Simple, secure[1] & standards compliant[2] web server for the most demanding[3] of applications. Read more...
### :bulb: In a nutshell
Think of it as a complete replacement to both Express.js and Socket.IO, written entirely in C/C++ for maximum performance and reliability. Browse the [documentation](https://unetworking.github.io/uWebSockets.js/generated/). There are tons of [examples](examples) but here's the gist of it all:
```javascript
/* Non-SSL is simply App() */
require('uWebSockets.js').SSLApp({
/* There are tons of SSL options */
key_file_name: 'misc/key.pem',
cert_file_name: 'misc/cert.pem',
}).ws('/*', {
/* For brevity we skip the other events */
message: (ws, message, isBinary) => {
let ok = ws.send(message, isBinary);
}
}).any('/*', (res, req) => {
/* Let's deny all Http */
res.end('Nothing to see here!');
}).listen(9001, (listenSocket) => {
if (listenSocket) {
console.log('Listening to port 9001');
}
});
```
### :rocket: Ready all thrusters
Install with `npm install uNetworking/uWebSockets.js#v18.1.0` or any such [release](https://github.com/uNetworking/uWebSockets.js/releases). No compiler needed.
Real-world tests over TLS 1.3 and Ethernet puts us **5x** as efficient as Socket.IO, **2x** as efficient as websockets/ws.
