A Web Scraper as defined by me is an Automation Process that helps in fetching Contents From The Web by simulating HTTP HEADERS and HTTP VERBS. Well, that’s the introduction to Node.js, let’s talk about Scrapers. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. Node.js is a platform built on Chrome’s JavaScript runtime for easily building fast and scalable network applications. But the one that meets the eye most happens to be Node.js. I personally think Javascript has the most framework. It has a whole lot of frameworks under it. Javascript is perfect for a lot of things, I mean there is so much one can do with the technology. Why Would You Want To Build A Web Scraper Well, let’s get to that in the next line. But before we begin, I am sure you’d like to know why you’d want to build a Web Scraper in the first place.

However, in this lesson, I will teach you how to build a Web Scraper with Node.js using the request method and Google Puppeteer.
You can read about that on How To Build A CLI App Using Node.js. There is a lot you can do with the technology and I spoke about How To Build A CLI App Using Node.js in one lecture. Node.js is a very powerful technology to have under one’s belt. Node.js is a javascript runtime built on chrome’s v8 engine.
