HTTP2 and WS Websocket fails

[najibghadri]

• Version: v10.16.0
• Platform: 64-bit Windows 10
• With self signed cert.
• Client tester: used many, other node ws client code, socket testers, etc, not working.

I know about this issue 15230, and there is a supposed POC which is very hacky. I tried to set up an http2 server with ws websocket, like this:

const server = http2.createSecureServer({
  enableConnectProtocol: true,
  key: fs.readFileSync('localhost-privkey.pem'),
  cert: fs.readFileSync('localhost-cert.pem')
});

const wss = new WebSocket.Server({ server });

wss.on('connection', function connection(ws) {
  console.log('connected user');

  ws.on('message', function incoming(message) {
    console.log('received: %s', message);
  });

  ws.send('something');
});

server.listen(3000);

When I connect with a client to wss://localhost:3000 it fails.

error:

events.js:174
      throw er; // Unhandled 'error' event
      ^

Error: read ECONNRESET

Thank you!

If there is no solution or you say there isn't going to be a solution anytime soon could you suggest a way so that I can use http2 and websockets on one node server? Thank you!

See websockets/ws#1458

Thanks @lpinca !

Based on someone's comment on the thread linked above, "using node's http2 framework with the allowHTTP1: true option then setting a ws server to listen on the http2 server just works."
Worked for me too, websocket connections builds up, http api is on http2 so, looks ok, idk how it works and if this is a correct long-term solution but I will keep using it for now. If I will have problems I will separate the server into HTTP2 and HTTPS WSS servers
