Why Clean Architecture?
Maintainability: Changes in one layer won't lead to a domino effect of changes throughout the codebase.
Testability: Each layer is testable in isolation, making it easier to ensure your code works as expected.
Scalability: You can swap out components without disrupting the entire system. It grows with your project!
Adaptability: Technology evolves, but your core business logic remains intact. Upgrades are smoother and less painful.
Layers of Clean Architecture:
- Entity Layer: The core business logic lives here. It represents the heart of your application.
- Use Case Layer: This layer holds application-specific use cases and business rules. It orchestrates interactions between entities and ensures they stay clean and focused.
- Interface Adapters: These adapters bridge the gap between the use cases and the external world, like user interfaces and databases. They keep things flexible and adaptable.
- Frameworks & Drivers: The outermost layer deals with frameworks, tools, and external systems. It's where you connect to databases, APIs, and UI frameworks.
