# FastAPI Project Templates Production-ready FastAPI project structures with async patterns, dependency injection, middleware, and best practices for building high-performance APIs. ## When to Use This Skill - Starting new FastAPI projects from scratch - Implementing async REST APIs with Python - Building high-performance web services and microservices - Creating async applications with PostgreSQL, MongoDB - Setting up API projects with proper structure and testing ## Core Concepts ### 1. Project Structure **Recommended Layout:** ``` app/ ├── api/ # API routes │ ├── v1/ │ │ ├── endpoints/ │ │ │ ├── users.py │ │ │ ├── auth.py │ │ │ └── items.py │ │ └── router.py │ └── dependencies.py # Shared dependencies ├── core/ # Core configuration │ ├── config.py │ ├── security.py │ └── database.py ├── models/ # Database models │ ├── user.py │ └── item.py ├── schemas/ # Pydantic schemas │ ├── user.py │ └── item.py ├── services/ # Business logic │ ├── user_service.py │ └── auth_service.py ├── repositories/ # Data access │ ├── user_repository.py │ └── item_repository.py └── main.py # Application entry ``` ### 2. Dependency Injection FastAPI's built-in DI system using `Depends`: - Database session management - Authentication/authorization - Shared business logic - Configuration injection ### 3. Async Patterns Proper as...
