Flexible lightweight configuration loader

Installation

$ npm install config-node

Basic usage

var config = require('config-node')();
console.log(config.server.port);

config will contain the contents of the configuration file named process.env.NODE_ENV or 'development', on the folder config/.<br /> It can be a JSON, a JS that fills module.exports or a directory with an index.js inside.

You probably noticed there's a function call in there. It needs to be added once to load the data. This is where you can put your options. You'll probably do that on your main js file, in all the other ones you only require it:

// in db.js
var config = require('config-node');
console.log(config.db.port);

Options

These are the defaults:

var config = require('config-node')({
	dir: 'config', // where to look for files 
	ext: null, // spoil the fun, tell me which one it is ('' for directory). Improves performance.
	env: process.env.NODE_ENV || 'development' // set which one instead of smart defaults
});

In order to support more formats beyond json, js and directories. You add a file with a different extension to the config folder and pass an option named as the extension with a function that takes the file string data and returns an object, synchronously!

var config = require('config-node')({
	png: function(data) { return convertPNGtoObjectSomehow(data); }
});

Check the examples to see more use cases.

flatiron/nconf - If you need all that, this one is the best. It has it all
lorenwest/node-config - Good, too complex for me. I'd never need things like file watching(use nodemon)
dominictarr/config-chain - Very cool one, too complex for most simple cases
dominictarr/rc - It's great, more oriented to loading files from outside the project
pgte/konphyg - Also great, but only JSON and does failed filesystem reads in most cases
scottmotte/dotenv - Loads environment variables from .env file directly into process.env
Feel free to suggest others, these are the ones I found and used for inspiration

Why use this project over others

It's simple, the code is short and clean
It's extensible, it can support coffee, yaml, ini or anything else you want, just DIY.
It has no dependencies. If you need yaml, just include the one you prefer and pass it over.
It's fast. Loading configuration needs to be fast, with the ext option this module is mostly a smart require.

Some concepts taken into account

Convention over configuration, tuned for the mayority.
Pareto principle. I aim for that 80% that needs only the 20% of the features.
KISS principle. It's really simple but it does the job.
YAGNI. I prefer to add features based on requests.
