Want to build fast, modern, and practical web APIs with Python?

FastAPI in Practice by Thomas Avery is a hands-on guide for Python developers who want to move beyond basic examples and learn how to build structured, reliable APIs with FastAPI.

Instead of overwhelming you with theory, this book takes a practical approach. You'll gradually build your understanding of FastAPI while learning the essential skills needed to create real-world API applications-from your first endpoint to database integration, authentication, testing, Docker, and deployment.

Inside this book, you'll learn how to:

• Build your first FastAPI application from scratch

• Create routes, endpoints, and HTTP operations

• Work with path and query parameters

• Validate incoming data with Pydantic

• Design clean and consistent API responses

• Organize FastAPI projects for maintainability

• Connect FastAPI applications to databases

• Implement complete CRUD operations

• Understand asynchronous programming with async and await

• Add authentication and protect API endpoints

• Handle errors and application dependencies

• Write automated tests with Pytest

• Use middleware and background tasks

• Containerize FastAPI applications with Docker

• Prepare APIs for production deployment

• Apply practical security, performance, and maintenance practices

Whether you're learning FastAPI for the first time or already have Python experience and want to build better APIs, this book provides a clear path from fundamentals to practical application development.

You'll follow concepts as they are introduced, apply them through practical examples, and gradually assemble the pieces into a more complete API application.

FastAPI in Practice is designed to help you stop simply reading about APIs and start building them with Python.

If you're ready to turn your Python skills into modern web APIs, this book gives you a practical place to start.
