clean-architecture

Clean architecture is a layered architecture pattern that enforces separation of concerns by dividing code into Entities, Use Cases, Interface Adapters, and Frameworks. This structure ensures dependency rules isolate business logic from external frameworks, promoting maintainability and long-term code stability.

To implement dependency inversion and data isolation in your code structure, apply mandatory heuristics that enforce dependency rules across architectural layers. This ensures inner layers like Entities remain independent of outer frameworks, keeping data isolation intact and maintaining a screaming architecture design.

Yes, you can review an existing codebase for adherence to layered architecture principles by applying a structured review checklist. This process analyzes your project's code structure against mandatory heuristics, generating a report that identifies areas for architectural improvement and dependency rule violations.

The best way to structure code independent of frameworks and drivers is to apply the clean architecture pattern. By organizing code into strict layers from Entities to Frameworks, you enforce dependency inversion, ensuring core business rules remain isolated and maintainable regardless of external dependencies.

You should not use clean architecture when your software development project has minimal complexity or requires rapid prototyping. The strict layering, multiple abstraction boundaries, and mandatory heuristics introduce structural overhead that may outweigh the maintainability benefits for small or simple codebases.
