Root node Puppeteer communicates with the browser by using dev tools.

As shown in the below diagram, faded entities are not currently represented in the Puppeteer framework. Let’s see the browser architecture of Puppeteer. It follows the latest maintenance LTS version of the Node framework.

Puppeteer-core is a lightweight version of Puppeteer for launching your scripts in an existing browser or for connecting it to a remote one. Since the launch developers have published two versions Puppeteer and Puppeteer-core. Create a server-side rendered version of the application.It runs headless by default but can be changed to run full (non-headless).

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