import * as cheerio from 'cheerio';
const $ = cheerio.load('<h2 class="title">Hello world</h2>');
$('h2.title').text('Hello there!');
$('h2').addClass('welcome');
$.html();
//=> <html><head></head><body><h2 class="title welcome">Hello there!</h2></body></html>
Install Cheerio using a package manager like npm, yarn, or bun.
npm install cheerio
# or
bun add cheerio
❤ Proven syntax: Cheerio implements a subset of core jQuery. Cheerio removes all the DOM inconsistencies and browser cruft from the jQuery library, revealing its truly gorgeous API.
ϟ Blazingly fast: Cheerio works with a very simple, consistent DOM model. As a result parsing, manipulating, and rendering are incredibly efficient.
❁ Incredibly flexible: Cheerio wraps around parse5 for parsing HTML and can optionally use the forgiving htmlparser2. Cheerio can parse nearly any HTML or XML document. Cheerio works in both browser and server environments.
First you need to load in the HTML. This step in jQuery is implicit, since jQuery operates on the one, baked-in DOM. With Cheerio, we need to pass in the HTML document.
// ESM or TypeScript:
import * as cheerio from 'cheerio';
// In other environments:
const cheerio = require('cheerio');
const $ = cheerio.load('<ul id="fruits">...</ul>');
$.html();
//=> <html><head></head><body><ul id="fruits">...</ul></body></html>
Once you've loaded the HTML, you can use jQuery-style selectors to find elements within the document.
selector searches within the context scope which searches within the root
scope. selector and context can be a string expression, DOM Element, array
of DOM elements, or cheerio object. root, if provided, is typically the HTML
document string.
This selector method is the starting point for traversing and manipulating the document. Like in jQuery, it's the primary method for selecting elements in the document.
$('.apple', '#fruits').text();
//=> Apple
$('ul .pear').attr('class');
//=> pear
$('li[class=orange]').html();
//=> Orange
When you're ready to render the document, you can call the html method on the
"root" selection:
$.root().html();
//=> <html>
// <head></head>
// <body>
// <ul id="fruits">
// <li class="apple">Apple</li>
// <li class="orange">Orange</li>
// <li class="pear">Pear</li>
// </ul>
// </body>
// </html>
If you want to render the
outerHTML
of a selection, you can use the outerHTML prop:
$('.pear').prop('outerHTML');
//=> <li class="pear">Pear</li>
You may also render the text content of a Cheerio object using the text
method:
const $ = cheerio.load('This is <em>content</em>.');
$('body').text();
//=> This is content.
Cheerio collections are made up of objects that bear some resemblance to browser-based DOM nodes. You can expect them to define the following properties:

This video shows how easy it is to use cheerio and how much faster cheerio is than JSDOM + jQuery.
