In this hands-on tutorial you’ll build a production-grade FastAPI app from scratch—covering GET/POST routes, Pydantic models, database connections, and seamless image/video uploads with ImageKit. You’ll get step-by-step timestamps, sample code on GitHub, and deep dives into error handling, status codes, and more.Next, power up your API with user authentication (JWT tokens, protected endpoints), logging, and even a Streamlit frontend. Bonus: check out DevLaunch for personalized mentorship to go beyond tutorials and actually ship real-world projects.
