Any Elixir resources for framework agnostic architectures?

Very good points overall @MrDoops, but I’d like to offer one clarification.

@MrDoops

A big shared kernel we have in the ecosystem are Ecto Changesets. Phoenix uses Ecto Changeset for Phoenix HTML. There’s a trade-off of dependencies but we get benefits of surfacing errors from changesets and reducing a lot of work. The mutual dependency is probably fine since Ecto is a well-established and stable open source project, but it’s there none-the-less.

phoenix_html defines a protocol called FormData and implements it for Ecto.Changeset to minimize that coupling. I don’t believe F# has protocols, so it wasn’t an option in the book. Elixir copied that idea from Clojure.
