htmlparser2

htmlparser2 is a fast and forgiving HTML/XML parser for Node.js that processes markup in a streaming, event-driven manner. It can handle malformed HTML gracefully and is designed for high performance in server-side environments. The library provides a SAX-like interface, emitting events as it parses tokens like tags, text, and comments.

Also known as: html parser 2, html-parser-2, htmlparser 2, htmlparser2 library, node-htmlparser2

Why learn htmlparser2?

Developers should use htmlparser2 when building web scrapers, crawlers, or tools that need to extract data from HTML/XML documents efficiently in Node.js applications. It's ideal for real-time parsing of large or streaming HTML content, such as in server-side rendering, content analysis, or data mining projects, due to its low memory footprint and speed.
