Client Side Deep Links with WebpackDevMiddleware 404s

[NotMyself]

I have an asp.net core app that is using spa services to serve up a vue.js client-side application. When running in Development mode with the WebpackDevMiddleware enabled, all client-side deep links return a 404.

How can I configure the fall back routes for the WepackDevMiddleware?

To Reproduce

Steps to reproduce the behavior:

1. Clone the repository: https://github.com/NotMyself/bivrost.git
2. Switch branches: git checkout adding-client-side-routing-and-storage
3. Open in Visual Studio Code
4. Comment out lines 35-36 in Startup.cs to prevent TwitchBot from trying to connect.
5. Run the .NET Core Launch (web) debugger
6. Note that the route: http://localhost/ serves up the vue app with HMR enabled
7. Enter the URL directly into the address bar: http://localhost/overlays/chat
8. Note the app throws a 404.

Expected behavior

I expect the spa application to be served up on client side routes.

@ryanbrandenburg can you please look into this? Thanks!

Feel free to reach out to me if you need anything @ryanbrandenburg. I have kind of moved on with development, but the branch is the same.

Thanks for contacting us, @NotMyself.
After looking into this a bit more it seems this is purely a question which you'll get a faster answer from StackOverflow using the asp.net-core-mvc tag.

Giving it a try. Will see what happens. If anyone googles and finds my question here, my StackOverflow question can be found here.
