Clean Architecture

Giriş

Clean Architecture, software design'da dependency direction, separation of concerns ve maintainability için kritik öneme sahip bir architectural pattern'dir. Mid-level geliştiriciler için Clean Architecture'i anlamak, scalable, maintainable ve testable software geliştirmek için gereklidir. Bu bölüm, domain layer, application layer, infrastructure layer, presentation layer ve cross-cutting concerns konularını kapsar.

Kapsanan Konular

1. Domain Layer

Business logic, entities, value objects, ve domain services.

Öğrenilecekler: - Domain entities - Value objects - Domain services - Business rules - Domain events

2. Application Layer

Use cases, application services, ve orchestration logic.

Öğrenilecekler: - Use case implementation - Application services - Command/Query separation - Application logic - Service orchestration

3. Infrastructure Layer

External concerns, data access, ve third-party integrations.

Öğrenilecekler: - Data access implementation - External service integration - Configuration management - Logging implementation - Caching implementation

4. Presentation Layer

User interface, API controllers, ve presentation logic.

Öğrenilecekler: - API design - Controller implementation - View models - Presentation logic - User interface

5. Cross-Cutting Concerns

Logging, security, caching, ve configuration management.

Öğrenilecekler: - Cross-cutting concerns - Middleware implementation - Aspect-oriented programming - Configuration management - Security implementation

Neden Önemli?

1. Maintainability

  • Clear separation of concerns
  • Easy to understand
  • Simple to modify
  • Reduced complexity

2. Testability

  • Isolated components
  • Easy to mock
  • Unit testable
  • Integration testable

3. Scalability

  • Modular design
  • Easy to extend
  • Loose coupling
  • High cohesion

4. Team Collaboration

  • Clear boundaries
  • Shared understanding
  • Parallel development
  • Knowledge transfer
