In this talk we will discuss about building the backend for a web-application using Python and FastAPI. FastAPI is a modern, fast (high-performance), web framework used for building APIs with Python. The session will highlight performing simple CRUD operations using the different endpoints of the API and testing them using pytest. It will focus not only on the concepts but also emphasize on some of the software engineering best practices (patterns and anti-patterns) required to excel in web-development.
