@paulavery/config v1.0.1

An environment config loader

This module allows you to easily load your apps configuration from environment variables. You specify a default config object, and the module parses environment variables based on that objects structure and data types.

Setup:

import config from '@paulavery/config';

let settings = config('appName', {
	serverUrl: 'http://github.com/',
	mysql: {
		db: 'app-name',
		host: 'localhost',
		port: 3306,
		user: 'root'
	}
});

Variables:

APPNAME_SERVERURL='http://dev.github.com/'
APPNAME_MYSQL_DB=app-name-dev
APPNAME_MYSQL_PORT=2207

Result:

{
	serverUrl: 'http://dev.github.com/',
	mysql: {
		db: 'app-name-dev',
		host: 'localhost',
		port: 2207,
		user: 'root'
	}
}

Supported datatypes are string, number, boolean and obviously object.

To make specifying local configs easy, it also uses the dotenv package to load a '.env' file with environment variables.
