[![Build Status](https://secure.travis-ci.org/ctavan/node-getenv.png)](http://travis-ci.org/ctavan/node-getenv)

Helper to get and typecast environment variables. This is especially useful if you are building [Twelve-Factor-Apps](http://www.12factor.net/) where all configuration is stored in the environment.

var host = getenv('HTTP_HOST'); // same as getenv.string('HTTP_HOST');

var abTestRatio = getenv.float('AB_TEST_RATIO');

var primes = getenv.array('PRIMES', 'int');

All methods accept a fallback value that will be returned if the requested environment variable is not set. If the fallback value is omitted and if the requested environment variable does not exist, an exception is thrown.

Alias for `env.string(name, [fallback])`.

Split value of the environment variable at each comma and return the resulting array where each value has been typecast according to the `type` parameter. An array can be provided as `fallback`.

Return a list of environment variables based on a `spec`:

  foo: "FOO", // throws if FOO doesn't exist

  bar: ["BAR", "defaultval"], // set a default value

  baz: ["BAZ", "defaultval", "string"], // parse into type

  quux: ["QUUX", undefined, "integer"] // parse & throw

Disallows fallbacks in environments where you don't want to rely on brittle development defaults (e.g production, integration testing). For example, to disable fallbacks if we indicate production via `NODE_ENV`:

if (process.env.NODE_ENV === 'production') {
