API Documentation With Swagger And Redoc – FastAPI Beyond CRUD (Part 21)

In this video, we explore API documentation with FastAPI, we look at how it automatically generates detailed API docs using Swagger UI and ReDoc. FastAPI leverages Python type hints and Pydantic models to produce an OpenAPI specification, which forms the backbone of the documentation.

We’ll explore how Swagger UI offers an interactive interface for your API endpoints directly in the browser, while ReDoc provides a clean, customizable layout for documentation. The tutorial includes a live demo where we set up a FastAPI project and demonstrate how the documentation tools work, along with customization options for titles, descriptions, and metadata.
