The simplest HTTP proxy with custom headers

posted in Nodejs on 2020-05-06   proxy headers authorization node local request server req http basic pass

The app runs fine but as soon as it does a fetch request to a local endpoint the request fails with 401 not-authorized error. In the modern browsers that's not happening because the browser kinda knows that we came here with basic auth and automatically includes authorization: basic ... header.
