Adopt Clean Architecture Pattern
Context
We need to establish a scalable and maintainable architecture for the ModernAPI template that will serve as a foundation for enterprise applications. The architecture should support long-term maintainability, testability, and allow for easy extension and modification.
Problem Statement
Traditional layered architectures often lead to tight coupling between business logic and external dependencies, making the code harder to test and maintain. We need an architecture that: - Keeps business logic independent from external concerns - Makes the system highly testable - Supports easy integration of new features - Provides clear separation of responsibilities
Rationale
Clean Architecture provides the best balance of maintainability, testability, and long-term flexibility. The dependency rule ensures that business logic remains pure and testable, while the clear layer separation makes the codebase easier to understand and modify. Although it requires more initial setup, the long-term benefits outweigh the costs, especially for a template intended for enterprise use.
