Laravel Controllers

Thin HTTP layer: controllers contain zero domain logic, only HTTP concerns.

Core Concept

controllers.md - Complete controller guide:

• Zero domain logic in controllers
• Web layer vs public API distinction
• Invokable controller pattern
• Query objects for filtering/sorting
• Proper delegation to actions
• Response patterns

Pattern

final readonly class CreateOrderController
{
    public function __invoke(
        CreateOrderRequest $request,
        CreateOrderAction $action,
    ): RedirectResponse {
        $order = $action($request->toDto());

        return redirect()->route('orders.show', $order);
    }
}

Controller responsibilities:

• HTTP request/response transformation
• Routing to appropriate action
• Authentication/authorization checks (via middleware/policies)
• Nothing else

Domain logic lives in actions.
