Sending message to specific client with socket.io and empty message queue

Question

I´m going crazy with socket.io! Documentation is so bad it\'s simply not true.

I want to send a feedback to specific client over socket.io

My server side loo

Answer 1

to send a message to a specific client save every one that connects to the server in an Object.

var socketio = require('socket.io');
var clients = {};
var io = socketio.listen(app);

io.sockets.on('connection', function (socket) {
  clients[socket.id] = socket;
});

then you can later do something like this:

var socket = clients[sId];
socket.emit('show', {});
