FAST Element

License: MIT npm version

The fast-element library is a lightweight means to easily build performant, memory-efficient, standards-compliant Web Components. FAST Elements work in every major browser and can be used in combination with any front-end framework or even without a framework.

Installation

From NPM

To install the fast-element library, use either npm or yarn as follows:

npm install --save @microsoft/fast-element
yarn add @microsoft/fast-element

Within your JavaScript or TypeScript code, you can then import library APIs like this:

import { FASTElement } from '@microsoft/fast-element';

:::tip Looking for a setup that integrates with a particular front-end framework or bundler? Check out our integration docs. :::

From CDN

A pre-bundled script that contains all APIs needed to build web components with FAST Element is available on CDN. You can use this script by adding type="module" to the script element and then importing from the CDN.

<!DOCTYPE html>
<html lang="en">
    <head>
        <script type="module">
          import { FASTElement } from "https://cdn.jsdelivr.net/npm/@microsoft/fast-element/dist/fast-element.min.js";

          // your code here
        </script>
    </head>
    <!-- ... -->
</html>

The markup above always references the latest release. When deploying to production, you will want to ship with a specific version. Here's an example of the markup for that:

<script type="module" src="https://cdn.jsdelivr.net/npm/@microsoft/fast-element@1.6.2/dist/fast-element.min.js"></script>

:::note For simplicity, examples throughout the documentation will assume the library has been installed from NPM, but you can always replace the import location with the CDN URL. :::
