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 looks like this:

app.get('/upload', requiresLogin, function(request, response) {     response.render('upload/index.jade');     io.sockets.on('connection', function (socket) {         console.log('SOCKET ID ' + socket.id);         io.sockets.socket(socket.id).emit('new', 'hello');     }); }); 

and the client side looks like this:

$(document).ready(function() {     var socket = io.connect('http://localhost:80/socket.io/socket.io.js');     socket.on('new', function (data) {          console.log(socket.id);         console.log(data);          //$('#state').html(data.status);     }); }); 

but the client does simply nothing. I have tried nearly everything. Can someone tell me what I am doing wrong, please! :(

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', {});
