Integrating the AngularJS Framework into AEM HTL

Integrating the AngularJS Framework into AEM HTL(Sightly) with working example.

I have seen many webpages with similar topic, but complex while we try to replicate it in our local environment. Some times they dont work or quite tough to make it work. Here I am going to take you through an easy Angular JS integration with Sightly.

Note: Please ensure you verify the angular syntax using any online tool when you update the code, because angular is strict on syntax.

What is angular JS?
Angular JS is a JavaScript library that simplifies the creation of powerful components, by extending HTML vocabulary for your application.

Why Angular JS with AEM HTL?
Angular JS is the current trend. When we need to declare dynamic views in web applications to make it extra ordinary powerful, we need Angular JS.

What is the aim of this sample?
Through this demo, you will know how to create a simple angular JS Component which performs below tasks,

  1.  - Takes user iput and diplay through angular JS tags
  2.  - Takes user click and show an element using angular JS
  3.  - User click invokes a backend WCMUse Java file and displays the data through HTL + Angular JS

Steps involved in developing AEM + Angular + HTL Component.

Create a template
    Create a new template as shown below at /apps/htl/templates

Create a folder 'page' at /apps/htl/components
Create a new component at /apps/htl/components/page as shown below

Update the 'templateHTL.jsp' file content at /apps/htl/components/page/templateHTL/templateHTL.jsp with below code.
    <%@include file="/libs/foundation/global.jsp" %>
    <cq:include script="/libs/wcm/core/components/init/init.jsp"/>
    <h1>Here is your Angular HTL Component</h1>
    <cq:include path="par" resourceType="foundation/components/parsys" />

Create and render component that uses the template
    Create a component as shown below


Go to path /apps/htl/components/angular/angular.html and modify the 'angular.html' with below code
     <div ng-app>
            <p>Enter a value: <input type="text" ng-model="name">
            <p ng-bind="name"></p>
             <div ng-view></div>
            <ul class="menu">
                <li><a ng-click="currentTpl1='/tpl1.html'">Template Load example</a>
                <li><a ng-click="currentTpl1='/tpl2.html'">Show the list of cars</a>
           <div ng-view></div>
            <div id="tpl-content"> <ng-include src="currentTpl1"> </ng-include> </div>
            <script type="text/ng-template" id="/tpl1.html">
                <p> First name: <input type="text" ng-model="firstname"/>
                    Last name: <input type="text" ng-model="lastname"/>
                    <p>First name:<p ng-bind="firstname"></p>
                    <p>Last name:<p ng-bind="lastname"></p>
            <script type="text/ng-template" id="/tpl2.html"  data-sly-include="template.html">

            </script >
Create a 'template.html' at path /apps/htl/components/angular

    <div data-sly-use.vehicleService="com.aem.VehicleService" >
      <div data-sly-use.myClass="com.aem.VehicleService" data-sly-unwrap>
        <ul data-sly-list.keyName="${myClass.getVehicleDetails}">

Create a dialog (create dialog option) at path /apps/htl/components/angular with label 'dialog'

Client Library Creation for AngularJS framework
  •     Create a folder 'clientlibs' at /apps/htl/components/angular and Add below two properties to it.
    (name:categories,    Type:String[],     value:cq.widget)
    (name:dependencies, Type:String[],     value:angularjs)

  •     Download the latest 'angular.min.js' from angular JS Site
  •     Create a file 'angular.min.js' in folder /apps/htl/components/angular/clientlibs; copy paste the downloaded angular.min.js content to this file.
  •   Now you have angular JS at your crx in location /apps/htl/components/angular/clientlibs/angular.min.js
  •     Create a new file js.txt at /apps/htl/components/angular/clientlibs; open the file 'js.txt' and paste 'angular.min.js' (without quotes) and save it.
  •     Now you have a new client library for angular JS. 
  •     Add this in your page , open file /apps/htl/components/page/templateHTL/templateHTL.jsp andadd new client library to it by adding line
    <cq:includeClientLib categories="cq.widgets" />

The Folder Structure Now

Create a WCMUse class for data.
    We are creating a map with set of vehicles and populating it using HTL.

    The VehicleService.Java WCMUse class below, build and deploy it using maven to your AEM.

Please find the WCMUse class here. VehicleService.JAVA

Create a page that uses AngularJS functionality; Code execution

    Open site admin and create a page with template 'templateHTL'. Open it in edit mode.
    Drag and drop the 'angular' component to the newly created page.

    Once you re load the page and start entering anything at 'Enter a Value', you can see the inline option working through angular.

    Code executed:  <p ng-bind="name"></p>

    When you click on 'Template Load example', you can see the new templates on bottom.

    Code executed:

    'On Click' is added at line,
    <li><a ng-click="currentTpl1='/tpl1.html'">Template Load example</a>

    A template place holder is at line,
    <div id="tpl-content"> <ng-include src="currentTpl1"> </ng-include> </div>

    Script executed when the teplate got clicked,

     <script type="text/ng-template" id="/tpl1.html">
                <p> First name: <input type="text" ng-model="firstname"/>
                    Last name: <input type="text" ng-model="lastname"/>
                    <p>First name:<p ng-bind="firstname"></p>
                    <p>Last name:<p ng-bind="lastname"></p>
     You can also see, on entering first name and second name, again inline in action.

