1# FastAPI Project Templates
2 
3Production-ready FastAPI project structures with async patterns, dependency injection, middleware, and best practices for building high-performance APIs.
4 
5## When to Use This Skill
6 
7- Starting new FastAPI projects from scratch
8- Implementing async REST APIs with Python
9- Building high-performance web services and microservices
10- Creating async applications with PostgreSQL, MongoDB
11- Setting up API projects with proper structure and testing

13## Core Concepts

15### 1. Project Structure
16 
17**Recommended Layout:**

19```

21├── api/                    # API routes
22│   ├── v1/
23│   │   ├── endpoints/
24│   │   │   ├── users.py
25│   │   │   ├── auth.py
26│   │   │   └── items.py
27│   │   └── router.py
28│   └── dependencies.py     # Shared dependencies
29├── core/                   # Core configuration

33├── models/                 # Database models
34│   ├── user.py
35│   └── item.py
36├── schemas/                # Pydantic schemas
37│   ├── user.py
38│   └── item.py
39├── services/               # Business logic
40│   ├── user_service.py
41│   └── auth_service.py
42├── repositories/           # Data access
43│   ├── user_repository.py
44│   └── item_repository.py
45└── main.py                 # Application entry

48### 2. Dependency Injection
49 
50FastAPI's built-in DI system using `Depends`:
51 
52- Database session management
53- Authentication/authorization
54- Shared business logic
55- Configuration injection
