How to Tell If Your Code Is Actually Production-Ready

Описание: 💡 Learn how to design great software in 7 steps: https://arjan.codes/designguide.

Your code works locally: you’ve tested the endpoint, the numbers add up, and everything looks fine in the terminal. But is it really ready for production? In this video, I take a small FastAPI app that “just works” and walk you through the key steps to make it production-ready. You’ll learn how to add validation, logging, rate limiting, configuration management, proper database handling, error handling, deployment with Docker, and more.
