HTML parsing/serialization toolset for Node.js. WHATWG HTML Living Standard (aka HTML5)-compliant.

parse5 provides nearly everything you may need when dealing with HTML. It's the fastest spec-compliant HTML parser for Node to date. It parses HTML the way the latest version of your browser does. It has proven itself reliable in such projects as jsdom, Angular, Lit, Cheerio, rehype and many more.
