filter-env

filter-env iterates over process.env and returns an object containing environment variables whose name matches a regular expression. Optionally, it can parse environment variable values as JSON.

Usage

const config = filterEnv(/^TEST-/, { json: true, freeze: true });

Arguments

• validate: A validation function or regular expression to test the environment variable key
• options: Optional configuration
  • json: true to parse environment variable value as JSON. Throws an error if a value is not valid JSON. Defaults to false
  • immutable: true to freeze the returned object (and child objects). Defaults to false
  • format: A function that formats the environment variable name in the returned object. If the format function returns a key that already exists, the variable will not be included in the returned object. By default, the key is not changed.
