Running Express.js in Production Mode

gistfile1.js

// First export vars 
echo export NODE_ENV=production >> ~/.bash_profile
$ source ~/.bash_profile

// then start the serverin some mode (production default)
NODE_ENV=testing node app.js



Load the environment config in ./config/index.js

var env = process.env.NODE_ENV || 'development'
  , cfg = require('./config.'+env);

module.exports = cfg;
Define some defaults in ./config/config.global.js

var config = module.exports = {};

config.env = 'development';
config.hostname = 'dev.example.com';

//mongo database
config.mongo = {};
config.mongo.uri = process.env.MONGO_URI || 'localhost';
config.mongo.db = 'example_dev';

Override the defaults in ./config/config.test.js

var config = require('./config.global');

config.env = 'test';
config.hostname = 'test.example';
config.mongo.db = 'example_test';

module.exports = config;

Using it in ./models/user.js:
var mongoose = require('mongoose')
, cfg = require('../config')
, db = mongoose.createConnection(cfg.mongo.uri, cfg.mongo.db);
Running your app in test environment:

NODE_ENV=test node ./app.js
