Building Python Web APIs with FastAPI

By: Abdulazeez Abdulazeez Adeshina

Overview of this book

RESTful web services are commonly used to create APIs for web-based applications owing to their light weight and high scalability. This book will show you how FastAPI, a high-performance web framework for building RESTful APIs in Python, allows you to build robust web APIs that are simple and intuitive and makes it easy to build quickly with very little boilerplate code. This book will help you set up a FastAPI application in no time and show you how to use FastAPI to build a REST API that receives and responds to user requests. You’ll go on to learn how to handle routing and authentication while working with databases in a FastAPI application. The book walks you through the four key areas: building and using routes for create, read, update, and delete (CRUD) operations; connecting the application to SQL and NoSQL databases; securing the application built; and deploying your application locally or to a cloud environment. By the end of this book, you’ll have developed a solid understanding of the FastAPI framework and be able to build and deploy robust REST APIs.

Summary

In this chapter, we learned how to add SQL and NoSQL databases using SQLModel and Beanie respectively. We made use of all our knowledge from the previous chapters. We also tested the routes to ensure that they are working as planned.

In the next chapter, you will be introduced to securing your application. You will first be taught the basics of authentication as well as the various authentication methods available to FastAPI developers. You will then implement an authentication system that relies on JSON Web Token (JWT) and secure the routes to create, update, and delete events. Lastly, you will modify the route, to create events to allow the linking of events to a user.
