There are 2 main Node.js libraries to pay close attention to when extracting information: axios and cheerio. The first one is an HTTP client created with special computing techniques in mind. It works perfectly with both a browser and Node.js. The latter represents a jQuery library for a server and makes it no sweat to deal with consistent DOM (Document Object Model) elements.
- Set up the development environment and fetch. Download Node.js and create an index.js file where you need to put your project name, description, and other details. A server.js file is best for writing code snippets.
- Retrieve information. Extract data by making the most of the cheerio library. For that, you need to open the DevTools in your browser with Ctrl+Shift+I and access the Elements section. Web scraping with Node.js suggests using the request-module to get HTML of a page. Add a scraper.js file to your project and run a code snippet with the Set () structure to avoid duplicates.
Now that you’ve got a better understanding of how to grab any site information, you’re granted access to huge resources and can make avail of them to your best advantage. Don’t disregard the AngularJS framework that can assist you in keeping what you’ve crawled in its database and downloading it.
Node.js web scraping can be a piece of cake for everyone. Do it right to harvest any content hassle-free!
