Node.js Environment Variable Management

Atmosphere

Node.js Environment Variable Management

Why should I use this?

• prevents writing "process.env" everywhere in your project's code.
• increases testability because you can mock different environments (due to above)

How to Use

1) Install via NPM

$ npm install atmosphere

2) Initialize

// process.env can be substituted for any object
var atmo = require('atmosphere')(process.env);

3) Get Variables

// Access Environment Variables
atmo.get('port'); // 3000

Overrides

Need to override some environment variables?
It's not recommended, but you can.

// Override
var atmo = require('atmosphere')(process.env, { port : 8080 });
atmo.get('port'); // 8080

Upcoming

• Environment Variable Prefix (MYAPP_PORT -> PORT)
• Auto-capitalization (port -> PORT)
• Replacing spaces with underscores
• Converting the return value to another type ('3000' -> 3000)
