Example of authenticating websockets with JWTs.

gistfile1.js

var WebSocketServer = require('ws').Server;
var wss = new WebSocketServer({port: 8080});

var jwt = require('jsonwebtoken');

/**
The way I like to work with 'ws' is to convert everything to an event if possible.
**/
function toEvent (message) {
  try {
    var event = JSON.parse(message);
    this.emit(event.type, event.payload);
  } catch(err) {
    console.log('not an event' , err);
  }
}

wss.on('connection', function(ws) {
  ws.on('message', toEvent)
    .on('authenticate', function (data) {
      jwt.verify(data.token, options, function (err, decoded) {
       //now is authenticated
      });
    });
  
  ws.send('something');
});

@OBorce u get my point, that's why what I do is only save the userId as key to users object then save the token as it's value. so that every time the user's token changes u'll know which token to update due to the saved userId.

Is there any option to connect to a WebSocket through username and password authentication?
