Layered Architecture: Separating API from Business Logic
A layered architecture separates your API into distinct jobs: routing, controlling, and serving. This keeps code maintainable, like an organized toolbox. It's crucial for growing FastAPI apps.
A layered architecture organizes your backend into clear sections, preventing a tangled codebase. In FastAPI, this means a Routing layer maps endpoints, a Controller layer handles the request/response cycle, and a Service layer contains the core business logic. This separation allows you to modify or test one part without breaking others, making your project maintainable as it grows. The common footgun is putting business logic in controllers; they should only delegate work to the service layer, acting as simple request handlers.
