Bug: Backend default port conflicts with Vite dev server (both 5173)

[Siddh2024]

Bug

In server/index.js:51-56, the server defaults to port 5173 which is the default Vite dev server port. Running both the backend and Vite frontend simultaneously causes port conflicts.

Impact

Cannot run both frontend and backend concurrently without manual config changes.

Fix

Change the backend default port to a non-conflicting port like 3001 or 4000.

Hi @DeadIndian,

I would like to work on this bug under GSSoC 2026.

I reviewed the issue and identified that the backend default port conflicts with the Vite development server port. I can fix the configuration by assigning a non-conflicting default backend port while maintaining environment variable compatibility.

I will ensure the change is properly documented and tested in the local development environment.

Kindly assign this issue to me.

Thank you!
