llhttp - new HTTP 1.1 parser for Node.js | JS Conf 2019

Node.js has been using a derivative of nginx’s parser with a lot of
customization/rewrite since its inception. Despite being fast
enough, the project architecture made it very hard to maintain in a
long run. To mitigate that, the author has created a tool to
generate the new HTTP parser called “llhttp” from the TypeScript
code in understandable, verifiable, and maintainable way.
Incidentally, the performance of “llhttp” is two times better than
of the old parser. In this talk we’ll walk through the basics of
generating such parsers and how “llhttp” works.
