On most projects you end up wiring up a bunch of custom logic to handle your config, which is often injected as environment variables - think loading from a secure source, validation logic, type safety, pre-commit git scanning, etc.

It's annoying to do it right, so people often take shortcuts - skip adding validation, send files over slack, don't add docs, etc...

The common pattern of using a .env.example file leads to constant syncing problems, and we often have many sources of truth about our config (.env.example, hand-written types, validation code, comments scattered throughout the codebase)

This tool lets you express additional schema info about the config your application needs via decorators in a .env file, and optionally set values, either directly if they are not sensitive, or via calls to an external service. This shouldn't be something we need to recreate when scaffolding out every new project. There should be a single source of truth - and it should work with any framework/language.
