configo

Hierarchical configuration with files and environment variables for node and the browser.

Install

npm i --save configo

Usage

1. Create a config folder at the root of your project. Within it, create a default folder.

mkdir config
mkdir config/default

2. Within the default folder, create a private.js file that exports an Object containing your private configuration variables. Once that's done, create a public.js file that does the same but for your publicly accessible configuration variables.

// ./config/default/private.js
module.exports = {
  WHO_IS_BATMAN: 'Bruce Wayne'
};

// ./config/default/public.js
module.exports = {
  NODE_ENV: process.env.NODE_ENV
};

3. Require configo on the server and in browsers (using browserify) and easily access your configuration variables.

// On the server
var conf = require('configo');

console.log(conf.get('WHO_IS_BATMAN')); // Bruce Wayne
console.log(conf.get('NODE_ENV'));      // production

// In browsers
var conf = require('configo');

console.log(conf.get('WHO_IS_BATMAN')); // undefined
console.log(conf.get('NODE_ENV'));      // production

NOTE: Your private configuration variables are not included in the outputted browserify file.
