[Configuration] Is painful to configure working through proxy

[avengerweb]

For example, I wanna use nginx and proxy both API and Web, but currently I need change configurations in webpack and some other places to do that, but I only want: api -> localhost:3001 -> proxy -> api.test-domain.com:80 web -> localhost:3000 -> proxy -> test-domain.com

But when I try to do that without any changes, my browser start try do request to localhost:3000 / localhost:3001
