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.

Part 1: An Introduction to FastAPI
Part 2: Building and Securing FastAPI Applications
Part 3: Testing And Deploying FastAPI Applications

Chapter 9: Deploying FastAPI Applications

In the last chapter, you learned how to write tests for API endpoints created in a FastAPI application. We started by learning what testing means and walked through the basics of unit testing using the pytest library. We also looked at how to eliminate repetition and reuse test components with fixtures and then proceeded to set up our test environment. We wrapped up the last chapter by writing tests for each endpoint and then testing them alongside checking the test coverage reports after testing.

In this chapter, you’ll learn how to deploy your FastAPI application locally using Docker and docker-compose. A brief section is also added with external resources to deploy your application on serverless platforms of your choice.

In this chapter, we’ll be covering the following topics:

  • Preparing for deployment
  • Deploying with Docker
  • Deploying Docker images
