Get total number of connected clients on each new connection

[nodesocket]

I am trying to print the number of connected clients each time a connection is established.

Here is the server code:

const WebSocket = require('ws');

const wss = new WebSocket.Server();

wss.on('connection', (ws) => {
    ws.on('message', (m) => {
        console.log('received: %s', m);
    });

    console.log(wss.clients.length);
});

When I connect with a client though I am seeing wss.clients.length as undefined.

wss.clients is a set not an array. Use wss.clients.size.
