![]() ![]() Although in small projects we won’t notice, in large scraping tasks it will become a big time saver. Because Cheerio doesn’t render the website like a browser (it doesn’t apply CSS or load external resources), Cheerio is lightweight and fast. However, Cheerio is well known for its speed. To select elements, we can use CSS and XPath selectors, making navigating the DOM easier. ![]() What is Cheerio?Ĭheerio is a Node.js framework that parses raw HTML and XML data and provides a consistent DOM model to help us traverse and manipulate the result data structure. Now that you have a big picture vision, let’s dive deeper into what each library has to offer and how you can use them to extract alternative data from the web. Puppeteer can take screenshots, submit forms and make PDFs.Cheerio makes extracting data super simple using JQuery like syntax and CSS/XPath selectors to navigate the DOM.Compared to Cheerio, Puppeteer is quite slow.Cheerio is lightning fast in comparison to Puppeteer.It has a steep learning curve as it has more functionalities and requires Async for better results.It has an easy learning curve thanks to its simple syntax.Puppeteer can interact with websites, accessing content behind login forms and scripts.Cheerio can’t interact with the site or access content behind scripts. ![]() It can execute Javascript, making it able to scrape dynamic pages like single-page applications (SPAs).It’s a DOM parser, able to parser HTML and XML files.Puppeteer was designed for browser automation and testing.Cheerio was built with web scraping in mind.However, they have major differences that you need to consider before picking a tool for your project.īefore moving into the details for each library, here’s an overview comparison between Cheerio and Puppeteer: Cheerio This tutorial has provided an in-depth guide on how to get started using Cheerio in a real-life project.įor further reference, you can also check out the FeatRocket source code on GitHub.Cheerio vs Puppeteer: Differences and When to Use ThemĬheerio and Puppeteer are both libraries made for Node.js (a backend runtime environment for Javascript) that can be used for scraping the web. Now, if we run node scrapper.js, you should see an output that looks like the below in your console:Ĭheerio is an excellent framework for manipulating and scraping markup contents on the server-side, plus it is lightweight and implements a familiar syntax. catch((err) => console.log("Fetch error " + err)) To get started, we need to run the npm init -y command, which will generate a new package.json file with its contents like below: `) Familiarity working with the command line and text editorsĬheerio can be used on any ES6+, TypeScript, and Node.js project, but for this article, we will focus on Node.js.Basic familiarity with HTML, CSS, and the DOM.To complete this tutorial, you will need: Building a sample application (FeatRocket) that scrapes LogRocket featured articles and logs them to the console. ![]()
