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.

Preface

FastAPI is a fast and efficient web framework for building APIs with Python. This book is a thorough guide on how to build an application with the FastAPI framework.

It starts with the basics of the FastAPI framework and the other technologies used throughout this book. You’ll then learn about the different aspects of the framework: the routing system, response modeling, error handling, and templating.

In this book, you will learn how to build fast, efficient, and scalable applications in Python with FastAPI. You will begin from a Hello World application to a complete API that uses a database, authentication, and templates. You will learn how to structure your application to enhance efficiency, readability, and scalability. By integrating with other libraries in your application, you will learn how to connect your application to both a SQL database and a NoSQL database, integrate templates, and build authentication. Toward the end of this book, you will learn how to write tests, containerize your application, build a continuous integration and delivery pipeline using GitHub actions, and deploy your application to multiple cloud services. All of these will be taught via a theoretical and practical approach.

By the end of this book, you’ll be equipped with the necessary knowledge to build and deploy a robust web API using the FastAPI framework.
