LetвЂ™s start our Puppeteer tutorial with a basic example. Okay, now that we are all set and configured, let the fun begin! Using Puppeteer API for Automated Web Scraping

Note: This might take a while as Puppeteer will need to download and install Chromium in the background. Run this command in your project root directory: npm i puppeteer -save IвЂ™d recommend installing Puppeteer with npm, as itвЂ™ll also include the stable up-to-date Chromium version that is guaranteed to work with the library. Just to be safe, try to install those: sudo apt-get install -yq -no-install-recommends libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 libnss3 YouвЂ™ll also need some packages that may or may not be available on your system. You can install it here, or if you are CLI lover like me and like to work on Ubuntu, follow those commands: curl -sL | sudo -E bash.

ItвЂ™s maintained by the Chrome DevTools team and an awesome open-source community.Д®nough talking-letвЂ™s jump into the code and explore the world of how to automate web scraping using PuppeteerвЂ™s headless browsing! Preparing the EnvironmentДЇirst of all, youвЂ™ll need to have Node.js 8+ installed on your machine. What exactly is Puppeteer? ItвЂ™s a Node.js library which provides a high-level API to control headless Chrome or Chromium or to interact with the DevTools protocol. EditorвЂ™s note: ItвЂ™s worth mentioning IntoliвЂ™s Remote Browser, another new player, but that will have to be a subject for another article. But today weвЂ™ll be exploring headless Chrome via Puppeteer, as itвЂ™s a relatively newer player, released at the start of 2018. There are many web scraping tools that can be used for headless browsing, like Zombie.js or headless Firefox using Selenium. Instead of interacting with visual elements the way you normally would-for example with a mouse or touch device-you automate use cases with a command-line interface (CLI). Headless? Excuse me? Yes, this just means thereвЂ™s no graphical user interface (GUI). Now, what if we could leverage this functionality for our scraping needs and had a way to control browsers programmatically? ThatвЂ™s exactly where headless browser automation steps in!

Now, this is a problem if we are doing some kind of web scraping or web automation because more times than not, the content that weвЂ™d like to see or scrape is actually rendered by JavaScript code and is not accessible from the raw HTML response that the server delivers.ДЄs we mentioned above, browsers do know how to process the JavaScript and render beautiful web pages. The server returns JavaScript files or scripts injected into an HTML response, and the browser processes it. In other words, nowadays JavaScript rules the web, including almost everything you interact with on websites.ДЇor our purposes, JavaScript is a client-side language. Now there are much more interactive web apps with beautiful UIs, which are often built with frameworks such as Angular or React.

The last few years have seen the web evolve from simplistic websites built with bare HTML and CSS. What Is a Headless Browser and Why Is It Needed? In this article, weвЂ™ll see how easy it is to perform web scraping (web automation) with the somewhat non-traditional method of using a headless browser.
