Refactoring a fat controller involves extracting validation and business logic into a service layer and moving data access into a repository. This Skill guides that transformation to output clean controllers with dependency injection wiring for PHP and TypeScript projects.

The service and repository pattern separates concerns by moving data access into repositories and rules into services. This creates thin controllers that handle HTTP requests, resulting in improved testability and easier maintenance for monolithic codebases.

Yes, this service layer refactoring approach applies to codebases in both PHP and TypeScript projects. It guides the extraction of queries and rules from monolithic controllers to generate modular, testable service and repository classes.

The best way to set up dependency injection is by wiring the repository into the service and the service into the controller. This Skill provides scalable skeletons and guidance for dependency injection to ensure clean separation of concerns.

Moving data access queries into a separate repository hides data access details from the controller. This separation enables easier testing of business logic in the service layer without direct database dependencies, simplifying maintenance.
