SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides production-grade FastAPI patterns, including Pydantic v2 schemas, async SQLAlchemy integration, and JWT authentication, to help teams build robust APIs quickly.

Core Features & Use Cases

  • Domain-based project structure and scalable routing patterns with FastAPI
  • Async I/O for database and HTTP calls using SQLAlchemy 2.0
  • JWT authentication and dependency injection for secure endpoints
  • Use Case: Build modular, production-grade API services with clear separation of concerns

Quick Start

Initialize a FastAPI project with uv, add required dependencies, and run the server to see the auto-generated API docs.

FAQPage Schema
What's the best way to structure a production-grade FastAPI project?

Production-grade FastAPI project structure uses domain-based routing and modular architecture to enforce separation of concerns. This pattern separates schemas from models to ensure scalable API services and code maintainability.

How do I implement async database access with SQLAlchemy 2.0 in FastAPI?

FastAPI async database access with SQLAlchemy 2.0 uses async I/O for database and HTTP calls. This pattern supports scalable API services by enabling non-blocking database operations within your routes.

Can I use Pydantic v2 for type-safe configuration and validation in FastAPI?

FastAPI uses Pydantic v2 to provide type-safe configuration and Pydantic-driven validation. It enforces strict schemas for incoming data, ensuring robust APIs with reliable request parsing and response serialization.

How do I add JWT authentication and dependency injection to FastAPI routes?

FastAPI JWT authentication uses dependency injection to secure endpoints across routes. This pattern provides comprehensive security for modular APIs by validating tokens before processing requests.

Do I need to use uv to initialize a FastAPI project?

You can initialize a FastAPI project using uv to add required dependencies and run the server. This quick start setup allows you to quickly see the auto-generated API docs and verify your environment.
