envi

Installation

npm install -g envi

Usage

☁  bin [master] ⚡ envi 
Created your conf directory with env.js and env.json!
Install latest version of nconf? y or n [y]

Explanation

You need configuration vars that are enviromentally specific. You also want them to use nconf goodness (https://github.com/flatiron/nconf). You want the environment to default to being development if process.env.NODE_ENV is undefined.

Running envi will give you a conf directory that looks like this:

conf/env.js
conf/env.json

So you can do this in your code:

env = require('./conf/env');
console.log(env.hello); //outputs I'm dev by default, otherwise reads process.env.NODE_ENV

Where env.json looks like:

{
  "development":{
    "hello": "I'm dev"
  }
  , "test": {
    "hello": "I'm test"
  }
  , "staging": {
    "hello": "I'm staging"
  }
  , "production": {
    "hello": "I'm production"
  }
}

Or, leverage nconf coolness:

node myprogram.js --hello "I've been overridden"
