load-env
Helper library to manage environment variables.
Installation
npm install --save @ambassify/load-env
Usage
Will throw an error when the environment variable is not set and no default is specified.
const load_env = require('@ambassify/load-env');
const NODE_ENV = load_env('NODE_ENV', 'production');
load_env()
load_env(variableName, [defaultValue])
- variableName: The environment variable to load.
- defaultValue: The default value when an environment variable is not set.
withPrefix()
Create a load_env function that looks for prefixed environment variables and falls back to unprefixed version. If you do not provide a prefix, it will try to generate one using the closest package.json's name field.
const withPrefix = require('@ambassify/load-env/with-prefix');
const load_env = withPrefix();
// assuming package.json with: { "name": "@acme/foo-bar" }
// and: process.env.FOO_BAR_NODE_ENV = production
// and: process.env.NODE_ENV = staging
load_env('NODE_ENV');
// <-- "production"
