FastAPI Expert

Skill Verified Active

Use when building high-performance async Python APIs with FastAPI and Pydantic V2. Invoke to create REST endpoints, define Pydantic models, implement authentication flows, set up async SQLAlchemy database operations, add JWT authentication, build WebSocket endpoints, or generate OpenAPI documentation. Trigger terms: FastAPI, Pydantic, async Python, Python API, REST API Python, SQLAlchemy async, JWT authentication, OpenAPI, Swagger Python.

Purpose

To guide developers in building robust, high-performance, and secure asynchronous Python APIs using FastAPI and Pydantic V2, covering the full development lifecycle from schema design to deployment.

Features

  • Create REST endpoints with FastAPI
  • Define Pydantic V2 validation schemas
  • Implement JWT authentication and authorization
  • Set up async SQLAlchemy database operations
  • Build WebSocket endpoints
  • Generate OpenAPI documentation

Use Cases

  • Building new async Python APIs with FastAPI.
  • Refactoring existing APIs to use FastAPI and Pydantic V2.
  • Implementing secure authentication flows for Python APIs.
  • Setting up robust data validation using Pydantic models.
  • Integrating async database operations with SQLAlchemy.

Non-Goals

  • Building non-Python APIs.
  • Using synchronous Python frameworks.
  • Implementing basic synchronous database operations.
  • Providing generic API security advice outside the context of FastAPI/Python.

Workflow

  1. Analyze requirements for API endpoints, data models, and authentication needs.
  2. Design Pydantic V2 schemas for data validation.
  3. Implement asynchronous API endpoints using FastAPI and dependency injection.
  4. Secure the API with authentication, authorization, and rate limiting.
  5. Write asynchronous tests using pytest and httpx.
  6. Verify OpenAPI documentation at /docs.
