The ADR (Action/Domain/Responder) pattern offers a clean alternative to fat controllers in Laravel by splitting request handling into three distinct responsibilities. The Action serves as a thin HTTP entry point, the Domain encapsulates business logic independently of transport concerns, and the Responder translates domain results into HTTP responses. A practical article publishing example demonstrates how to implement each layer using invokable controllers, result objects with status enums, and dedicated responder classes. The pattern improves testability by allowing isolated unit tests per layer, and makes maintenance easier since each layer changes for a single reason.
