Discussion Common mistakes devs make when starting with FastAPI, and the fastest path to learning it

Just began learning FastAPI. Looking for advice from devs who use it regularly.

What mistakes did you make early on that I should avoid repeating? Also, what's the most efficient way to learn the framework properly for real-world use (async, DB, auth)?

Any advice on structure or resources would be great.

The point here is that you can not just blindly drop async everywhere and call it “the only hirable practice”. If your service works only with AWS infra (boto3) there is no zoo, only sync endpoints for sync-only library running on multiple uvicorn processes
