Socket.io custom client ID

Question

I\'m making a chat app with socket.io, and I\'d like to use my custom client id, instead of the default ones (8411473621394412707, 1120516437992682114

You can create an array on the server, and store custom objects on it. For example, you could store the id created by Socket.io and a custom ID sent by each client to the server:

var util = require("util"),
    io = require('/socket.io').listen(8080),
    fs = require('fs'),
    os = require('os'),
    url = require('url');

    var clients =[];

    io.sockets.on('connection', function (socket) {

        socket.on('storeClientInfo', function (data) {

            var clientInfo = new Object();
            clientInfo.customId         = data.customId;
            clientInfo.clientId     = socket.id;
            clients.push(clientInfo);
        });

        socket.on('disconnect', function (data) {

            for( var i=0, len=clients.length; i

in this example, you need to call storeClientInfo from each client.

Hope this helps.
