Declares the props of Inertia pages. mix typelizer.gen writes one TypeScript props interface per page component, and Typelizer.InertiaPage.ValidateProps checks the rendered props in dev and test.

defmodule MyAppWeb.TaskController do
  use MyAppWeb, :controller
  use Typelizer.InertiaPage

  page "tasks/index",
    props: [
      tasks: {:list, MyAppWeb.TaskSerializer},
      filters: :map,
      stats: {:optional, {:object, open: :integer, done: :integer}}
    ]
end

Shared props (added to every page by a plug) are declared once, in one module:

defmodule MyAppWeb.InertiaShared do
  use Typelizer.InertiaPage

  shared current_user: {:nullable, MyAppWeb.UserSerializer}, locale: :string
end
