How to get data by key wss.clients without enumeration of all users?

Question

JavaScript

Hello. We are talking about the server (WebSocket).
In wss.clients all users, in order to get information about a specific user, you have to iterate and compare all of them:

const WebSocket = require('ws');
const wss = new WebSocket.server({ port:8080 });
...
wss.clients.forEach(function each(client) {
  if(id === client.id) {
        console.log('ID: ' + client.id)
        console.log('KEY:' + client. key)
   }
})

Is it possible to somehow get data by a specific id or key without enumeration of all connected users?
PS wss.clients is not an array.

Answer 1

You can create your own object for storing users and save the Id there when connecting, then you can refer to specific users

myClients = [];
wss.on('connection', function(ws) {
    myClients.push(ws);
});

You can also dig in the socket.io git , this is a wrapper over standard sockets, I think you can find a more correct and scalable solution there
