### For Node.js / NPM users
|
|
While not physically hosted by NPM, it's still possible to install using NPM tools like so ([npm docs](https://docs.npmjs.com/cli/install)):
|
|
|
|
```
|
|
npm install uNetworking/uWebSockets.js#v15.0.0
|
|
```
|
|
|
|
This project is a Google V8 (Node.js or not) web server built to be efficient and stable. It makes use of µWebSockets, the C++ project, and exposes its features to JavaScript developers. This includes mainly Http & WebSockets, SSL and non-SSL. Prominent users include bitfinex.com, they run ther trading APIs on this server.
|
|
|
|
##### In a nutshell
|
|
```javascript
|
|
const uWS = require('uWebSockets.js');
|
|
const port = 3000;
|
|
|
|
uWS.SSLApp({
|
|
/* cert, key and such specified here, or use uWS.App */
|
|
}).get('/whatsmyuseragent', (res, req) => {
|
|
res.writeHeader(
|
|
'content-type', 'text/html; charset= utf-8'
|
|
).end(
|
|
'Your user agent is: ' + req.getHeader('user-agent')
|
|
);
|
|
}).get('/*', (res, req) => {
|
|
res.end('Wildcard route');
|
|
}).listen(port, (token) => {
|
|
if (token) {
|
|
console.log('Listening to port ' + port);
|
|
} else {
|
|
console.log('Failed to listen to port ' + port);
|
|
}
|
|
});
|
|
```
|
|
|
|
### Streams
|
|
Proper streaming of huge data is supported over Http/Https and demonstrated with examples. Here's a shot of me watching real-time streamed HD video from Node.js while simultaneously scoring a 115k req/sec with wrk. For my computer, that's about 5x that of vanilla Node.js (without any HD video streaming/playing).
|

|
|
|
|
|
|
### Benchmarks
|
|
Performance retention is about 65% that of the native C++ [µWebSockets](https://github.com/uNetworking/uWebSockets) v0.15. That makes it some 20x as fast as Deno and even faster than most C++-only servers, all from within a JavaScript VM.
