing.
  2. Open the Inspection Panel by clicking the cog button cogicon in the toolbar.
  3. Click on the City list part in the Page Editor panel.
  4. Under the “Inspect” tab of the Inspection Panel, set the Map type to “HYBRID” and Zoom level to 12.
  5. Save draft and close the edit tab.

Now all of the countries will show the city maps with the new settings. You can override these defaults for any individual country by editing the Country content and changing its City list part configuration.

_images/city-list-config.jpg
Go Online

Now that your “Hello World” is complete, it’s time to publish.

  1. Select the “Hello World” site in the content pane
  2. Right-click and select “Publish” from the context menu, or click the “Publish” button in the toolbar
  3. The Publishing Wizard will appear. You may click the childrenicon icon to see all child nodes that are published together.
  4. Verify that all your items are listed - click “Publish”!

When publishing content, all the selected items and changes are “cloned” from draft to the master branch (Repository).

You will always see the draft version of content in the preview window and the Page Editor of the Content Studio. If you have placed your site on root level, you can also see your live site at this url: http://localhost:8080/portal/master/hello-world.

Well done - you just created your first App for Enonic XP - The Enonic team congratulates you - we look forward to seeing all the brilliant things you will make.

We are always looking for feedback.

Now take a look at Some Pro Tips.

Some Pro Tips
Adding libraries to your project

Why re-invent the wheel for each app you make? Reusable code can be created in libraries and added to any XP project. Some essential tools can be found in the Util lib, Menu lib, RECAPTCHA and Landing page libraries.

Adding apps to your site

A website can be created from a single app. But a site’s functionality can be extended by adding other pre-made apps. SEO Meta Fields, Disqus comments and Google Analytics are just a few of the many apps that can instantly add features to your site. See what’s available at the Enonic Marketplace.

Handling Multiple projects

A best practice for working on multiple projects would involve keeping a separate XP_HOME folder for each project. The folder structure for such a setup would look something like this:

/Users/<name>/development
/Users/<name>/development/software/<xp-install-version>
/Users/<name>/development/xp-homes/<project-name>/home
/Users/<name>/development/projects/<project-name>/<project-source-files>

An actual implementation with projects called my-first-app and company-site would look like this:

/Users/mla/development/software/enonic-xp-6.8.1
/Users/mla/development/software/enonic-xp-6.9.0
/Users/mla/development/xp-homes/my-first-app/home
/Users/mla/development/xp-homes/company-site/home
/Users/mla/development/projects/my-first-app/...
/Users/mla/development/projects/company-site/...

This allows you to have one Enonic XP installation for each version and as many different XP_HOME folders as you need for your projects. When switching from one project to another, you only have to change the XP_HOME environment variable and then restart the installation of the Enonic XP version that the project was created for.

Check this Enonic Labs article for a more in-depth process. It also includes some bash scripting that will help with setting and changing $XP_HOME and starting and stopping XP.

Logging JSON objects

While developing an app, it can be helpful to see the structure of objects returned by library functions. The best way to do this is to set up a utilities JavaScript file in the project lib folder. Add the following function to the utilities file:

site/lib/utilities.js
exports.log = function (data) {
  log.info('Utilities log %s', JSON.stringify(data, null, 4));
};

Call the log function in any controller like the example below and then check the log after refreshing the page.

var util = require('utilities');

var content = portal.getContent();
util.log(content);

This logging function and many other useful functions are included in the Util library.

Continuous build with Dev Mode or Gradle

It can be quite time consuming to frequently use the terminal to redeploy an app during development. Starting Enonic XP in dev-mode will make most changes to your app code visible immediately on localhost. See the Development mode page for more information about its capabilities and limitations.

Another option is to use ./gradlew -t deploy in the terminal from the project root. This will automatically build and redeploy your app every time changes to a file are detected. This method is slower than dev-mode, but it handles some situations that dev-mode doesn’t. Gradle 2.7 or newer is required.

Both dev-mode and Gradle continuous-mode require the $XP_HOME environment variable to be set in the terminal window.

Next Steps

Build a Custom Selector

This guide will lead you through the required steps to build an input of type Custom Selector.

Create a content type

  • Create a folder called “my-custom-selector” inside the “site/content-types” folder of your project.
  • In that folder create a configuration schema for the “my-custom-selector” content type.
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<content-type>
  <display-name>Custom Selector</display-name>
  <super-type>base:structured</super-type>
  <form>
    <input name="my-custom-selector" type="CustomSelector">
      <label>My Custom Selector</label>
      <occurrences minimum="0" maximum="0"/>
      <config>
        <service>my-custom-selector-service</service>
      </config>
    </input>
  </form>
</content-type>

Create a service (or refer to a service in another app)

  • Create a folder called “my-custom-selector-service” (folder name must match the one specified in the config schema) inside the “resources/services” folder of your project.
  • In that folder create a javascript service file called “my-custom-selector-service.js” (again, the name must match the config schema).
  • Create GET handler method in this service file and make sure it returns JSON in the proper format.

Tip

You can also refer to service file in another application (for example, com.myapplication.app:myservice) instead of adding one to your application.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<content-type>
  <display-name>Custom Selector</display-name>
  <super-type>base:structured</super-type>
  <form>
    <input name="my-custom-selector" type="CustomSelector">
      <label>My Custom Selector</label>
      <occurrences minimum="0" maximum="0"/>
      <config>
        <service>com.myapplication.app:my-custom-selector-service</service>
      </config>
    </input>
  </form>
</content-type>

Response format

Format of JSON response from the service:

id
Unique Id of the option
displayName
Option title
description (optional)
Detailed description
iconUrl (optional)
Path to the thumbnail image file
icon (optional)
Inline image content (for example, SVG)

Example of a simple service file

Below is a simple service file that returns two items in the result set, one with external thumbnail image, and another one with inline SVG markup:

var portalLib = require('/lib/xp/portal');

exports.get = handleGet;

function handleGet(req) {

    var params = parseparams(req.params);

    var body = createresults(getItems(), params);

    return {
        contentType: 'application/json',
        body: body
    }
}

function getItems() {
    return [{
        id: 1,
        displayName: "Option number 1",
        description: "External SVG file is used as icon",
        iconUrl: portalLib.assetUrl({path: 'images/number_1.svg'}),
        icon: null
    }, {

Developer Guide

We <3 Developers!

We’re thrilled to see you here - If you’re a first timer to Enonic XP, we recommend starting on My First App and the Tutorials section - or if you’re more familiar with XP, how about drilling into the Storage chapter. If you’re actually looking for APIs - you’ll find them over here API and Reference Guide.

_images/ready-set-code.jpg

Applications

Like anything that calls itself an operating system - Enonic XP has Applications. The applications can be installed and run on a single server, or an entire cluster.

It is important to note that applications are not limited to being “Web Applications” - they can be running server jobs, provide internal API’s to other applications, offer HTTP services, include custom Admin Tools, extend other tools or applications, or be used to build sites.

Applications may even carry data, for instance, to initialize a repository or populate a new site.

Life Cycle

Applications have the following life-cycle:

  • installed
  • started
  • stopped
  • uninstalled

When installing applications in an XP cluster - the application is uploaded and stored in the system repository - and then started on all nodes. If an application contains an initialization script, this script will only be executed on the master node - running only once.

Composition

An application file is typically a JAR (.jar). This is short for Java Archive. Enonic XP is built on top of Java and the powerful OSGi framework, so developers with special requirements may utilize capabilities such as exposing and consuming services from other applications. However, since Enonic XP is designed to run Serverside JavaScript, most Projects will be completely free of Java.

To speed up development and enable a high degree of re-use, applications can be composed of Libraries in addition to your own code. Libraries can be built almost like you create applications. Libraries (and applications) are shared through Maven repositories. An example is https://repo.enonic.com. Anyone may configure and run their own repository - for internal as well as external use.

For your amusement, we can also tell you that Enonic XP itself is composed from more than 50 different applications - making the platform extremely modular.

Other Resources

To learn more about applications and how they are built - continue reading the Developer Guide, but pay special attention to the following chapters:

Libraries

Enonic XP provides the concept of libraries in order to speed up development and re-use of functionality and code. Technically, libraries are very similar to Applications, but the main difference is that a library cannot be installed and started by itself.

So, a library may consist of all the same objects you find in applications - such as Assets, Content Types and HTTP Controllers - things you may need in an application.

Finding Libraries

A number of standard and 3rd party libraries are available with the core XP release, check out: Javascript Libraries. You will also find a wide range of libraries on the Enonic Market - https://market.enonic.com/libraries

Adding libraries

Libraries are added to your project by simply referring to them in your build script. Read more about this on our Projects documentation.

Best practice

If you wonder when/how you should create a library, here are some guidelines

  • Strong cohesion: Keep the components in a library together only if they are strongly related. Split them up in multiple libs if they are not.
  • Weak coupling: A library should avoid having dependencies. In practice, this will not always be possible, but apart from the XP APIs, other dependencies should raise an alarm, and only be included after careful analysis showing there is no other way.
  • Use names that are self-explanatory and follow the java naming conventions - for example com.company.lib.mylib.

Projects

This section provides an overview of how to setup, build and deploy new projects for applications and libraries.

Project Initialization

The fastest way to get started with any XP project is to use a starter project. The starter-vanilla project on GitHub - https://github.com/enonic/starter-vanilla is often used.

To get going, we recommend using the init-project script that is a part of the Enonic XP installation.

In the terminal, move to the XP installation’s toolbox folder. Copy/paste the command below and specify an empty folder for -d and an appropriate app name for -n. Then execute the command to get your very own project initialized.

toolbox.sh init-project -d <projectFolder> -n com.mycompany.myApp -r enonic/starter-vanilla

The init-project command simply clones the entire Git project (to the local folder that was specified with -d), then removes the Git references. It also updates your build script files by adding the specified app name (-n) to the project.

Once this is done, you must clean up and adapt the code to your own requirements.

You may, in principle, apply this command to any standard XP application or library project!

Project structure

To build applications with Enonic XP, you will typically setup a project. The fastest way to do this is using the init-project feature included in the Enonic XP toolbox utility.

The project structure is similar to Maven projects for those who are familiar with that.

Below is a sample project folder structure - all items that end with a slash are folders

my-first-app/
  build.gradle
  src/
    main/
      java/
      resources/
        admin/
          widgets/
          tools/
        application.svg
        application.xml
        assets/
        lib/
        main.js
        services/
        site/
          content-types/
          error/
          filters/
          i18n/
          layouts/
          mixins/
          pages/
          parts/
          site.xml
        tasks
        views/

Every file and folder has a specific function and meaning.

build.gradle
Gradle script for building the application or library. This file describes the actual build process.
src/main/java/
Optional folder where you place any java code that might be included in the project - following traditional Maven style development.
src/main/resources/
This is where all non-java code is placed, and thus where you will typically be working with your XP projects. All folders described below are relative to this folder
admin/tools
This is where you place code for admin tools. Tools are administrative user interfaces (apps) running in their own separate browser tab. Create tools if you need a back-office utility to manage your applications or similar.
admin/widgets
Widgets are essentially user interface components that can be embedded within selected tools. I.e. you can create a widget that extends the Content Studio detail panel.
application.svg
Application icon in SVG format.
application.xml

The XML file contains basic information for the application. Currently a description.

<application>
  <description>Application description goes here</description>
</application>
assets/
Public folder for external css, javascript and static images etc. etc.
lib/
This is the last place the global require JavaScript-function looks, so it is a good place to put default JavaScript files here.
main.js
This file may be thought of as an app initializer. It is executed every time the app is started. (see Main Initializer)
services/
Services are a special type of http controller that will be mounted on a fixed url pattern that looks like this: _/service/<myapp>/<myservice>. You may use services like any other JavaScript controller in the system.
site/site.xml

The site.xml file contains basic information for a site created with the application. Settings for the application can be defined in the config element and the values for these settings can be updated using the Content Studio tool.

<site>
  <config>
    <input type="TextLine" name="company">
      <label>Company</label>
      <occurrences minimum="1" maximum="1"/>
    </input>
    <input type="TextArea" name="description">
      <label>Description</label>
      <occurrences minimum="1" maximum="1"/>
    </input>
  </config>
</site>
site/content-types/
Content schemas are placed here. Used to create structured content (see Content Types).
site/error/
Create custom http error pages by placing an error controller in this directory (see Error Handling).
site/filters/
This is where generic http response filters are placed. Filters can be used for post processing any given request - also across applications added to a site. A common use case is adding script tags to pages - but possibilities are virtually endless.
site/i18n/
This folder will contain application localization files (i18n is short for Internationalization). Files placed in this folder must follow Java’s standard property file format, one file for each language. Here is an example: https://docs.oracle.com/javase/tutorial/i18n/resbundle/propfile.html
site/mixins/
Mixin schema-types are placed here. A mixin can be used to add common fields to multiple content-types or other schemas (see Mixins).
site/pages/
Page controllers are placed here. They will be used to render pages and page templates (see Page).
site/parts/
Part controllers should be placed here. Parts are dynamically configurable components that can be placed on pages (see Part).
site/layouts/
Layout controllers should be placed here. Layouts are similar to parts, but in addition have one or more regions. Regions enable placement of other components inside the layout. (see Layout).
tasks/
Contains tasks to be executed asynchronously (see Tasks).
views/
Views are any kind of files that are used for rendering. The folder is optional, as view files can
be placed anywhere you want, just keep in mind what path to use when resolving them (see Views).

Build script

By default, Enonic uses Gradle as the main build tool. This is a highly flexible Java-based utility that builds on the popular Maven project tools and code repository structures. Enonic provides a Gradle plugin that greatly simplifies the build process. If you used the starter-vanilla project to initialize your project, you will have all the basic tools you need to get going.

Running a build

If you have not installed Gradle, the fastest way to get going is to execute the gradle wrapper script.

Move into your project root folder and execute the following command:

OSX/Linux:

./gradlew build

Windows:

gradlew.bat build

The gradle wrapper will download all necessary files to run gradle and produce the project artifacts. These will typically be placed in the projects build/libs/ folder.

gradle.properties

Your project should contain a gradle.properties file. Set xpVersion to the version of Enonic XP you are working with, and look over the other settings to make sure they are correct.

build.gradle

The build.gradle file defines all the dependencies to other libraries.

There are three standard scopes (keywords) used in the dependency list

  • Compile (default gradle scope, compiles library and adds it to class path - standard for pure Java libraries)
  • Include (XP custom scope that merges the /src/main/resources folder in the library with your project - any code in your project overwrites the library files)
  • Webjar (Extracts the content of the specified Webjar - http://www.webjars.org/ - placing it into the assets folder, using the version number as root folder)
gradle deploy

To have Gradle automatically deploy new applications to your XP installation, you have to specify an environment variable that tells Gradle where to place the artifact (application file).

OSX/Linux:

export XP_HOME=/path/to/xp-installation/home

Windows:

set XP_HOME=c:\path\to\xp-installation\home

With $XP_HOME set, run the following command to build and deploy the file

OSX/Linux:

./gradlew deploy

Windows:

gradlew.bat deploy

Once completed, your XP installation will detect, install and start the files.

Installing an application

There are several ways to install applications

  • Uploading directly from the “Applications” admin tool - this will install and start the application in the entire cluster
  • Use the Toolbox CLI command line utility - this will install and start the application in the entire cluster.
  • And finally, the developer way - copying the application JAR file to the $XP_HOME/deploy folder - this will install and start the application on the local node (typically used by developers)

Once an application is placed in this folder, it will be picked up, installed and started by the local instance. If the application is removed it will be stopped and uninstalled.

OSX/Linux command line to copy the artifact to the deploy folder:

cp build/libs/[artifact].jar $XP_HOME/deploy/.

For your convenience - we have simplified this process by adding a deploy task to your build. Instead of manually copying to the deploy folder, you can simply execute gradle deploy:

./gradlew deploy

For the deploy command to work, you have to set the XP_HOME environment variable (in your shell) to your actual Enonic XP home directory.

Run the following command to set the XP_HOME variable

OSX/Linux:

export XP_HOME=/path/to/xp-installation/home

Windows:

set XP_HOME=c:\path\to\xp-installation\home
Continuous Deploy

To continuously build and deploy your application on changes, you can use Gradle continuous mode. This will watch for changes and run the specified task when something changes. To use this with the deploy task, you can run the following command:

./gradlew -t deploy

This will deploy and reload the application on the server when something changes in your project. The continuous deployment mode is most useful when coding Java, or other changes that require a full compile and re-deploy.

For the instant updates of JavaScript code without re-deploying, check out Development mode.

Sample library

In this example, we will create support for redirection of URLs. For this, we need a content-type, and a simple JavaScript file.

The content-type, let’s just call it url, defines the URLs that the code may redirect to. So in the content-types directory, add a new directory and name it url. Then, in this directory, create the content type:

src/main/resources/site/content-types/url/url.xml
<?xml version="1.0" encoding="UTF-8"?>
<content-type>
  <display-name>URL</display-name>
  <content-display-name-script>$('url')</content-display-name-script>
  <super-type>base:structured</super-type>
  <form>
    <input type="TextLine" name="url">
      <label>URL</label>
      <occurrences minimum="1" maximum="1"/>
    </input>
  </form>
</content-type>

To make it easier to notice when creating a new content in Enonic XP, add this icon, url.png in the same directory:

_images/url.png

Now, we need the JavaScript. Since we are talking about a redirect here, the script must be placed on a page. So, in the pages directory, we add a folder: url-redirects . In this, we need the page descriptor:

src/main/resources/site/pages/url-redirect/url-redirect.xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<page>
    <display-name>URL redirect</display-name>
    <config/>
</page>

Then, we add the code that does the actual redirect:

src/main/resources/site/pages/url-redirect/url-redirect.js
var portal = require('/lib/xp/portal');

// Handle GET request
exports.get = handleGet;

function handleGet() {
    var result = portal.getContent();
    var url = result.data.url;

    var response = {};

    if (url) {
        response.redirect = url;
    }
    else {
        response.body = 'No URL configured.'
    }

    return response;
}

This library can now be included in any app where you might want redirect functionality, or in other libs that can build more advanced functions based on this simple example.

You can start the server in dev-mode to speed up the development process. When using this mode, you only need to deploy your code once - or when certain situations arise (see below).

Start server using dev-mode:

$ $XP_INSTALL/bin/server.sh dev

First time you will need to deploy the code (app, lib, etc.) using the deploy task (see Installing an application):

$ ./gradlew deploy

After that, you do not need to redeploy your application except…

  • when modifying Java code.
  • when deleting a page, part or layout component.
  • when deleting a content-type, mixin or relationship-type.
  • when changing source directories.
  • if you have source-transformation tools (typescript, less, sass).

Warning

Do not use dev-mode in production environments. It takes a little more time to render pages and caches are sometimes disabled.

Schemas

As the low level storage of Enonic XP is entirely schema-less, we have created a high-level schema concept that is used to configure many of the forms you see in the Enonic XP Admin.

Schemas are made up of the following main concepts:

  • A rich set of widgets called Input Types
  • Rich Forms by combining Input Types and layouts
  • Horizontal inheritance across forms through the use of Mixins

Input Types

Input types are specified by XML snippets and used in combinations to build forms. An input type has both a front-end and a back-end. Each input type will return a property with a specific value type.

The following XML configuration is common for all input types:

<input name="name" type="type-name">
  <label>Some label</label>
  <occurrences minimum="0" maximum="1"/>
  <help-text>Use me to provide some extra info for the input</help-text>
  <config/>
</input>
@name (required)
The name attribute is the technical name used in templates and result sets to refer to this value.
@type (required)
The type refers to one of the many input types which are explained below.
label (required)
The label text will become the label for the input field in the editable form of the admin console.
help-text
This optional text will be shown next to the input field and can be used for explanation of the field’s purpose.
occurrences
Detailed definition of how many times this field may be repeated inside one content. Set minimum to zero for fields that are not required, and maximum to zero for fields that have no restriction on the number of values. This element is optional, if omitted the default will be minimum="0" and maximum="1".
config
Optional configuration that is used by some of the input-types. The config consists of elements with optional attributes. Each element/attribute name with dashes is automatically camel-cased (relationship-type -> relationshipType).
default
Optional element that contains a default value for the particular input type. Currently it is only supported by some input types. See below for value formats for each input type. Invalid values for a given input type will be ignored.
AttachmentUploader

This field enables uploading of one or more files that will be stored as attachments to the current node/content. This is different from media content where each media is a separate node that can be linked to.

<input type="AttachmentUploader" name="myname">
  <label>My Label</label>
  <occurrences minimum="0" maximum="0"/>
</input>
common fields
All Input Types have these Common Fields
CheckBox

A checkbox field has a value if it is checked, or no value if it is not checked. Therefore, the only values for occurrences that makes sense is a minimum of zero and a maximum of one, which is default and may be skipped.

<input name="name" type="CheckBox">
  <label>Required</label>
  <occurrences minimum="0" maximum="1"/>
  <default>checked</default>
  <config>
    <alignment>right</alignment>
  </config>
</input>
common fields
All Input Types have these Common Fields
default
This element specifies the default value. Set it to checked to check it, otherwise it will be left unchecked.
config
alignment
This config setting can be used to configure checkbox position in relation to its label. Default alignment is to the left of the label. Supported values are: “left”, “right”, “top”, “bottom”.
ComboBox

A ComboBox needs a list of options.

<input name="name" type="ComboBox">
  <label>Required</label>
  <occurrences minimum="1" maximum="1"/>
  <config>
    <option value="one">Option One</option>
    <option value="two">Option Two</option>
  </config>
  <default>one</default>
</input>
common fields
All Input Types have these Common Fields
option
This element defines the option label. The value attribute defines the actual value to set when this option is selected. Multiple option settings are ordered.
default
This element specifies the default option for the combo box. It should be equal to one of the option values.
ContentSelector

References to other content are specified by this input type. Use the toggle icon to switch between the list mode (default) and the tree mode.

<input name="name" type="ContentSelector">
  <label>Cited In</label>
  <occurrences minimum="0" maximum="0"/>
  <config>
    <relationshipType>system:reference</relationshipType>
    <allowContentType>citation</allowContentType>
    <allowContentType>my.other.app:quote</allowContentType>
    <allowPath>${site}/people/</allowPath>
    <allowPath>./*</allowPath>
    <allowPath>/quotes*</allowPath>
    <treeMode>true</treeMode>
    <showStatus>true</showStatus>
    <hideToggleIcon>true</hideToggleIcon>
  </config>
</input>
common fields
All Input Types have these Common Fields
relationship
This setting defines the name of which relationship-type to use. Default is system:reference.
allowContentType
This is used to limit the content types that may be selected for this input. If you only specify content type name - citation - the current app is automatically presumed. You can add another app’s name - my.other.app - followed by a colon (:) and the content type name :quote to allow content from other apps, like so: my.other.app:quote. Use one setting for each content-type.
allowPath
This is used to limit the path of the content that may be selected for this input. The site on which the content exists, can be wildcarded with ${site} Use one setting for each path expression.
<!--
Only content from the current site (but from any location), e.g
  /mySite/fish.jpg
  /mySite/articles/new-blog-post
  /mySite/someFolder/anotherFolder/rubarb/lettuce
-->
<allowPath>${site}/*</allowPath>

<!--
All children of <site>/people, e.g
  /mySite/people/myContent
  /mySite/people/myGroup/anotherContent
-->
<allowPath>${site}/people/*</allowPath>

<!--
All content in mySite starting with people, including children, e.g
  /mySite/peoples
  /mySite/people/myContent
  /mySite/peoples/myContent
  /mySite/people/myGroup/anotherContent
-->
<allowPath>/mySite/people*</allowPath>

<!-- All children of the current content -->
<allowPath>./*</allowPath>

<!-- All children of the current content's parent -->
<allowPath>../*</allowPath>
treeMode
By default content selector is displaying content in the list mode but you can switch it to default tree-mode (same as in the Content grid) by setting treeMode to true.
_images/content-selector-tree.png
showStatus
You can display current status for each content item inside the content selector by setting showStatus to true.
_images/content-selector-status.png
hideToggleIcon
The toggle mode icon can be hidden by setting hideToggleIcon to true.
_images/content-selector-no-toggle.png
ContentTypeFilter

A field for selecting a content type.

<input name="name" type="ContentTypeFilter">
  <label>Target type</label>
  <occurrences minimum="0" maximum="0"/>
  <config>
    <context>true</context>
  </config>
</input>
common fields
All Input Types have these Common Fields
context
true to list only the content types contained in the applications configured for the current site. Otherwise all the registered content types in the system will be listed. Default is false.
CustomSelector

Selector input type with custom data source. Application developers must create a service that returns results according to the required JSON format, and then specify the service name in the input config. For information on creating a service see the Services section.

Below there are two sample usages of CustomSelector input type:

<input name="my-custom-selector" type="CustomSelector">
  <label>My Custom Selector</label>
  <occurrences minimum="0" maximum="0"/>
  <config>
    <service>my-custom-selector-service</service>
  </config>
</input>

<input name="musicTrack" type="CustomSelector">
  <label>Intro song</label>
  <config>
    <service>spotify-music-selector</service>
    <param value="genre">classic</param>
    <param value="sortBy">length</param>
  </config>
</input>
common fields
All Input Types have these Common Fields
service
The name of a JavaScript service file, located under /resources/services/[serviceName]/[serviceName].js. You can also refer to a service file in another application, for example com.myapplication.app:myservice.
option
Parameter to pass to the service. Option parameters allow customizing a CustomSelector to be used in different contexts. There can be multiple options or none. The options will be included in the HTTP request to the service as name-value query parameters.
Service Request

In addition to the option values, if set on the input type <config>, the service will receive the following query parameters in the HTTP request:

ids
Array of item ids already selected in the CustomSelector. The service is expected to return the items with the specified ids.
start
Index of the first item expected. Used for pagination of the results.
count
Maximum number of items expected. Used for pagination of the results.
query
String with the search text typed by the user in the CustomSelector input field.
Service Response

The service controller must have a GET handler that returns results in JSON format. The JSON object returned must include total and count properties as numbers, and hits containing an array of items. Each item in the hits property must have the following fields:

id
Unique Id of the option
displayName
Option title
description (optional)
Detailed description
iconUrl (optional)
Path to the thumbnail image file
icon (optional)
Inline image content (for example, SVG)

Example of JSON response from a CustomSelector service:

{
  "total": 10,
  "count": 2,
  "hits": [
    {
      "id": "1",
      "displayName": "Option number 1",
      "description": "External SVG file is used as icon",
      "iconUrl": "/some/path/images/number_1.svg"
    },
    {
      "id": "2",
      "displayName": "Option number 2",
      "description": "Inline SVG markup is used as icon",
      "icon": {
        "data": "<svg xmlns=\"http://www.w3.org/2000/svg\"/>",
        "type": "image/svg+xml"
      }
    }
  ]
}

Please check our tutorial on how to Build a Custom Selector.

