Helper for environment variables in node.
npm install @ambassify/load-envHelper library to manage environment variables.
``shell`
npm install --save @ambassify/load-env
Will throw an error when the environment variable is not set and no default is specified.
`javascript`
const load_env = require('@ambassify/load-env');
const NODE_ENV = load_env('NODE_ENV', 'production');
#### load_env()
`javascript`
load_env(variableName, [defaultValue])
- variableName: The environment variable to load.
- defaultValue: The default value when an environment variable is not set.
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.
`javascript
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"
