Preface

FastAPI is a web framework for building APIs with Python 3.6 and its later versions based on standard Python type hints. With this book, you’ll be able to create fast and reliable data science API backends using practical examples.

This book starts with the basics of the FastAPI framework and associated modern Python programming concepts. You’ll then be taken through all the aspects of the framework, including its powerful dependency injection system and how you can use it to communicate with databases, implement authentication, and integrate machine learning models. Later, you will cover the best practices relating to testing and deployment to run a high-quality, robust application. You’ll also be introduced to the extensive ecosystem of Python data science packages. As you progress, you’ll learn how to build data science applications in Python using FastAPI. The book also demonstrates how to develop fast and efficient machine learning prediction backends. For this, you’ll be taken through two projects covering typical use cases of AI: real-time object detection and text-to-image generation.

By the end of this FastAPI book, you’ll have not only learned how to implement Python in data science projects but also how to maintain and design them to meet high programming standards with the help of FastAPI.
