clean-architecture

Refactoring legacy services involves enforcing strict dependency boundaries to isolate database-specific logic and framework annotations from core domain logic. This ensures business rules remain independent of technical infrastructure through rigorous dependency inversion.

The dependency rule in clean architecture mandates that dependencies point inward toward domain entities. It works by ensuring outer layers like frameworks and adapters depend on inner use cases, never the reverse, maintaining long-term software maintainability.

Evaluating module layers for clean architecture compliance requires analyzing existing modules and dependencies to verify adherence to the dependency rule. This process identifies tight coupling between business logic and technical infrastructure.

Clean architecture works with Kotlin and domain-driven-design by providing a structured framework for creating decoupled layers. It facilitates domain entities, application use cases, and technical adapters while keeping business logic independent.

Dependency inversion in software design is needed when preventing tight coupling between business logic and technical infrastructure. It becomes essential for maintaining long-term software maintainability as systems evolve and acquire framework dependencies.

The best way to structure decoupled layers is by separating domain entities, application use cases, and technical adapters. This design guidance ensures business logic remains independent of frameworks, databases, and UI implementations through dependency boundaries.
