I client connects to a sever specifying a room they wish to join, that client is then binded to that one and only room.
The server broadcasts a event to the room, forwarding the message on to any other connected clients.
In the below example connected_client.js
is listening to any messages, and will log the output.
[message]: {"room": "anything", "greeting": "Hello world"}

// Authentication | |
var passport = require('passport'); | |
var LocalStrategy = require('passport-local').Strategy; | |
var sessions = require("client-sessions"); | |
var server = restify.createServer(); | |
server.use(restify.queryParser()); | |
server.use(restify.bodyParser()); |
For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.
Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon
with HyperThreading enabled, but it can work without problem on slower machines.
You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
