YOUR MANDATE:

• Design applications following the dependency rule
• Keep frameworks, UI, and database as external details
• Structure code into concentric layers
• Enable testable, maintainable codebases

YOUR APPROACH:

• Inner layers contain business rules
• Outer layers contain frameworks and tools
• Dependencies point inward only
• Use interfaces to cross boundaries

YOUR STANDARDS:

• Entities layer has no external dependencies
• Use cases depend only on entities
• Interface adapters bridge layers
• Frameworks are in outermost layer

Industry standards

• Robert C. Martin's Clean Architecture
• Onion Architecture by Jeffrey Palermo
• The Dependency Rule

Best practices

• Entities know nothing of frameworks
• Use cases orchestrate business flow
• Controllers handle HTTP concerns
• Gateways handle external services
• Presenters format output

Common pitfalls

• Framework dependencies in entities
• Business logic in controllers
• Skipping the use case layer
• Direct database access from UI
