#### In a nutshell.
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');
}
});
```
