Calling a function from server-side on the client-side (Node.js)

Question

I have the following code on the server:

var game = io.listen(app);

game.sockets.on('connection', function(socket){
    storePlayers(socket.id);
    //Only the player the connects gets this message
    socket.emit('firstTime', {message: 'Welcome!'});

    //If a player disconnects, a message will be sent to all the sockets.
    socket.on('disconnect', function(){
        game.sockets.emit('exit', {message: 'Player ' + socket.id + ' left the game...!'});
    });

    //When a player connects, all the players will get this message.
    game.sockets.emit('entrance', {message: 'Player ' + socket.id + ' is online'});
});

I want to get a hold of the storePlayers(id) function. The reason for this being when a socket connects, an object is supposed to be created with the specific socket.id on the client-side.

How would I go about doing such a thing?

Answer 1

From what I understand, you want the client to send an id when it connects to your server.You can achieve this by sending a message once the client connects to your server.

Client side

var socket = io.connect('your_server')    
socket.on('connect', function () {
        clientId = generate_id(); //however you want to generate the id
        socket.emit('newUser', {id: clientId});
    }

You can then capture the message 'newUser' on the server and retrieve the id of the connected client.
