dotenv

Load environment variables at runtime from a .env file.

about

Deploying applications should be simple. This implies constraints:

The twelve-factor app stores config in environment variables
(often shortened to env vars or env). Env vars are easy to change
between deploys without changing any code… they are a language- and
OS-agnostic standard.

An environment is the set of variables known to a process (say, PATH, PORT, …).
It is desirable to mimic the production environment during development (testing,
staging, …) by reading these values from a file.

This library parses that file and optionally merges its values with the built-in
Platform.environment map.

usage

See documentation and examples.
