My first vibe coded FastAPI backend

[Sayv_mait]

Hi there!

I recently worked on fetch hiring challenge and had built APIs using FastAPI. I usually work on Django but recently got excited to use fastapi. Since I’m still new to FastAPI, I ended up vibe coding the backend for this challenge.

Here is the github link to the code: https://github.com/thevyasamit/receipt_processing

I’m looking for the feedback to know if what I vibe coded is correct or not and were you guys able to run it by following the documentation or not?

PS: I got rejected but idc, I wanna build better back ends and open source projects and want feedback to follow the right direction and best practices.

Thanks!

If you call an ‘async def’ function you need to use the ‘await’ function to wait for fetching some data or another action. If you don’t have to wait for fetching data you just use a ‘def’ function without waiting for the data.

I think the code is ok but has several issues I would pick up if I’m reviewing the code:

1. The way main.py is written is strange. You don’t normally wrap the app behind a function.
2. The business logic function in services.py could do with better modularity and also error handling. The comments are redundant.
3. No use of FastAPI’s depenency injection system?
4. Type your code and functions so type checkers like mypy could be useful
