env-variable

A cross platform env-variable for browsers and node. Of course, browsers doesn't have environment variables but we do have hashtags and localStorage which we will use as fallback.

hashtags

This is a really easy way of adding some trigger some environment variables that you might use for debugging. We assume that the hashtag (#) contains a query string who's key is the name and the value.. the value.

localStorage

If you want more persisting env variables you can set a query string of env variables in localStorage. It will attempt to use the env variable.

Installation

This module is written for node and browserify and can be installed using npm:

npm install --save env-variable

Usage

This module exposes a node / module.exports interface.

var env = require('env-variable')();

As you can see from the example above we execute the required module. You can alternately store it but I don't assume this a common pattern. When you execute the function it returns an object with all the env variables.

When you execute the function you can alternately pass it an object which will be seen as the default env variables and all fallbacks and process.env will be merged in to this object.

var env = require('env-variable')({
  foo: 'bar',
  NODE_ENV: 'production'
});

Oh, in env-variable we don't really care how you write your env variables. We automatically add an extra lower case version of the variables so you can access everything in one consistent way.

And that's basically everything you need to know. random high fives.
