brpBuild APIs and web apps based on Asynchronous Server Gateway Interface ASGI. This book provides a comprehensive explanation of using Pydantic models to construct the requestresponse objects in a FASTAPI path operation. p pYou'll start by reviewing type hints in Python and the asynchronous processing concepts. One of the highlights of FastAPI is its auto generation of API docs. Pydantic library is the main pillar on top of which FastAPI is built. You'll see that ASGI has a far better performance compared to most of the other popular Python frameworks as they implement Web server Gateway Interface WSGI, which is synchronous in nature and hence having slower response time. p pThis book thoroughly explains how FastAPI interacts asynchronously with relational as well as NOSQL databases. Modern web apps use template engines to interact with the front-end. In this book, you will learn to use jinja2 templates and static assets. Swagger UI and OpenAPI standards are also covered in detail. Fi
