index.js for node configs

index.js

var fs = require('fs');
var path = require('path');

var env = process.env.NODE_ENV || 'development';
var config = JSON.parse(fs.readFileSync(__dirname + '/'+env+'.json'));

config.env = env;
config.root = path.dirname(require.main.filename);

module.exports = config;

You just create a directory /config, add there this file and then you can add there configurations for different environment, such as development.json. Usage is pretty simple:

    var config = require('config');
