# FAST Element [![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT) [![npm version](https://badge.fury.io/js/%40microsoft%2Ffast-element.svg)](https://badge.fury.io/js/%40microsoft%2Ffast-element) 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: ```shell npm install --save @microsoft/fast-element ``` ```shell yarn add @microsoft/fast-element ``` Within your JavaScript or TypeScript code, you can then import library APIs like this: ```ts 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](../integrations/introduction.md). ::: ### 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"`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules) to the script element and then importing from the CDN. ```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: ```html ``` :::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. ::: :::tip Looking for a quick guide on building components?
