Setting up SPA on a subpath in an existing ASP.Net gRPC app

[keith-miller]

Hello! So I have an existing ASP.Net gRPC app with transcoding enabled. I just wrote a React SPA that works fine in development because Vite is listening on a separate port and is a separate process. Since gRPC needs to be listening on the base route, I wanted to set up route mapping that would serve the SPA in a subpath, but I can't seem to figure out the correct settings to do so. Any help would be great.

Thanks!
