A deterministic composition of PhoenixAssets.Plugin integrations.

A preset is a module that lists integrations; at compile time they are resolved into an ordered plugin graph and exposed via plugins/0. Because resolution happens at compile time, a dependency cycle or a missing hard dependency is a compile error in the preset module.

Example

defmodule MyApp.Assets.Stack do
  use PhoenixAssets.Preset

  integration PhoenixAssets.SvelteKit
  integration PhoenixAssets.Tailwind, entry: "src/app.css"
  integration PhoenixAssets.Storybook, port: 6006
  integration PhoenixAssets.Electric, shapes: MyApp.Assets.ElectricShapes
  integration PhoenixAssets.PubSub, topics: MyApp.Assets.PubSubTopics
  integration PhoenixAssets.Localize, locales: ~w(en sv), default_locale: "en"
end

plugins/0 returns the resolved {module, opts} list. The built-in PhoenixAssets.Presets.Svelte is one such preset; its graph begins with the SvelteKit integration the others build on:

iex> [{first, _opts} | _] = PhoenixAssets.Presets.Svelte.plugins()
iex> first
PhoenixAssets.SvelteKit
