Not bad problem, not that hard, but not that easy either.

it was third day of vibe coding....

This bitch yesterday, was using one single react component for editing and creating some entity. And it got cycled for 1 hour into same loop:
- both edit and create forms are sending “POST”, request, so edit actually creates new entity
- next cycle point, is when it just sends 2 POST requests for single create forms. Now editing form is correct

And it was for one hour.

Was using Vs code copilot, agent mode, sonnet4.
After some time, I explicitly asked to switch to 2 forms, and separately fixed them.

Besides that switched to sonnet4.5, it was much better.


Why vscode copilot? - cause for last week as Ms employee, it is free for me😁

Happy Saturday. Today is beautiful hard problem, actually can be solved with bruteforce (in some sense), but has gentle optimized solution.
Not bullshit, great hints, great editorial.
