Seems you missed something to start up your application. I write a sample demo for you,the project secture is simple just like below:

Code of wstest.js:

const WebSocket = require('ws');
const port = process.env.PORT || 8080

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

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

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

I use vs code to deploy this project directly, so that this project will under folder : /home/site/wwwroot/ so we should use node command to start up it, just as below:

After deploying it, let's test it from local:
