FastAPI Project Templates

Production-ready FastAPI project structure with async patterns, dependency injection, and layered architecture.

- Provides recommended directory layout separating API routes, models, schemas, services, and repositories for maintainable codebases

- Includes base repository pattern for generic CRUD operations and service layer for business logic encapsulation

- Demonstrates async/await patterns throughout, from database sessions to route handlers, with proper lifespan management and middleware setup

- Covers authentication via JWT tokens, password hashing with bcrypt, and dependency-based authorization checks on protected endpoints

- Includes async testing patterns with pytest fixtures for in-memory SQLite and dependency override for isolated unit tests
