What You Will Learn in This Book

Master the fundamentals of FastAPI and modern API design, understanding the evolution of web services and why high-performance, developer-friendly frameworks like FastAPI are essential today.
Set up an optimized FastAPI development environment, including virtual environments, essential tools, and recommended project structures for robust application development.
Build powerful API endpoints by skillfully handling path and query parameters, processing diverse request bodies (JSON, form data, file uploads), and managing various response types.
Implement robust data validation and serialization using Pydantic, ensuring data integrity for both incoming requests and outgoing responses.
Leverage FastAPI's dependency injection system to manage shared logic, streamline authentication, and enhance the testability and modularity of your applications.
Secure your APIs by integrating various authentication mechanisms like Basic Auth, OAuth2 with JWTs, and API keys, and apply essential security best practices.
Handle errors and exceptions gracefully, customizing error responses and implementing effective strategies for a better user experience and easier debugging.
Implement middleware to intercept and modify requests and responses, enabling functionalities like CORS, GZip compression, and custom request processing.
Offload time-consuming tasks using FastAPI's built-in background tasks and understand when to integrate more robust solutions like Celery for asynchronous processing.
Structure large-scale FastAPI applications using APIRouter and recommended architectural patterns for maintainability, scalability, and collaboration.
Integrate and interact with various databases, including synchronous and asynchronous SQLAlchemy, ORMs like Tortoise ORM, and NoSQL databases like MongoDB.
Write comprehensive tests for your FastAPI applications using pytest and TestClient, covering unit tests, integration tests, and dependency overrides.
Explore advanced API features such as WebSockets for real-time communication, Server-Sent Events, and how to customize the OpenAPI schema for enhanced documentation.
Optimize the performance of your FastAPI applications, identifying bottlenecks, applying caching strategies, and configuring Uvicorn/Gunicorn for maximum efficiency.
Containerize your applications with Docker and Docker Compose, preparing them for consistent deployment across different environments.
Strategically deploy your FastAPI APIs to cloud platforms, including PaaS, container orchestration services like Kubernetes, and serverless functions.
Implement robust CI/CD pipelines using tools like GitHub Actions, automating testing, building, and deployment processes.
Set up comprehensive monitoring, logging, and alerting for your production APIs, ensuring observability and quick response to issues.
Navigate the broader FastAPI ecosystem of complementary libraries, community resources, and stay informed about future trends in API development.
