This dude consistently pumps out high-quality libraries and has always been more than willing to help or answer questions. style, the structure, the open-source"-ness" of this library comes from studying TJ's style and using many of his libraries.Much of cheerio's implementation and documentation is from 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. 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 will download the development packages and run the test suite. To run the test suite, download the repository, then within the cheerio directory, run: These are some of the contributors that have made cheerio possible: project : cheerioĪre you using cheerio in production? Add it to the wiki! Testing 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: logHtml ( ) // logs "Hello, world!" to the console The "DOM Node" objectĬheerio collections are made up of objects that bear some resemblence to browser-based DOM nodes. Looking for a career upgrade? Check out the available Node.js & Javascript positions at these innovative companies: If your use case requires any of this functionality, you should consider projects like PhantomJS or JSDom. Specifically, it does not produce a visual rendering, apply CSS, load external resources, or execute JavaScript. 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. Preliminary end-to-end benchmarks suggest that cheerio is about 8x faster than JSDOM.Ĭheerio wraps around parse5 parser and can optionally use forgiving htmlparser2. As a result parsing, manipulating, and rendering are incredibly efficient. 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. Cheerio implements a subset of core jQuery.
