Layered Architecture
Organize production FastAPI projects with a layered architecture — routers, services, repositories, and models — with a full directory tree.
Service Layer Pattern
Implement a service layer in FastAPI that encapsulates business logic, orchestrates repositories, and keeps route handlers thin.
Environment and Settings Management
Manage FastAPI application configuration with pydantic-settings — environment variables, .env files, secret validation, and environment-specific overrides.
