View Source Ash.Api.Dsl (ash v2.15.0)
Apis are the entrypoints for working with your resources.
Apis may optionally include a list of resources, in which case they can be
used as an Ash.Registry in various places. This is for backwards compatibility,
but if at all possible you should define an Ash.Registry if you are using an extension
that requires a list of resources. For example, most extensions look for two application
environment variables called :ash_apis and :ash_registries to find any potential registries
