1 # jQuery 2 3 > jQuery is a fast, small, and feature-rich JavaScript library. 4 5 For information on how to get started and how to use jQuery, please see [jQuery's documentation](https://api.jquery.com/). 6 For source files and issues, please visit the [jQuery repo](https://github.com/jquery/jquery). 7 8 If upgrading, please see the [blog post for 3.7.1](https://blog.jquery.com/2023/08/28/jquery-3-7-1-released-reliable-table-row-dimensions/). This includes notable differences from the previous version and a more readable changelog. 9 10 ## Including jQuery 11 12 Below are some of the most common ways to include jQuery. 13 14 ### Browser 15 16 #### Script tag 17 18 ```html 19 <script src="https://code.jquery.com/jquery-3.7.1.min.js"></script> 20 ``` 21 22 #### Webpack / Browserify / Babel 23 24 There are several ways to use [Webpack](https://webpack.js.org/), [Browserify](http://browserify.org/) or [Babel](https://babeljs.io/). For more information on using these tools, please refer to the corresponding project's documentation. In the script, including jQuery will usually look like this: 25 26 ```js 27 import $ from "jquery"; 28 ``` 29 30 If you need to use jQuery in a file that's not an ECMAScript module, you can use the CommonJS syntax: 31 32 ```js 33 var $ = require( "jquery" ); 34 ``` 35 36 #### AMD (Asynchronous Module Definition) 37 38 AMD is a module format built for the browser. For more information, we recommend [require.js' documentation](https://requirejs.org/docs/whyamd.html). 39 40 ```js 41 define( [ "jquery" ], function( $ ) { 42 43 } ); 44 ``` 45 46 ### Node 47 48 To include jQuery in [Node](https://nodejs.org/), first install with npm. 49 50 ```sh 51 npm install jquery 52 ``` 53 54 For jQuery to work in Node, a window with a document is required. Since no such window exists natively in Node, one can be mocked by tools such as [jsdom](https://github.com/jsdom/jsdom). This can be useful for testing purposes. 55 56 ```js 57 const { JSDOM } = require( "jsdom" ); 58 const { window } = new JSDOM( "" ); 59 const $ = require( "jquery" )( window ); 60 ```
