MultiClient Socket.io/Node.js

Question

So what I want to do is to make Index (for example) to send messages to Index2, The reason I want to do this is so that I can have two different messaging clients. Is there any way to do this? for example lets say Index is the controller and Index2 is the game.

Here is my code for index and Index2:

<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script src="/socket.io/socket.io.js"></script>
<script type="text/javascript">
    jQuery(function($) {
        var socket = io.connect();
        var $messageForm = $('#send-message');
        var $messageBox = $('#message');
        var $chat = $('#chat');

        $messageForm.submit(function(e) {
            e.preventDefault();
            socket.emit('send message', $messageBox.val());
            $messageBox.val('');
        });

        socket.on('new message', function(data) {
            $chat.append(data + "<br/>");
        });
    });
</script>

Server side:

var express = require('express'),
app = express(),
server = require('http').createServer(app),
io = require('socket.io').listen(server);

server.listen(3000);

app.get('/:index', function(req, res) {
    res.sendfile(__dirname + '/Index.html', '/index2.html');
});

io.sockets.on('connection', function(socket) {
    socket.on('send message', function(data) {
        io.sockets.emit('new message', data);
    });
});

Thanks, I'll give that a try, but can you give me an example? — MatOak

As long as you connect the socket to the same place on each client, they will send messages to each other (docs).

var socket = io("https://my.domain.com/shared")

Use rooms / namespaces on the server (docs).

serverio.of('/shared')

So the var socket = io("my.domain.com/shared") replaces the var socket = io.connect(); on the Index2? Or does it replace on both index and index2? Also where does the "serverio.of('/shared')" go in the app.js file? Thanks

io() is a shortcut for io.connect(). The server io goes in your server javascript (maybe called app.js?)

Hi, Aj Can you show me where to put the two lines of code? Im not exactly sure where in the document to put them, Thanks

AJcodez Over a year ago

Put your code (w/e you have) online somewhere and give a link. More than happy to help.
