Puppeteer is a powerful Node.js library developed by Google that provides a high-level API to control headless Chrome or Chromium over the DevTools Protocol. It is widely used for web scraping, automated testing, creating screenshots, generating PDFs, and more. In this blog post, we'll dive into what Puppeteer is, how to set it up in your Node.js environment, and explore some practical use cases with code examples.

 

What is Puppeteer?

Puppeteer is essentially a tool that allows you to programmatically control a web browser. By using Puppeteer, you can automate tasks like:

• Navigating to web pages
• Filling out and submitting forms
• Capturing screenshots and PDFs
• Scraping data from websites
• Running automated tests

Since Puppeteer operates on a headless browser by default (a browser without a graphical user interface), it can perform these tasks quickly and efficiently.

Setting Up Puppeteer

Before you can start using Puppeteer, you need to have Node.js installed on your system. You can download and install Node.js from nodejs.org.

Once Node.js is installed, you can set up a new project and install Puppeteer via npm:
