Using CDN

To include the ES6 Promise polyfill via CDN, add one of the following script tags to the HTML page (choose one of the provided variants):

<!-- Full (development) -->
<script src="https://cdn.jsdelivr.net/npm/es6-promise@4/dist/es6-promise.js"></script>
<script src="https://cdn.jsdelivr.net/npm/es6-promise@4/dist/es6-promise.auto.js"></script>

<!-- Minified (production) -->
<script src="https://cdn.jsdelivr.net/npm/es6-promise@4/dist/es6-promise.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/es6-promise@4/dist/es6-promise.auto.min.js"></script>

Include the polyfill before loading Syncfusion scripts so Promise is available when components initialize.

Node.js

To use the ES6 Promise polyfill in a Node.js environment:

Install:

npm install es6-promise
# or
yarn add es6-promise

Use in code:

var Promise = require('es6-promise').Promise;
