Hi everyone

I recently published a small utility library called ash_req_opt, and I wanted to share it here in case it might be useful for others building with Ash Framework.

What is it?

ash_req_opt is a DSL shortcut for declaring attributes and relationships in Ash resources with commonly used allow_nil? and public? options.

Ash is powerful, but sometimes writing repetitive attribute or belongs_to definitions with the same flags gets a bit tedious. This library simplifies that by providing macros like req, opt, req_belongs_to, etc.

Example

defmodule MyApp.User do
  use Ash.Resource, extensions: [AshReqOpt]

  attributes do
    uuid_primary_key :id

    req :email, :string
    req_prv :password_hash, :string
    opt :name, :string
    opt_prv :last_login_at, :utc_datetime

    # fallback to native Ash DSL still works
    attribute :nickname, :string, allow_nil?: true
  end

  relationships do
    req_belongs_to :company, Company
    req_prv_belongs_to :created_by, User
    opt_belongs_to :manager, User
    opt_prv_belongs_to :updated_by, User

    belongs_to :department, Department, allow_nil?: true
  end
end

It’s a small layer, but I hope it helps others too. Feedback, feature suggestions, or improvements are welcome!
