FastAPI in 2025: Building Lightning-Fast Python APIs with Automatic Documentation and Type Safety

Abstract: FastAPI has emerged as the go-to framework for high-performance Python API development, processing over 3,000 requests per second while maintaining developer productivity. This talk explores FastAPI's game-changing features including automatic OpenAPI documentation generation, built-in data validation through Pydantic, and native async/await support that rivals Node.js and Go performance.
Key topics include FastAPI's modern Python type hint integration, automatic interactive documentation (Swagger UI/ReDoc), advanced security features, and testing strategies.
