load-env-settings

load-env-settings is a zero-dependency module that loads environment variables from a .env file into a global variable.

Install

npm install load-env-settings

Usage

Create a .env file in the root of your project:

ADMIN_USER=YOUR_ADMIN_USER
SECRET_KEY=ULTRASECRETKEY

As early as possible in your application, import and configure the package:

require( 'load-env-settings' ).load()

load( [ settings[, nameGlobal[, allowAny ] ] ] )

• settings: (Object) Object with info about expected settings. If a setting included in this argument does not appear in .env file (or the file does not exist), it will be saved in the global variable with their default value. The key of each setting will be their name in the global variable. Each expected setting can contain a env (name of setting in .env file), a type (type of value of setting), a defaultValue (default value of setting) and a allowEmpty (if it is not allowed, empty settings use their default value) properties. More information in Settings. Defaults: {}
• nameGlobal: (String) The name of the global variable that save the settings. Default AppSettings
