SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Build production-ready FastAPI applications with modern async stack, including JWT authentication, validation, and database integration.

Core Features & Use Cases

Domain-based project structure with clear separation of concerns (auth, items, etc.)
JWT authentication integration, password hashing, and token handling
Async data handling using SQLAlchemy 2.0 and Pydantic v2 with FastAPI
Guidance for dependency injection, OpenAPI schemas, and error handling
Real-world project blueprint suitable for rapid API development

Quick Start

Create a new FastAPI project with uv, install dependencies for fastapi, sqlalchemy, aiosqlite, python-jose, and passlib, and start the development server.

FAQPage Schema

How do I structure a FastAPI project with JWT authentication and async database integration?▼

FastAPI project structure uses domain-based separation of concerns, integrating JWT authentication, async SQLAlchemy 2.0, and Pydantic v2 to build production-ready APIs. It enforces dependency injection and proper status codes across modular domains like auth and items.

What's the best way to implement async database operations in FastAPI with SQLAlchemy 2.0?▼

Async database operations in FastAPI leverage SQLAlchemy 2.0 and Pydantic v2 for robust validation. The pattern enforces async I/O and dependency injection to ensure scalable data handling and proper separation of concerns.

Does FastAPI work with Pydantic v2 and uv for dependency management?▼

FastAPI works seamlessly with Pydantic v2 and uv. You create a project with uv, install dependencies including fastapi, sqlalchemy, aiosqlite, python-jose, and passlib, and start the development server for rapid API building.

How do I add JWT authentication and password hashing to a FastAPI application?▼

JWT authentication in FastAPI uses python-jose and passlib for password hashing and token handling. It applies dependency injection to secure endpoints and enforce proper validation per best-practice guidelines.

Can I generate OpenAPI schemas and handle errors automatically in FastAPI?▼

FastAPI provides guidance for OpenAPI schemas and error handling. It enforces proper status codes and robust validation per best-practices, generating real-world project blueprints suitable for scalable API development.

When should I use async patterns over sync I/O in FastAPI endpoint design?▼

Async patterns in FastAPI are enforced for scalable API development and robust validation. Use async I/O with SQLAlchemy 2.0 and aiosqlite to maintain clear separation of concerns and handle concurrent data requests efficiently.
