Socket IO Server to Server

Question

Is it possible for a server to connect to another using Socket.IO and be treated like a client?

And have it join rooms, recieve io.sockets.in('lobby').emit(). And more?

The first server is also listening for connections/messages as well.

Hey Brad, here's my full .js app below for reference:

var io = require("socket.io").listen(8099); io.set('log level', 1);  io.sockets.on("connection", function (socket) {      console.log('A Client has Connected to this Server');      //Let Everyone Know I just Joined        socket.broadcast.to('lobby').emit("message",'UC,' + socket.id); // Send to everyone in Room but NOT me     socket.on("message", function (data) {  //Missing code socket2.send('message,' + data); //Forward Message to Second Server  });  socket.on("disconnect", function (data) {     //Send Notification to Second Server     //Need to figure out later      //Send Notification to Everyone     socket.broadcast.emit("message",'UD,' + socket.id ); //Send to Everyone but NOT me      //Remove user from Session ID     arSessionIDs.removeByValue(socket.id);            //Send Notification to Console     console.log("disconnecting " + arRoster[socket.id][1]); });  });  var io_client = require( 'socket.io-client' ); var socket2 = io_client.connect('http://192.168.0.104:8090'); socket2.on('connect', function () { socket2.emit('C3434M,Test'); });

Yes, absolutely. Just use the Socket.IO client in your server application directly.

You can install it with npm install socket.io-client. Then to use:

var socket = io.connect('http://example.com'); socket.on('connect', function () {   // socket connected   socket.emit('server custom event', { my: 'data' }); });
