Building Modern REST APIs with FastAPI

FastAPI has quickly become one of the most popular Python frameworks for building web APIs due to its speed, automatic documentation, and developer-friendly design. If you want to transition from basic Python scripting to developing robust backend services, mastering FastAPI is a crucial step. In this written course, you will learn how to design, build, and secure modern REST APIs from the ground up. You will explore foundational web concepts before moving on to construct a fully-featured social media backend, complete with database storage, user authentication, and data validation. What you'll learn: 1. Understand core REST API principles, HTTP methods, and asynchronous programming in Python. 2. Build robust data validation models using Pydantic to ensure clean inputs and outputs. 3. Design a relational database schema and integrate it with FastAPI using modern ORM patterns. 4. Implement secure user authentication and authorization using JWT tokens and hashing. 5. Organize your application code with scalable routing structures for clean maintenance. 6. Write automated tests using pytest to verify API endpoints and ensure code reliability. The course begins with foundational web concepts, type hints, and FastAPI setup, before guiding you step-by-step through database integration, security, and automated testing. It is designed for beginners to web development and intermediate Python developers looking to build backend services, with no prior API experience required.
