BFF sample to show notifications on back-channel logout

[brockallen]

For the scenario where the customer wants to do some push notification to the client (e.g. SignalR).

Any update on this expected in the near future? I'm trying to implement a .NET 7 BFF with Vue.js and SignalR. Unfortunately, my Google searches have come up empty in terms of how to replace IUserTokenStore as suggested in another issue.

Any news so far? Some docs would be really helpful, I'm a bit lost.

I use BFF 2.2.0 with server side sessions and it seems like SignalR just works with default cookie-based auth (with no config on SignalR JS client side at all), seems like over WS as expected. According to people, it should not. Maybe my BFF is misconfigured?

I also tried to move SignalR client to WebWorker where the cookie is not easily accessible and switch to JWT auth, don't even know how to start with BFF.

I too would really appreciate more guidance on how to use the (very desirable) Duende BFF framework with a .NET 8 Blazor Web App that contains both Server Side Rendered pages and WASM (no pre-rendering in my case) rendered pages. The WASM pages have a SignalR connection to the server to give real-time client site updates to the server and push server updates to the browser; note: not for the .NET framework itself (it is a multi-player card game app).

I understand that SignalR authenticates at connection set-up, and then not ever again. If necessary for security I could add logic to have the server ask the client to disconnect/reconnect from/to the server Hub when its authorization window expired, but this does feel rather hacky :-(.

Are there any examples of such a setup? If given sufficient guidance I would not mind building a simple demo and give that to Duende for others to look at (once reviewed by Duende for stupid security flaws obviously).

Thanks
