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](https://github.com/inikulin/parse5) for parsing HTML and can optionally use the forgiving [htmlparser2](https://github.com/fb55/htmlparser2/). Cheerio can parse nearly any HTML or XML document. Cheerio works in both browser and server environments. ## API ### Loading 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. ```js // ES6 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> ``` ### Selectors Once you've loaded the HTML, you can use jQuery-style selectors to find elements within the document. #### \$( selector, [context], [root] ) `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. ```js $('.apple', '#fruits').text(); //=> Apple $('ul .pear').attr('class'); //=> pear $('li[class=orange]').html(); //=> Orange ``` ### Rendering When you're ready to render the document, you can call the `html` method on the "root" selection: ```js $.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`](https://developer.mozilla.org/en-US/docs/Web/API/Element/outerHTML) of a selection, you can use the `outerHTML` prop: ```js $('.pear').prop('outerHTML'); //=> <li class="pear">Pear</li> ``` You may also render the text content of a Cheerio object using the `text` method: ```js const $ = cheerio.load('This is <em>content</em>.'); $('body').text(); //=> This is content. ``` ### The "DOM Node" object Cheerio collections are made up of objects that bear some resemblance to [browser-based DOM nodes](https://developer.mozilla.org/en-US/docs/Web/API/Node). You can expect them to define the following properties: - `tagName` - `parentNode` - `previousSibling` - `nextSibling` - `nodeValue` - `firstChild` - `childNodes` - `lastChild` ## Screencasts [https://vimeo.com/31950192](https://vimeo.com/31950192) > This video tutorial is a follow-up to Nettut's "How to Scrape Web Pages with > Node.js and jQuery", using cheerio instead of JSDOM + jQuery. This video shows > how easy it is to use cheerio and how much faster cheerio is than JSDOM + > jQuery. ## Cheerio in the real world Are you using cheerio in production?

Special Thanks This library stands on the shoulders of some incredible developers. A special thanks to: **• @fb55 for htmlparser2 & css-select:** Felix has a knack for writing speedy parsing engines. He completely re-wrote both @tautologistic's `node-htmlparser` and @harry's `node-soupselect` from the ground up, making both of them much faster and more flexible. Cheerio would not be possible without his foundational work **• @jQuery team for jQuery:** The core API is the best of its class and despite dealing with all the browser inconsistencies the code base is extremely clean and easy to follow. Much of cheerio's implementation and documentation is from jQuery. Thanks guys. **• @tj:** The style, the structure, the open-source"-ness" of this library comes from studying TJ's style and using many of his libraries. This dude consistently pumps out high-quality libraries and has always been more than willing to help or answer questions. You rock TJ. ## License MIT