Date

A simple field for dates with a calendar pop-up box in the admin console. The default format is yyyy-MM-dd.

<input name="name" type="Date">
  <label>Some Date</label>
  <occurrences minimum="0" maximum="1"/>
  <default>2011-09-12</default>
</input>
common fields
All Input Types have these Common Fields
default

The format for the default date value can be:

  • Date in ISO 8601 format: yyyy-MM-dd (e.g. “2016-12-31”)
  • Relative date expression (e.g. “+1year -12days”)

A relative date expression is a sequence of one or more date offsets. An offset consists of: a plus or minus sign, followed by an integer, followed by a date unit string (e.g. “+3 days”)

The date unit can be expressed as a singular unit, plural unit, or initial letter:

“year” “years” “y”
“month” “months” “M”
“week” “weeks” “w”
“day” “days” “d”

An offset can also be the string now, which means current date.

DateTime

A simple field for dates with time. A pop-up box with a calendar and time selector allows easy editing. The format is yyyy-MM-dd hh:mm for example, 2015-02-09T09:00. The date-time could be of type local (no datetime) or with a timezone. This is done using configuration:

  <input name="name" type="DateTime">
    <label>DateTime (with tz)</label>
    <occurrences minimum="0" maximum="1"/>
    <config>
      <timezone>true</timezone>
    </config>
  </input>
common fields
All Input Types have these Common Fields
timezone
true if timezone information should be used. Default is false.
default

The format for the default date value can be:

  • Combined date and time in ISO 8601 format, with timezone: yyyy-MM-ddThh:mm±hh:mm (e.g. “2016-12-31T23:59+01:00”)
  • Combined date and time in ISO 8601 format, without timezone: yyyy-MM-ddThh:mm (e.g. “2016-12-31T23:59”)
  • Relative datetime expression (e.g. “+1year -12hours”)

Note that the ISO8601 format consists of concatenating a complete date expression, the letter T as a delimiter, and a valid time expression.

The timezone offset is a plus or minus sign, followed by an hour offset, followed by a colon, followed by a minute offset. A timezone offset of zero can also be represented as ‘Z’, meaning UTC or Zulu time. It is equivalent to offset +00:00.

A relative date expression is a sequence of one or more datetime offsets. An offset consists of: a plus or minus sign, followed by an integer, followed by a date/time unit string (e.g. “+3 days”)

The date unit can be expressed as a singular unit, plural unit, or initial letter:

“year” “years” “y”
“month” “months” “M”
“week” “weeks” “w”
“day” “days” “d”
“hour” “hours” “h”
“minute” “minutes” “m”

An offset can also be the string now, which means current date and time.

Examples:

<input name="dateTimeDefaultTz" type="DateTime">
  <label>DateTime (with tz and default value)</label>
  <config>
    <timezone>true</timezone>

default

The format for the default time value can be:

  • Time in 24h format: hh:mm (e.g. “23:59”)
  • Relative time expression (e.g. “+1hour -12minutes”)

A relative time expression is a sequence of one or more time offsets. An offset consists of: a plus or minus sign, followed by an integer, followed by a time unit string (e.g. “+3 minutes”)

The time unit can be expressed as a singular unit, plural unit, or initial letter:

“hour” “hours” “h”
“minute” “minutes” “m”

An offset can also be the string now, which means current time.

Item Sets

Item sets represent a special capability of forms that allow you to nest other form items hierarchically.

Inputs in item sets are grouped into logical units, allowing them to repeat as a complex input type - since item sets support occurrences too. Item sets are both visually and semantically grouped as the name of the item set is used in the persisted property structure. An item set actually produces a property set.

Here is an example of an item set with two inputs. The resulting form will allow multiple entries of phone numbers with labels:

<item-set name="contact_info">
  <label>Contact Info</label>
  <items>
    <input name="label" type="TextLine">
      <label>Label</label>
      <occurrences minimum="0" maximum="1"/>
    </input>
    <input name="phone_number" type="TextLine">
      <label>Phone Number</label>
      <occurrences minimum="0" maximum="1"/>
    </input>
  </items>
  <occurrences minimum="0" maximum="0"/>
</item-set>
name (required)
The set needs a name for reference in result sets.
label
The set label is printed as a header on the box that will surround the group in the input form.
occurrences
Occurrence configuration can be done at any level.

Tip

It is also possible to nest item sets inside each other

Option Sets

An option set represents a group of options rendered as either radio-buttons or checkboxes. Each option may or may not have a form of inputs it consists of. An option can be considered to be a field-set with selectable header.

By default, an option form will only be shown upon selection of the option, but the entire option set may be configured to have all of its options expanded by default.

It’s also possible to pre-select specific options by default.

Here is an example of a multi-select option set with options expanded by default, empty first option and pre-selected second option:

<option-set name="checkOptionSet">
  <label>Multi-selection OptionSet</label>
  <expanded>true</expanded>
  <occurrences minimum="1" maximum="1"/>
  <help-text>You can select up to 2 options</help-text>
  <options minimum="1" maximum="2">
    <option name="option_1">
      <label>Option 1</label>
      <help-text>Help text for Option 1</help-text>
    </option>
    <option name="option_2">
      <label>Option 2</label>
      <default>true</default>
      <items>
        <input name="contentSelector" type="ContentSelector">
          <label>Content selector</label>
          <occurrences minimum="0" maximum="0"/>
          <config/>
        </input>
      </items>
    </option>
    <option name="option_3">
      <label>Option 3</label>
      <help-text>Help text for Option 3</help-text>
      <items>
        <input name="textarea" type="TextArea">
          <label>Text Area</label>
          <occurrences minimum="0" maximum="1"/>
        </input>
        <input name="long" type="Long">
          <label>Long</label>
          <indexed>true</indexed>
          <occurrences minimum="0" maximum="1"/>
        </input>
      </items>
    </option>
  </options>
</option-set>
@name (required)
The set needs a name for reference in result sets.
label
The label is displayed as a header of the option set.
expanded
Optional. Set to true to expand all of the options by default
occurrences
Detailed definition of how many times this option set may be repeated inside one content.
help-text
Optional. Help text for the entire option set.
options (required)

Container of options.

@minimum
Required. Minimum number of options that must be selected in this option set.
@maximum
Required. Maximum number of options that can be selected in this option set. Setting this attribute to a value greater than 1 will result in rendering of a multi-select option set with options rendered as checkboxes. Setting the attribute value to 1 will render options as radio-buttons (single-select option set). Once the maximum of selected options is reached, the rest of the options will be disabled.
option (required)

Container of the option form.

@name (required)
Option name. Must be unique within the option set.
label (required)
Label of the option’s checkbox or radio button.
help-text
Optional. Help text for the option.
default
Optional. Set to true to pre-select the option.
items
Optional. Container of the option form’s inputs.

Schema Layouts

To shape the presentation of a form, one can use layouts. Currently, only one layout exists.

Field set

A field set may be used to group items visually. The example below will create a form in the admin console with the inputs grouped under the label of the field set.

<field-set name="metadata">
  <label>Metadata</label>
  <items>
    <input name="tags" type="Tag">
      <label>Tags for tag cloud</label>
      <occurrences minimum="0" maximum="5"/>
    </input>
  </items>
</field-set>
@name (required)
The field set needs a name for reference.
label
The label will appear as a heading above the inputs that are grouped inside.
items
The fields inside the set must be listed inside an items element.

Mixins

Structures of data that are repeated in different content types or component descriptors may be defined as mixins. Such structures (like some address fields or a combobox with a standard set of values) would be defined once in a mixin and then the mixin would be called in other schemas that require these fields. The mixin definition file must be placed in the folder site/mixins/[name] and named [name].xml. For example, site/mixins/us-address/us-address.xml.

<mixin>
  <display-name>U.S. Address format</display-name>
  <items>
    <input type="TextLine" name="addressLine">
      <label>Street address</label>
      <occurrences minimum="0" maximum="2"/>
    </input>
    <input type="TextLine" name="city">
      <label>City</label>
      <occurrences minimum="1" maximum="1"/>
    </input>
    <input type="TextLine" name="state">
      <label>State</label>
      <occurrences minimum="0" maximum="1"/>
    </input>
    <input type="TextLine" name="zipCode">
      <label>Zip code</label>
      <occurrences minimum="0" maximum="1"/>
    </input>
  </items>
</mixin>

Tip

A mixin may optionally have its own specific icon. The icon can be assigned to the mixin by adding a PNG file with the same name, in the mixin folder, e.g. site/mixins/us-address/us-address.png

Using a mixin

Below is an example of a simple content type that uses the us-address mixin (inline) and the menu-item mixin (x-data). Notice that the name of the mixin file is used and not the mixin’s Display Name.

<content-type>
  <display-name>Using mixins</display-name>
  <super-type>base:structured</super-type>
  <form>
    <inline mixin="us-address"/>
  </form>
  <x-data mixin="menu-item"/>
</content-type>
inline
When a mixin is added with the inline element, the inputs will be included with the content data. Inline mixins can be used in content types, component descriptors, and the site.xml file.
x-data
Mixins can also be added with an x-data element in content types and the site.xml file. Be aware that any x-data inputs added to the site.xml file will be applied to all content types in the site.

Relationship Types

Note

Relationship types are optional and experimental, they currently do not provide relevant functionality to your projects

Custom content types may have relationships to each other or other content types. For instance, a person may have an image, or an employee may have a boss, or belong to a department. These relationships must be defined with a specific relationship type, then used in the custom content with an input type ContentSelector. The relationship type definition is an XML file. It must be placed in the folder, site/relationship-types/[name] and be named [name].xml. Here is an example of a relationship-type:

<relationship-type>
  <display-name>Citation</display-name>
  <from-semantic>citation in</from-semantic>
  <to-semantic>cited by</to-semantic>
  <allowed-from-types/>
  <allowed-to-types>
    <content-type>com.enonic.xp.modules.features:article</content-type>
  </allowed-to-types>
</relationship-type>
from-semantic
Text to describe the “from” relationship.
to-semantic
Text to describe the “to” relationship.
allowed-from-types
Any content type may use this relationship-type.
allowed-to-types
Wherever this relationship-type is used, only an article may be selected.

The content types have the format module-name:content-type-name. The module may be system for built-in types.

Tip

A relationship type may optionally have its own specific icon. The icon can be assigned to the relationship type by adding a PNG file with the same name, in the relationship type folder, i.e. site/relationship-types/[name]/[name].png

System relationship types

There are two default relationship types that may be used out of the box. These represent general relationship types that may be reused often.

system:reference
No content type restriction, from-semantic = “relates to”, to-semantic = “related of”.
system:parent
No content type restriction, from-semantic = “parent of”, to-semantic = “child of”.

Forms

The main purpose of the schema concept is to construct forms that can be edited through the admin interface or used programmatically, without coding a custom interface and complex controllers. A form is basically a composition of layouts and input types. When a form is populated and submitted, the result will be a basic property structure that can be stored directly into Nodes.

Some hands on examples where forms are used in the system are Content Types and Sites.

Basic Setup

Forms can be defined through Java or XML, where the latter is the most common.

Below is an example configuration in xml:

<form>
  <input name="choice1" type="ComboBox">
    <label>Choice1</label>
    <occurrences minimum="0" maximum="1"/>
    <config>
        ...
    </config>
  </input>
</form>
Adding Mixins

To simplify maintenance of forms, mixins can be created and injected into a form simply by referencing it. The form will render as if everything in the mixin was written directly in the form itself. Read more about Mixins.

<form>
  <field-set name="basic">
    <label>Status</label>
    <items>
      <inline mixin="us-address"/>
    </items>
  </field-set>
</form>

Serverside JavaScript

Enonic XP primarily uses server-side JavaScript for application development. Our goal is to enable any developer - PHP, .net, Java, Python, etc, etc to quickly be productive with Enonic XP.

Here are some highlights on how it works:

  • Runs on the Java Virtual Machine using the Nashorn JavaScript engine, a high performance, portable and robust platform.
  • Multithreaded request-response approach - simplifying software development and utilization of modern multi-core hardware
  • Implements central parts of CommonJS module specification (http://wiki.commonjs.org/wiki/Modules/1.1) like RequireJS - but not all
  • You can invoke Java directly from your scripts - quickly accessing powerful Java libraries

Beyond simply executing JavaScript on the server, the XP framework provides a range of capabilities, primarily associated with HTTP. Read more below to learn about the basic concepts.

HTTP Controllers

Serverside JavaScript is used in the http controllers of Enonic XP. Every Page, Part, Layout, Services, Controller Mappings etc. must have a controller.

An application may also contain an Application Controller.

JavaScript controllers are invoked from the portal by exporting functions matching the desired HTTP Method it implements. As such, any controller must explicitly declare one or more “exports” in order to handle requests: GET, POST, DELETE are examples of such methods.

The appropriate function will automatically be invoked for every request sent to the controller.

Example usage

// Handles a GET request
exports.get = function(req) {}

// Handles a POST request
exports.post = function(req) {}

A handler function receives a parameter with a request object, and returns a response object.

exports.get = function(request) {

  if (request.mode === 'edit') {
    // do something...
  }

  var name = request.params.name;
  log.info('Name = %s', name);

  return {
    body: 'Hello ' + name,
    contentType: 'text/plain'
  };

};

Global JavaScript objects and functions

The following global functions and objects are available in the Enonic XP framework.

App

The globally available app object holds information about the contextual app it was delivered from.

app.name
Name of the application.
app.version
Version of the application.
app.config
Application configuration. This can be set using
``$XP_HOME/config/<app.name>.cfg``. Every time the configuration is
changed the app is restarted.

Examples:

// Get application name
var name = app.name;  // com.enonic.app.superhero

// Get application version
var version = app.version;  // 1.2.0
Log

This globally available log object holds the logging methods. It’s one method for each log level and takes the same number of parameters.

log.debug(message[, args])
Arguments:
  • message (string) – Message to log as a debug-level message.
  • args (array) – Optional arguments used in message format.
log.info(message[, args])
Arguments:
  • message (string) – Message to log as an info-level message.
  • args (array) – Optional arguments used in message format.
log.warning(message[, args])
Arguments:
  • message (string) – Message to log as a warning-level message.
  • args (array) – Optional arguments used in message format.
log.error(message[, args])
Arguments:
  • message (string) – Message to log as an error-level message.
  • args (array) – Optional arguments used in message format.

Examples:

// Log a simple message
log.debug('Hello World');

// Log a formatting message
log.info('Hello %s', 'World');

// Log a formatting message
log.warning('%s %s', 'Hello', 'World');

// Log using the built-in JSON converter
log.error('My JSON %s', object );
Resolve()

This globally available function resolves a fully qualified path to a local resource based on the current location. It does not check if a resource exists at the specified path. This function supports both relative (with dot-references) and absolute paths.

resolve(path)
Arguments:
  • path (string) – Path to resolve using current location.
Returns:

The fully qualified resource path of the location.

Examples:

// Absolute path
var path1 = resolve('/views/myview.html');

// Relative path - in this case, the resource must be in the same folder
var path2 = resolve('myview.html');

// Relative path (same as above)
var path3 = resolve('./myview.html');

// Relative path - resource is one level up
var path4 = resolve('../myview.html');
Require()

This globally available function will load a JavaScript file and return the exports as objects. The function implements parts of the CommonJS Modules Specification.

require(path)
Arguments:
  • path (string) – Path to the JavaScript to load.
Returns:

The loaded JavaScript object exports.

Examples:

// Absolute path
var lib1 = require('/lib/mylib.js');

// Relative path
var lib2 = require('mylib');

// Relative path (same as above)
var lib3 = require('./mylib.js');

// Relative path
var lib4 = require('../mylib');

If the path is relative then it will start looking for the file from the local directory. If the file is not found there, it will start scanning in parent directories that have a /lib folder until it reaches the resources/ folder. The file extension .js is not required.

Exports

The globally available exports keyword is used to expose functionality from a given JavaScript file (controllers, libraries etc). This is part of the require.js spec.

Simply use the exports keyword to expose functionality from any JavaScript file.

Double underscore __

The double underscore is available in any server-side JavaScript code and is used for wrapping Java objects in a JavaScript object. Read more about Invoking Java.

Main Initializer

When an application starts it can trigger some code. If you add a main.js file to the root of your application (/src/main/resources/) this file is executed when the application starts. Here it’s possible to add various initialization code or add event listeners to listen for events.

Simple example:

// Log application started
log.info('Application ' + app.name + ' started');

Running code on stop:

// Log application started
log.info('Application ' + app.name + ' started');

// Log when application is stopped
__.disposer(function() {
    log.info('Application ' + app.name + ' stopped');
});

HTTP Request

The following object is passed along with every HTTP request. The object is similar to many traditional request objects, except for two special properties: mode and branch. These properties are specific to the XP Portal, automatically indicating the contextual branch and rendering mode.

The request object represents the HTTP request and current context for the controller.

{
  "method": "GET",
  "scheme": "http",
  "host": "enonic.com",
  "port": "80",
  "path": "/my/page",
  "url": "http://enonic.com/my/page?debug=true",
  "remoteAddress": "10.0.0.1",
  "mode": "edit",
  "branch": "master",
  "params": {
    "debug": "true"
  },
  "headers": {
    "Language": "en",
    "Cookies": "mycookie=123; other=abc;"
  },
  "cookies": {
    "mycookie": "123",
    "other": "abc"
  }
}
method
HTTP method of the request.
scheme
Name of the scheme used to make this request (“http” / “https”).
host
Host name of the server to which the request was sent.
port
Port of the server to which the request was sent.
path
Path of the request.
url
URL of the request.
remoteAddress
IP address of the client that sent the request. If the X-Forwarded-For header is set, its value will override the client IP.
mode
Portal rendering mode, one of: edit, preview, live.
branch
Name of the repository branch, one of: draft, master.
body
Optional text value
params
Name/value pairs with the query/form parameters from the request.
headers
Name/value pairs with the HTTP request headers.
cookies
Name/value pairs with the HTTP request cookies.

HTTP Response

The response object is the value returned by an HTTP controller - as a response to an HTTP Request.

{
  "status": 200,
  "body": "Hello World",
  "contentType": "text/plain",
  "headers": {
      "key": "value"
  },
  "cookies": {},
  "redirect": "/another/page",
  "pageContributions": {},
  "postProcess": true,
  "applyFilters": true
}
status
HTTP response status code (default is 200).
body
HTTP message body of the response that can either be a string or a JavaScript object.
contentType
MIME type of the body (defaults to text/plain; charset=utf-8).
headers
Name/value pairs with the HTTP headers to be added to the response.
cookies
HTTP cookies to be added to the response. Will be described in a later section.
redirect
URI to redirect to. If specified, the value will be set in the “Location” header and the status will be set to 303.
pageContributions
A special filter available for sites and page components allowing page components to contribute html to the main page markup. See Page Contributions
postProcess
Post-processing is a special filter for sites and pages, if enabled it will reprosess a page looking for page contributions and rendering components in a page. (See also Page Contributions) (default is true). Set to false if you want to speed up page rendering in cases where there are no regions or page components.
applyFilters
Whether or not to execute the filters after rendering. Set to false to skip execution of filters. (See also Response Filters) (default is true).

HTTP Cookies

There are two ways that Http Cookie values can be set in responses (see examples).

  • If the value is a string (1) then the cookie is created using default settings.
  • If the value is an object (2) then it will try to apply the settings. Every field is optional except “value”.

Here’s an example of how the cookies should be set:

return {
    status: 200,
    body: "Hello World",
    cookies: {
        "plain": "value", // Example (1) of just setting a value
        "complex": { // Example (2) for using a full JS object
            value: "value",
            path: "/valid/path",
            domain: "enonic.com",
            comment: "Some cookie comments",
            maxAge: 2000,
            secure: false,
            httpOnly: false
        }
    }
};
Settings

Overview of full JS object and the settings can be found here. A full in-depth into how each parameter works can be found in the Java documentation for Cookies. Also, general knownledge of Cookies and their limitations is adviced.

value (required)
The value to store in the cookie. The example (2) in the code above would create a cookie looking like this complex: value.
path

The paths on the site this cookie should be available from (and all containing paths).

Default: empty (The entire site can read the cookie.)

domain

Add additional sites that should be able to read the cookie.

Default: empty (Only the server that creates the cookie can read it.)

comment

A comment describing the cookie.

Default: null

maxAge

Number of seconds before the browser is allowed to delete the cookie.

Default: -1 (The cookie will live until the browser is shut down.)

secure

Control if the cookie should only be accepted to be created and read over https and similar secure protocols.

Default: false

httpOnly

Control if the cookie is available for scripts or not. If true, only the serverside code can read the cookie.

Default: false (Also client-side scripts can read the cookie.)

Websockets

Warning

Websocket support is experimental.

Websocket support allows a service to act as a websocket channel that you can connect to from a web-browser.

A get method must be implemented to handle initialization of the websocket.

// Create a websocket if websocket request.
exports.get = function (req) {

  if (!req.webSocket) {
    return {
      status: 404
    };
  }

  return {
    webSocket: {
      data: {
        user: "test"
      },
      subProtocols: ["text"]
    }
  };
};

A websocket event handler named webSocketEvent is required. It will be called for every websocket event from a client. See example below.

// Listen to a websocket event
exports.webSocketEvent = function (event) {

  if (event.type == 'open') {
    // Do something on open
  }

  if (event.type == 'message') {
    // Do something on message recieved
  }

  if (event.type == 'close') {
    // Do something on close
  }

};

Below is an example of a simple chat. A library called lib-websocket has functions for sending messages back and adding/removing clients in groups. Adding to groups allows for multicast message sending.

// Lib that contains websocket functions.
var webSocketLib = require('/lib/xp/websocket');

// Listen to a websocket event
exports.webSocketEvent = function (event) {

  if (event.type == 'open') {
    // Send message back to client
    webSocketLib.send(event.session.id, 'Welcome to our chat');

    // Add client into a group
    webSocketLib.addToGroup('chat', event.session.id);
  }

  if (event.type == 'message') {
    // Propegate message to group
    webSocketLib.sendToGroup('chat', event.message);
  }

  if (event.type == 'close') {
    // Remove client from a group
    webSocketLib.removeFromGroup('chat', event.session.id);
  }

};

Invoking Java

In Enonic XP, there is a standard object named __ (double underscore), accessible from any serverside JavaScript code, which provides a way to wrap Java objects in a JavaScript object. The __ object has functions that allow JavaScript to communicate with Java classes. The newBean function will wrap the Java object named in the parameter, for instance:

var bean = __.newBean('com.enonic.xp.lib.io.IOHandlerBean');

This line is from the lib-io library, which is a good example of how this is used. In the Java IOHandlerBean class, there are several methods, like the readLines method:

public List<String> readLines( final Object value )
    throws Exception
{
    final CharSource source = toCharSource( value );
    return source.readLines();
}

This method is now accessible as a function on the JavaScript bean and may be invoked from JavaScript, like this:

exports.readLines = function (stream) {
    return __.toNativeObject(bean.readLines(stream));
};

This results in a global JavaScript function readLines. This example also shows the use of the toNativeObject method, which in this case, converts a Java String array to a JSON object. The reference documentation for the __ object can be found here: The __ object.

Application Controller

An application can implement a controller to handle HTTP requests. This is done by adding a main.js JavaScript file at the root of the application (/src/main/resources/).

The HTTP requests are handled independent of any site or content, on a specific URL with the path /app/[app-id] (e.g. “/app/com.enonic.app.superhero”).

The main.js file acts as any other controller and may expose a function for each HTTP method that should be handled: GET, POST, etc. (see HTTP Controllers). The function that handles the request receives the request object as a parameter and returns the response object .

The following is an example of an application controller, in main.js.

var mustache = require('/lib/xp/mustache');

// Handles a GET request
exports.get = function (req) {

    var view = resolve('my-page.html');
    var params = {
        appId: app.name,
        title: 'Hello world'
    };

    return {
        body: mustache.render(view, params),
        contentType: 'text/html'
    };
};

// Handles a POST request
exports.post = function (req) {
    var name = request.params.name;

    return {
        body: {'Hello': name},
        contentType: 'application/json'
    };
};

Assets

The asset files of an application (see Assets) are also available under the application controller URL.

For example, the asset in src/main/resources/assets/css/styles.css in application with name com.enonic.myapp can be requested with the URL /app/com.enonic.myapp/css/styles.css.

Assets

Applications and libraries commonly use files that will be delivered to the client (typically web browsers) without being modified. Examples are icons, css files, javascript files etc. Enonic XP provides a standard and optimized approach to serving assets across applications.

Developers simply place the files they want to use into their project’s /src/main/resources/assets/ folder. These files can then be dynamically accessed through the asset service. The asset service is typically available through _/asset/<myapp>/path/to/myasset.ext.

The assetUrl() portal function lets you easily create links to assets.

assetUrl({path [,application] [,type] [,params]})
Arguments:
  • path (string) – Path to the asset.
  • application (string) – Application where the asset exists. Default is current application.
  • type (string) – URL type. Either server (server-relative URL) or absolute. Default is server.
  • params (object) – Custom parameters to append to the url.
Returns:

The relative or absolute URL to the asset.

API

The detailed API documentation may be found here.

Services

Services allow the creation of http endpoints without binding them to specific paths. Each service must have a JavaScript controller file and optionally an XML descriptor placed in the folder services/[service-name]

Descriptor

The service descriptor is an XML file that is used to define which rights are required to access the service.

The descriptor file must have the same name as the service, i.e. services/[service-name]/[service-name].xml:

<service>
  <allow>
    <principal>role:system.admin</principal>
    <principal>role:myapp.myrole</principal>
  </allow>
</service>

Controller

A service controller handles requests to the service. The controller is a required file written in JavaScript and must have the same name as the service, i.e. services/[service-name]/[service-name].js.

