FastAPI Foundations: Build Secure APIs with TDD and PostgreSQL

Modern web applications demand fast, secure, and reliable backend APIs. FastAPI has emerged as a leading Python framework for building high-performance APIs quickly and efficiently. This written course guides you from backend basics to designing and building robust APIs. You will learn how to structure your projects using modern Python practices, secure your endpoints with JSON Web Tokens, and write automated tests to ensure your code works flawlessly before it ever goes live. What you'll learn: - Understand the core concepts of FastAPI, asynchronous programming, and modern Python type hints. - Build fully functional CRUD endpoints for data management and blog systems. - Implement secure user authentication using hashed passwords and JWTs stored in HttpOnly cookies. - Apply Test-Driven Development principles using Pytest to write reliable unit tests. - Configure a PostgreSQL database to store and retrieve application data efficiently. - Design interactive API documentation automatically using built-in OpenAPI specifications. The course starts with foundational backend concepts and FastAPI setup, gradually progressing through database integration, security implementations, and comprehensive testing strategies. You will learn by reading structured explanations and studying clear, real-world code snippets. This course is designed for beginners who want to learn backend development and API design. No prior experience with FastAPI or database management is required, though a basic understanding of Python is helpful. Start reading today to build your first high-performance, industry-standard API.
