Boilerplate for Node.js server, devmode

server.js

//Incs
var express     = require('express');
var path        = require('path');     
var cors        = require('cors');
var bodyParser  = require('body-parser');
var nconf       = require('nconf');

//Set base root for modules
process.env.root = __dirname;

//Load config. This will depend on what your NODE_ENV var is set to
nconf.argv().env().file({ file:'config/config-' + process.env.NODE_ENV + '.json'});

//Create app stub
var app = express();
var http = require('http').createServer(app);

//Setup socket with chosen port
var io = require('socket.io')();
io.listen(http);

//Begin server
http.listen(8201, function(){
    'use strict';
});

//Enable parsing json bodies
app.use(bodyParser.json());
app.use(cors());

//Set template engine
app.set('view engine', 'ejs');

//Enable all sources. FOR DEV ONLY.
app.all('*', function(req, res, next) {
   res.header("Access-Control-Allow-Origin", "*");
   res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,OPTIONS');
   res.header("Access-Control-Allow-Headers", "X-Requested-With");
   res.header('Access-Control-Allow-Headers', 'Content-Type');
   next();
});

//Test connection
io.on('connect', function (socket) {
    var payload = {test: "test"};
    io.sockets.emit('connected-user', payload);
