Node.js has become immensely popular over the years as an essential part of many software development projects.

It was first released in 2009 by Ryan Dahl who was one of its original contributors (with some help from Douglas Crockford). Node.js is an open-source JavaScript runtime built on Chrome's V8 engine that runs on Linux, Mac OS X, and Windows operating systems. Puppeteer uses the WebDriver protocol to connect with the browser and simulate user interaction with HTML elements or pages. With it, you can run tests in the browser and then see the results in real-time on your terminal. Puppeteer lets you automate the testing of your web applications.

It is a tool for automating testing in your application using headless Chrome or Chromebit devices, without requiring any browser extensions like Selenium Webdriver or PhantomJS. Puppeteer is a Node.js library developed by Google that lets you control headless Chrome through the DevTools Protocol.

You create an instance of Browser, open pages, and then manipulate them with Puppeteer's API.Įxample: navigating to and saving a screenshot as example.png: Puppeteer will be familiar to people using other browser testing frameworks. All examples below use async/await which is only supported in Node v7.6.0 or greater. Starting from v3.0.0 Puppeteer starts to rely on Node 10.18.1+.

Prior to v1.18.1, Puppeteer required at least Node v6.4.0.
