How To Scrape Websites Using Puppeteer & Node.js

Web scraping is the process of extracting information from the internet, now the intention behind this can be research, education, business, analysis, and others. Basic web scraping script consists of a “crawler” that goes to the internet, surf around the web, and scrape information from given pages. We have gone over different web scraping tools by using programming languages and without programming like selenium, request, BeautifulSoup, MechanicalSoup, Parsehub, Diffbot, etc. It makes sense why everyone needs web scraping because it makes manual- data gathering processes very fast. And web scraping is the only solution when websites do not provide an API and data is needed. In this demonstration, we are going to use Puppeteer and Node.js to build our web scraping tool. Node.js is an open-source server runtime environment that runs on various platforms like Windows, Linux, Mac OS X, etc. It is not a programming language. It uses JavaScript language as the main programming interface. It is free and capable of reading and writing files on a server and used in networking. Puppeteer is a Node library that provides a high-level API to control Chromium or Chrome browser over the DevTools Protocol. It runs headless by default but can be changed to run full (non-headless). It is built by Google.
