Npm cheerio code#
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. Cheerio would not be possible without his foundational work He completely re-wrote both node-htmlparser and node-soupselect from the ground up, making both of them much faster and more flexible. A special thanks to:įelix has a knack for writing speedy parsing engines. This library stands on the shoulders of some incredible developers.

This video shows how easy it is to use cheerio and how much faster cheerio is than JSDOM + jQuery. 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. You can expect them to define the following properties: The "DOM Node" objectĬheerio collections are made up of objects that bear some resemblance to browser-based DOM nodes.

If your use case requires any of this functionality, you should consider browser automation software like Puppeteer and Playwright or DOM emulation projects like JSDom. This makes Cheerio much, much faster than other solutions. Specifically, it does not produce a visual rendering, apply CSS, load external resources, or execute JavaScript which is common for a SPA (single page application). It does not interpret the result as a web browser does. Cheerio is not a web browserĬheerio parses markup and provides an API for traversing/manipulating the resulting data structure. Cheerio can parse nearly any HTML or XML document. As a result parsing, manipulating, and rendering are incredibly efficient.Ĭheerio wraps around parse5 parser and can optionally use forgiving htmlparser2. Cheerio removes all the DOM inconsistencies and browser cruft from the jQuery library, revealing its truly gorgeous API.Ĭheerio works with a very simple, consistent DOM model. InstallationĬheerio implements a subset of core jQuery. The source code for the last published version, 0.22.0, can be found here. We are currently working on the 1.0.0 release of cheerio on the main branch. load(): const $ = cheerio.load('.Const cheerio = require ( 'cheerio' ) const $ = cheerio. If you need to modify parsing options for XML input, you may pass an extra Optionally, you can also load in the HTML by passing the string as the context: $('ul', '.') const $ = cheerio.load('.', null, false) You can set load's third argument to false to disable this. Similar to web browser contexts, load will introduce, , and elements if they are not already present. This is the preferred method: // ES6 or TypeScript: With Cheerio, we need to pass in the HTML document. This step in jQuery is implicit, since jQuery operates on the one, baked-in DOM. Loadingįirst you need to load in the HTML. This is the HTML markup we will be using in all of the API examples.
