FastAPI for Beginners: Building High-Performance Python APIs

Python developers need a modern, high-performance framework to build scalable web services, and FastAPI provides speed, automatic validation, and excellent documentation out of the box. By the end of this course, you will be able to design, implement, test, and secure production-ready APIs using FastAPI, Pydantic, and asynchronous database connections. What you'll learn: * Understand foundational concepts of RESTful architecture and synchronous versus asynchronous programming in Python. * Master API routing, dependency injection, and data validation using Pydantic models and standard Python type hints. * Implement user authentication and authorization flows using secure token-based methods. * Configure and interact with databases asynchronously for efficient data persistence. * Practice writing unit and integration tests for API endpoints using the built-in TestClient and the pytest framework. The course begins with core API definitions and environment setup, progressing through routing, data modeling, dependency management, and concluding with essential security and testing practices. This course is designed for beginner Python developers who want to start building modern web backends. No prior experience with web frameworks is required.