A controller exports a function for each type of HTTP request that should be handled. The handle function takes the request object as a parameter and returns the response object (see HTTP Controllers).

The following example is a simple service that returns a JSON object with the date and a counter.

var counter = 0;

exports.get = function(req) {

  counter++;

  return {
    body: {
      time: new Date(),
      counter: counter
    },
    contentType: 'application/json'
  };

};

Access

The service can then be accessed on a relatively mounted URL, as seen below, where application is the application name (without version):

*/_/service/[application]/[service-name]

The portal function serviceUrl() will create a dynamic URL for a service.

serviceUrl({service [,application] [,type] [,params]})
Arguments:
  • service (string) – Name of the service.
  • application (string) – Application where the service exists. Default is current application.
  • type (string) – URL type. Either server (server-relative URL) or absolute. Default is server.
  • params (object) – Custom parameters to append to the url.
Returns:

The relative or absolute URL to the service.

API

The detailed API documentation may be found here.

Views

Instead of composing the HTML, JSON or other output in your javascript controllers, it’s often easier to use a full MVC (Model View Controller) approach.

Enonic XP supports pluggable view technologies and ships the following view libraries out-of-the-box.

Sites

Sites can be built from one (or more) applications. But only applications that contain a specific structure and a site descriptor can be used for this purpose.

This chapter will dive into the details on how to build sites and the various components of a site, such as pages and parts.

Site Descriptors

To indicate that an application provides “site capabilities” and allow it to be added to sites, a site descriptor must be placed into the application. Within your project, simply add a file called /main/src/resources/site/site.xml.

The site.xml file also makes use of the Schemas concept, so you may easily define custom forms for configuring the application when adding it to a site. These configurations are made in the <config> element.

/main/src/resources/site/site.xml
<site>
  <config>
    <input type="TextLine" name="company">
      <label>Company</label>
      <occurrences minimum="1" maximum="1"/>
    </input>
    <input type="TextArea" name="description">
      <label>Description</label>
      <occurrences minimum="1" maximum="1"/>
    </input>
  </config>
</site>

All controllers within the app can access the configured values with the portal.getSiteConfig() function.

var portal = require('/lib/xp/portal');

// Find the site configuration for this app in current site.
var siteConfig = portal.getSiteConfig();
Extensions

An app’s site.xml file may optionally contain other elements, placed outside the <config> node.

Use <x-data> element for adding Mixins. Adding a mixin this way will add that data on all the content in Content Studio.

Additionally, the <filters> element can be used for adding Response Filters.

Controller Mappings can also be configured in a site descriptor with a <mappings> element.

Content Types

To enable simple configuration and setup of publishing forms, validation and data types - Enonic XP ships with a content api. Central to this api are Content Types. Structured, indexed and searchable content items are created from Content types. Content Types build on the Forms concept, so they are very similar to other configurable forms in Enonic XP.

Content repository

Every content item produced is eventually stored as nodes in the low level storage, read more about the Storage.

A system standard repository called cms-repo is initialized when installing Enonic XP. This is where content is stored when working with content in the Content Studio application or the content-API.

The content-API actively uses the branch capabilities. The cms-repo has two branches:

  • draft
  • master

The content seen while working in Content Studio is in the draft branch. Content in the portal is served from the master branch.

Publishing a content moves it from the draft branch to the master branch.

Sample Content type

A “Person” content type might look something like this:

_images/person-cty.png

The underlying schema configuration would look like this

<?xml version="1.0" encoding="UTF-8"?>
<content-type>
  <display-name>Person</display-name>
  <super-type>base:structured</super-type>
  <form>
    <input type="imageSelector" name="photo">
      <label>Photo</label>
      <occurrences minimum="1" maximum="1"/>
    </input>
    <input type="HtmlArea" name="bio">
      <label>Bio</label>
       <occurrences minimum="1" maximum="1"/>
    </input>
    <input type="TextLine" name="email">
      <label>Email</label>
      <occurrences minimum="1" maximum="1"/>
    </input>
    <input type="TextLine" name="website">
      <label>Website</label>
      <occurrences minimum="0" maximum="1"/>
    </input>
    <input type="TextLine" name="twitter">
      <label>Twitter Name</label>
      <occurrences minimum="0" maximum="1"/>
    </input>
    <input type="TextLine" name="facebook">
      <label>Facebook Name</label>
      <occurrences minimum="0" maximum="1"/>
    </input>
  </form>
</content-type>

And the persisted (and searchable node) would look like this: NB! The content type defined properties are stored within the ‘data’ propertySet.

Base Content Types

A set of basic content types are provided with the installation.

Content types have a set of properties you need to know about:

  • Content types are named with their application name, i.e. base:folder, where “base” is the application - but also have a nice display name like “Folder”
  • abstract (default: false) means you cannot create content with this content type
  • final (default: false) means it is not possible to create content types that “extend” this
  • allow-child-content (default: true) if false, it will prevent users from creating child items on content of this type. (i.e. prevents creating child items of images)
Folder (base:folder)
  • abstract: false
  • final: false
  • allow-child-content: true

Folders are simply containers for child content, with no other properties than their name and Display Name. They are helpful in organizing your content.

Media (base:media)
  • abstract: true
  • final: false
  • allow-child-content: false

This content type serves as the abstract supertype for all content types that are considered “files” in their natural habitat. These are listed on the Media Content Types page.

Shortcut (base:shortcut)
  • abstract: false
  • final: true
  • allow-child-content: true

This is used for redirecting a visitor to another content item in the structure. Optional name-value parameters can be set to be added to the redirect URL.

Structured (base:structured)
  • abstract: true
  • final: false
  • allow-child-content: true

This is possibly the most commonly used base type for creating other content types. The structured content type is the foundation for basically any other structured content you can come up with, such as the Person content in the previous example.

Unstructured (base:unstructured)
  • abstract: false
  • final: true
  • allow-child-content: true

The unstructured content type is a special content type that permits the creation of any property or structure without actually defining it first. This is convenient for user generated content from forms on a site.

Caution

There is currently no UI for unstructured content so they will appear empty in the admin console. However, a custom page template that supports base:unstructured may easily be created to show name/value pairs.

Media Content Types

The system ships with a set of pre-defined media content types. When files are uploaded in the Content Studio interface or through the content API - they will be transformed to one of the following content-types.

Common settings for all the content types listed below.

  • super-type: base:media
  • abstract: false
  • final: true
  • allow-child-content: false

Tip

Enonic XP treats media content pretty much like any other content items - for instance the person, but they all have at least one attachment (namely the file).

_images/upload-button.png

Here are the various media content types that also come installed with Enonic XP:

Text (media:text)
Plain text files.
Data (media:data)
Miscellaneous binary file formats.
Audio (media:audio)
Audio files.
Video (media:video)
Video files.
Image (media:image)
Bitmap image files.
Vector (media:vector)
Vector graphic files like .svg.
Archive (media:archive)
File archives like .zip, tar and jar.
Document (media:document)
Text documents with advanced formatting, like .doc, .odt and pdf.
Spreadsheet (media:spreadsheet)
Spreadsheet files.
Presentation (media:presentation)
Presentation files like Keynote and Powerpoint.
Code (media:code)
Files with computer code like .c, .pl or .java.
Executable (media:executable)
Executable application files.
Unknown (media:unknown)
Everything else.
Portal content types

In order to build sites in a secure and fashionable manner, Enonic XP also ships with a few special purpose content types.

Site (portal:site)
  • super-type: base:structured
  • abstract: false
  • final: true
  • allow-child-content: true

The Site content type allows creating websites. By creating a content of type Site, it will become the root of a website.

This content type provides a special behavior for the content, allowing to select and configure applications for the website. The types (content types, relationship types and mixins) of the applications selected will be available to be used inside the website content tree.

Note

The content types of an application can only be used under a content of type Site which has the application selected.

Page Template (portal:page-template)
  • super-type: base:structured
  • abstract: false
  • final: true
  • allow-child-content: true

Page templates are the equivalent of “master slides” in keynote and powerpoint. They enable you to set up pages that will be used when presenting other content types. From the sample content type above, the page template “Person Show” was taking care of the presentation.

Template folder (portal:template-folder)
  • super-type: base:folder
  • abstract: false
  • final: true
  • allow-child-content: portal:page-template only

This is a special content-type. Every site automatically creates a child content of this type named _templates. The templates folder holds all the page templates of that site. It may not hold any other content type, and it may not be created manually in any other location.

Fragment (portal:fragment)
  • super-type: base:structured
  • abstract: false
  • final: true
  • allow-child-content: true

The Fragment content type represents a reusable page component. A content of this type contains a page component(Part, Layout, Text, Image) that can be re-used in other pages. But it only needs to be maintained in one place.

To create a content of type portal:fragment edit an existing page with Page Editor, select the context menu of an existing component in the page, and then clicking on “Create Fragment”. Once created, the fragment content can be referenced in other pages by inserting a Fragment component in the page.

A Fragment content can be edited with Page Editor and the changes applied to the component will immediately be available in the pages that include the fragment. When a page containing fragment a component is rendered, the components of the portal:fragment content pointed by the fragment component are rendered in the place of the fragment component.

There is a default page for rendering and edit fragments. The default page does not have any styles defined, but it is possible to render it with the application theme and styles by defining a controller mapping with <match>type:'portal:fragment'</match> (See Controller Mappings).

Custom Content Types

Custom Content Types can be created using Java or simple xml files - and deployed through applications.

When using xml, each content type must have a separate folder in the application resource structure. i.e. site/content-types/<my-content-type-name>.

Each folder must then hold a file with the name of the content type and .xml extension (e.g. my-content-type-name.xml).

This is the basic structure of a content-type.xml file:

<content-type>
  <display-name>Choices</display-name>
  <content-display-name-script>$('firstName', ' ', 'lastName')</content-display-name-script>
  <super-type>base:structured</super-type>
  <is-abstract>false</is-abstract>
  <is-final>true</is-final>
  <allow-child-content>true</allow-child-content>
  <form>
    <input name="choice1" type="ComboBox">
      <label>Choice1</label>
      <occurrences minimum="0" maximum="1"/>
      <config>
          ...
      </config>
    </input>
  </form>
</content-type>
display-name
The display name of the content type is used throughout the admin console to recognize it. But the technical name is the name of the folder the file is placed in.
super-type
Many properties are inherited from the super-type. All custom content types must either inherit base:structured directly or indirectly. The icon and the general form to edit the fields of the content are important properties that are inherited from base:structured.
is-abstract
If a content type is abstract, no content of this type may be instantiated. It may still be used as a super type for other content types.
is-final
Final content types may not be used as super types of other content types.
allow-child-content
Default is true, which allows nodes to be added in the tree below a content of this type.
form
Fields in the content type are defined as input elements which are placed inside the form element. All legal input types are described below.
input
name and type are mandatory attributes of the input element. label and occurrences are mandatory child elements.
config
Some input types have a complex configuration that is defined inside a config element. It is mandatory for the content types that need it.
content-display-name-script
The name of a content may be generated by JavaScript from the values in the form, including values that are added through a mixin.

Tip

A content type may optionally have its own specific icon. The icon can be assigned to the content type by adding a PNG or SVG file with the same name, in the content type folder, e.g. site/content-types/my-content-type-name/my-content-type-name.svg

Response Filters

Response filters are scripts, similar to controllers, that allow customizing or adapting the response of page controllers. Notice that this actually applies to pages from any application added to the site.

The page and component controllers are processed during rendering and then the response filters will be executed afterward.

To add a response filter, create a folder site/filters in the application and place a [filter-name].js file within this folder. A filter must export a method named responseFilter. This method receives the request and response objects as parameters and must return a response object (see HTTP Controllers).

Here is an example of a [filter].js file:

site/filters/trackingScript.js
exports.responseFilter = function (req, res) {
    var trackingScript = '<script src="http://some.site/js/tracking.js"></script>';

    var bodyEnd = res.pageContributions.bodyEnd;
    if (!bodyEnd) {
        res.pageContributions.bodyEnd = [];
    }
    if (typeof bodyEnd == 'string') {
        res.pageContributions.bodyEnd = [ bodyEnd ];
    }
    res.pageContributions.bodyEnd.push(trackingScript);

    if (req.params.debug === 'true') {
        res.applyFilters = false; // skip other filters
    }

    return res;
};

In addition, the filter must be declared in the site.xml descriptor by adding a <response-filter> element within the <filters> element, with @name and @order attributes.

site/site.xml
<?xml version="1.0" encoding="UTF-8"?>
<site>
  <filters>
    <response-filter name="trackingScript" order="10"/>
  </filters>
  <x-data mixin="html-meta"/>
  <config>
    <input type="ContentSelector" name="profiles">
      <label>Profiles folder</label>
      <occurrences minimum="0" maximum="1"/>
      <config>
        <relationshipType>system:reference</relationshipType>
        <allowContentType>base:folder</allowContentType>
      </config>
    </input>
  </config>
</site>

Response filters may change any of the values of the response object, that includes: HTTP status code, response body, HTTP headers, cookies and page contributions.

It is also possible to return the response object received without any changes.

Execution order

An application can contain multiple filters declared in site.xml. Multiple applications can be selected for a Site. When a page is rendered, all the filters declared in all the applications selected for the site will be executed. The order in which the filters are executed depends on the filters order (as defined in site.xml) and the order of the applications configured on the Site.

The filters with a lower order will be executed first. In case there are several filters with the same order number, the position of the applications (as configured for a Site in Content Studio) determines the order of execution.

The filter-chain execution can be interrupted from either a controller or a filter by setting the applyFilters field in the response. When this value is set to false all of the remaining filters will be skipped. (See HTTP Response).

Controller Mappings

Controller mappings allow the creation of HTTP endpoints that are bound to a combination of a URL pattern and/or content property.

The mappings can be defined in the site.xml file (see Site Descriptors).

<site>

  <mappings>
    <mapping controller="/site/foobar/api.js" order="10">
      <!-- URL relative to site path, e.g.:  [site-path]/api/v42/action -->
      <pattern>/api/v\d+/.*</pattern>
    </mapping>

    <!-- handle fragment content-type -->
    <mapping controller="/site/pages/default/default.js">
      <match>type:'portal:fragment'</match>
    </mapping>
  </mappings>

</site>

Multiple mappings can be set for a site.

Each controller mapping has the following properties:

  • Controller: application path to the JavaScript controller that will handle the request. This attribute is required.
  • Content match: matching condition to evaluate on the content in the requested path. This element is optional.
  • URL pattern: regular expression to match against the request URL. This element is optional.
  • Order: determines which controller will be executed in case there is more than one that matches. The mapping with lowest order value will be executed. Default is 50.

Controller mappings can be used for rendering fragments, i.e. contents of type portal:fragment, with custom styles and layout. That way they will be consistent with the other page components in the application (see Portal content types). This is useful for editing fragments from Page Editor in Content Studio.

Controller

The controller is specified with the controller attribute in a <mapping> element. A controller handles requests in the same way a Page or a Part controller does. The controller is a JavaScript file located in the application.

Unlike page and part controllers, a mapping controller is not required to be placed in a specific directory. In fact, an existing page or service controller can also be used as the controller for a mapping.

The controller must export a method for each type of HTTP request that should be handled. The handle method receives the request object as a parameter and returns the response object (see HTTP Controllers).

Example: <mapping controller="/site/controller/foo.js">

Content match

The <match> element specifies a condition related to the content corresponding with the requested URL path.

The condition takes the form of a property path followed by a semicolon, and then an expected value.

The property path can be one of the content properties (_id, _name, _path, type, displayName, hasChildren, language, valid) or a custom property in the data or x part.

Examples:

<match>type:'portal:fragment'</match>
<match>_path:'/features/.*'</match>
<match>data.employee.type:'developer'</match>
<match>data.product.category:42</match>
<match>x.com-enonic-myapp.menuItem.show:true</match>

The expected value can be either a regular expression to match the property value, or simply a string, number or boolean (true | false).

URL pattern

The <pattern> element specifies a regular expression to be matched against the request URL. The part of the URL that is taken into account for the matching is the path relative to the site where the application is configured. For example, if a site has a content path /mysite, then the pattern <pattern>/api/.*</pattern> will match with requests with URL ending in /mysite/api/.*

If the pattern contains the question mark ? character, the URL to match will also include query parameters. The query parameters will be normalized so they are always in alphabetical order.

For example the pattern <pattern>/api\?category=foo&amp;key=\d+</pattern> will match with both:

/api?category=foo&key=123 and also with /api?key=123&category=foo

Note than in the previous example the question mark character ? is escaped with a backslash because the question mark is a quantifier in regular expressions. And also the ampersand character & needs to be XML-escaped because the pattern string is in an XML. Another alternative to XML-escape is to wrap the string in a CDATA block, as in the example below.

The protocol, host and port are not involved in the matching.

The pattern element may also contain an invert attribute to indicate that the result of evaluating the regular expression should be negated: <pattern invert="true">

The pattern string must be a valid Java regular expression.

Examples:

<pattern>/api/.*\.json</pattern>
<pattern>/.*</pattern>
<pattern><![CDATA[/endpoint\?bar=\d+&foo=.*]]></pattern>
<pattern>/endpoint\?bar=\d+&amp;foo=.*</pattern>
<pattern invert="true">/section/.*</pattern>

Page

A page component is the most basic building block of a site. Each page component must have a JavaScript controller file and optionally an XML descriptor and an HTML view file. These files can define regions in the page where parts and layouts may be added, or they can define a simple page without any compositions. Page components can be added to content individually through the Content Studio interface or they can be used to create page templates that automatically render supported content types.

Any number of page templates can be created from a single page component. Thanks to the magic of page templates, even very large sites will typically have very few page components–perhaps one for all the HTML pages and one for RSS pages.

Pages should be placed in the folder site/pages/[page-name]

Descriptor

The page descriptor is an XML file that is used to define regions and custom input fields for page configuration. If a page does not require regions or configuration options then the descriptor may be omitted.

The file must be named [page-name].xml. For example, if a page component is named “default” then the file must reside at site/pages/default/default.xml.

<page>
  <display-name>My first page</display-name>
  <config>
    <!-- input fields... -->
  </config>
  <regions>
    <region name="top"/>
    <region name="bottom"/>
  </regions>
</page>
display-name
A simple human readable display name.
config
The config element is where input fields are defined for configurable data that may be used on the page.
regions
This is where regions are defined. Various component parts can be dragged and dropped into regions on the page.
Controller

A page controller handles requests to the page. The controller is a required file written in JavaScript and must be named [page-name].js. A controller exports a method for each type of HTTP request that should be handled. The handle method has the request object as a parameter and returns the response object (see HTTP Controllers).

// Handles a GET request
exports.get = function(req) {}

// Handles a POST request
exports.post = function(req) {}

Here’s a simple controller that acts on the GET request method.

exports.get = function(req) {

  return {
    body: '<html><head></head><body><h1>My first page</h1></body></html>',
    contentType: 'text/html'
  };

};
Render-view

If you feel like concatenating strings to create an entire web page is a little too much hassle, Enonic XP also supports views. A view is rendered using a rendering engine; we currently support XSLT, Mustache and Thymeleaf rendering engines. This example will use Thymeleaf.

To make a view, create a file my-first-page.html in the view folder.

<!DOCTYPE html>
<html>
  <head>
  </head>
  <body>
    <h1>My first page, with a view!</h1>
  </body>
</html>

In our [page-name].js file, we will need to parse the view to a string for output. Here is where the Thymeleaf engine comes in. Using the Thymeleaf rendering engine is easy; here is how we do it.

var thymeleaf = require('/lib/xp/thymeleaf');

exports.get = function(req) {

  // Resolve the view
  var view = resolve('/site/view/my-first-page.html');

  // Define the model
  var model = {
    name: "John Doe"
  };

  // Render a thymeleaf template
  var body = thymeleaf.render(view, model);

  // Return the result
  return {
    body: body,
    contentType: 'text/html'
  };

};

Unlike controllers and descriptors, view files can reside anywhere in your project and have any valid file name. This allows for code reuse as multiple page components can share the same view. If the view file is in the same folder as the page controller then it can be resolved with only the file name resolve('file-name.html'). Otherwise, the full path should be used, starting with a ‘/’ as in the example above.

Dynamic-content

We can send dynamic content to the view from the controller via the model parameter of the render function. We then need to use the rendering engine specific syntax to render it. The controller file above passed a variable called name and here is how to extract its value in the view using Thymeleaf syntax.

<!DOCTYPE html>
<html>
  <head>
  </head>
  <body>
    <h1>My first page, with a view!</h1>
    <h2>Hello <span data-th-text="${name}">World</span></h2>
  </body>
</html>

More on how to use Thymeleaf can be found in the official Thymeleaf documentation.

Regions

To be able to add components like images, component parts, or text to our page via the Page Editor drag and drop interface, we need to create at least one region. Regions can be declared in the page descriptor. Each region will be referenced by name.

<page>
  <display-name>My first page</display-name>
  <config />
  <regions>
    <region name="main"/>
  </regions>
</page>

You will also need to handle regions in the controller.

var portal = require('/lib/xp/portal');

// Get the current content. It holds the context of the current execution
// session, including information about regions in the page.
var content = portal.getContent();

// Include info about the region of the current content in the parameters
// list for the rendering.
var mainRegion = content.page.regions["main"];

// Extend the model from previous example
var model = {
    name: "Michael",
    mainRegion: mainRegion
};

To make the Page Editor understand that an element is a region, we need an attribute called data-portal-component-type with the value region in our HTML.

<!DOCTYPE html>
<html>
  <head>
  </head>
  <body>
    <h1>My first page, with a view!</h1>
    <h2>Hello <span data-th-text="${name}">World</span></h2>
    <div data-portal-region="main">
      <div data-th-each="component : ${mainRegion.components}" data-th-remove="tag">
        <div data-portal-component="${component.path}" data-th-remove="tag" />
      </div>
    </div>
  </body>
</html>

We can now use the Page Editor drag and drop interface to drag components into our page.

Part

A part is a building block that can be placed in a region on a page or layout. As with pages, each part is composed of a JavaScript controller, an XML descriptor and an HTML view.

The part descriptor and controller files must be placed in the folder site/parts/[part-name]

Descriptor

The part descriptor is where input fields are defined for custom configuration of the part. The descriptor is not required if the part does not need any custom configuration. Parts cannot contain regions.

When used, the descriptor file must have the same name as the part folder that contains it site/parts/[part-name]/[part-name].xml:

<part>
  <display-name>My favorite things</display-name>
  <config>
    <field-set name="things">
      <label>Things</label>
      <items>
        <input type="TextLine" name="thing">
          <label>Thing</label>
          <occurrences minimum="0" maximum="5"/>
        </input>
      </items>
    </field-set>
  </config>
</part>
Controller

To drive this part, we will also need a controller. The controller typically uses library functions to get content and/or configurations and prepare data which it passes to the view file for dynamic rendering.

site/parts/[part-name]/[part-name].js
var portal = require('/lib/xp/portal'); // Import the portal functions
var thymeleaf = require('/lib/xp/thymeleaf'); // Import the thymeleaf render function

// Handle GET requests
exports.get = function(req) {

  // Find the current component from request
  var component = portal.getComponent();

  // Find a config variable for the component
  var things = component.config["thing"] || [];

  // Define the model
  var model = {
    component: component,
    things: things
  };

  // Resolve the view
  var view = resolve('/site/view/my-favorite-things.html');

  // Render a thymeleaf template
  var body = thymeleaf.render(view, model);

  // Return the result
  return {
    body: body,
    contentType: 'text/html'
  };

};
View

A part view defines the markup for the part component. The things parameter is basically just JSON data passed from the controller and we can iterate over it easily in Thymeleaf and print its values.

<section>
  <h2>A list of my favorite things</h2>
  <ul class="item" data-th-each="thing : ${things}">
    <li data-th-text="${thing}">A thing will appear here.</li>
  </ul>
</section>

The part can now be added to the page via drag and drop. You will be able to configure the part in the context window in live-edit.

Important

The HTML generated for the part view must have a single root element.

Layout

Layouts are used in conjunction with regions to organize the structure of the various component parts that will be placed on the page via Page Editor drag and drop. Layouts can be dropped into the page regions and then parts can be dragged into the layout. This allows multiple layouts (two-column, three-column, etc.) on the same page and web editors can change things around without touching any code. Making a layout is similar to making pages and part components. Layouts cannot be nested.

Layout contains - like pages and parts - a descriptor, a controller and a view, and should be placed in the folder site/layouts/[layout-name]

Descriptor

The layout descriptor defines regions within the layout where parts can be placed with the Page Editor. The file must be named [layout-name].xml.

<layout>
  <display-name>70/30</display-name>
  <config/>
  <regions>
    <region name="left"/>
    <region name="right"/>
  </regions>
</layout>
Controller

The layout controller composes the view of the layout based on HTTP requests. The file must be named [layout-name].js.

var portal = require('/lib/xp/portal');
var thymeleaf = require('/lib/xp/thymeleaf');

exports.get = function(req) {

  // Find the current component.
  var component = portal.getComponent();

  // Resolve the view
  var view = resolve('./layout-70-30.html');

  // Define the model
  var model = {
    leftRegion: component.regions["left"],
    rightRegion: component.regions["right"]
  };

  // Render a thymeleaf template
  var body = thymeleaf.render(view, model);

  // Return the result
  return {
    body: body,
    contentType: 'text/html'
  };

};
View

A layout view defines the markup for the layout component. The sample view below is created in Thymeleaf, but it could be created in any view engine that is supported.

<div class="row">
  <div data-portal-region="left" class="col-sm-8">
    <div data-th-each="component : ${leftRegion.components}" data-th-remove="tag">
      <div data-portal-component="${component.path}" data-th-remove="tag" />
    </div>
  </div>

  <div data-portal-region="right" class="col-sm-4" >
    <div data-th-each="component : ${rightRegion.components}" data-th-remove="tag">
      <div data-portal-component="${component.path}" data-th-remove="tag" />
    </div>
  </div>
</div>

Important

The HTML generated for the layout view must have a single root element.

Styling

For a layout to have any meaning, some styling must be applied to the view. The desired CSS should be placed in the /assets folder of the application, and included in the page where the layout should be supported. For example, the view my-first-page.html supports Bootstrap layouts:

<head>
    <meta charset="utf-8"/>
    <meta name="viewport" content="width=device-width, initial-scale=1.0"/>
    <link data-th-href="${portal.assetUrl({'_path=css/bootstrap.min.css'})}" href="../assets/css/bootstrap.min.css" rel="stylesheet"/>
</head>

Fragment

Fragments are reusable page components. A fragment can be created from an instance of one of the other four page component types: Part, Layout, Text or Image.

