// When running in development/hot mode we load the renderer js code via webpack dev server, and it is from there that
// we ultimately initate requests to these remote resources. The end result is that the electron browser window makes a
// request to localhost (to webpack dev server), which in turn makes a request to the remote resource. If the remote
// resource in question has a restrictive `Access-Control-Allow-Origin` header, this may cause the electron browser
// window to not allow loading the remote content.
//
// See https://enable-cors.org/
//
// In order to mitigate the CORS issue, we instead access these remote resources through a local proxy that we have
// defined on the webpack dev server.
