Google AMP amp-mustache

Last Updated : 25 Oct, 2020

We use amp-mustache to render Mustache templates. The amp-mustache does not provide the JSON data they are collected by amp-list, amp-access or amp-form component.

Example of a JSON file passed with a dictionary using amp-list.

Javascript

{ 
  "geeksforgeeks": [ 
    { 
      "fullname": "geeksforgeeks", 
      "phonenumber": "9999999999", 
    } 
  ] 
}

Required Script: Importing the amp-mustache component into the header.

HTML

<script async custom-template="amp-mustache" src= 
"https://cdn.ampproject.org/v0/amp-mustache-0.2.js"> 
</script>

The amp-mustache is used with components like amp-list or amp-form to pass a JSON file (example given after introduction).

Importing amp-list component into the header.

HTML

<script async custom-element="amp-list" src= 
"https://cdn.ampproject.org/v0/amp-list-0.1.js"> 
</script>

Importing amp-list component into the header.

HTML

<script async custom-element="amp-form" src= 
"https://cdn.ampproject.org/v0/amp-form-0.1.js"> 
</script>

Validation: The amp-mustache is needed to be in well framed DOM fragments. So we can’t use amp-mustache for:

Calculate tag name eg <{{tagName}}>
Calculate attribute name <div {{attrName}}=attr>

These are not allowed

Example:

HTML

<!doctype html>

    <meta charset="utf-8">