When created, the fragment will be stored in a content of type portal:fragment, including the component’s config. This content can then be edited independent of where it is included.

A fragment component can be inserted in any other page or layout from the same site with the Page Editor. A fragment component acts as a placeholder for the referenced fragment content. At the moment of rendering the page, the fragment is replaced by the specific component from which the fragment was created.

Unlike pages, parts, and layouts, fragment components do not require creating a descriptor in the application, since they are only placeholders for other components.

View

Content of type portal:fragment can be edited in the Page Editor as if it was a regular page. The components will be rendered inside a plain empty HTML page by default. But it is also possible to create a custom renderer with the application styles and layout.

To create a custom renderer for the portal:fragment content, configure a controller mapping in site.xml:

<site>

  <mappings>
    <mapping controller="/site/pages/default/default.js">
      <match>type:'portal:fragment'</match>
    </mapping>
  </mappings>

</site>

This mapping indicates that it will handle content of type portal:fragment.

The mapping points to a controller that will handle the rendering. The controller is just like any other page or part controller (See HTTP Controllers and Controller Mappings for details).

The custom view that will render portal:fragment content is like any other Page view, with one difference. A page has regions, but a fragment has only a component without any regions defined. To specify the component to be rendered we need to specify data-portal-component="fragment" instead of the component path.

<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" href="myStyles.css" type="text/css"/>
</head>
<body>
    <h1>Page header</h1>

    <!-- render Fragment component -->
    <div data-portal-component="fragment" data-th-remove="tag"/>

    <footer>Copyright © Enonic AS</footer>
</body>
</html>

Page Contributions

Page contributions are fragments of HTML that a component (page, part, layout) or macro can contribute to the page in which it is contained. The idea is to allow components to add JavaScript or CSS stylesheets globally in the page, although it is not restricted to scripts or styles.

Page contributions help with solving 2 problems:

  • Allow components to insert scripts or styles in specific positions in the page where it is often required.

    For example, a component providing web analytics might require that a script is inserted at the end of the page <body>. Or a stylesheet needed for a component must be inserted in the <head> tag.

  • Avoid duplicating script libraries or stylesheets required for a component. Even if the same component is included multiple times in a page, the library script contributed will only be added once.

Any page, part, layout or macro controller can contribute content to the page. The values from all component contributions will be included in the final rendered page. Duplicated values will be ignored.

There are four positions where contributed content can be inserted in the page:

  • headBegin: After the <head> opening tag.
  • headEnd: Before the </head> closing tag.
  • bodyBegin: After the <body> opening tag.
  • bodyEnd: Before the </body> closing tag.

A simple usage example:

{
  "body": body,
  "pageContributions": {
    "headEnd": "<some script />"
  }
}

A more full usage example:

{
  "body": "<html>...</html>",
  "pageContributions": {
    "headEnd": "value",
    "bodyEnd": [
      "value1", "value2"
    ]
  }
}

Some remarks:

  • All the pageContributions fields are optional. The pageContributions object is optional and each property inside is optional.
  • The value for a contribution can be a string or an array of strings.
  • The values are unique within an injection point (or tag position). If the same string is contributed from different parts, or from the same part that exists multiple times in the page, the value will only be inserted once. E.g. if two parts include a script for jQuery, it will be included once. But if one part is contributing to headBegin and another one contributes the same value to bodyEnd, then it will be inserted in both places.
  • If the tag does not exist in the rendered page, the value is ignored. I.e. if there is no <head> tag, the contributions to headBegin and headEnd will just be ignored.
  • The contributions are inserted in a post-processing step during rendering. That means that there will not be any processing of Thymeleaf tags or similar. Contributions are treated as plain text.

Warning

Avoid String - Array conflicts in response filters

When there is a single contribution for a placeholder, like headEnd, it will be a string. But adding to it in a response filter will require an array. It is best to always check if it is an array before adding a value.

var headEnd = res.pageContributions.headEnd;
if (!headEnd) {
    res.pageContributions.headEnd = [];
} else if(typeof headEnd == 'string') {
    res.pageContributions.headEnd = [ headEnd ];
}
res.pageContributions.headEnd.push(myCodeForHeadEnd);

Error Handling

Enonic XP enables you to displaying nice custom error pages for your site.

Create the following folder in your project src/main/resources/site/error and place an error.js within it. The file follows the same pattern as controllers and filters. If certain methods are implemented and exported, they will be executed in case of errors during rendering.

If an error occurs during processing - the system looks for an error.js script within the relevant application - sites specifically it will go through all applications added to the site (in order).

If an error.js script is found, it looks for an exported method named handleXXX where XXX is the HTTP status-code of the error. If not found, it will try to find the generic error method handleError instead.

Here is an example of an error.js file:

var thymeleaf = require('/lib/xp/thymeleaf');

var view404 = resolve('page-not-found.html');
var viewGeneric = resolve('error.html');

exports.handle404 = function (err) {
    var body = thymeleaf.render(view404, {});
    return {
        contentType: 'text/html',
        body: body
    }
};

exports.handleError = function (err) {
    var debugMode = err.request.params.debug === 'true';
    if (debugMode && err.request.mode === 'preview') {
        return;
    }

    var params = {
        errorCode: err.status
    };
    var body = thymeleaf.render(viewGeneric, params);

    return {
        contentType: 'text/html',
        body: body
    }
};

The input parameter for the handleXXX and handleError functions is an error JSON object containing the status code, error message, Java Exception object, and the original request object:

{
    "status": 404,
    "message": "Some error message",
    "exception": "<the actual exception object in Java>",
    "request": "<original request JSON>"
}

The expected returned value for the function is a response object (see HTTP Controllers).

The error processing logic will try every handle-function in application order until it can get a result (not undefined or null). This means that an error function can decide to not handle a specific error and let the next one deal with it. If no result is returned by any function, it will be eventually handled by the internal error page.

Also note that if an error occurs inside the custom-error code, then the internal error page will be rendered.

Macros

Warning

Macros are experimental.

Macros are instructions that allow adding extra functionality or include dynamic content in the Html Editor.

The Html Editor is used when editing HtmlArea input fields, or while editing a Text component in Page Editor.

There are two built-in macros included in XP. But its real power comes from macros provided by applications. When an application that contains macros is added to a site, they will be available for any HtmlArea or Text component inside the site.

Macro instruction

A macro instruction is similar to an HTML or XML tag but using square brackets instead of angle brackets. It has a name, a set of attributes, and optionally a body.

[macroname attrib1="value1" attrib2="value2"] body [/macroname]
[macroname attrib1="value1" attrib2="value2"/]

Macro instructions can be added anywhere in an HTML page, usually inside a content’s HtmlArea field.

During the rendering of the page the macros are resolved and executed. Then the result from executing the macro replaces the instruction text. In addition, a macro can also add styles or scripts to the page, by setting Page Contributions in its response.

A user can add macro instructions by typing the square bracket tags, as the examples above. But more frequently it will click on the Insert macro button and select one of the macros available.

Descriptor

A macro descriptor is an xml file that allows assigning a user-friendly name, and a description to the macro. It also has a configuration to define the types and names of the macro parameters.

display-name
A simple human readable display name.
description
A description to show in the Insert macro dialog in Content Studio.
config
The config element is a form where each input element corresponds to a macro parameter. The macro body is represented with an input named "body".

Note

The config form does not support nested elements, so Item Sets are not allowed in the macro config form. Also the HtmlArea input type is not allowed in the config form, since it may contain macros itself.

Its path follows the pattern site/macros/<macroName>/<macroName>.xml

<macro>
  <display-name>Current user</display-name>
  <description>Shows currently logged user</description>

  <form>
    <input name="defaultText" type="TextLine">
      <label>Text to show if no user logged in</label>
    </input>
  </form>
</macro>

Although not strictly required, it is recommended to create a descriptor, as it provides the required details for adding macros through the UI in Content Studio.

Controller

The functionality of a macro is implemented in a JavaScript controller, inside an application.

Its path follows the pattern site/macros/<macroName>/<macroName>.js

A macro controller must export a single macro function that takes a context parameter and returns a response object (see HTTP Response).

The context parameter is a Javascript object with the following properties:

name
a string containing the macro name.
body
a string containing the body of the macro instruction.
params
an object with key-value pairs containing the macro parameters. The values are the strings from the macro instruction attributes.
document
a string with the HTML document that contains the current macro. The document contains the raw source HTML, before any macro instructions have been executed, and before image or content URLs have been resolved. The document is only an input parameter to the macro, it cannot be modified.
request
the request object.
// Example usage: [currentUser defaultText="Anonymous"/]
var authLib = require('/lib/xp/auth');
var portalLib = require('/lib/xp/portal');

exports.macro = function (context) {
    var defaultText = context.params.defaultText;

    var user = authLib.getUser();
    var body = '<span>' + (user ? user.displayName : defaultText) + '</span>';

    var doc = context.document; // HTML document containing the current macro
    var lineCount = doc.split(/\r\n|\r|\n/).length;
    if (lineCount <= 1) {
        return {
            body: ''
        }
    }

    return {
        body: body,
        pageContributions: {
            headEnd: [
                '<link href="' + portalLib.assetUrl({path: 'css/current-user.css'}) + '"/>'
            ]
        }
    }
};

Note that only the body and pageContributions fields of the response are relevant for macro controllers.

Tip

A macro controller can also use libraries, like any other JavaScript controller.

Built-in macros

There are currently 2 built-in macros that are included in XP and available for any site:

disable
The contents (body) of this macro will not be evaluated as macros. That allows rendering another macro instruction as text without executing it. It is useful for documenting macros, for example. This macro has no parameters.
embed
It allows embedding an <iframe> element in an HTML area. This is a generic way for embedding content from an external source (e.g. YouTube videos). This macro has no parameters.

Examples:

[disable]Example of macro instruction: [myMacro param1="value1"/][/disable]

[embed]<iframe src="https://www.youtube.com/embed/cFfxuWUgcvI" allowfullscreen></iframe>[/embed]

Note

A macro may optionally have its own specific icon. The icon can be assigned to the macro by adding a PNG or SVG file with the same name, in the macro folder, e.g. site/macros/myMacro/myMacro.svg

Localization

Enonic XP provides a standard approach to code localizations, simply by adding resource bundles to your applications, and actively using the localize functions in “controllers” and “views”. Detailed documentation for this function is found here: localize.

Content localization currently requires building separate structures - we are working on process tools to simplify this in future releases.

To see how this is used in a controller, see lib-i18n in Javascript Libraries.

Resource Bundle

The resource-bundle consists of a collection of files containing the phrases to be used for localization. The resource-bundle should be placed in a folder named i18n under the application site folder.

Each locale to be localized should be represented by a single resource, e.g this could be a structure for an app supporting

  • ‘English’ (default)
  • ‘English US’
  • ‘Norwegian’
  • ‘Norwegian Nynorsk’
site/i18n/phrases.properties
site/i18n/phrases_en_us.properties
site/i18n/phrases_no.properties
site/i18n/phrases_no_nn.properties

The filename of a resource determines what locale it represents:

phrases[_languagecode][_countrycode][_variant].properties

Caution

The filename should be in lowercase.

The languagecode is a valid ISO Language Code. These are the two-letter codes as defined by ISO-639. You can find a full list of these codes at a number of sites, such as: http://www.loc.gov/standards/iso639-2/php/English_list.php.

The countrycode is a valid ISO Country Code. These are the two-letter codes as defined by ISO-3166. You can find a full list of these codes at a number of sites, such as: http://www.iso.ch/iso/en/prods-services/iso3166ma/02iso-3166-code-lists/list-en1.html

A sample phrases.properties file would look like this:

user.greeting = Hello, {0}!
complex_message = Good to see you. How are you doing?
message_url = http://localhost:8080/{0}
message_multi_placeholder = My name is {0} and I live in {1}
message_placeholder = Hello, my name is {0}.
med_\u00e6_\u00f8_\u00e5 = This contains the norwegian characters æ, ø and å
Placeholders

Placeholders are marked with {<number>}. The given number corresponds with the function argument named values and the placement of the parameter. See below for an example.

Encoding and special characters

The encoding of localization resource bundle files must be ISO-8859-1, also known as Latin-1. All non-Latin-1 characters in property-keys must be entered using Unicode escape characters, e.g u00E6 for the Norwegian letter ‘æ’. The values may also be encoded, but this is not required.

Resolving locale

A locale is composed of language, country and variant. Language is required, country and variant are optional.

The string-representation of a locale is:

LA[_CO][_VA]

where

  • LA = two letter language-code
  • CO = two letter country-code
  • VA = two letter variant-code.

The variant argument is a vendor or browser-specific code. For example; WIN for Windows, MAC for Macintosh, and POSIX for POSIX. Where there are two variants, separate them with an underscore, and put the most important one first. For example, a Traditional Spanish collation might construct a locale with parameters for language, country and variant as: “es”, “ES”, “Traditional_WIN”.

When a localize function is called upon, a locale is resolved to decide which localization to use.

The following is considered, in this order:

  • Given as argument to function
  • Language specified on site

Finding best match

When localizing a keyword, a best match pattern will be applied to the resource bundle to select the localized phrase. If the locale for a request is resolved to “en-US”, these files will be considered in given order:

  • phrases_en_us.properties
  • phrases_en.properties
  • phrases.properties

If the locale for a request would have been resolved to en, the phrases_en_us.properties file would not have been considered when localizing a keyword.

If the locale does not match a specific file, the default phrases.properties will be used.

If no matching localization key is found in any of the files in a bundle, a default NOT_TRANSLATED will be displayed.

Storage

At the core of Enonic XP lies a distributed data storage with strong search-capabilities.

Overview

Years of experience has taught us that traditional approaches to data storage (read SQL) are unsuited for the common requirements of modern cloud-based applications and platforms. A key goal of Enonic XP was to deliver a complete stack - virtually eliminating complex dependencies to 3rd party applications, and minimize requirements to infrastructure.

With the growing popularity of various so-called NoSQL (Not Only SQL) solutions, we evaluated many different technologies and found great inspiration in the following:

Git
  • (+) Cherry picking
  • (+) Branching
  • (+) Pull requests
  • (-) Performance search
  • (-) Granularity of access (all or nothing)
Java Content Repository
  • (+) Hierarchy
  • (+) Granularity
  • (+) Feature set
  • (+) Unstructured
  • (-) Performance
  • (-) Complexity (not document oriented)
  • (-) Attached data model
  • (-) Requires additional storage backend
Elasticsearch
  • (+) Document oriented
  • (+) Scalability
  • (+) Performance
  • (+) Search
  • (+) Aggregations
  • (-) Search engine, not a database
  • (-) No blob support
  • (-) No security
  • (-) Creates schemas

We were unable to find any single solution that was sufficiently simple and included our desired feature set - so we decided to build our own; the Enonic Content Repository.

The Enonic Content Repository is a place where you can store data, or more specific, Nodes.

It is built on top of Elasticsearch and exposes many of it’s capabilities in search and aggregations and scalability - but in addition, provides the following capabilities:

  • Hierarchical storage model
  • Versioning support
  • Complete Access Control and security model
  • Blob support - using shared filesystem and append-only approach
  • Repository and Branch concepts for content staging
  • Schema-less - Add any property you like, at any time
  • Rich set of value types (Binary, Reference)
  • SQL-like query syntax

The Enonic Content Repository itself contains one or more separate repositories based on the application need. For instance, an application could demand a setup having three repositories - one for application data, one for users and one for logging:

_images/sub-repos.png

Repository

A repository is silo where nodes can be stored. Data stored in a repository will typically belong to a common domain. Fetches and searches are by default executed against a single repository, so it makes sense to keep data from different domains separated in different repositories.

When nodes are stored in the repository, two things happens:

  • The node properties are stored in a Blobstore as a node-version. A node-version is an entity representing the properties of the node, without name, parent and other meta-data.
  • The node is inserted into a Branches. The branch keeps track of a tree-structure referring to node-versions.
Built-in repositories

Out of the box, Enonic XP ships with two built-in repositories:

  • system-repo: The core repository. Here, users and groups, references to other repositories, installed application etc are stored.
  • cms-repo : Content domain data, this is the data managed in the Content Studio app.
Managing repositories

Repositories (including Branches) can be managed in the Repository API. When creating a repository, separate storage- and search-indexes will be created, and references to these repositories stored in the system-repo.

Branches

A branch is a set of data in a Repository. The data is organized hierarchically with path, unique in the branch. This means that the fully qualified location of a data object in Enonic XP consists of:

  • repo
  • branch
  • path

All repositories have a default branch called master. Any number of branches could be added to facilitate your data. E.g; in the content-repository, used for managing content in the Content Studio, there are two branches:

  • draft (data as seen in the Content Studio)
  • master (the data served in the portal)
Synchronizing branches

Often, you want to manage the same data-entities in different versions in different branches, and synchronize the data between them.

In the content-api, this operation is called to “publish” the data, which synchronizes the data between two branches. In the node-api, its also possible to get the diff between two repositories, and a push operation to push differences from one branch to another. These operations will ensure that references and dependencies are maintained, e.g its not possible to push a child-node to a branch if the parent does not exist in the target branch, so the parent node will also be pushed to the target branch.

Example:

Consider the ‘Oslo’ and ‘Enonic’ nodes from earlier sections:

_images/nodes.png

There will be two node-versions in the repository stored in the blobstore:

_images/node-versions.png

A node-version is a representation of a node’s properties. A node-version has no knowledge of name, parent or other meta-data: just the properties of a node. At the same time, the targeted branch (named ‘draft’ in this example) gets two entries:

_images/branch_initial.png

The node-versions are now a part of a tree-structure, based on the node’s name and parent. If we push the content of branch ‘draft’ to the default branch ‘master’, we end up with something like this:

_images/branch_push.png

At the moment, there are two branches pointing to the same node-versions. This means that a single node version can exist in several branches with different structures. Now, consider that the ‘oslo’ - node is updated and stored to the ‘draft’-branch, resulting in a new node-version with the same id and an updated pointer from the branch:

_images/branch_diff.png

The two branches now point to different node-versions of the ‘oslo’ node. Again, doing a push-operation from ‘draft’ to ‘master’ will result in both nodes pointing to the same node-versions:

_images/branch_push_2.png

Nodes

A Node represents a single storable entity of data. It can be compared to a “row” in sql, or a “document” in document oriented storage models. Nodes are, as mentioned in the previous section, stored in a repository.

Every node has:

  • a name
  • a parent-reference
  • an id
  • a timestamp
  • a (possibly empty) set of Property key/value.

Consider two nodes - one node representing the city “Oslo” and another representing the company, “Enonic”:

_images/nodes.png

The nodes have different properties. There is no schema to a node, so a node property value with the same property-name can have different value-types across nodes.

Property

Properties represent a placement of data in a node - following the simple key = value pattern. A property has a path. Elements in the path are separated by . (dot). Every property has also a type. See the complete list of Value Types.

myProperty
data.myProperty
cars.brands.skoda

For a property to be able to hold other properties, it has to be of type Set. In the above samples, data, cars and brands are properties of type Set.

Some characters are illegal in a property key. Here’s a list of illegal characters:

  • _ is illegal as the first character, because it is a reserved prefix for System Properties.
  • . is illegal as any character, since it is the path separator.
  • [ and ] are also illegal as any character. These are used as array index indicators.

Here’s an example of some properties:

first-name = "Thomas"
cities = ["Oslo", "San Francisco"]
city.location = geoPoint('37.785146,-122.39758')
person.age = 39
person.birth-date = localDate("1975-17-10")

Value Types

At the core of the node domain are value types. Every property to be stored in a node must have a value type. The value type enables the system to interpret and handle each piece of data specially - applying to both validation and indexing.

All value-types support arrays of values. All elements in an array must be of the same value-type.

Below is a complete list of all supported value-types.

String

A character string.

Index value-type

System Properties

To reduce complexity, we explicitly dropped the use of namespaces. Thus, in order to separate system properties from user defined properties, we reserved _ as a starting character for system properties.

Below are the system properties explained.

_childOrder
Default ordering of children when doing find children if no other order expression is given
_id
Holds the id of the node, typically generated automatically in the form of a UUID.
_indexConfig
Specification on how to index properties
_manualOrderValue
Numeric order value used for the builtin manual ordering
_name
Holds the name of the node. The name must be unique within its scope (all nodes with same parent).
_nodeType
Used to create collections for nodes in a repository.
_parentPath
Reference to parent node path.
_path
The path is resolved from the node name and parent path.
_permissions_read
The principals that have read access.
_permissions_create
The principals that have create access.
_permissions_delete
The principals that have delete access.
_permissions_modify
The principals that have modify access.
_permissions_publish
The principals that have publish access.
_permissions_readpermissions
The principals that have access to read the node permissions.
_permissions_writepermissions
The principals that have access to change the node permissions.
_state
Used for keeping state of a node in a branch.
_timestamp
The last change to the node version.
_versionKey
The id of the node version.

Blobstore

The blobstore is a file system location defaulted to $XP_HOME/repo/blob. The blobstore itself is split into one directory for nodes and one for binaries.

Admin

Go go backoffice!

Complex applications often require some kind of “back office” tools for management. Enonic XP provides a standardized approach to deliver and extend Admin tools.

This document describes how you can build your own Admin Tools and extend some of the default tools shipped with XP through Widgets.

Admin Tools

Warning

Admin Tool support is experimental.

Admin Tools are independent “back office” user interfaces designed to manage Enonic XP or installed applications. Each tool will run in it’s own browser tab - here are some of the reasons for this:

  • Faster user interfaces and better deep-linking support
  • Developers can use their favorite front-end frameworks
  • Simplified debugging

Standard Tools

Enonic XP is shipped with the following tools by default:

  • Home (The default tool)
  • Applications (Install, stop, start and uninstall applications)
  • Content Studio (Create and manage content and sites)
  • Users (Create, setup and manage users, groups and roles)

Launcher

Navigation between the various Admin Tools is done via the “Launcher Panel”, Accessible from the top right corner. This icon and the Launcher panel should be available across all Admin Tools.

_images/launcher.jpg

To create a new Admin Tool, you must create a new folder in your project structure, i.e. admin/tools/[tool-name]. Then you must place a descriptor, an icon and a controller there.

Descriptor

The tool descriptor defines the basic info to be displayed in the launcher and which roles are required to access the tool.

The descriptor file must have the same name as the tool, i.e. admin/tools/[tool-name]/[tool-name].xml:

<tool>
  <display-name>My Tool</display-name>
  <description>Control my stuff</description>
  <allow>
    <principal>role:system.admin</principal>
    <principal>role:myapp.myrole</principal>
  </allow>
</tool>
Icon

You should add an SVG icon to the tool. This will be displayed in the launcher panel together with the info from the descriptor. The icon file must have the same name as the tool, i.e. admin/tools/[tool-name]/[tool-name].svg:

Controller

To drive the tool, we will need a controller (See HTTP Controllers). The controller typically produces the initial tool html. Depending on the tool implementation it may also handle sub-requests from the tool.

The controller must have the same name as the tool, i.e. admin/tools/[tool-name]/[tool-name].js:

var mustache = require('/lib/xp/mustache');
var portalLib = require('/lib/xp/portal');
var timestamp = Date.now();

function handleGet() {
    var view = resolve('./my-view.html');

    var params = {
        adminUrl: portalLib.url({path: "/admin"}),
        assetsUri: portalLib.url({path: "/admin/assets/" + timestamp}),
        appId: app.name,
        appName: 'My custom tool'
    };
    return {
        contentType: 'text/html',
        body: mustache.render(view, params)
    };
}

exports.get = handleGet;
Adding the Launcher Panel menu

Adding the Launcher Panel menu to a custom admin tool requires two steps.

1. In the <body> section of the view add a Javascript snippet where you define an object variable called “CONFIG” with properties adminUrl, assetsUri and appId which will get their values from the controller:

<body>
    <!-- Configuration -->
    <script type="text/javascript">
    var CONFIG = {
        adminUrl: '{{adminUrl}}',
        assetsUri: '{{assetsUri}}',
        appId: '{{appId}}'
    };
    </script>
</body>
  1. Under the Javascript snippet add a reference to the Launcher’s Javascript file as shown below:
<body>
    <!-- Append the launcher -->
    <script type="text/javascript" src="{{assetsUri}}/apps/launcher/js/_all.js" async></script>
</body>

The entire view:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=Edge"/>
    <meta name="viewport" content="width=device-width, user-scalable=no">
    <meta name="theme-color" content="#ffffff">

    <title>{{appName}}</title>

    <!-- Styles -->
    <link rel="stylesheet" type="text/css" href="{{assetsUri}}/common/styles/_all.css">

    <!-- Common lib -->
    <script type="text/javascript" src="{{assetsUri}}/common/lib/_all.js"></script>

</head>
<body>

<!-- Configuration -->
<script type="text/javascript">
    var CONFIG = {
        adminUrl: '{{adminUrl}}',
        assetsUri: '{{assetsUri}}',
        appId: '{{appId}}'
    };
</script>

<!-- Append the Launcher Panel -->
<script type="text/javascript" src="{{assetsUri}}/apps/launcher/js/_all.js" async></script>

</body>
</html>

Widgets

Warning

Widget support is experimental.

Widgets are user interface components that can be used to extend various Admin Tools. Currently, the only available extension point for widgets are detail panels in the Content Studio tool.

To create a widget, you must create a new folder in your project structure, i.e. admin/widgets/[widget-name]. Then you must place a descriptor and a controller there.

Descriptor

The widget descriptor defines the display name, which roles are required to access the widget and the interfaces it matches.

An interface is simply a unique identifier that is used to create a link between a tool and the widget. For example, for your widget to be displayed in the “Content Studio” detail panel, add the interface “contentstudio.detailpanel”

The descriptor file must match the widget name, i.e. admin/widgets/[widget-name]/[widget-name].xml:

<widget>
  <display-name>My first widget</display-name>
  <interfaces>
    <interface>contentstudio.detailpanel</interface>
  </interfaces>
  <allow>
    <principal>role:system.admin</principal>
    <principal>role:myapp.myrole</principal>
  </allow>
</widget>
Controller

To drive the widget, we will need a controller (See HTTP Controllers). The controller typically produces the initial widget html. Depending on the widget implementation it may also handle sub-requests from the widget.

