What problem does it solve?
Building scalable, type-safe, and secure asynchronous Python APIs requires many coordinated decisions: validation, async database patterns, authentication, routing, and documentation. This Skill consolidates best practices and implementation templates so teams avoid common async pitfalls and deliver robust FastAPI services more quickly.
Core Features & Use Cases
- Pydantic V2 schemas and validators for precise, type-safe request and response models.
- Async SQLAlchemy patterns with session management, CRUD examples, and lifecycle handlers for production workloads.
- Authentication & Authorization patterns including JWT creation/verification and role-based access dependencies.
- Routing & WebSockets guidance, APIRouter structuring, dependency injection using Annotated, and OpenAPI documentation practices.
- Testing & Migration examples for async tests with httpx/pytest and migration strategies from Django/DRF.
Quick Start
Use the fastapi-expert skill to scaffold an async FastAPI router with Pydantic V2 schemas, JWT authentication, and async SQLAlchemy CRUD for a User model.
