Structure a node project your way with the ability to require models, controllers, or any file dynamically.

// Load crave from the repository.
var crave = require('../../libs/index.js');
// or
// Load crave from an installed npm module
// var crave = require('crave');


var express = require('express'),
    mongoose = require('mongoose'),
    path = require('path');

var config = {
  //
  // Server configs can be placed here.
  // 
};

// Create an express application object.
var app = express();

// Method to connect to a MongoDB database.
var connect = function(callback) {
  mongoose.connect('mongodb://localhost/crave-example-simple');
  mongoose.connection.on('error', console.error.bind(console, 'connection error:'));
  mongoose.connection.once('open', function() {
    callback(undefined, mongoose);
  });
};

// Method to connect to database and start the server.
var start = function(err, files, returnValues) {
  if(err) return console.log(err);

  //console.log(files);
  //console.log(returnValues);

  connect(function(err) {
    if(err) return console.log(err);

// You can pass any number of parameters by continuing to overload the function below.  Finally the start server method
// will be called.