     When you clicked on 'Show the list of cars'
     We have the Data coming from WCMUse class now as shown below.

     Code executed
     'On Click' is added at line,
     <li><a ng-click="currentTpl1='/tpl2.html'">Show the list of cars</a>
     A template place holder is at line,
     <div id="tpl-content"> <ng-include src="currentTpl1"> </ng-include> </div>
     Which in turn calls the script for template selection from
     <script type="text/ng-template" id="/tpl2.html"  data-sly-include="template.html">

      </script >
     This executes the template.html at path /apps/htl/components/angular/template.html

     The template.html executes the WCMUse class and process the data from below code.
    <div data-sly-use.vehicleService="com.aem.VehicleService" >
      <div data-sly-use.myClass="com.aem.VehicleService" data-sly-unwrap>
        <ul data-sly-list.keyName="${myClass.getVehicleDetails}">

Want the code package?
    Please let me know through e-mail if you need the package.

Search  Enhancements
Search enables navigating within the product and search all areas of the product. Prior to 6.2, Adobe
had invested in search capabilities with integrations to SOLR as well as a faceted search user interface in 6.0 and 6.1, but the comprehensive search capabilities provided in 6.2 will surely be most preferred by customers.

Content Fragments
Content creators can now use the power of assets and its referencing capabilities across multiple devices along with variations. The new content fragment section allows content fragments metadata to be created the same way how an asset metadata schema can be created using the Schema Editor.

Template Editor
AEM 6.2 provides set of built in templates. This helps authors to create templates immediately with a set of templates and components developed already. The core features allow content authors to insert components along with initial sets of content to create a structure for it to be leveraged to create pages under Sites. This also provides a user interface for content authors to leverage the Design view of the editor to preview what the template would like on other devices such as ipad and mobile

Asset insights
Assets Insights is a new and interesting feature in AEM 6.2 that allows assets usage to be tracked
across various channels such as websites, email campaigns, mobile devices, etc. Adobe Analytics enables the tracking functionality. The statistics that can be captured are items such as what assets have been downloaded, clicked on, conversion rates and other digital marketing trends, which helps the atuthor to add meta data more effectively.

Sightly/ HTL Tips

 Sightly Tips

For SIghtly Tutorial Visit our help page :

? Sightly comparing a string value
Say we have a string 'heroType' and having some values. We need to test its value to 'AL', we can use below code to compare it.

<div data-sly-test="${style.getHeroType == 'AL' }">Hello</div>

? Check a list's(formatList) size using below code
<sly data-sly-test.emptysize ="${subcategoryUse.formatList.size > 0 }" />

--------------Similar Posts:----------

? Check a list item count is greater than zero in sightly
Java List : shopList; Use class : subcategoryUse

<sly data-sly-list.listItem="${subcategoryUse.shopList}">
 <sly data-sly-test.count="${listItemList.index > 0}">
 //Do your task here if count is more than zero

? Passing a value to Use  class from sightly:
 <sly    data-sly-use.integerUse="${'com.....IntegerUse' @ text=item}">

 And in Use class read it as,
 String text = get("text", String.class);

 ? Iterating over a list
 Java List: firstList

 <sly data-sly-list="${quantumUse.firstList}">
 //Use list item here using '{item}'

 ? When a Java list contains an object holding multiple values, each value can be retrieved as below
 <a x-cq-linkchecker="valid" href="${listItem.getUrl}.html"><img src="${listItem.getitemImage}" class="image-responsive"></a>
 <p>${listItem.getpriceInteger} <span>${listItem.getpriceDecimal}</span>

 ? Test multiple items in sightly

 <sly data-sly-test="${listItem.selectLogo && listItem.displayLogo}">
<div data-sly-test="${listItem.selectCategoryBadge.length > 0 && listItem.displayCategoryBadge}"

Integrate DOJO developed website with AEM

Integrate AEM With DOJO

Using DOJO as AEM Front end

There are some cases where AEM needs to be integrated with DOJO.

What is DOJO
DOJO is a Javascript framework used to develop interactive, responsive websites, and mainly used as a UI tool.

DOJO can be integrated with AEM through an interaction Layer. AEM exposes many of the methods to integrate with any third-party applications. This enables applications to work seamlessly when integrated. A JSON layer is used to integrate AEM with DOJO in this analysis.

DOJO with AEM - Arch view
The architectural diagram is shown below.

OSGi (Open Service Gateway Initiative) is the Java framework which runs on AEM and generates the JSON Layer. The generated JSON layer is used to interact with DOJO application.

Once the component is saved, OSGI runs in AEM which helps to generate a JSON. A Java service used to generate OSGI Bundles needs to be created to generate JSON from the authored component.
Any format of JSON can be generated as per DOJO requirement here. A sample JSON response is given below.


Steps to integrate DOJO with AEM:

We need to move all DOJO Libraries to AEM.
DOJO related components and templates to be moved to respective folder of AEM.
The page level items are split into templates and components. Same DOJO structure needs to be replicated in AEM, where in page will be divided into header, body, footer components. Content section can hold any levels of other components. The page structure in AEM is shown below.

Any impact on AEM Project Maintenance with respect to DOJO
New versions of AEM are available so often. Upgrades can be done without much challenges since the front end is separated from backend.
