Semalt Overview Of Web Scraping In Node.js

A web scraper is a tool used to extract data from the internet. It may access the World Wide Web using the Hypertext Transfer Protocol, or through the web browsers. Web scraping can be done manually, but the term typically refers to an automated process implemented using bots or web crawlers. The current web scrapers range from the ad-hoc, requiring human efforts, to fully automated systems that can convert the entire website into structured information.
