Descriptions

FastAPI Mastery: Build Modern APIs with Python, FastAPI Mastery: Build Modern APIs with Python is a comprehensive, hands-on course by Uplatz. FastAPI is a modern, high-performance web framework for building APIs with Python 3.7+, known for its speed, simplicity, and production readiness. The course covers everything from routing, request handling, and data validation with Pydantic, to advanced database integration and JWT authentication. You will learn to build scalable RESTful APIs, manage routes, validate data, handle requests and responses, implement robust error handling, and secure endpoints with authentication. Real-world projects like a To-Do List App and Book Management API are included, giving you practical experience for professional or personal use. The curriculum is designed for Python developers, backend engineers, and data scientists, and covers best practices for production-ready APIs, including error handling, security, and optimization. No prior web framework experience is required, but basic Python knowledge is recommended.

What you’ll learn

Understand the FastAPI framework – Learn its core features, advantages, and how it compares to other frameworks like Flask and Django.
Build and manage routes – Implement RESTful API endpoints using path, query, and parameterized routes.
Leverage Pydantic for validation – Validate and serialize input/output data with Pydantic models.
Work with request bodies and form data – Handle structured JSON inputs, multipart forms, and user-submitted data effectively.
Design response models and status codes – Standardize API responses with FastAPI response models, status codes, and custom schemas.
Implement robust error handling – Capture and return meaningful error messages with structured exception handling.
Integrate databases with FastAPI – Connect APIs to relational or NoSQL databases and perform CRUD operations.
Perform advanced database operations – Manage relationships, transactions, and queries for scalable applications.
Implement authentication – Use basic authentication to secure endpoints.
Work with JWT-based security – Apply JSON Web Token authentication for modern, stateless, and scalable API security.
Develop real-world projects – Build and deploy hands-on applications like a To-Do List API and a Book Management API.
Troubleshoot and optimize APIs – Gain confidence in debugging, testing, and optimizing FastAPI applications for production.