The controller file must match the widget name, i.e. admin/widgets/[widget-name]/[widget-name].js:

exports.get = function (req) {
    return {
        body: '<html><head></head><body><h1>My first widget</h1></body></html>',
        contentType: 'text/html'
    };
};

ID Providers

An ID Provider is a pluggable authentication module, contained inside an application. Install an existing ID Provider or write your own, configure it and associate it to a user store.

To create an ID provider, you must create a new folder in your project structure, i.e. idprovider. Then you must place a descriptor and a controller there.

Descriptor

The ID Provider descriptor is a required XML file used to define the mode and the configuration required by the provider. The descriptor file must have the following path: idprovider/idprovider.xml:

<id-provider>
  <mode>LOCAL</mode>
  <config>
    <input name="title" type="TextLine">
      <label>Title</label>
      <occurrences minimum="0" maximum="1"/>
      <default>User Login</default>
    </input>
  </config>
</id-provider>
mode

Specifies how the provider uses the user store.

LOCAL: Both the users and groups are stored locally in the user store.

EXTERNAL: Both the users and groups are stored in a remote system. The user store is only a snapshot view of this remote system and therefore the users and groups are not editable in the admin tool Users.

MIXED: The users are stored in a remote system and the groups in the user store. The users in the user store are only a snapshot view of this remote system and therefore the users are not editable in the admin tool Users.

config
Specifies the input fields of the configuration required by the ID provider.

Controller

The controller is a required file written in JavaScript and must have the following path: idprovider/idprovider.js:

var authLib = require('/lib/xp/auth');
var portalLib = require('/lib/xp/portal');

exports.handle401 = function (req) {
    var body = generateLoginPage();
    return {
        status: 401,
        contentType: 'text/html',
        body: body
    };
};

exports.login = function (req) {

    // If this function was called with a parameter "redirect", a validation of the origin is performed. 
    // The result of the validation is passed to the ID Provider as a request property "validTicket".
    var redirectUrl = req.validTicket ? req.params.redirect : undefined;

    var body = generateLoginPage(redirectUrl);
    return {
        contentType: 'text/html',
        body: body
    };
};

exports.logout = function (req) {

    // Calling "authLib.logout()" will log out the current user from Enonic XP.
    authLib.logout();

    // If this function was called with a parameter "redirect", a validation of the origin is performed. 
    // The result of the validation is passed to the ID Provider as a request property "validTicket".
    var redirectUrl = req.validTicket ? req.params.redirect : undefined;

    if (redirectUrl) {
        return {
            redirect: redirectUrl
        };
    } else {
        var body = generateLoginPage();
        return {
            contentType: 'text/html',
            body: body
        };
    }
};

exports.autoLogin = function (req) {
    log.info('Auto login. Invoked only when user is not authenticated');
};

function generateLoginPage(redirectUrl) {
    var authConfig = authLib.getIdProviderConfig();
    var title = authConfig.title || "User Login";
    var redirectionLink = redirectUrl ? '<a href="' + redirectUrl + '">Return</a>' : '';
    return '<html><head></head><body><h1>' + title + '</h1>' + redirectionLink + '</body></html>';
};
handle401
Optional function rendered in the case of a 401 error. This function typically produces a login or error page.
get/post/…
Functions rendered. An ID provider controller exports a method for each type of HTTP request that should be handled. The portal function idProviderUrl() will create a dynamic URL to this function.
login
Function rendered. The portal function loginUrl() will create a dynamic URL to this function.
logout
Function rendered. The portal function logoutUrl() will create a dynamic URL to this function.
autoLogin
Optional function executed if the current user is unauthenticated. This functions allows you to, for example, handle web tokens or other request headers.

Set up an ID Provider

To set up an ID Provider, you must follow the 3 steps below:

  1. An application containing an ID Provider must be installed and started (Use the admin tool Applications).
  2. The application must be associated to a user store and configured (Use the admin tool Users and edit the user store to guard).
  3. The user store must be associated to a virtual host in the virtual host configuration file (see Virtual Host Configuration).

Tasks

Tasks allow the asynchronous execution of jobs. Each task has a name, a JavaScript controller file, and an XML descriptor in the folder tasks/[task-name]

Descriptor

The task descriptor is an XML file that defines configuration parameters for the task.

When parameters are passed to the task controller, they will be validated according to the XML config schema (see Schemas).

The config element in the descriptor XML is optional. It can be left empty if the task does not take any parameters.

The descriptor file must have the same name as the task, i.e. tasks/[task-name]/[task-name].xml:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<task>
  <description>Background job</description>
  <config>
    <input type="Long" name="count">
      <label>Number of items to process</label>
      <default>42</default>
      <occurrences minimum="1" maximum="1"/>
    </input>
  </config>
</task>

Controller

A task controller handles the execution of the task. The controller is a required file written in JavaScript and must have the same name as the task, i.e. tasks/[task-name]/[task-name].js.

A task controller must export a run function, that will be called when the task is executed. The run function will receive the task parameters as a JSON object.

The following is an example of task controller.

var taskLib = require('/lib/xp/task');

exports.run = function (params) {

    var count = params.count || 42;

    taskLib.progress({info: 'Initializing task'});

    for (var i = 0; i < count; i++) {
        taskLib.progress({
            info: 'Processing item ' + (i + 1),
            current: i,
            total: count
        });

        processItem(i);
    }

    taskLib.progress({info: 'Task completed'});

};

Using Tasks

Tasks can be started by calling the submitNamed function in lib-task library.

Operations Guide

This guide gives you all the gory details on how to tune Enonic XP - if you’re looking for installation guides try Getting Started

_images/runs-anywhere.jpg

Package Structure

The unzipped Enonic XP distribution will have the following structure (folders with a * will not appear until the installation is started the first time)

enonic-xp-[version]
 |- bin/
 |- home/
   |- config/
   |- data/ *
   |- deploy/
   |- logs/
   |- repo/ *
   |- snapshots/
   |- work/ *
 |- lib/
 |- service/
 |- system/
 |- toolbox/
 |- work/ *

The root installation folder is referred to as XP_INSTALL. Here’s an explanation of all the other folders:

bin/
Contains the scripts for starting and stopping Enonic XP and setting environment variables.
home/

Home directory, also called XP_HOME. All files for a specific instance of XP reside here. This folder can be copied to other locations for working with multiple projects.

config/
Configuration files are placed here, including Virtual Host and system.properties.
data/
Additional data like exports and dumps. This folder will not appear until certain operations are run.
deploy/
Hot deploy directory. Applications are automatically installed upon placing their JAR files in this directory.
logs/
Default location for logs.
repo/
Repository data (blobs and indexes). This folder will not appear until the installation is started for the first time.
snapshots/
This is where snapshots are stored when using the snapshot-operation. This folder will not appear until a snapshot is done.
work/
Cache and generated bundles are stored here. This folder will not appear until the installation is started the first time.
lib/
Contains the bootstrap code used to launch Enonic XP.
service/
Contains install script for Linux to make Enonic XP run as a service. See: Install as service.
system/
System OSGi bundles are placed here.
toolbox/
Command-line interface tool to manage the server. See Toolbox CLI.
work/
OSGI cache is stored here. This folder will not appear until the installation is started for the first time.

Configuration

Enonic XP and 3rd party applications can easily be configured by editing the files in the $XP_HOME/config/ directory.

When changing files ending with .cfg, it’s respective application will automatically restart with the new configuration. Files ending with .properties require a full restart of Enonic XP to be applied. In a clustered environment, configuration files must be distributed to all nodes where it is relevant.

System Properties

The $XP_HOME/config/system.properties file must always be placed in this location. Any changes to this file will require a full restart of the node to take effect The standard version of this file is listed below.

$XP_HOME/config/system.properties
# Installation settings
# xp.name = demo

# Global security settings
# xp.suPassword = password

# Configuration FileMonitor properties
# felix.fileinstall.poll = 1000
# felix.fileinstall.noInitialDelay = true

# Config loading properties
# xp.config.paths = ${xp.home}/config

With Enonic XP versjon 6.9 a simple but powerful feature called “Config Paths” was introduced. In addition to the default $XP_HOME/config/ directory, you may now instruct XP to scan multiple different folders when looking for config files.

This provides great flexibility and can simplify configuration management. For instance:

  • Allowing selected users to manage application config, but not system configuration
  • Overriding standard config on selected nodes only

If multiple paths are listed, each directory will be scanned in the defined order, and the first file found of each configuration, will be used.

Below is an example usage of config path where it will scan three directories in the defined order.

xp.config.paths = ${xp.home}/config,/usr/local/xp/${node.group},/etc/xp/config

Please note that ${xp.home}/config is no longer required to be in the path.

Virtual Host Configuration

Virtual hosts have their own configuration file and settings are automatically updated upon changes. A sample virtual host configuration is listed below.

$XP_HOME/config/com.enonic.xp.web.vhost.cfg
enabled = true

mapping.test.host = localhost
mapping.test.source = /
mapping.test.target = /
mapping.test.userStore = system

mapping.intranet.host = enonic.com
mapping.intranet.source = /
mapping.intranet.target = /portal/master/enonic.com
mapping.intranet.userStore = enonic

mapping.admin.host = enonic.com
mapping.admin.source = /admin
mapping.admin.target = /admin
mapping.admin.userStore = system

In this example file, three mappings are configured.

host
Host-name to match.
source
Requested path to match.
target
Path to which the request is sent.
userStore
Key of the user store associated to this virtual host (see ID Providers).

In the second example, mapping “intranet”, a site is mapped to the root of the URL, which would be normal in production environments.

In the third example, the admin site is mapped to enonic.com/admin.

Mail Configuration

The mail server used for sending email messages can be configured. A sample mail configuration is listed below.

$XP_HOME/config/com.enonic.xp.mail.cfg
smtpHost=mail.server.com
smtpPort=25
smtpAuth=true
smtpUser=user
smtpPassword=secret
smtpTLS=false
smtpHost
Host name of the SMTP server. Default localhost.
smtpPort
TCP port of the SMTP server. Default 25.
smtpAuth
Enable authentication with the SMTP server. Default false.
smtpUser
User to be used during authentication with the SMTP server, if ‘smtpAuth’ is set to true.
smtpPassword
Password to be used during authentication with the SMTP server, if ‘smtpAuth’ is set to true.
smtpTLS
Turn on Transport Layer Security (TLS) security for SMTP servers that require it. Default false.

Repo Configuration

snapshots.dir
Where to store snapshots
$XP_HOME/config/com.enonic.xp.repo.cfg
#
# Where to store snapshots.
#
snapshots.dir = ${xp.home}/snapshots

Storage Configuration

Blobstore Configuration

Main blobstore configuration is configured in com.enonic.xp.blobstore.cfg.

$XP_HOME/config/com.enonic.xp.blobstore.cfg
provider = file
cache = true
cache.sizeThreshold = 1mb
cache.memoryCapacity = 100mb
provider
The blobstore provider to be used for storing. Default value is file. Other providers will be available in future versions / enterprise-edition. Each provider will have a separate configuration file named com.enonic.xp.blobstore.<providername>.cfg
cache
Enable or disable memory caching of blobs fetched from the blobstore. Default true
cache.sizeThreshold
The maximum size for objects to be cached, defaults to 1MB. You will usually avoid filling up the cache with large blobs, but rather cache smaller objects that are used often. The size notation accepts a number plus byte-size idenfier (b/kb/mb/gb/tb/pb)
cache.memoryCapacity
The maximum memory footprint of the blob cache. Defaults to 100MB. The size notation accepts a number plus byte-size idenfier (b/kb/mb/gb/tb/pb)

readThrough.enabled = false
Enable or disable readthough provider usage. Default to false.
readThrough.sizeThreshold = 100mb
The maximum size for objects to be stored in the readthrough provider, defaults to 100MB. The size notation accepts a number plus byte-size idenfier (b/kb/mb/gb/tb/pb)

The market-place for installing applications can be configured using the com.enonic.xp.market.cfg file

$XP_HOME/config/com.enonic.xp.market.cfg
marketUrl = https://market.enonic.com/applications

UDC Configuration

UDC (Usage Data Collector) is collecting anonymous usage data 10 minutes after startup and every 24 hours. It is only used for finding out what platforms to focus on and improve platform stability. To switch this off, you can configure it sing the com.enonic.xp.server.udc.cfg file

$XP_HOME/config/com.enonic.xp.server.udc.cfg
#
# Set to false to disable usage data collector (UDC)
#
enabled = true

Cluster Deployment

Introduction

Consider deploying an XP cluster if you are building applications or sites that require

  • High availability
  • High performance
  • Both above

A clustered deployment of Enonic XP enables you to distribute load across servers (aka nodes) and at the same time increased resilience. If one node fails the rest of the cluster will still be running and keep your services available.

Ways to Cluster

The minimal and simplest cluster deployment is three nodes - identically configured. However There are many available configurations when deploying a cluster, here are some factors to consider

  • Dedicated nodes for specific sites or services
  • Dedicated admin nodes
  • Dedicated storage nodes
  • Dedicated master nodes

Attention

Clusters with a paired number of nodes should be avoided due to the so-called split-brain scenario - discussed further below.

System Requirements

Enonic XP clusters have minimal requirements to infrastructure, it needs:

  • Distributed (or shared) filesystem
  • Load balancer - to make sure traffic is routed to different nodes
_images/logical-cluster.png

These components are standard ingredients in modern clouds and they are readily available as software as well. An XP cluster can also be launched on a single computer for testing or development purposes.

Basic cluster setup on local machine

We have strived to make Enonic XP deployment as simple and fail-safe as possible. By default it is configured to run on a local computer and it will not start looking for nodes in the network until you configure it to do so.

To test a cluster on your local machine, you need to do the following:

  1. Get two XP installations: Download an $XP_DISTRO and copy it to a second $XP_DISTRO folder.

Typically, you will already have an XP-installation by now, so just copy the $XP_DISTRO folder to make another node.

  1. Share data: Prepare a common place for storing data and configure both XP instances:

In $XP_DISTRO/home/config/com.enonic.xp.blobstore.file.cfg set the following property to point to a common directory:

baseDir = /some/common/path
  1. Give each node its own HTTP-port: Since you will run two nodes on the same machine, you also need to set two different HTTP-ports to be able to run two instances at once:

In $XP_DISTRO/home/config/com.enonic.xp.web.jetty.cfg set the following property to different values for the two nodes, typically 8080 and 8090

http.port = somePort
  1. Enable clustering: In $XP_DISTRO/home/config/com.enonic.xp.elasticsearch.cfg set the property node.local to false
node.local = false
  1. Start your cluster: Start both nodes by their respective bin/server.sh or bin\server.bat. They will connect and you should have a live cluster on your machine. You can check the current cluster info at:
http://localhost:8080/status/cluster

Note

By default, if no XP_HOME environment variable is set, the XP_HOME used is the one located in the XP_DISTRO/home folder which will work nicely for the above example. If you have set XP_HOME in the shell where you try to start the server, this will override the default settings. So for the above test, unset the XP_HOME variable if needed:

unset XP_HOME

Cluster configuration

There are a well of options at your disposal to configure and tune the cluster behavior. See Elasticsearch configuration for a subset of the available settings. All settings referred to in this chapter are set in $XP_HOME/config/com.enonic.xp.elasticsearch.cfg unless otherwise specified.

There are some key elements to consider when setting up a cluster:

  1. Set up a shared storage for the nodes -> Shared storage Configuration
  2. Make sure that nodes are connected -> Network configuration
  3. Distribute the data between the nodes -> Replica setup
  4. Ensure cluster data integrity -> Cluster partition settings
  5. Ensure cluster stability -> Cluster stability settings
  6. Make sure nodes recover correctly -> Node recovery settings
  7. Monitoring the cluster -> Cluster monitoring
  8. Deploying applications -> Deploying Apps in cluster
  9. Securing data -> Backing up a cluster

Shared storage Configuration

For now, the nodes in the cluster need a shared storage to store data as files. Setting this up is highly individual for different operating systems and infrastructures, but as a basic guideline:

  1. Get access to a shared or distributed file system and mount it on the nodes that will be part of the cluster
  2. Configure $XP_HOME/config/com.enonic.xp.blobstore.file.cfg to point to the mounted storage:
baseDir = /path/to/shared/disk/folder

Network configuration

The nodes in a cluster need to be able to discover and communicate with other nodes in the network. The nodes communicate through TCP.

Each node binds to an IP-address and port, and communicates to other nodes specified in a list of other nodes bind addresses. Verify that your network allows TCP traffic on a specific port or port-range for the nodes to communicate and then configure the nodes to use these addresses.

Settings
node.local

When this setting is true, the node will never try to join a cluster. In all cluster setups, nodes must set this to false

network.host

The network.host setting specifies the TCP-address used for node communication. The default value for this is 127.0.0.1, which means that this node will never be able to talk to other nodes.

The network.host setting can be an explicit IP-address, a host-name or an alias. See the Elasticsearch configuration section for an overview.

transport.tcp.port

The transport.tcp.port value defines the port that the node will use for communication. This defaults to a range of ports; 9300-9400, meaning that it will use the first available port in this range.

discovery.zen.ping.unicast.hosts

The discovery.zen.ping.unicast.hosts value contains a comma-separated list of nodes that are allowed to join the cluster. Each value is either in the form of host:port or host:port1-port2 (port-range).

Sample config
transport.tcp.port = 9300-9400
network.host = _eth0:ipv4_ 
discovery.zen.ping.unicast.hosts = 10.0.6.47[9300-9400],10.0.6.49[9300-9400],10.0.6.73[9300-9400],10.0.6.74[9300]

Tip

Why aren’t my nodes connecting

The most common issue is that the node binds to a different network address than specified in the unicast list. When a node starts, the log will show the current bind-address of the node in a message similar to this:

09:01:43.282 INFO  org.elasticsearch.http - [loadtest-appserver1] bound_address {inet[/10.0.6.49:9300]}, publish_address {inet[/10.0.6.49:9300]}

Make sure that the bind-addresses match those specified in the unicast-list. If it still doesn’t work, it’s time to blame the firewall or consult the Troubleshooting

Replica setup

Number of replicas

For a cluster to perform, each node must be able to do its share of work. Enonic XP searches for data in a number of Elasticsearch indices. An index can have a number of replicas (copies) spread around to the nodes in the cluster, so each node can query its local index for data.

The indices in Enonic XP have one replica configured by default. When a cluster has more than two nodes, this number must be increased to ensure that each node has a replica of the indices.

The number of replicas can be set at runtime with the Toolbox CLI set-replicas, and the recommended settings for replicas is number of nodes - 1

So for a 3 node cluster, the number of replicas should be set to 2.

Cluster partition settings

One of the main motivations of a cluster is to ensure that even if one or several nodes fail, the service you are providing should still be available. In an ideal world, a 100 node cluster should be fully operational even if 99 nodes are down. But in the real world, we also need to consider the cluster data integrity. This introduces a common dilemma in clustered environments; how to avoid the dreaded split-brain situation.

In a split-brain scenario, nodes get divided into smaller clusters that don’t communicate with each other, and each cluster believing that the nodes in the other cluster are dead. This can easily happen in a cluster with 4 nodes on two different locations:

If the nodes on location-1 are disconnected from the master node on location-2, they will regroup and select a new master on location-1 and still provide service. The nodes on location-2 will assume that the nodes in location-1 are dead, so they will also continue serving requests. but they have no way of synchronizing data between the locations. This will break the integrity of the cluster and make data invalid.

To avoid this situation, there are a couple of basic properties of a cluster that should be ensured:

  1. Beyond a two node cluster, there should be an odd number of nodes. So 1,2,3,5,7 etc are all acceptable cluster configurations.
  2. When nodes are forming separate smaller clusters, only the cluster-partition with the majority of nodes should be fully operational and accept writes.
  3. The minority cluster partitions can be allowed to serve read-only requests if that is acceptable for the provided service.
Settings
discovery.zen.minimum_master_nodes

This is the most important setting to set correctly to ensure cluster data integrity. A node will not accept requests before the number of ‘minimum_master_nodes’ are met. For instance, in a 3 node cluster with 3 master nodes and ‘minimum_master_nodes’ setting of ‘2’, imagine that one of the nodes loose connection to the two other nodes. This node will only see one possible master node (itself) and will not accept requests. The remaining two other nodes will still work, and when the lost node reconnects again, it will get the fresh data from the other nodes and rejoin the cluster.

Important

As a rule of thumb, this setting should be set to N/2+1, where N is the total number of nodes. So for a 5 node cluster, discovery.zen.minimum_master_nodes = 5/2+1 = 3 (rounding down to the nearest integer)

So what about a 2 node cluster? It will be impossible to avoid a possible split-brain scenario with this setup. It’s highly recommended to add one node as a tie-breaker. This node may act as a dedicated master node (with node.data = false, see Cluster stability settings) which enables it to run on reduced hardware since it will not handle any external requests.

A common practice for increased stability is setting up dedicated master nodes. These nodes will then never be affected by traffic peaks and can safely keep track of the cluster state.

Tip

Why nodes leave the cluster

There are 2 main reasons why cluster nodes leave the cluster

  1. Network failure
  2. Node not responding

Network failures

Network failures are the main reason for cluster stability-issues. The problems could have any number of reasons, from a router breaking down to complex scenarios where e.g a firewall cuts the connection in one direction between two nodes

Node not responding

If a node does not get a response on a ping to the master node within a set timeout, it will consider it as dead and invoke an election process. Likewise, the master node expects that a slave node will respond within a certain amount of time. This is usually caused by a node doing a stop-the-world garbage collection, and not being able to respond to the request at all for a period of time.

Cluster stability settings

In a low load environment, there is probably no need to do a lot of tuning since it will perform acceptable with the default setup. If you expect heavy load, there are a couple of things to consider when setting up the cluster topology.

Dedicated master nodes

A cluster consists of a number of nodes sharing data and state between them. A cluster needs to have exactly one node acting as a master-node at any time. The master-node is responsible for managing the cluster-state. In a busy cluster, the master-nodes will have to do a lot of work to ensure that all other nodes get the needed information.

Since the cluster stability depends on a healthy master node, it may be a good idea to set aside a number of nodes as dedicated master nodes. These dedicated master nodes should not be handling external requests, but rather concentrate on keeping the cluster nodes in sync and stable.

A node can be configured to be allowed to act as a master-node by the setting node.master.

A dedicated master node should have the following settings:

node.master = true
node.data = false
Data nodes

Data nodes are the workhorses of the cluster. They will handle the bulk load of the requests, depending on the master node to keep them in sync. These nodes need the most memory and CPU power.

A dedicated data node should have the following settings:

node.master = false
node.data = true

Node recovery settings

Node recovery happens when a node starts or reconnects to the cluster after a e.g a network shortage.

Consider a cluster of 2 nodes. When a node starts for the first time, it will try to connect to a cluster. If no master found, it will elect itself as master, then proceed to initialize the index-data locally. If it does find an existing master node, it will require the master to provide it with data. This is all good, but there may occur situations where a new node in an existing cluster starts initializing data before the nodes with existing data can inform the new node that there is already data in the cluster.

Settings
gateway.recover_after_nodes

Defaults to 1. Do not start the recovery of local indices before this number of nodes (master or data) has joined the cluster.

gateway.recover_after_master_nodes

Defaults to 0. Do not start the recovery of local indices before this number of master-nodes is present in the cluster.

Cluster monitoring

See Cluster monitoring

Deploying Apps in cluster

To deploy applications in a cluster you need to deploy the application to every node, as loading and installation of apps is done on a per-node basis. This also means you can choose what applications to deploy on each node.

Warning

Remember that XP only supports running one version of an application at any time. So don’t leave the old versions of your applications in the deploy directory.

Backing up a cluster

Backing up a cluster is done in the same way as backing up a single node installation, the only difference is that the snapshots.dir-option should point to a shared file system location, see Storage Configuration.

  1. First, on any cluster node, take a :toolbox-snapshot of the indices. This will store a cluster-wide snapshot of all data at a point of time. This can be configured to run as an automatic job; Only the diff from the last snapshot will be stored, so the operation is quick.
  2. Second, take a file copy of your blobstore.

We recommend uisng incremental backup for the blobstore (rsync or similar) as this will only copy the recently changed files. The combined data from the snapshots and blobstore copy is all you need in order to restore Enonic XP.

Reverse Proxy Servers

A common and recommended way to deploy Enonic XP is by using reverse proxy servers. Adding this layer of services to your network provides additional flexibility beyond what is offered directly by XP. Some potential benefits are:

  • Vhost routing to XP and other systems
  • Additional network security
  • Certificate and HTTPS handling
  • URL rewriting
  • Load balancing
  • Resource caching
  • Logging
  • and more

Below we describe how to configure popular web servers as proxies in front of a single Enonic XP node.

Apache

Attention

Prerequisites
  • Apache 2.4 downloaded and running on local machine
  • Enonic XP downloaded and started on local machine, using the default port 8080

Apache provides a detailed tutorial on setting up proxies here: http://httpd.apache.org/docs/2.4/howto/reverse_proxy.html

Load Mod Proxy

To get started we need to add some selected Apache Proxy Modules.

Add the following line after the other LoadModule directives in your Apache configuration aka httpd.conf

LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so
LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so
LoadModule proxy_wstunnel_module /usr/lib/apache2/modules/mod_proxy_wstunnel.so
Setup Apache Vhost
Apache Vhost with Proxy config
<VirtualHost *:443>

    ServerName mydomain.com
    DocumentRoot /var/www/html/

    ProxyRequests Off
    ProxyPreserveHost On

    ProxyPass /admin/event ws://localhost:8080/admin/event
    ProxyPassReverse /admin/event ws://localhost:8080/admin/event

    ProxyPass / http://localhost:8080/
    ProxyPassReverse / http://localhost:8080/

</VirtualHost>

This setup will proxy all requests directly through Apache to XP, also notice the WebSocket directive. Enonic XP admin UI uses websockets actively, as this is not http traffic, a separate proxy needs to be configured.

