export const API_PORT = 3033

This would be great to have, especially for windows users as that port sometimes gets blocked by something. I manually reconfigured the port and built locally and haven't had the issue since.

This would be perfect, in my company the port 3033 is blocked, and it's imposible to use masscode here.

Thanks!
