🚀 FastAPI vs Rails — Notes from a Rails Developer Learning FastAPI

#python #rails #ruby #fastapi

I recently explored FastAPI alongside my usual Rails work and built a small project to learn the essentials:

✅ CRUD APIs (with items)
✅ User authentication with JWT (login & registration)
✅ Integrated a Weather API wrapper
✅ DB operation, I use sqlite3
✅ Hands-on with Alembic migrations & SQLModel
✅ Password hashing
✅ Handling Environment variables
and a few more things...

The learning curve was smooth, and I like how FastAPI makes API development clean. 🚀

Here’s the repo if you’d like to take a look 👇

Would love feedback and ideas on what to add next!

To help myself memorize and compare, I drafted this write-up. Hopefully, it helps anyone else coming from Rails into FastAPI.

🔑 Key Comparisons

I am planning to explore for Background jobs anf file upload. I’ll keep updating this as I learn more. If you’re also coming from Rails, maybe this cheat sheet will help!
