I wonder if we just make otp_app required to deal with config loading. That way apps can't invent their own config loading. Might clean up code.

I prefer to use the module scoping rather than relying on global scope such as config :name, ...

Code looks good but we will need to set the otp_app for tests

@btkostner ready!

[btkostner]

Code looks good though this technically is a breaking change and I know there are a couple of services already using it.

[btkostner]

We can make this a non breaking change by making the option not required and defaulting to [] configuration.

@btkostner that sounds like the way to go 🚀

Ran into some issues with config loading and required fields. This will require more work to get it in a releasable state without breaking changes.
