Documentation-First Development with FastAPI

Explore the concept of Documentation-First Development (DFD) with FastAPI in this 37-minute conference talk from EuroPython 2024. Discover how to leverage FastAPI's code-based OpenAPI documentation generation capabilities to maintain up-to-date API documentation. Learn about implementing a sub-application pattern for segregating API documents and using generic types to create reusable custom response models. Understand the limitations of traditional API documentation approaches and see how FastAPI, combined with Pydantic, offers a solution for automatically synchronizing documentation with code. Gain practical insights into creating precise, well-maintained API documentation and learn about the benefits of using FastAPI for web development projects.
