Simple declarative DSL

A taste of how to configure Ash

Below are some examples of the way you can model your resources with actions, attributes and relationships. You can easily swap data layers between Postgres or ETS for example, or add your own data layer extension. Once you've modelled your resources, you can derive GraphQL or JSON API external APIs from them.
