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.
Table of Contents (14 chapters)
Part 1: An Introduction to FastAPI
Part 2: Building and Securing FastAPI Applications
Part 3: Testing And Deploying FastAPI Applications


In this chapter, you learned how to prepare your application for deployment. You started by updating the dependencies used for the application and saving them in the requirements.txt file before moving on to managing the environment variables used for the API.

We also covered the steps involved in deploying an application to production: building the Docker image from the Dockerfile, configuring the compose manifest for the API and database services, and then deploying the application. You also learned new commands to check the list of running containers as well as start and stop Docker containers. Finally, you tested the application to ensure the deployment was successful.

This marks the end of this book, and you should now be ready to build, test, and deploy a FastAPI application on the web. We covered various concepts and ensured that each concept is properly discussed with adequate examples: routing, templating, authentication, connecting to the database, and deploying...