Nginx

Work in progress

Monitoring

We provide some basic metric tools for monitoring which are easily accessed in a simple JSON format. To access the monitoring JSON feed you can point to the following url:

http://localhost:8080/status

This will give you a list of status-reporters. Each reporter has a name and can be accessed using the following pattern:

http://localhost:8080/status/<name>

Here’s a list of all the status pages and what is shows:

cluster
Information of the current cluster. Local-node and members.
dump.deadlocks
This will try to detect thread deadlocks and show them if any.
dump.threads
Dumps all current thread-states.
index
Shows ElasticSearch index status.
jvm.gc
Information about JVM GC status.
jvm.info
General JVM information (version, vendor, uptime).
jvm.memory
JVM memory information (heap and non-heap).
jvm.os
Information about OS (name, version, architecture).
jvm.properties
Shows all JVM properties.
jvm.threads
JVM thread stats (count, peak, total).
metrics
Shows metrics. The information can be filtered using ?filter=....
osgi.bundle
Information about all OSGi bundles.
osgi.component
Information about registered SCR OSGi components.
osgi.service
Shows all OSGi services registered.
server
Information about the server (version, build).

Cluster monitoring

There are two tools at your disposal for monitoring the health of the cluster and indices:

Cluster health
http://<host>:<port>/status/cluster

Which should give you a response like this:

{
    "localNode": {
        "hostName": "Runars-MacBook-Pro.local",
        "id": "xUfgZ2FdRu6q-CLJA4CIkA",
        "isMaster": true,
        "numberOfNodesSeen": 2,
        "version": "1.4.4"
    },
    "members": [
        {
            "address": "inet[/127.0.0.1:9300]",
            "hostName": "Runars-MacBook-Pro.local",
            "id": "xUfgZ2FdRu6q-CLJA4CIkA",
            "isMaster": true,
            "version": "1.4.4"
        },
        {
            "address": "inet[/127.0.0.1:9301]",
            "hostName": "Runars-MacBook-Pro.local",
            "id": "yvHpvM7KQn6y6yTZ-QIRNw",
            "isMaster": false,
            "version": "1.4.4"
        }
    ],
    "name": "mycluster",
    "state": "YELLOW"
}

This view gives a brief overview of the nodes in the cluster. For convenience, the current local node to which the request was made has a separate entry in addition to being in the list of members.

The “state” property is the most important:

  • Green: Cluster is operational and all configured replicas are distributed to a node
  • Yellow: Cluster is operational, but there are replicas that are not distributed to any node
  • Red: Cluster is not operational

To see the details about how the replicas are distributed, let’s continue to the Index stats report:

Index stats
http://<host>:<port>/status/index

Which should give you a response like this:

{
    "summary": {
        "total": 8,
        "started": 4,
        "unassigned": 4
        "initializing": 0,
        "relocating": 0,
     },
    "shards": {
        "initializing": [],
        "relocating": [],
        "started": [
            {
                "id": "search-cms-repo(0)",
                "nodeAddress": "10.0.6.146",
                "nodeId": "xUfgZ2FdRu6q-CLJA4CIkA",
                "type": "PRIMARY"
            },
            {
                "id": "search-system-repo(0)",
                "nodeAddress": "10.0.6.146",
                "nodeId": "xUfgZ2FdRu6q-CLJA4CIkA",
                "type": "PRIMARY"
            },
            {
                "id": "storage-system-repo(0)",
                "nodeAddress": "10.0.6.146",
                "nodeId": "xUfgZ2FdRu6q-CLJA4CIkA",
                "type": "PRIMARY"
            },
            {
                "id": "storage-cms-repo(0)",
                "nodeAddress": "10.0.6.146",
                "nodeId": "xUfgZ2FdRu6q-CLJA4CIkA",
                "type": "PRIMARY"
            }
        ],
        "unassigned": [
            {
                "id": "search-cms-repo(0)",
                "nodeAddress": "UNKNOWN",
                "type": "REPLICA"
            },
            {
                "id": "search-system-repo(0)",
                "nodeAddress": "UNKNOWN",
                "type": "REPLICA"
            },
            {
                "id": "storage-system-repo(0)",
                "nodeAddress": "UNKNOWN",
                "type": "REPLICA"
            },
            {
                "id": "storage-cms-repo(0)",
                "nodeAddress": "UNKNOWN",
                "type": "REPLICA"
            }
        ]
    }
}

This gives an overview of how the indices are distributed and what state the index parts (shards) are currently in. A shard could be either PRIMARY or REPLICA (copy of a primary shard). These are the possible states:

  • total: Total number of index parts (e.g two repositories with two indices with one replica for each index)
  • started: Shards that are currently assigned to a node
  • unassigned: Shards waiting to be distributed to a node. Typically a setup with a number of replicas where one or more nodes are not running
  • relocating: Shards that are currently moving from one node to another
  • initializing Shards that are currently being recovered from disk at startup.

The shards section gives a more detailed overview on the shard distribution.

Install as service

When installing Enonic XP on a standard production server, you will want to set it up to run as a service.

First, make sure the correct version of Java is installed on your system. See Install Java for guidance.

Linux

Install with script

Attention

The script is written for and tested on Ubuntu / CentOS. For other distrubutions, the manual installation may be neccessary.

Prerequisites
  • User with sudo rights
  • Java JRE 1.8+ installed
  • /lib/lsb/init-functions installed
  1. Download the Enonic XP distribution
  2. Unzip the distributiopn
  3. Run script: sudo ./enonic-xp-6.12.3/service/install_service.sh
  4. Optional: Set JAVA_HOME and JAVA_OPTS variables in /etc/xp.conf
  5. Start service: sudo service xp start
  6. Check log: sudo tail -f /home/xp/enonic/xp/logs/server.log
Manual installation

See Linux install as service detailed

Windows

Info on running XP as a service in windows will come later.

Backup and Restore

Backing up your data is vital for any installation.

All the data in an Enonic XP installation is stored in $XP_HOME/repo. This directory has two folders: blob and index.

The blob folder contains all files needed by the system to manage your data, while the index folder contains the Elasticsearch index folders. These are dependent on each other in the sense that one is not much use without the other.

That leaves us with ensuring that two elements are safely stored for retrieval in an emergency:

  • $XP_HOME/repo/blobs
  • $XP_HOME/repo/index

Backup vs Export

The export/import enables you to export your data to a serialized format. The serialized data could then be imported into another instance. This is very useful, but is not optimal for a backup/restore scheme since it requires some work to get things up and running again, especially when working with big installations with a lot of data. The backup/restore-process described below on the other hand, should enable a quick and safe way to get your system back to operation when in a hurry.

See Export and Import for more information on export/import.

Backing up blobs

The blobs are just files on a filesystem. This should be backed up by your preferred way of doing file-backups.

The folder to backup is:

  • $XP_HOME/repo/blobs

Backing up indexes

Backing up the indices is a bit more complex than just copying the index-folder since it involves floating data with state, especially in a clustered environment. To help you out, we have a snapshot-API. A snapshot is exactly that; a snapshot of the indices state at a point of time. There are 4 rest-resources at your disposal.

http://<your-installation>/admin/rest/repo/snapshot
Stores a snapshot of the current indices state.
http://<your-installation>/admin/rest/repo/list
Returns a list of available snapshots for the installation.
http://<your-installation>/admin/rest/repo/restore
Restore a snapshot of the indices state.
http://<your-installation>/admin/rest/repo/delete
Deletes a snapshot or a group of snapshots.
Snapshot

The snapshot rest-service accepts a JSON in this format:

{
  "repositoryId": "<repository-id>"
}

A snapshot of the given repository will be created for later retrieval. Each subsequent snapshot will store the changes between this snapshot and the last snapshot of the given repository. This means that only changed data are stored when doing subsequent snapshots. The default location where snapshots are stored is $xp_home/snapshots. A name of the snapshot will be given at snapshot-time, and returned in the snapshot-result.

To ease the process, we have provided a snapshot tool.

Restore

The restore rest-service accepts a JSON in this format:

{
  "snapshotName": "<snapshot-name>",
  "repository" : "<repository-id>"
}

The indices will be closed for the duration of a restore operation, meaning that no request will be accepted while the restore in running. To ease the process, we have provided a restore tool.

Warning

Restoring a snapshot will restore data to the exact state of the indices at the snapshot-time, meaning all other changes will be lost.

Delete

The delete rest-service accepts a JSON in this format:

{
  "snapshotNames": ["name1", "name2"],
  "before" : "<timestamp>"
}

Deletes either all snapshots before timestamp, or given snapshots by name. To ease the process, we have provided a delete-snapshots tool.

Export and Import

Exporting and importing data in your Enonic XP installation is useful both for securing data and migrating between installations. Enonic XP ships with a set of tools (Toolbox CLI) to ease the operation of exporting and importing data from the system.

Caution

At the moment, exporting and importing data can only be done to and from files on the same server running Enonic XP.

Content Export/Import vs System Dump/Load

Both enable you to export your data to a serialized format and import the serialized data into another instance. But, while the export/import focuses on a given content, the dump/load is used to export an entire system (all repositories and branches). This is used, for example to migrate between systems or perform upgrade scripts. Dump and Load also supports dumping complete version history and branches.

Content Export

The export operation will extract data for a given content URL and store it as XML in a sub-folder under $XP_HOME/data/export. The REST service for export is found at the following URL:

http://<host>:<port>/api/repo/export

The export REST service accepts a JSON in this format:

{
  "sourceRepoPath": "<source-repo-path>",
  "exportName": "<name>",
  "exportWithIds": <true|false>,
  "dryRun": <true|false>
}

To ease the process, we have provided an export tool.

Content Import

The import will take data from a given export directory and load it into Enonic XP at the desired content path. The REST service for import is found at the following URL:

http://<host>:<port>/api/repo/import

The import REST service accepts a JSON in this format:

{
  "exportName": "<name>",
  "targetRepoPath": "<target-repo-path>",
  "importWithIds": <true|false>,
  "importWithPermissions": <true|false>,
  "dryRun": <true|false>
  "xslSource": "<xsl-file-path>"
  "xslParams": {
    "<name>": "<value>"
  }
}

To ease the process, we have provided an import tool.

Content Export data structure

Let’s look at how this works. The following structure will be exported:

_images/export-source.png

Run the export command:

$ ./toolbox.sh export -a su:password -s cms-repo:draft:/ -t myExport

Below is the resulting structure in the export folder $XP_HOME/data/export/myExport:

./content
./content/_
./content/_/node.xml
./content/demo-site
./content/demo-site/_
./content/demo-site/_/manualChildOrder.txt
./content/demo-site/_/node.xml
./content/demo-site/_templates
...
./content/demo-site/case-studies
./content/demo-site/case-studies/_
./content/demo-site/case-studies/_/node.xml
./content/demo-site/case-studies/a-demo-case-study
...
./content/demo-site/case-studies/a-demo-case-study/enonic man.png
./content/demo-site/case-studies/a-demo-case-study/enonic man.png/_
./content/demo-site/case-studies/a-demo-case-study/enonic man.png/_/bin
./content/demo-site/case-studies/a-demo-case-study/enonic man.png/_/bin/Enonic man.png
...
./content/demo-site/case-studies/powered-by-sites
...
./content/demo-site/contact-enonic
...
content
The base folder of the export. All content in cms-repo has this as root path.
content/_
All folders named _ are system folders for the data at the current level.
content/_/node.xml
The definition of the node, e.g. all data for the current node
content/demo-site
This is the site from the screenshot above.
content/demo-site/_/manualChildOrder.txt
Our demo-site has manually ordered children, this file contains an ordered list of children.
content/demo-site/case-studies
This ‘case-studies’ content is the first element in the site.
content/demo-site/case-studies/a-demo-case-study/enonic man.png/_/bin
The A demo case study content has a binary attachment called Enonic man.png. The folder _/bin contains the actual binary files.

Changing export data

It is possible to make manual changes to the exported data before importing.

Using the above export as an example, the demo-site displayName can be changed to something more suitable:

myExport $ vi content/demo-site/_/node.xml

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<node xmlns="urn:enonic:xp:export:1.0">
  <id>2dfbdc41-af98-4b3c-a2a9-9dc4814d003a</id>
  <childOrder>_manualordervalue DESC</childOrder>
  <nodeType>content</nodeType>
  <data>
    <boolean name="valid">true</boolean>
    <string name="displayName">My much nicer demo-site!</string>
    <string name="type">portal:site</string>
    <string name="owner">user:system:su</string>

After some data has been changed, it can be imported again:

$ ./toolbox.sh import -a su:password -s myExport -t cms-repo:draft:/
_images/import-result.png

Caution

Editing exported data is experimental at the moment and will potentially cause trouble if not done carefully. For exports without ids, references will be broken and must be fixed manually. When importing with ids onto existing data, renaming and changing manual order will not yet work as expected.

System Dump

The dump operation will extract data from your entire system and store it as XML in a sub-folder under $XP_HOME/data/dump. The REST service for export is found at the following URL:

http://<host>:<port>/api/system/dump

The dump REST service accepts a JSON in this format:

{
  "name": "<dump-name>"
}

To ease the process, we have provided a dump tool.

System Load

The load operation will take data from a given dump directory and load it into Enonic XP. The REST service for load is found at the following URL:

http://<host>:<port>/api/system/load

The export REST service accepts a JSON in this format:

{
  "name": "<dump-name>"
}

To ease the process, we have provided a load tool.

Troubleshooting

This document is an up-to-date list of known problems (and how to fix them) for our current release and development releases.

Wrong Java version

Verify that Java 1.8 (update 92 or higher) is installed and that this version is actually used.

Run java -version in the shell where you attempt to start Enonic XP:

$ java -version
java version "1.8.0_92"
Java(TM) SE Runtime Environment (build 1.8.0_92-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)

The boot log will also output the version of Java that was actually used.

If the Java version does not match your expected version, make sure that the JAVA_HOME environment variable is set correctly. For OS X and Linux users - execute the following in your command line:

export JAVA_HOME=`/usr/libexec/java_home -v 1.8`

Optionally add the line to your ~/.properties file to make the change persistent.

Check the Troubleshooting Java page for more Java help.

Port 8080 already taken

A lot of different web software defaults to port 8080. If you find that the log is complaining about this, simply identify the other software you have running on this port and stop it.

If shutting down other software that uses port 8080 is not an option, you may set a different port for Enonic XP. See Configuration.

Unexpected behavior

While frequently redeploying an app during development, some instability or unexpected behavior may be noticed. This can be caused by certain changes to the app files. For example, changing the app name in the build.gradle file, or deleting content import node.xml files. When this occurs, the project may need a clean build gradle clean build. Sometimes the app JAR file may need to be deleted from the $XP_HOME/deploy directory as well, and then replaced with the clean build JAR file.

Having two versions of the same app in the $XP_HOME/deploy folder will cause problems.

Cannot login after install

There could be a problem with file permissions on Windows if Enonic XP was unzipped and started from within the “My Documents” folder. This may allow XP to start, but the users cannot log in. The solution would be to unzip the Enonic XP distribution outside of the “My Documents” folder, or to manually change the file permissions.

Sending email with lib-mail not working

Check the installation’s Mail Configuration.

Troubleshooting Java

Important

This documentation is based on OSX, Windows version coming later..

Check current JDK version

To see all installed JDK’s on you environment, if any, type the following command in your terminal:

~/ $ /usr/libexec/java_home -V
Matching Java Virtual Machines (4):
    1.8.0_45, x86_64:  "Java SE 8"     /Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home
    1.8.0_40, x86_64:  "Java SE 8"     /Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home
    1.8.0_20, x86_64:  "Java SE 8"     /Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home
    1.7.0_67, x86_64:  "Java SE 7"     /Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home
~/ $

If you have a JDK equal to or above version 1.8.0_92, but the javac -version points to another version, proceed to set the JAVA_HOME environment variable correctly.

Setting JAVA_HOME

If you don’t have a JDK equal to or above version 1.8.0_92, you must install a newer version.

  • Go to the JDK page and click the “JDK download” button. This button will always link to the latest version.
  • Follow the installation instructions.
  • After installation, proceed to check that the JAVA_HOME environment variable is set correctly.

To check the current JAVA_HOME environment variable:

~/ $ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home
~/ $

If this is not set correctly, you must set the correct one either for this terminal session, or in your .profile or .bashrc for all terminal sessions.

  • To set the correct JAVA_HOME for the current terminal session; invoke the following command in your terminal. This command will set JAVA_HOME to the newest installed 1.8 JDK-version:
~/ $ export JAVA_HOME=`/usr/libexec/java_home -v 1.8`
  • To set for all terminal sessions, add the entry to either your ~/.bash_profile or ~/.profile.
$ vim .bash_profile

export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)

$ source .bash_profile

$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/1.8.0_45.jdk/Contents/Home

Content Studio

The Content Studio is the Web CMS interface of Enonic XP. It is used for managing and publishing content. It also provides the tools for building and extending web applications from the components of the installed apps.

Opening the Content Studio reveals the Browse View with a menu bar, content tree grid, preview panel and details panel. The Edit view appears when content is created or edited and will open in a new browser tab. All actions and features will be described in the following pages.

Hint

The Content Studio is fully responsive, so panels may stack or collapse if the screen is small or narrow. This documentation will assume a large desktop view.

_images/content-studio.jpg

Browse View

The Browse view is the default page of the Content Studio. It consists of a menu bar on top and two or three panels below it. On the left is the Content tree grid where all the sites and content can be found. To the right of the tree grid is the Preview panel which displays a preview of the selected content. On the far right is the Detail panel that may be toggled on and off with the detailicon icon in the top right corner.

_images/content-studio.png
Toolbar

The toolbar in the browse view has buttons for the following actions: New, Edit, Delete, Duplicate, Move, Sort, Preview and Publish. These options are also available in the context menu that appears when right-clicking on a content item in the tree grid panel.

_images/toolbar.jpg
  • New: Opens the New dialogue for creating new content.
  • Edit: Opens the content for editing in a new browser tab. See Content Editor.
  • Delete: Opens the Delete item dialogue for the selected content. Read about Delete.
  • Duplicate: Makes a copy of the selected content. See Duplicate.
  • Move: Opens the Move item with children dialogue. See Move.
  • Sort: Opens the Sort items dialogue where child items of the selected content can be sorted. See Sort.
  • Preview: Opens the selected content in preview mode, in a new browser tab. If more than one content is selected, each will open in its own tab. Only content that has a supporting page template can be previewed. Read more about Page Templates.
  • Publish: Opens the Publishing Wizard dialogue. Read more about Publish.
  • Unpublish: Opens the Unpublish Wizard dialogue for taking the item offline.
Search Panel

The search panel can be toggled with the magnifying glass icon at the far left of the menu bar. When opened, it has a text search field and categories to limit search results by Content Types and Last Modified. All content will match an empty search field.

_images/search-panel1.jpg

Search results are instantly updated in the tree grid as search parameters are changed. Children of matching content will also exist in the tree grid but won’t be visible unless the parent is expanded with the triangle.

The number of hits will appear below the search field, along with a Clear button that will remove all search parameters.

Each content type that has at least one matching content will appear in the Content Types list with the number of matches in parenthesis (). Checking the box next to a content type will remove the results that do not match that type. Multiple content types can be “checked”.

The Last Modified list works in a similar manner. It is used to limit results to content that has been modified in the last month, week, day or hour. This list may not appear if other search parameters have limited results to content that was modified more than a month ago.

Tip

Search results remain in the tree grid when the search panel is closed. Don’t forget to clear the search when finished with it.

Content tree grid

The content tree lists all the content that the logged in user has read access to. Content can be organized and stored in a hierarchy with child content collapsed under parent content. Parent content will have a gray triangle to the left of the content icon that can be clicked to expand or collapse the view of its children. The content tree can also be navigated with the keyboard arrow keys. The top of the content tree has buttons to select all displayed content, clear selected content and refresh the tree.

_images/content-tree-grid.png

Information about the content is displayed in three columns. The first column has an icon based on the type of content. A gray triangle will appear to the left of the icon if the content has children content. The first column also has a display name and under this is the path name. The URL path to any content can be determined by following the tree grid path names from parent to child. The second column shows the status of the content which will be Offline, Online or Modified. The third column shows the date that content was last modified.

If current user has only read access to a content item, such item will be slightly dimmed in the grid.

Checkboxes to the left of each content in the tree can be used to select more than one content. The checkbox in the toolbar will select/deselect all content. Group actions available in the menu bar will be performed on all the selected content. Some actions can only be performed on one content at a time.

Double-click on a content item will open it for edit in a new browser tab.

Right-click on a content item will expand its context menu.

Preview panel

A preview of the selected content appears in the right-hand panel of the Browse View if page template supports the type of content selected. This is a working preview so links will take you to other pages and highlight the new page content in the content tree grid. The Preview button in the toolbar will open the page in a new browser tab. When more than one content is selected in the content tree grid, the preview panel is replaced with a list of all selected content items. If preview is for some reason unavailable the panel will indicate the reason with a message.

Note

Only the Draft version of content is visible in the preview panel.

Detail panel

The detail panel displays built-in and custom widgets with information about the content, selected in the tree grid. To see it, click the detailicon button in the top right corner. This reveals the panel selector, which by default show details about the content. The details are split into several boxes that show:

  • Icon, name and path of selected content
  • Content status (Online, Offline, or Modified)
  • Permissions: The permissions section has three parts. First it shows an unlock icon unlockicon if the content has the role Everyone, which means the content is viewable without authentication. Second, it lists the users that have access to the selected content at each access level, for example, “Can Read” or “Full Access”. Third, it has a link to edit permissions if the logged in user has the Content Manager Administrator role or other applied permissions to edit the content.
  • Basic information about the selected content, including type, application, language, owner, timestamps and ID
  • Rendering Mode, which reveals if the content is rendered by a custom built page, a specifically selected page template, or an automatically selected page template.
  • File attachments
_images/content-detail-panel.png
Widget selector

The dropdown menu on the top is a widget selector control with the installed widgets listed. In addition to the Details widget, the Version history and Dependency widgets are built-in. Others can be added with the Applications admin tool. When a widget is selected, everything below it in the details panel is replaced with whatever the widget is designed to display. To the left of the widget selector the detailicon button is available to hide the detail panel.

_images/widget-selector.png

Tip

Widgets are user-definable. Read more about how to create your own Widgets.

Widgets

Widgets are apps that add functionality to the Content Studio. As of version 6.12, there are three built-in widgets. The Detail panel was described on the previous page. Here follows descriptions of the version history and dependency widgets. Installed widgets are listed in a dropdown selector at the top of the panel.

Tip

Widgets are user-definable. Read more about how to create your own Widgets.

Version history

Every time a content is saved with changes, a new version is created. The Version history widget displays a list of each version for a selected content. This widget also allows the user to switch between versions of a content.

Each version item in the list displays the name of the user who made the changes and the length of time since the change was made. If the content has been published then the published version will be marked as “Online” with a green heading.

Selecting one of the version items will expand it to reveal the timestamp, version id, and the display name of the content.

_images/version-history.jpg
Active version and online version

Every content has one active version. A published content will also have an online version. The active version is the one shown in the preview and the one that will be loaded into the content editor when the content is edited. When a content is published, the active version is the one that goes online so it will be both the active and online version.

The active version can be changed by restoring a different version. If the active version is older than the published version, it will be listed as “Out-of-date”. The active version will be listed as “Modified” if it is newer than the online version.

Restoring a version

Any version can be set as the active version by selecting it and clicking the button labeled “Restore this version”. Doing so will not change the published (online) version. This means that a previously published version of the content will remain online when a version is restored. A content must be published before the restored (active) version goes online.

Dependencies

Content can be configured to use content of other types. For example, an article content might use a ContentSelector for adding pre-defined categories. The dependencies widget makes it easy to find all the content that uses, or is used by, the selected content.

Select the Dependencies widget in the details panel and then select a content in the tree grid. The icon, name, and path of the selected content will appear in the center of the details panel. An icon for each type of inbound dependency is listed at the top-left. Icons for each type of outbound dependency are listed at the bottom-right. Next to each content type icon is the number of dependent items of that type.

_images/dependencies-widget.jpg

Inbound dependencies are other content items that use the selected content. Outbound dependencies are the content items that are used by the selected content. For example, the image above shows a Post content named March Madness. This Post has five inbound Comment items that reference the March Madness post. The Post itself references one image content, one Author content, and two Category contents. Therefore, the image, Author and Categories are outbound.

Inbound and outbound content can be viewed by clicking the respective buttons at the top and bottom of the dependencies widget. This will open the search panel on the left and filter the tree grid to show only the selected dependency type.

Content Editor

The Content Editor opens in a new browser tab from the Browse View when a content is created or edited. Multiple content tabs can be open at the same time. Clicking on the Content Studio tree icon in the top left corner will open Browse View in a new browser tab. User will get a browser warning upon trying to close a tab with changed but unsaved content.

The edit view consists of several parts. On the left is the Content Form. If content is editable, the Page Editor will automatically open on the right. Expandable Context Panel and Components Panel can be open from inside the Page Editor. Inspection panel will be placed to the right of the Page Editor or expand over it, based on screen resolution. The Components view will always hover over the Page Editor.

_images/edit-view.jpg
Content Form

This panel appears on the left side of the page when content is created or edited. It is where the form appears in which content data is entered. The structure and fields in the form are determined by the content type which is defined in the application code. The content editor panel can be collapsed to give the page editor more room by clicking the arrow icon on the top right of the panel.

The top of the content form has the content type icon, the Display Name, and the content path name. The default icon can be replaced with an image file by clicking on it. As the Display Name is entered, the path name will automatically be filled in with a URL-friendly version. The path will not update automatically once the content has been published. This is to prevent accidental breaking of external hard-coded links. The path name can always be changed manually. It is also possible for the Display Name to be generated automatically while other fields in the form are filled in if the content type was set up that way in the application code.

_images/content-editor1.png

Next is a ribbon with buttons that correspond to different sections of the content form. All content will have buttons for the content type name, Settings, and Security. All published contents will have an additional button Schedule. Other items may be in the ribbon if x-data was added to the content type in the application code. Clicking on an item in the ribbon will scroll the content editor to the corresponding section of the form.

_images/content-editor2.png

The content data section is next and the form fields will depend on how the content type was set up.

The Settings area is where the content’s Language and Owner are set. The Language will be inherited from the parent content if it was set there. The Owner will be the logged in user who created the content, but it could be changed if the current user has the right permissions.

The Schedule area is where the period of time, during which a content is available online, can be modified. This area is only displayed for published content.

