AMP with AEM - Demonstrating the ability of Content Fragments in AEM


AMP integration with AEM - CaaS Model(Content as a service) demo 

I was receiving requests for writing sample code to showcase Third party AMP page which retrieve data from AEM (Content as a service).

What is AMP?

The AMP Project is an open-source Google-run website publishing technology initiative aiming to make the web better for all. The project enables the creation of websites and ads that are consistently fast, beautiful and high-performing across devices and distribution platforms. More details on https://www.ampproject.org/

How can I develop AMP websites?

You need to refer the above url for implementing AMP Projects, which has detailed information about syntax of AMP.

AMP integration with AEM

Step 1: To work with AMP and AEM, create an AMP file as shown below and deploy it on any server.
(You can refer PWA implementation & deployment article for the same: Set-up PWA running environment).

A sample AMP Structure is given below.

Save below file as 'Sample_AMP.html'


<!doctype html>
<html ⚡>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width,minimum-scale=1,initial-scale=1">
  <title>AMP demo with AEM</title>
  <link rel="canonical" href="index.html" />
  <script async src="https://cdn.ampproject.org/v0.js"></script>
  <script async custom-element="amp-list" src="https://cdn.ampproject.org/v0/amp-list-0.1.js"></script>
  <script async custom-template="amp-mustache" src="https://cdn.ampproject.org/v0/amp-mustache-0.2.js"></script>
  <style amp-boilerplate>body{-webkit-animation:-amp-start 8s steps(1,end) 0s 1 normal both;-moz-animation:-amp-start 8s steps(1,end) 0s 1 normal both;-ms-animation:-amp-start 8s steps(1,end) 0s 1 normal both;animation:-amp-start 8s steps(1,end) 0s 1 normal both}@-webkit-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@-moz-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@-ms-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@-o-keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}@keyframes -amp-start{from{visibility:hidden}to{visibility:visible}}</style>
  <noscript>
         <style amp-boilerplate>body{-webkit-animation:none;-moz-animation:none;-ms-animation:none;animation:none}</style>
  </noscript>
</head>
<body>
<amp-list width="auto"
  height="100"
  layout="fixed-height" src="test.json">
  <template type="amp-mustache">
    <div class="url-entry">
      <a href="{{url}}">{{title}}</a>
    </div>
  </template>
</amp-list> 
</body>
</html>

It takes a JSON input file(src="test.json") and publish data on page.


Step 2: Author a content fragment in AEM which has JSON format as below.
Follow this link for Creating & Authoring Content Fragments:  Create & Author Content Fragments in AEM

{
 "items": [
   {
     "title": "AMP YouTube",
     "url": "https://www.youtube.com/"
   },
   {
     "title": "AMPproject.org",
     "url": "https://www.ampproject.org/"
   },
   {
     "title": "AEM Tutorial Blog",
     "url": "http://aem-cq-tutorials.blogspot.com/"
   },
   {
     "title": "Solr with AEM Totorial",
     "url": "http://aemsolr.blogspot.in/"
   }
 ]
}


Step 3: Now, update the 'Sample_AMP.html' for src="test.json"with publish url of content fragment authored page


Step 4: Ensure CORS is enabled in AEM. (Confused? Refer https://aem-cq-tutorials.blogspot.com/2018/12/integrate-pwa-aem-and-retrieve-aem.html to updated CORS)

Step 5: Now invoke the AMP file, from server, you can see that data is appearing as shown below.

*(I haven't done styling just Functionality is tested).

Notes:
AMP - uses specific tags and syntax which needs to be validated after each change in code. You can use online AMP validator(https://validator.ampproject.org/) for this purpose.
