Overview of this book

Building Data Science Applications with FastAPI is the go-to resource for creating efficient and dependable data science API backends. This second edition incorporates the latest Python and FastAPI advancements, along with two new AI projects – a real-time object detection system and a text-to-image generation platform using Stable Diffusion. The book starts with the basics of FastAPI and modern Python programming. You'll grasp FastAPI's robust dependency injection system, which facilitates seamless database communication, authentication implementation, and ML model integration. As you progress, you'll learn testing and deployment best practices, guaranteeing high-quality, resilient applications. Throughout the book, you'll build data science applications using FastAPI with the help of projects covering common AI use cases, such as object detection and text-to-image generation. These hands-on experiences will deepen your understanding of using FastAPI in real-world scenarios. By the end of this book, you'll be well equipped to maintain, design, and monitor applications to meet the highest programming standards using FastAPI, empowering you to create fast and reliable data science API backends with ease while keeping up with the latest advancements.

Summary

Congratulations! You are now ready to build high-quality FastAPI applications that have been well tested. In this chapter, you learned how to use pytest, a powerful and efficient testing framework for Python. Thanks to pytest fixtures, you saw how to create a reusable test client for your FastAPI application that can work asynchronously. Using this client, you learned how to make HTTP requests to assert the behavior of your REST API. Finally, we reviewed how to test WebSocket endpoints, which involves a fairly different way of thinking.

Now that you can build a reliable and efficient FastAPI application, it’s time to bring it to the whole world! In the next chapter, we’ll review the best practices and patterns for preparing a FastAPI application for the world before studying several deployment methods.
