Your env variables are dependencies. Treat them as such.
npm install require-env --save
--save automatically updates your package.json file - tell your friends)
var env = require('require-env'), foo = env.require('FOO');
If there's a FOO variable in your app's environment, ie
foo is set. If not, then an exception is thrown and your app will crash.
This mirrors the behavior of the node.js
require method which will crash if the given module is not found. This is especially useful on services such as Heroku which store database connection info in environment variables. If you don't have the URL for a database you require, better to crash now than to crash somewhere inside someone else's connect method.
This module also contains some convenience functions for dealing with environment variables in node:
returns true if
process.env[name] exists and is not
Synchronously loads environment variables of the form
KEY=VALUE from the given file and adds them to
process.env. Useful for running tests with different environment variables. Understands comments (lines beginning with
#). Does not crash if the file is missing (just prints a warning). Written with Foreman's
.env files in mind.
returns the environment variable with the given
name if it exists and is not
undefined. Throws an Error if otherwise.
url.parse on the variable with the given
pass variables from any resulting
auth info and parses any resulting
port into an
int. Written with RedisToGo URLs in mind.
