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.

Chapter 5: Structuring FastAPI Applications

In the last four chapters, we looked at the basic steps involved in understanding FastAPI and creating a FastAPI application. The application that we have built so far is a single-file todo application that demonstrates the flexibility and power of FastAPI. The key takeaway from the preceding chapters is how easy it is to build an application using FastAPI. However, there is a need for proper structuring of an application with increased complexity and functionalities.

Structuring refers to the arrangement of application components in an organized format, which can be modular to improve the readability of the application’s code and content. An application with proper structuring enables faster development, faster debugging, and an overall increase in productivity.

By the end of this chapter, you will be equipped with the knowledge of what structuring is and how to structure your API. In this chapter, you’ll be covering...
