:zap: Simple performance

µWebSockets.js is a standards compliant web server written in 10,000 lines of C++. It is exposed to Node.js as a simple-to-use, native V8 addon and performs at least 10x that of Socket.IO, 8.5x that of Fastify. It makes up the core components of Bun and is the fastest standards compliant web server in the TechEmpower (not endorsed) benchmarks.

We aren't in the NPM registry but you can easily install it with the NPM client:

  • npm install uNetworking/uWebSockets.js#v20.57.0
  • Browse the documentation and see the main repo. There are tons of examples but here's the gist of it all:
