µWebSockets.js is an HTTP/WebSocket server for Node.js that runs 8.5x that of Fastify and at least 10x that of Socket.IO. It comes with both router and pub/sub support and is suited for extraordinary performance needs. Browse the documentation and see the main repo. There are tons of examples but here's the gist of it all:
``javascript
/ Non-SSL is simply App() /
require('uWebSockets.js').SSLApp({
/ There are more SSL options, cut for brevity /
key_file_name: 'misc/key.pem',
cert_file_name: 'misc/cert.pem',
}).ws('/*', {
/ There are many common helper features /
idleTimeout: 30,
maxBackpressure: 1024,
maxPayloadLength: 512,
compression: DEDICATED_COMPRESSOR_3KB,
/ For brevity we skip the other events (upgrade, open, ping, pong, close) /
message: (ws, message, isBinary) => {
/ You can do app.publish('sensors/home/temperature', '22C') kind of pub/sub as well /
/ Here we echo the message back, using compression if available /
let ok = ws.send(message, isBinary, true);
}
}).get('/*', (res, req) => {
/ It does Http as well /
res.writeStatus('200 OK').writeHeader('IsExample', 'Yes').end('Hello there!');
}).listen(9001, (listenSocket) => {
if (listenSocket) {
console.log('Listening to port 9001');
}
});

We recommend, for simplicity installing with yarn add uWebSockets.js@uNetworking/uWebSockets.js#v19.3.0` or any such release.
Being an open source project, you are of course perfectly free to choose other ways of installation as you might prefer.

µWebSockets.js is the Node.js integration of µWebSockets; the standalone C++ project. If performance is of utter importance, you don't necessarily have to use JavaScript/Node.js but could write apps in C++ using µWebSockets directly. It works exactly the same way, and will offer unbeatable performance for those highly demanding applications. Either way - the two projects both follow the same security testing, compliance testing and receive the same bug fixes and features. They are part of the same family.
