# 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](http://api.jquery.com/).
|
||
|
|
For source files and issues, please visit the [jQuery repo](https://github.com/jquery/jquery).

## Including jQuery
|
||
|
|
|
||
|
|
Below are some of the most common ways to include jQuery.
|
||
|
|
|
||
|
|
### Browser
|
||
|
|
|
||
|
|
#### Script tag
|
||
|
|
|
||
|
|
```html
|
||
|
|
<script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Babel
|
||
|
|
|
||
|
|
[Babel](http://babeljs.io/) is a next generation JavaScript compiler. One of the features is the ability to use ES6/ES2015 modules now, even though browsers do not yet support this feature natively.
|
||
|
|
|
||
|
|
```js
|
||
|
|
import $ from "jquery";
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Browserify/Webpack
|
||
|
|
|
||
|
|
There are several ways to use [Browserify](http://browserify.org/) and [Webpack](https://webpack.github.io/). For more information on using these tools, please refer to the corresponding project's documention. In the script, including jQuery will usually look like this...
|
||
|
|
|
||
|
|
```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](http://requirejs.org/docs/whyamd.html).
|
||
|
|
|
||
|
|
```js
|
||
|
|
define(["jquery"], function($) {
|
||
|
|
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
### Node
|
||
|
|
|
||
|
|
To include jQuery in [Node](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/tmpvar/jsdom). This can be useful for testing purposes.
|
||
|
|
|
||
|
|
```js
|
||
|
|
require("jsdom").env("", function(err, window) {
|
||
|
|
if (err) {
|
||
|
|
console.error(err);
|
||
|
|
return;
|
||
|
|
}
|
||
|
|
|
||
|
|
var $ = require("jquery")(window);
|
||
|
|
});
|
||
|
|
```
|
