# jQuery
|
|
|
|
> jQuery is a fast, small, and feature-rich JavaScript library.
|
|
|
|
For information on how to get started and how to use jQuery, please see [jQuery's documentation](https://api.jquery.com/).
|
|
For source files and issues, please visit the [jQuery repo](https://github.com/jquery/jquery).
|
|
|
|
If upgrading, please see the [blog post for 3.6.4](https://blog.jquery.com/2023/03/06/jquery-3-6-4-released-selector-forgiveness/). This includes notable differences from the previous version and a more readable changelog.

## Including jQuery
|
|
|
|
Below are some of the most common ways to include jQuery.
|
|
|
|
### Browser
|
|
|
|
#### Script tag
|
|
|
|
```html
|
|
<script src="https://code.jquery.com/jquery-3.6.4.min.js"></script>
|
|
```
|
|
|
|
#### Webpack / Browserify / Babel
|
|
|
|
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:
|
|
|
|
```js
|
|
import $ from "jquery";
|
|
```
|
|
|
|
If you need to use jQuery in a file that's not an ECMAScript module, you can use the CommonJS syntax:
|
|
|
|
```js
|
|
var $ = require( "jquery" );
|
|
```
|
|
|
|
#### AMD (Asynchronous Module Definition)
|
|
|
|
AMD is a module format built for the browser. For more information, we recommend [require.js' documentation](https://requirejs.org/docs/whyamd.html).
|
|
|
|
```js
|
|
define( [ "jquery" ], function( $ ) {
|
|
|
|
} );
|
|
```
|
|
|
|
### Node
|
|
|
|
To include jQuery in [Node](https://nodejs.org/), first install with npm.
|
|
|
|
```sh
|
|
npm install jquery
|
|
```
|
|
|
|
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.
|
|
|
|
```js
|
|
const { JSDOM } = require( "jsdom" );
|
|
const { window } = new JSDOM( "" );
|
|
const $ = require( "jquery" )( window );
|
|
```