The Security section is where the content’s permissions are set. Content will inherit the permissions of the parent content when created. Users, Groups and Roles are principals that can be added to the content. Clicking on any item here will expand it and show what permissions the principal has. Read more about Content Security.

Page Editor

The page editor is a modifiable preview of the content page that will open automatically when a content that has a supporting page template is created or edited. It is used in conjunction with the Context Panel to add, remove, and move components around the page with drag and drop. The page editor can be closed and reopened with the icon on the far right of the toolbar that looks like a computer monitor.

A component can be selected in the page editor by clicking on it. This will highlight the selected component and show its configuration in the inspect panel. Right-clicking a component will open a context menu with various actions that can be performed on the component. These options may include Select parent, Insert another component, Inspect its configuration, Reset the component’s configuration, Remove the component, Duplicate it, and Create fragment from the component.

_images/page-editor.jpg

The page editor will not automatically open if the type of content being edited does not have a supporting page template. However, it can be opened manually and a dropdown selector will appear which can be used to add a page component to render a page. Read more about this in the Page Templates section.

Context Panel

This panel is a multi-function tool that can be toggled open and closed with the cog icon at the right of the toolbar. It is used in conjunction with the Page Editor to add and configure components on the page and to emulate various device sizes. The inspection panel has three tabs: Insert, Inspect, and Emulator.

Insert tab

This tab has a list of Component types that can be added to the page in a two step process. The first step is to drag and drop a component type placeholder to a region in the page editor. The second step is to select the specific component from a dropdown selector in the placeholder.

_images/inspect-insert.jpg

For example, to add a part component called “Categories” to the page, simply click the part icon (puzzle piece) and drag it to a region in the page editor. A red circle appears when the component is dragged over an area where it cannot be dropped. A green checkbox appears when dragged over valid locations and a blue box shows where the component will land. Once the part placeholder is dropped, it will have a combo-box where the “Categories” part can be selected from the list. When a component placeholder is selected, the inspection panel will also show a combo-box with a list of available part components.

Inspect tab

This is where components are configured. The inspection panel displays form inputs matching the configuration of whichever component is selected in the page editor. Some components won’t have any configuration settings. The page will not update as configuration values change until the content is saved or when changes are applied with the button at the bottom of the panel.

The inspect tab is also used for changing the default page template of a selected content and choosing a page component to render content that does not have a supporting page template. Read more about this in Page Templates.

Emulator tab

This tab has buttons for emulating various sized devices. The page editor will shrink and expand to fit the selected device size.

_images/emulator.jpg
Components Panel

This tool opens in a draggable internal window activated by the clipboard icon in the toolbar. It displays a hierarchical tree representation of all the components and regions on the page, including the page itself. This tool is extremely valuable in situations when an unconfigured component does not render or content structure is complex or device resolution is very small.

Selecting a component in the tree will highlight the component in the page editor and display its configuration in the inspection panel’s Inspect tab. The triangle on the right of each component will open a menu of options that can be selected for the component. The menu options available depend on the component selected, but may include: Insert for inserting other components, Reset to reset the component’s configuration, Remove, Duplicate and Create fragment.

Components can be rearranged directly in the tree with drag’n’drop function.

In the image below, a part named Meta is selected in the Components view and the part is highlighted with a black border at the bottom of the page editor. The Meta part’s configuration is visible in the inspect panel on the right.

_images/components-view.jpg
Component types

Enonic XP has five types of components that can be added to regions on a page. These component types are listed under the “Insert” tab of the page editor. This section covers each type of component in detail. See the Page Editor and Context Panel pages for more information about editing pages.

Image component

The Image component allows content editors to place an image into any region on a page without writing any code.

In the Page Editor, drag an Image component placeholder from the inspect panel to the desired region on the page. Once placed, the empty image placeholder contains an image selector that can be used to find and select any previously uploaded image content. If the name of the image is known, simply start typing it in the box to filter the list of images. If the name is not known, use the down arrow to open a list of images to choose from. Note that the list will contain all image content items in the XP installation, including images that were created in a different site of a multi-site environment.

If the desired image does not already exist as a content, simply upload it with the button on the right side of the image selector dropdown. The new image content will be created as a child of the page being edited, but it could be moved later if needed.

The inspect panel will also show the dropdown image selector as well as a text area for writing an image caption. If a caption is entered, it will appear below the image.

_images/image-component.jpg
Part component

Part components are reusable, configurable components that can be placed into any region of a page with the page editor Context Panel. This allows content editors to build and customize pages without writing any code. There are no built-in part components. Each one is custom made in the application code. Parts are typically created to render custom content, lists of content, forms, etc.

The first step in adding a part component to a page is to edit the page content and open the inspection panel’s “Insert” tab. Drag the part component placeholder (puzzle piece) to the desired location on the page. The part placeholder will now appear as a blue box with a dropdown selector. The same part dropdown selector will appear in the inspect panel. Use one of the selectors to find the desired part component. Once a part component is selected, the placeholder will be replaced with the actual part and the Inspect panel will show the part’s configuration options in a form.

Some parts won’t have any configuration. Parts with configuration options are independently configured. This means that the same part component can be added to multiple pages, or even multiple times in the same page, and each instance can have different configuration values.

_images/part-component-selector.jpg
Layout component

Layout components are reusable, configurable components (similar to Part components) that can be placed into any region defined in a page component. Layouts themselves define regions where other components can be placed with the Page Editor. The primary purpose of a layout is to enable other components to be placed side-by-side. As of version 6.12, a layout cannot be placed inside another layout. There are no built-in layouts. Each one is custom made in the application code. Layouts are typically created for two or three columns and have configuration options for column widths.

In the Page Editor, drag a Layout component placeholder from the inspect panel to the desired region on the page. The layout placeholder will now appear as a blue box with a dropdown selector. The same dropdown selector will appear in the inspect panel. Use one of the selectors to find the desired layout component. Once a layout is selected, the actual layout rendering will replace the placeholder and its configuration options will appear in the inspect panel. Some layout components may not have any configuration options.

_images/layouts.jpg

While editing a page, it may be difficult to select a layout to access its configuration. In this case, the Components Panel can help to select the layout. Alternatively, a part within the layout can be selected and then that part’s parent can be selected from the right-click context menu. Continue selecting the parent component until the layout is the selected component.

Text component

Note

This section is under construction. This information is likely incomplete and possibly inaccurate until this notice is removed.

The Text component allows content editors to place and format text into any region on a page without writing any code. Images can also be added inside text components. Macros allow Twitter tweets, YouTube videos, embedded code, and no-format text to be added as well. The formatting and macro options are the same as those for the HtmlArea inputs that can be found in content types and other configuration forms in the Content Studio. The only difference is that the formatting toolbar is at the top of the page for text components.

In the Page Editor, drag a Text component from the inspect panel to the desired region on the page. A cursor will appear inside the text component and editing can begin. If another component is selected, the text component will need to be double-clicked to resume editing.

Fragment component

Fragments are created as content from an instance of another component. What makes a fragment special is that it uses the same configuration on every page where it’s added. When a fragment content is altered, the change is instantly visible on every page that uses it. All of the other components are independently configured.

Creating fragments

Fragments can be created from any component on a page. When a fragment is created, it makes a content copy of the part, layout, image or text component. In the page editor, right-click the desired component and select “Create fragment” from the context menu. The new fragment content is created as a child of the page being edited. The fragment content will open in a new editor tab where its name and configuration can be changed. At the same time, the component that was copied is replaced with the new fragment.

Using fragments

Once a fragment content has been created, it can be added to pages with the page editor. Drag a fragment placeholder from the “Insert” tab of the Context Panel to the desired location on the page. Use the dropdown selector in the placeholder to find the desired fragment content. Once selected, the fragment will appear.

_images/fragments.jpg
Input types

Some of the input types will be familiar from standard web forms. Other input types are specific for editing content and configurations in Enonic XP. Most inputs can be navigated and operated with the keyboard. Inputs can have their own configurations which are defined in the application code and affect how they work.

All inputs have some common features. For example:

  • Each input has a label.
  • Each input can have an optional help text.
  • Required fields are marked with a red asterisk.
  • Input fields may be repeatable so that they can have multiple values. Repeatable inputs will have an Add button below the field.
Standard input types

These are the familiar input types that are used all over the web. They function the same as you would expect.

TextLine

A text line is used for capturing a single line of text. In the image below, the first TextLine is required and marked with a red star. The second allows multiple entries under the same label. When multiple values are enabled, the order of the entries can be changed by clicking the dotted area to the left of the entry box and dragging them up or down.

TextLine inputs may be configured with regular expressions to allow only valid values with a specified structure. The box becomes red when the value does not match the regular expression.

TextArea

The text area is used when the expected value to be entered is too large for a text line. Multiple lines of text are allowed. There are no formatting options available for a text area. The box will expand vertically as more text is entered.

CheckBox

The checkbox can be toggled between checked or unchecked by clicking the box or the label with the mouse or by pressing the space-bar when it has focus. Checkbox position in relation to its label is configurable.

RadioButtons

This type of input allows the user to select one of several options. When one option is selected, a previously selected option will be unselected. The options can be navigated with the keyboard arrows.

_images/inputs-standard.jpg
Selector input types

These input types allow selections from a list of options.

Attachment uploader

Files can be selected for upload with this input type. The uploaded files will exist as attachments to the content being edited rather than as a content of their own.

Clicking the upload button to the right of the label will open your machine’s native file browser where one or more files may be selected. Attached files are listed by name and may be removed by clicking the X to the left. The files may also be downloaded by clicking the file name.

_images/inputs-attachment.jpg
ComboBox

This input type allows the selection of one or more predefined options. Clicking the down arrow in the right of the box will open a list of options. Typing in the box will filter the options in the list.

If the input is configured for more than one selection then a checkbox will appear to the left of each option. The Apply button appears in the box when changes are made and it must be used to accept the changes.

Selected options can be removed by clicking the X to the right of the selection text.

_images/inputs-combobox.jpg
Content selector

Content selectors allow the selection of one ore more existing content items. They can be configured in the application code to list only specific types of content and/or content that exists at a certain path of the content tree.

Content selectors behave much like combo boxes. The down arrow in the right of the box opens the list. Typing in the search field will filter the content by name. When more than one content has been selected, the order my be changed by clicking and dragging the dotted area to the left of each content. Any selected content may be opened for editing by clicking the pencil icon. Selected content can be removed with the X icon.

_images/inputs-content-selector.png
Image selector

Image selectors are much like content selectors except that they allow only image content to be selected. They also allow new image content to be created and selected by clicking the upload button to the right of the input. When multiple images are selected, the order can be changed by clicking and dragging the image previews. Clicking on a selected image will reveal Edit and Remove buttons.

_images/inputs-image-selector.jpg
Tag

Tags allow the selection of previously entered tags and also allow the creation of new tag options. Start typing in the box to reveal matching options. If the desired tag is found in the list, use the arrow keys or click to select it. If the desired tag has not been entered before, simply finish typing and press enter/return. Added tags can be removed by clicking the X next to each tag.

_images/inputs-tag.jpg
Custom selector

Behavior of Custom selector is similar to that of Content selector except that the list of options in the dropdown is built based on custom data source. Application developer must create a service that returns JSON in correct format required by the input. Name of this service must then be specified inside the input configuration in the application code. Each option in the JSON must have a unique Id and display name (required), and, optionally, description and thumbnail (either as an external URL or inline SVG).

_images/inputs-custom-selector.jpg
Html Area input type

There are three input types for entering text. The Text Line and Text Area are covered in the Standard input types page. This section will cover the HtmlArea.

The HtmlArea is a special input type that allows text to be formatted in various ways. Code and iFrames can be embedded with macros. Images and content links can also be inserted. The editing features of the HtmlArea are the same for the Text component, except that the toolbar for the text component appears at the top of the page.

_images/input-htmlarea.jpg
Toolbar

The toolbar has buttons for various formatting options as well as inserting things like pictures, links, special characters and more.

Formats

The “Formats” button opens a menu with submenus for Headings, Inline, Blocks, and Alignment.

The Heading submenu has options for turning a line of text into an Html heading. These options range from h1 (largest) to h6 (smallest).

The Inline submenu has options for converting text to bold, italic, underline, strikethrough, superscript, subscript and code. The code option makes text monospace.

The Blocks submenu will wrap a block of text in HTML elements for Paragraph <p>, Blockquote <blockquote>, Div <div>, and Pre <pre>.

The Alignment submenu has options to align a block of text to the left, center, right, or justify.

Alignment

The next four icons can be used to change alignment of selected element: left-align, center, right-align or justify.

Lists

The next two icons will turn text into a bullet list or a numbered list. Pressing “enter/return” will make a new list item and pressing it a second time will end the list. Use shift + enter/return to make a new line within the list item. A sub-list can be created with the indent button.

Indent

The next buttons will decrease and increase indent for the selected text. These buttons will also increase or decrease the level of a list item.

Special character

This button opens a menu with 250 special characters. Selecting one will insert it at the cursor’s location.

Anchor

Anchors are places in the text that links can send the user to. If a link references an anchor on the same page then the page will scroll up or down to the location of the anchor. The anchor button in the toolbar opens the Insert Anchor dialog where the name of the anchor is entered. The anchor name will be used as the value of the “id” attribute, so it should be lower case without spaces.

Insert/Edit image

This button opens the Insert Image dialog. An existing image content can be selected from the “Image” selector, or a new image can be uploaded by clicking the upload button. Once an image is selected, some formatting options appear. The image can be floated to the left or right so that text wraps around it. The image can also be centered or set to full width. A checkbox allows you to keep the image at its original size. A Cropping effect selector has options for various aspect ratios. A caption can be entered at the bottom.

Insert macro

This button opens the Insert Macro dialog, which contains a selector for choosing a macro. Macros allow all sorts of things to be inserted into the input, such as iframes, YouTube videos, Twitter Tweets, etc. There two built-in macros and others can be added with applications. Once a macro is selected, a form appears with inputs for the macro’s configuration settings.

Table

This button expands a dropdown menu enabling you to insert a new table, manage table properties or add/delete columns/rows in existing table.

Paste as text

The paste button is actually a toggle setting that controls how text is pasted. The icon is highlighted blue with the default mode which removes the source formatting from text when it is pasted. Click the icon to change modes. With plain text disabled, any formatting applied on the source of the text will come with it.

Tip

Although HTML Area comes with default toolbar, it can be customized to exclude specific (or all) tools and/or include other tools that are supported. Read about this in description of HtmlArea input config.

Tip

Read about keyboard shortcuts supported in the HTML Area in our Keyboard shortcuts section.

Date and time input types

There are three input types for entering dates and times: Date, Time, and DateTime. Each input has a date/time-picker tool. Values can also be manually typed into the input fields. The input turns red if the value is not in a valid format. These inputs can have default values (set in the application code) and the defaults can even be relative to the date and time that the form item was created.

_images/inputs-date-time.jpg
Date

The date input filed allows text to be entered in the format of YYYY-MM-DD. The input block turns red when the date is entered with an invalid format. The button on the right opens a date-picker tool. Date inputs can be configured to have a default value. The default date could even be relative to the current date, for example, one month from the time that the content with thie input was created.

_images/input-date.jpg
Time

The time can be entered manually in the 24 hour format HH:MM. Invalid entries will turn the input red. A button in the right of the form will open a time-picker tool for easily selecting the desired time. The input could be configured with a default value.

_images/input-time.jpg
DateTime

The DateTime input contains both the date and the time. A value can be entered manually in the format “YYYY-MM-DD HH:MM”. A date-time picker tool can be opened with the button on the right side fo the input.

The input can be configured to include the timezone. The timezone will be the same as that of the Enonic installation server and it is not editable in the data-time picker tool. However, the timezone can be changed by manually entering a date in ISO 8601 format 2016-06-17T12:59+03:00. A default value can be set.

_images/input-date-time-picker.jpg
Numbers and GeoPoint input types

There are four ways to input numeric data. Double and Long ensures the data is treated as numeric on the back-end as well. GeoPoint is a very special input type for registering a Geo Point world coordinate. All of these input types have validation rules to ensure correct input.

_images/inputs-numbers.jpg
TextLine with RegExp

A TextLine input can be configured with a regular expression in the application code to allow only numbers.

Double

A double is a number with a decimal point.

Long

A long is a large number. The maximum value that can be entered as a long is 8999999999999999.

GeoPoint

A Geo Point stores geographical coordinates with the latitude and longitude separated by a comma.

_images/input-types.jpg

All inputs can have an optional help text that will be shown next to the input. It’s hidden by default but can be turned on by clicking the “?” icon next to the input label.

Note blue “?” icons next to the Checkbox and the GeoPoint fields in the form below - for these two fields the help text is turned on. The ComboBox field also has a help text, but it’s hidden - the “?” icon is inactive and must be clicked to show the help text.

_images/input-types-help-text.jpg

It’s also possible to turn on help text for all inputs on the form at once by clicking the “?” icon inside the Content Wizard toolbar.

_images/input-types-help-text-all.jpg
Content Security

Security of a content is determined by the principals and permissions in the content’s security settings. Principals are Users, Groups and Roles which are managed in the Users admin tool. Principals are added to each content. Permissions are granted to the principals of the content.

Principals

Individual users could be added to each content. But security is easier to manage by adding groups and roles to each content and then granting the appropriate permissions to these groups and roles. When a group is added to a content then all users who are members of that group will have the group permissions for that content. Similarly, when a role is granted permissions to a content, all users who have that role will also have those permissions.

Permissions

Permissions are granted to principals on a per-content basis. This means that changing a principal’s permissions for one content does not affect that principal’s permissions for other content. Below is a list of permissions that can be applied to each principal for any content.

  • Read: The principal can see this content.
  • Create: The principal can create child items under this content. For example, if a user has this permission on a folder then the user can create new content in the folder.
  • Modify: The principal can edit this content and save changes in the draft branch.
  • Delete: The principal can delete this content from the draft branch. If the content is published then its status can be changed to “Pending delete”.
  • Publish: The principal can publish this content to the master branch. Can also remove content that is “Pending delete”.
  • Read permissions: The principal can see this content’s permissions.
  • Write permissions: The principal can change this content’s permissions.

Permissions can also be denied to a principal, even if the permissions would otherwise be granted from another principal. For example, all content editors might be added to a group called “Content editors” which has the Can Publish permissions. But new content editors might break stuff, so they would also be added to a group called “Noobs”. Users in this group could be prevented from publishing and deleting content by denying those permissions to the group.

Public content

For a content to be accessible to the public, (meaning users who are not logged in), it must have the role Everyone with the Read permission. The content must also be published. Content without the Everyone role can only be seen by users who are logged in and have read access to it through one of the content’s principals.

Editing permissions

When a site is first created, it will have the roles Administrator and Content Manager Administrator with full access. It will also have the role of Content Manager App with read access. When content is created it will inherit the security settings from its parent content. The security settings for any content can be changed through the Edit permissions dialogue. This can be accessed with the Edit Permissions button in the Security section when editing a content, or by the button in the details panel in browse view.

_images/edit-permissions.jpg

Opening the Edit Permissions dialogue shows a list of the current principals and their permissions for the content. By default, all content will inherit permissions from its parent. Permissions cannot be changed until the box for Inherit permissions is unchecked. Any changes that are made will also be applied to all child items that directly or indirectly inherit permissions from this content. There is also a checkbox at the bottom of the dialogue labeled Overwrite child permissions. Checking this box will force the new permissions on child content that do not inherit permissions.

When the Inherit permissions checkbox is unchecked, a dropdown selector will appear for adding new principals. The permissions for each principal in the list can be determined by the settings in blue letters on the right. Clicking a setting will open a menu with the available options that can be applied, which are listed below:

  • Can Read: Has only the Read permission.
  • Can Write: Has permissions for Read, Create, Modify, and Delete.
  • Can Publish: Has permissions for Read, Create, Modify, Delete, and Publish.
  • Full Access: Has all permissions.
  • Custom: Any combination of permissions.

Selecting “Custom” will list all of the permissions. Clicking on a permission will toggle it between white (not granted), green (granted) and red (denied).

Publishing Issues

Publishing Issues is a way to create, delegate and follow up tasks for publishing one or several content items. The list of publishing issues can be open by clicking issueicon icon in the top right corner of the Browse View. A new issue can be created either from the Issue List dialog, Publishing wizard or from the Publish button’s menu in the Browse view’s Toolbar.

_images/publishing-issues-list.png

If current user has any open issues assigned to him this will be reflected on the Issue icon: notificationicon.

New Issue

There are several ways to create a new issue.

From the Issue List dialog

Click the issueicon icon in the top right corner of the Browse View. This will open a dialog with the Issue List.

_images/publishing-issues-list-empty.png

In this dialog click the “New Issue” button to open the “Create Issue” dialog.

_images/publishing-issues-new-empty.png

Fill out title and description of the new issue, select one or more assignees and content that is supposed to be published within the issue. Use the includechildrenicon icon to flag content items that must be published with all of their child items. Use “X” icons in the list to exclude items that should not be published within the issue.

_images/publishing-issues-new-issue.png

Click “Create Issue” button to create the issue or “Cancel” to return to the list.

From the Publishing Wizard

Inside the Publishing Wizard you can expand the Publish button’s dropdown menu and select “Create Issue” option.

_images/publishing-issues-create-issue.png

This will open the “Create Issue” dialog similar to the one above except that the list of content items will be based on selection in the “Publishing Wizard”. Use backicon in the top left corner of the dialog to return to the Publishing Wizard if you want to make changes to the list of contents.

From the Publish button menu

In the Content Grid select content items that you want to add to a new issue. Expand the dropdown menu of the Publish button in the grid’s toolbar and select “Create Issue”. Again, this will open the “Create Issue” dialog with preselected items from the grid selection.

_images/publishing-issues-create-issue-toolbar.png

No matter which way was used to create a new issue, once it was successfully created the user will be redirected to the new issue’s details dialog:

_images/publishing-issues-existing.png

After a new issue is created, both creator of the issue and all of the assignees will be notified by email.

Issue List

The list of Publishing Issues can be opened by clicking the issueicon icon in the top right corner of the Browse View.

_images/publishing-issues-list.png

The list is split in two tabs: Open and Closed, with open and closed issues respectively. Filter on top of the list can be used to narrow down the list to only the issues assigned to you or created by you. Black circles next to each issue indicate assignees the issue is assigned to. Clicking an issue will open the Issue Details dialog. “New Issue” button opens the New Issue dialog.

Issue Details
_images/publishing-issues-existing.png

The dialog with issue details can be open from the Issue List or via direct link from an email confirmation sent to assignees. It will also open automatically after a new issue is created. By default the dialog is in read-only mode and shows issue title, id, brief summary, status, description, assignees and the list of contents. Use backicon in the top left corner to go back to the Issue List.

“Edit Issue” button in the bottom-left corner can be used to switch the issue to edit mode and make changes to it. Pressing the “Publish” button will publish all of the items in the issue along with their dependencies and - optionally - child items. After an issue is published its status will change from Open to Closed and user will be redirected back to the issue list. Both creator of the issue and all of the assignees will be notified by email that the issue was published and closed.

Edit Issue

An issue goes into edit mode with a click on the Edit Issue button in the Issue Details dialog.

_images/publishing-issues-edit-mode.png

Here you can change issue properties, assignees, the list of contents etc. Click “Save” button to apply the changes or “Cancel” to close edit mode without changes. After an issue is modified, both creator of the issue and all of the assignees will be notified of the changes by email.

Issue Status

Status of an issue can be changed from Open to Closed or back at any time (even in read-only mode) by clicking the status button in the Issue Details dialog. This will expand a dropdown with available statuses - just select one and the issue will be updated at once. As always after issue modifications, an email will be sent to both creator of the issue and all of the assignees to notify them of the changes.

Note that changing issue status will change its location in the Issue List - it will be moved from Open tab to Closed tab or the other way around.

_images/publishing-issues-status.png

Content Types

Some content types are built into Enonic XP. A basic understanding of these will be essential to building sites with the Content Studio.

_images/content-types.jpg
Folder

Content of type Folder is only used to group other contents. Folders have no data fields other than the display name and path name. They also have the Settings and Security sections like any other content.

_images/folder.jpg
Shortcut

Shortcuts create a content path that will redirect to another content. This allows a content deep inside a site to be accessed with a short URL.

For example, a content in the “Posts” folder named “Gotham sure is a big town” would normally be reached at a URL with superhero/posts/gotham-sure-is-a-big-town. But a shortcut as a first child of “Superhero” would make it available at superhero/gotham.

Each shortcut has a required Target field. The selected target content can be edited with the pencil icon.

In addition it is possible to set custom parameters as a list of name-value pairs. These optional parameters will be added to the redirect URL.

_images/shortcut.png
Site Content

Sites are usually created at the root level of the tree grid from a special built-in content type represented by a globe icon. Site contents have a textarea field for the site description and a dropdown selector for adding and configuring applications. Every site content will have a Templates folder which is automatically created along with the site content.

_images/sites.jpg
Applications

Applications contain all the code behind a website. Apps are installed with the Applications tool and apps are used by adding them to a Site content. Some apps will have components for building a site and others will only add functionality to existing sites. Sites will need at least one app that has at least one page component before any rendering can happen.

Edit a Site content and add the desired apps with the Applications dropdown selector. Only users with the role “Administrator” or “Content Manager Administrator” can add an application to a site. The image below shows the edit view for the Superhero Site content. This site has two applications: one is the Superhero theme which was used to build the site and the other is the SumoMe App that adds some functionality.

_images/site-apps.jpg
Configuration

Apps that have been added to a Site are listed in the content edit panel with the display name and app name. The X icon removes the app from the site and the pencil icon opens the application configuration dialogue with the current values. Only users with the role “Administrator” or “Content Manager Administrator” can remove an application from a site or edit application configuration. The configuration options available are defined in the application code.

_images/site-app-config.jpg
Page Templates

A page template is special content that enable other content to be rendered as pages. Page template must support one or more content types. When a request endpoint matches a content path, the content’s supporting template will be used to render it. The Page Editor is used to build page templates by placing the desired components into regions on the page in the desired locations.

Page components

Page components are defined in the application code and contain the basic HTML structure of all rendered pages. Each page template uses one page component. They usually contain the page header, footer and menu. Most page components will have one or more regions where other components (parts, layouts, etc.) can be placed with the page editor. A single page component can be used by any number of page templates.

