EnvBang for Node.js

Ensure you have all the right environment variables set in your app.

Installation & Usage

As early as possible in your application require envbang and pass it your required environment variables.

EnvBang = require('envbang-node');
envbang = new EnvBang(['NODE_ENV', 'PORT', 'MONGOHQ_URL']);
// Once initialized, run #check() to ensure your environment variables are present
envbang.check();

If you are missing any environment variables, envbang will throw an error and give you a list of the variables you're missing:

The following required environment variables are missing:
=> NODE_ENV
=> PORT
=> MONGOHQ_URL

Inspiration

This package is meant to be used as a companion to dotenv-node. We are big fans of configuration via environment variables, but it can occasionally get a little crazy when you have a team of developers trying to keep up with changes to a .env file. The goal is to give clear feedback on application configuration to help reduce developer confusion and frustration.
