I\'m having some problems with socket.io, and I have no idea how to solve it. I\'ve an app with a login system with socket.io to manage user interactions. Also I\'ve an arra
I know it has been a long time since you asked this, but Just 4 ago I published a module for node js, express and socket.io which manages that exactly thing you wanted. Check the Usage and Example, I hope you will find this module helpful!
You can install it via NPM socket.io.users This is a node js module for socket.io applications. One user per client.
Some of the usage code
var express = require('express');
var app = express();
var server = require('http').createServer(app);
var socketUsers = require('socket.io.users');
//....
socketUsers.Session(app);//IMPORTANT
//...
var rootIo = require('socket.io')(server); //default '/' as namespace.
var chatIo = rootIo.of('/chat');
var rootUsers = socketUsers.Users; /* default '/' as namespace.
Each namespace has IT's OWN users object list,
but the Id of a user of any other namespace may
has the same value if request comes from the same client-machine-user.
This makes easy to keep a kind of
synchronization between all users of all different namespaces. */
var chatUsers = socketUsers.Users.of('/chat'); //
rootIo.use(socketUsers.Middleware());/*IMPORTANT but no errors if you want
to skip it for a io.of(namespace)
that you don't want the socket.io.users' support. */
chatUsers.use(socketUsers.Middleware());
chatUsers.on('connected',function(user){
console.log(user.id + ' has connected to the CHAT');
user.store.username = 'username setted by server side'; /*at the store
property you can store any type of properties
and objects you want to share between your user's sockets. */
user.socket.on('any event', function(data){
/*user.socket is the current socket, to get all connected sockets from this
user, use: user.sockets */
});
chatIo.emit('set username',user.store.username);
});
rootUsers.on('connected',function(user){
console.log('User has connected with ID: '+ user.id);
});
rootUsers.on('connection',function(user){
console.log('Socket ID: '+user.socket.id+' is user with ID: '+user.id);
});
rootUsers.on('disconnected',function(user){
console.log('User with ID: '+user.id+'is gone away :(');
});
//...server.listen blabla..