Creating page templates

A page template can only be created in its site’s Templates folder. Create a new template content here and choose which content types will use it for rendering with the dropdown selector labeled Supports. A dropdown selector on the right side of the page is used for choosing the page component. Once a page component is selected, the page preview will be visible in the page editor. Use the inspect panel or the component view to add components to the region(s) in the page.

_images/templates.jpg
Customizing content

More than one page template can support the same content type. In this situation, the template that appears first in the Templates folder will be used to render the content by default. But individual content can be manually configured to use any template that supports its type. For example, in the image below there is a content type called “Post” and two templates that support the Post type, first is “Post show - 2 columns” and then “Post show - 1 column”. The “Post show - 2 columns” will be used automatically by all Post content. To force an individual Post content to use the 1 column template, edit the content and select the 1 column template in the Page Template dropdown at the top of the Inspect panel.

_images/template-selector.jpg

Individual content can also be customized to render differently. To customize a content, edit it and click anywhere on the page in the page editor. A context menu appears with a “Customize” button. Once that button is clicked, components on the page can be moved with drag and drop, or removed from the page and other components can be added.

Rendering other content

Even content that has no supporting templates can be rendered as a page. For example, if a site has a Folder content called “Articles” and it has child Article content then it might be desirable to render the “Articles” folder as a page with a list of the articles that it contains. This is achieved by adding a page component to the unsupported content with the page editor. Edit the content and open the page editor. Select a page component from the dropdown selector and then add components (parts, layouts, etc.) to the page.

_images/page-component.jpg
Templates folder

The Templates folder is just like a regular folder except that it has a special icon and it can only contain Page-template content. When a Site content is created, a Templates folder is automatically created with it as a child of the Site.

Unstructured

Unstructured content cannot be edited in the Content Studio except for the display name, the content name, and the settings and security. Content of this type is meant to be used by applications to store data when the structure is not known. Form entries are often stored as unstructured content to avoid the need to create a custom content type for each form on a site. The stored data cannot be viewed in the Content Studio without a custom page component or page template that supports the Unstructured content type.

Image content

An image content is created when an image file is uploaded. Storing images as content allows them to be indexed for searches and have the same language and security settings as other content. Image content items have fields for Caption, Artist, Copyright, Tags and Text. Image content also has fields that are automatically filled in with any Exif data the image file contains. The image file itself can be swapped out with the upload button or by dragging a file onto the image. Images can be cropped and a focal point can be added in the editor.

Cropping

Clicking the crop icon (above the image) will darken the page outside of the image preview and the editing tools. The zoom slider will make the preview larger and parts of the image will extend into the dark regions of the page. The image can be moved by clicking and dragging it around. The aspect ratio can be changed by clicking and dragging the circle (arrows icon) at the bottom of the picture. Make the necessary adjustments so that the part of the picture you want to keep is within the highlighted area. The Apply button will restore the page to normal edit mode.

_images/image-cropping.jpg
Focal point

Images can be displayed on a web page with a different aspect ratio than the original. When this happens, the top and bottom or the left and right edges of the picture will be automatically cropped. This can cause the subject of the image to be lost. For example, the heads of people in a portrait image could be cut off when the image is rendered with a landscape ratio. Setting a focal point on an image ensures that the subject will always be in the picture, no matter the ratio used to render it.

Click the focal point icon. A red circle appears in the center of the image preview. Click on the part of the picture that you want to always keep in frame and then click the Apply button. Once a focal point is set, its location will be marked with a red circle when the content is in edit mode.

_images/image-no-focal-point.jpg

In the image above, the original picture has a tall aspect ratio. No focal point is set.

_images/image-focal-point.jpg

Setting the focal point.

_images/image-with-focal-point.jpg

The giraffe’s head remains in frame with the focal point set.

Actions

Content can be created, edited, deleted, duplicated, moved, sorted and published.

New

All content created with the Content Studio begins with the Create Content dialogue. This dialogue has two functions. First it assists the user with finding the type of content to be created. Second, it opens the edit view in a new internal tab.

_images/create-content.jpg

There are three ways to open the Create Content dialogue in the Content Studio. The first method is with the shortcut - alt + n. The other methods require selecting the New button in the toolbar or in the context menu that appears when right-clicking an existing content in the tree grid.

Content will be created as a child of whichever content was selected in the tree grid when the Create Content dialogue was opened. If no content was selected, the new content will be created at the root of the repository. Usually, only Site contents are created at the root.

Search field

The search field can be used to quickly find a content type.

File and image upload

To the right of the search field is an upload button represented by an icon with an up arrow. Clicking this icon will open the user’s file browser so one or more files can be selected from the file system. The type of content created will depend on the type of file selected. Files can also be dragged and dropped onto the Create Content dialogue. A new edit view tab will open for each selected file so that meta-data can be entered.

Content type list

All content types of the installed applications are listed on the left side of the Create Content dialogue. The list is instantly updated as characters are typed into the search field. Each item in the list has the content type icon, Display Name of the content type, and the full app name of the content type. It is possible for two applications to have a content type with the same Display Name, so the full app name would be helpful to tell them apart.

Recently Used

The right side of the dialogue will list the recently used types of content.

Delete

Note

This page is under construction. This information is likely incomplete and possibly inaccurate until this notice is removed.

Content is deleted through the Delete item dialogue. This dialogue can be accessed by the Delete button in the toolbar of both browse view and edit view. It can also be opened from the context menu by right-clicking a content in the tree grid. The selected content is listed along with its status. If the content is a parent then the children contents are listed and will also be deleted. The Delete button shows the total number of items that will be removed. More than one content can be selected for deletion from the tree grid in browse view.

Offline content is removed immediately. Content that is online can be removed immediately by checking the box labeled “Instantly delete published items”. If this box is not checked then the content will only be marked for deletion. Its status will change to pending delete and its name will have a line through it. Content that is pending delete will still be visible outside the Content Studio. Content that is pending delete can be removed and taken offline by publishing or unpublishing it, or deleting it again and checking the box to “Instantly delete published items”.

_images/delete-item-dialogue.jpg

An extra layer of protection kicks in before bulk items or a site content can be deleted. The “Confirm delete” dialogue appears to warn that this action cannot be undone. The number of content items to be deleted must be entered before the deletion will occur.

_images/confirm-delete.jpg
Duplicate

This action will make a copy of the selected content and add “-copy” to the duplicate’s path name. The only other difference between the original and duplicate will be the content ID. Even the Created and Modified dates will be the same. This option is disabled when more than one content is selected in the tree grid.

When used from inside the Edit view, “Duplicate” function will open a new browser tab for the copy of the content and switch to that tab.

_images/duplicate.jpg
Move

The toolbar’s “Move” button opens the Move item with children dialogue. This feature moves selected items with all children and current permissions to another place in the tree grid. Type to search, or use the dropdown arrow, to find the new parent content where the selected items will be moved to. If the “Move” button in the dialogue is clicked without choosing a parent content then the items will be moved to the root of the content tree. Content cannot be moved to a location where another content already exists with the same path name.

_images/move-content.jpg
Sort

Child items of any content can be sorted in a number of ways through the Sort items dialogue. It is accessed with the Sort button in the toolbar or context menu, or by clicking a “sort” icon that appears for previously sorted content.

_images/sort.jpg

The default sorting is by the modified time in descending order. The other options are modified time ascending, DisplayName (ascending or descending), and Manually Sorted. To manually sort items, simply drag and drop them in the Sort items dialogue.

_images/sort-options.jpg

Once items are sorted, the parent content will have an arrow in the browse view tree grid pointed up or down to denote ascending or descending. If the content is manually sorted, an icon with three horizontal bars will appear. Clicking the bars or arrow icon will open the Sort items dialogue. In the image below, the Templates folder has manual sorting and the Posts folder is sorted by DisplayName descending.

Publish

Publishing is a simple but important concept for working with content in Enonic XP. The basic concept of publishing is that it makes content viewable to others outside of the Content Studio.

Draft and master branch

All content created with the Content Studio exists in the draft branch with the status offline. Content in the draft branch can be edited, changed, and previewed until it is ready to go online. Every time a content is saved with changes, a new version is created. (See Version history) When a content is published, the active version is copied from the draft branch to the master branch. Only content in the master branch can be accessed by others outside of the Content Studio, subject to the contents’ security settings.

Content status

Published content will have the status online while content that has not yet been published will be offline. When changes to a published content are saved, the new version becomes the active version but the version that is online is not changed. The status of the new active version will be modified and this content will need to be published again before the changes will be visible outside of the Content Studio.

When a published content is “deleted”, the “Delete item” dialogue offers a checkbox to “Instantly delete published items”. If this box is not checked then the content’s status will be pending delete and it will still be visible outside of the Content Studio. Content that is pending delete must be published, unpublished, or “instantly deleted” before it is actually removed from the master branch.

Publishing wizard

Content is published through the Publishing Wizard dialogue. When a content is selected for publishing, its parents and all the related content will be published with it. For example, in the image below, a Post content named “March madness” was selected for publishing. This post has two related Category contents and a related Author content. Therefore, the categories and author will be published with the March Madness post and the parent folders of the categories and author will also be published. All items that will be published with the selected content are listed in the publishing wizard.

_images/publishing-wizard.png

If the selected content has children then these items can be included by checking the box labeled “Include child items”. The total number of items that will be published is displayed on the Publish button. The green “Publish” button has a menu option for “Publish tree” which simply opens the dialogue with the “Include child items” box checked.

Schedule publish

During the publish of offline contents, the user has the possibility to specify the period of time during which the contents will be available online. By default, the period starts from the time of the publish and has no expiring time. This allow the user to schedule a publish by specifying an “Online from” date/time in the future and, optionally, an expiring date/time. The content status of published contents that are not yet available or not available anymore will have the additional mention “(Pending)” or “(Expired)”.

Note

Changes to online items will be effective immediately - i.e. modified, moved, deleted.

_images/schedule-publish.png
Unpublish content

Previously published content can be taken offline with the “Unpublish” feature. The “Unpublish” dialogue can be opened from the Publish menu in the toolbar or by right-clicking the content in the tree grid and selecting “Unpublish” from the context menu. All of the content’s children will be listed and unpublished along with the selected content. The total number of content items that will be taken offline will appear in parenthesis in the red “Unpublish” button at the bottom of the dialogue.

Content that has the status Pending delete will be removed and taken offline when unpublished.

Applications

The Applications admin tool provides an interface to install, uninstall, start and stop applications for an Enonic XP installation. A list of the installed applications appears in the left panel. Applications in this list can be selected by clicking on them. Information about a selected app appears in the right panel. This information includes the basics such as version, key and system requirements as well as a list of schemas for content types, mixins and relationship types, and also a list of descriptors, which are components for pages, parts and layouts.

_images/apps-tool.jpg

Installing an app

Two methods of installing apps are available with the Applications tool. Both are initiated by clicking the “Install” button in the toolbar which will open a modal dialog.

Install from Enonic Market

Applications from the Enonic Market are listed in the dialog in alphabetical order. Each app in the list has a name, a brief description, version number and an “Install” link that will download, install and start the app. Installation will occur on all nodes of a clustered environment. Clicking the name of an app will open a page on the Enonic Market website with more information about the app. If application is already installed but there’s a newer version of the app on the Market, the download link will say “Update” instead of “Install”. You can use the search field above the application list to quickly filter the list.

_images/install-market.jpg
Install via file upload

An application can also be installed by dragging an application JAR file directly onto the installation dialog. Alternatively, you can click the upload button to the right of the search field and select an application JAR file from your local filesystem. The app will be installed and started automatically when the download is complete.

_images/install-upload.jpg
Manual installation

A third method of installing apps involves placing the application JAR file into the $XP_HOME/deploy folder. It is not possible to do this with the Applications admin tool. Apps installed this way would require the JAR file to be placed in the $XP_HOME/deploy folder on each node in a cluster. Locally installed apps will have a blue circle with an “L” on the app icon in the list of installed apps. The Superhero theme app was installed locally in the image below. Locally installed apps can only be uninstalled by deleting the JAR file in the $XP_HOME/deploy folder.

_images/install-local.png

Users

The Users tool allows the management of userstores, users, roles, and groups. A basic understanding of Enonic XP identity management is essential for the proper management of your applications.

Userstores

All users and groups are created and managed in user stores. Each Enonic XP installation has a System User Store that cannot be deleted. Additional user stores can be created as needed. For example, it might be convenient to use the System User Store for employees who run the website and another user store for customers who log into the public site. Each user store can assign an ID Provider to handle its authentication (see ID Providers).

Create new

To create a new user store, user, user group or role click “New…” in the toolbar. This will open a new modal dialog where you can select what type of object you want to create.

_images/new-user-dialog.png

Note that if there’s more than one user store in the system and you want to create either a user or a group then you will have to select which user store you want to create it in.

_images/new-user-dialog-stores.png

After selecting the type of object a new Wizard tab will open where you can finalize and save the item. Also, if you select an existing user store, user, user group or role in the tree the “New..” button will automatically change to display what kind of object it will create. For example, if you select an existing user in the tree then “New…” will change to “New User”. If you click that, it will instantly open a new Wizard tab, skipping the modal dialog.

_images/new-user.png
User stores

As the <DisplayName> is entered, the <name> field is automatically filled in with a URL friendly version. The <name> field will be part of the user store key and it cannot be changed once the user store is saved.

The ID Provider is for assigning an app that will handle authentication for the user store. ID providers can have their own configuration which can be viewed and modified by clicking the pencil icon.

Finally, the permissions section allows principals (users, roles and groups) to be added to the user store. The Authenticated and Administrator roles are automatically added and they cannot be altered or removed.

When a user store is created, it will automatically have folders for Users and Groups.

_images/user-store.jpg
Users

The System User Store has two built-in users. One is the Super User which has full administrative permissions. The other is the Anonymous User which is the principal used by any site visitor that is not logged in.

Creating users

Besides the modal dialog, a new user can be created by right-clicking the “Users” folder (or an existing user) and selecting “New User” in the context menu. This opens the User editor in a new tab within the page. All the fields are required except for the “Groups & Roles” and the user cannot be “Saved” until the required fields are filled in.

The <Display Name> field will typically be the user’s first and last name with capital letters and a space. The <name> field will be automatically filled in with a URL-friendly version of the <Display Name>. The <name> will be used to log in and it can be manually edited at this time. The <name> cannot be changed once the entry is saved. The Email field must have a valid format and must be unique per user store. The Password field has buttons to show/hide the characters and the “Generate” button will create a random password for you. The password’s strength will be displayed as you type and this ranges from “weak” to “extreme”. Passwords cannot be displayed once the entry is saved.

Groups and Roles can be added to the user now or while editing the entry later.

Once the required fields have valid values, the red exclamation mark in the tab goes away and the user entry can be saved by clicking the button in the toolbar.

_images/create-user.jpg
Groups

Groups assist with managing user permissions for content. For example, all content has security permissions which may include roles, groups and users. If a content has only one group named “Customers” (with read access) then only logged in members of that group can see the content. Groups have no function without Members. Users and other groups may be added as members. Clicking on a group in the Users admin tool will show the group’s display name, principal path, and a list of its members.

Creating groups

Right-click the “Groups” folder in the desired user store and select “New Group” in the context menu. The <Display Name> is what will be listed in the “Groups” folder. The <name> is automatically generated as a URL-friendly version of the <Display Name> and should not be changed. The Description is optional. Users and other groups can be added to the group as “Members”. Users can also be added to a group by editing the user.

_images/groups.jpg

Roles

Roles grant certain permissions to the users that have them. New roles can be created by administrators. The built-in roles are listed and described below.

Administrator

Users with the Administrator role have full access to all content and admin tools through the user interface.

Administration Console Login

Users with this role can log in to the administration console. These users will also require a role for each of the admin tools that the users need access to.

Content Manager App

This role allows users to access the Content Studio. Users can see content and sites, but cannot save changes or publish content.

Content Manager Expert

This role allows access to advanced features in the Content Studio admin tool, including seeing and editing the source code of HTML area fields in content and text components on pages.

Content Manager Administrator

This role allows full access to the Content Studio admin tool, including saving edits and publishing content.

Users App

This role allows view-only access to the Users admin tool.

Users Administrator

This role allows full access to the Users admin tool, including create/edit/delete for userstores, users, roles, and groups.

Authenticated

Users automatically have this role when they are logged into the system in any way.

Everyone

This is a special role that all users and site visitors have. This role is typically used to grant read permissions to publicly available content. Unauthenticated visitors, as well as authenticated users will all have this role.

Query Language

When finding nodes and content you will be using our query language. It is based on SQL and looks very similar.

queryExr

Grammar:

queryExpr = [ constraintExpr ] [ orderExpr ] ;
  • If no constraint-expression is given, all documents will match.
  • If no order-expression is given, results will be ordered by _score descending.

Examples:

myCategory = 'article'
myCategory = 'article' ORDER BY title DESC
ORDER BY title

constraintExpr

Grammar:

constraintExpr = compareExpr
               | logicalExpr
               | dynamicConstraint
               | notExpr ;

compareExpr

Grammar:

compareExpr   = fieldExpr operator valueExpr ;
fieldExpr     = propertyPath ;
operator      = '=', '!=', '>', '>', '<', '<=', 'LIKE', 'NOT LIKE', 'IN', 'NOT IN' ;
valueExpr     = string | number | valueFunc ;
valueFunc     = geoPoint | instant | time | dateTime, localDateTime ;
geoPoint      =  '"' lat ',' lon '"' ;
instant       = 'instant(' string ')' ;
time          = 'time(' string ')' ;
dateTime      = 'dateTime(' string ')' ;
localDateTime = 'localDateTime(' string ')' ;

Examples:

user.myCategory = "articles"
user.myCategory IN ("articles", "documents")
user.myCategory != "articles"
user.myCategory LIKE "*tic*"
myPriority < 10
myPriority <= 10
myPriority > 10
myPriority < 100
myPriority != 10
myInstant = instant('2014-02-26T14:52:30.00Z')
myInstant <= instant('2014-02-26T14:52:30.00Z')
myInstant <= dateTime('2014-02-26T14:52:30.00+02:00')
myTime = time('09:00')
myLocalDateTime = time('2014-02-26T14:52:30.00')
myLocation = '59.9127300,10.7460900'
myLocation IN ('59.9127300,10.7460900','59.2181000,10.9298000')

logicalExpr

Grammar:

logicalExpr = constraintExpr operator constraintExpr ;
operator    = 'AND' | 'OR' ;

Examples:

myCategory = "articles" AND myPriority > 10
myCategory IN ("articles", "documents") OR myPriority <= 10

dynamicConstraint

Grammar:

dynamicConstraint = functionExpr ;

Examples:

fulltext('myCategory', 'Searching for fish', 'AND')
ngram('description', 'fish boat', 'AND')

notExpr

Grammar:

notExpr = 'NOT' constraintExpr ;

Examples:

NOT myCategory = 'article'

orderExpr

Grammar:

orderExpr = 'ORDER BY' ( fieldOrderExpr | dynamicOrderExpr )
            ( ',' ( fieldOrderExpr | dynamicOrderExpr ) )* ;

fieldOrderExpr

Grammar:

fieldOrderExpr = propertyPath [ direction ] ;
direction>     = 'ASC' | 'DESC' ;

Examples:

_name ASC
_timestamp DESC
title DESC
data.myProperty

dynamicOrderExpr

Grammar:

dynamicOrderExpr = functionExpr [ direction ] ;
direction        = 'ASC' | 'DESC' ;

Examples:

geoDistance('59.9127300,10.746090')

propertyPath

Grammar:

propertyPath = pathElement ( '.' pathElement )* ;
pathElement  = ( [ validJavaIdentifier - '.' ] )* ;

Examples:

myProperty
data.myProperty
data.myCategory.myProperty

Tip

Wildcards in propertyPaths are supported in functions fulltext and ngram only at the moment. When using these functions, expressions like this are valid:

myProp*
*Property
data.*
*.myProperty
data.*.myProperty

functionExpr

Grammar:

functionExpr = functionName '(' arguments ')' ;

Examples

Find all documents where property ‘myCategory’ is populated with a value, and the value does not equal ‘article’.

myCategory LIKE '*' AND NOT myCategory = 'article'

Release Notes

Enonic XP 6.12 is a minor release with exciting new features, improvements and fixes.

Multi-lingual Admin

6.11 opened up the possiblity of localizing admin and most phrases were translated to Norwegian to demonstrate this. 5 more translations have since been added, and the admin console may now be used in seven languages. The new ones are: French, Spanish, Portuguese, Russian and Swedish. The language used by Enonic XP to render the admin pages is based on the settings in your browser. If the language of your choice is not supported by XP, admin will default to English.

A special thanks goes to Paulo Vitor Merlo de Andrade, who contributed the Portuguese translation. Translations to other languages are greatly appreciated. Check out how to contribute here: Contributing to Translations.

Content and image selectors may browse tree structure

The content and image selectors have gained a “tree” icon on the left hand side. Clicking this icon will turn it blue, and the dropdown box with the available choices will switch to a tree structure, so it is possible to look up the content or image in a known location:

_images/image-selector-tree.png

The tree icon has been clicked, in order to look for images in a specific folder. Notice how the tree icon is blue.

Image Editor gets rotation and flip

In the image editor, images may now be rotated and flipped:

_images/image-editor-rotate.png

Just the click of a button to rotate an image 90°

_images/image-editor-flip.png

Another click of a button to flip the image around its vertical axis

Rewritten Users App

The Users App has been rewritten from scratch using GraphQL technology to improve performance. In the process, the User Interface have been improved. There are also two new features: Bulk delete and adding roles directly to groups.

_images/users-group-roles.png

Roles may be added to groups for much improved role management

_images/users-bulk-delete.png

Multiple users may now be deleted in one go

Vacuum tool

The toolbox has a great new tool to save disk space. The vacuum tool will go through the blob store and physically delete all object that is no longer in use.

Input types configuration

There are some additional ways to configure input types with boundaries that will be validated by Enonic XP.

  • Double and Long: max and min for boundaries on absolute values.
  • TextArea and TextLine: max-length to limit the number of characters.

Other improvements

  • More configuration options for the input types, TextArea, TextLine, Double and Long
  • Support for range header and byte serving for attachments
  • New sanitize function in JavaScript
  • Header shortcuts in HTML Area changed to “Ctrl-Shift-number”
  • Keyboard deletion of selected component in Page Editor and Page Component view
  • Checkbox column in content and image selectors right-aligned

50+ bugs fixed

Changelog

For a complete list of changes and bugfixes see http://github.com/enonic/xp/releases/tag/v6.12.0

Upgrade notes - 6.12

Warning

This documentation describes upgrading from 6.11.x to 6.12.

Note

Enonic XP 6.12 now requires minimum Java 1.8.92

Upgrade Steps

1. Backup the installation

Backup you current installation. This is described in Backup and Restore.

You could also do a dump of the system, but then you will lose versions if you have to reload it.

2. Install new version

Download Enonic XP http://repo.enonic.com/public/com/enonic/xp/distro/6.12.3/distro-6.12.3.zip and install according to your setup.

Tip

Remember to update any startup scripts you might have to launch your new installation given a server restart

3. Configure XP_HOME

The next step depends on your setup. Do you have your $XP_HOME folder outside or inside the $XP_INSTALL folder?

Outside the $XP_INSTALL - folder:

Make sure the new installation points to the correct $XP_HOME folder.

Inside the $XP_INSTALL - folder:

Copy your $OLD_XP_INSTALL/home folder to the the new $NEW_XP_INSTALL/ (on all nodes).

4. Stop the old installation

5. Start the new installation

6. Configure apps to build with 6.12

In 6.12 we have made several structural changes to Enonic XP. This affects how you build your own apps with Gradle.

The Gradle plugin for building Enonic applications are not included in the distribution anymore. This helps us improve the build tools without waiting for a new release of XP every time. Here is how to make build scripts work for 6.12.x:

Before you would probably have something like this in the beginning of your build.gradle file:

buildscript {
    plugins {
        repositories {
            mavenLocal()
            jcenter()
            maven {
                url 'http://repo.enonic.com/public'
            }
        }

        dependencies {
            classpath "com.enonic.xp:gradle-plugin:${xpVersion}"
        }
    }
}

apply plugin: 'com.enonic.xp.app'
...

Now you can write the same block as:

plugins {
    id 'com.enonic.xp.app' version '1.0.13'
}

PS: This requires Gradle 4.0 or later.

All the rest will be the same. You can look at https://github.com/enonic/starter-vanilla for an example of how to use plugin.

7. Admin UI config file is renamed

If you have used the Admin UI config-file in 6.11 (to disable the Welcome Tour), the name of that file has changed in 6.12. In order for XP to pick that up you will need to:

Rename the file com.enonic.xp.admin.ui.cfg in the $XP_HOME/config/ directory to $XP_HOME/config/com.enonic.xp.app.main.cfg. The settings in that file have not changed.

How is Enonic XP Licensed

Enonic XP is available under the GPL 3.0 license. This basically means that you are free to use and re-distribute Enonic XP according to the GPL license. The linking exception ensures that you can build custom applications and libraries on top of Enonic XP and license these however you see fit. Any changes made to the Enonic XP core platform however must be licensed as PGL.

We encourage the use of FOSS licensing for 3rd party apps and libraries. Libraries in particular should be licensed with a non-intrusive license such as Apache, BSD or MIT.

Note

This is a major difference from products such as Drupal and Wordpress where your themes, plugins and modules must be licensed as GPL too.

Enonic XP also consists of many 3rd party software components. The complete list can be found in our Notice.txt file

What is $XP_INSTALL?

$XP_INSTALL and $XP_HOME are referenced frequently in the documentation and it is important to understand the difference. $XP_INSTALL is the top level directory of the XP installation and it contains the directories bin, home, lib, toolbox and others.

What is $XP_HOME?

$XP_HOME, by default, is the location of the $XP_INSTALL/home folder which contains the config, deploy, repo and other directories specific to a single XP instance. The home folder can be copied to multiple locations for developers working on more than one project.

There are two situations where the $XP_HOME environment variable must be set:

  1. When developers are working on an application and intend to use ./gradlew deploy.
  2. When a home folder other than $XP_INSTALL/home is to be used.

Where can I get help?

The community forum would be a good place to start. We also offer formal training courses.

Enonic also offers software support subscriptions for business critical installations: https://enonic.com/pricing
