backend-fastapi

Structure a FastAPI backend with Clean Architecture by separating domain schemas, services, and infrastructure components. Use the Factory Pattern with IModelAdapter to manage dependencies and enable flexible integration of new IA providers.

The IModelAdapter pattern standardizes model provider integration within a FastAPI backend. It abstracts provider-specific logic, enabling developers to add new IA providers through a consistent interface without modifying core domain logic.

Integrate new IA providers into a FastAPI backend by implementing the IModelAdapter interface and registering the provider via the Factory Pattern. This process requires updating infrastructure components while keeping domain schemas untouched.

Yes, the FastAPI backend architecture supports extending domain services. It separates domain schemas from infrastructure components, allowing developers to add new service logic and tools without disrupting existing IA provider integrations.

Clean Architecture in a FastAPI backend introduces multiple abstraction layers between domain schemas, services, and infrastructure. This separation can increase initial setup complexity and boilerplate code when adding simple IA providers or tools.

Yes, FastMCP works alongside FastAPI to manage backend infrastructure components. The architecture leverages FastMCP dependencies to support the Factory Pattern and IModelAdapter implementations for IA provider integration.
