Structuring a Laravel app with Clean Architecture involves separating code into Domain, Application, Infrastructure, and Presentation layers. This isolates business logic from Eloquent and framework dependencies, creating a modular, testable, and maintainable codebase.

Refactoring a legacy Laravel app toward a maintainable structure requires applying SOLID principles to decouple business logic from the framework. This involves migrating code into Domain and Application layers, ensuring your core logic remains framework-agnostic and highly testable.

Clean Architecture integrates with Laravel features by confining Eloquent, Service Container, Queues, Events, and API Resources to the Infrastructure and Presentation layers. This keeps the Domain and Application layers framework-agnostic while still leveraging Laravel's built-in utilities.

Yes, you need a solid understanding of SOLID principles and framework-agnostic design to apply Clean Architecture in Laravel. This foundational knowledge is required to correctly decouple dependencies, structure layers properly, and build scalable PHP APIs.

Building scalable APIs in Laravel with Onion or Hexagonal Architecture involves wrapping your core Domain logic in Application use cases, independent of Infrastructure. This dependency inversion allows your API endpoints to remain modular and easily testable as the system scales.
