Again a great video about Blazor! Thanks very much! I´d like to know how is an elegant way in terms of UX/UI to deal with the Blazor reconnect message when the SignalR is down?

So you can handle that with js.

Why without Identity? Just curious what you want to do.

@@CoderFoundry Well I do not want to use Identity Server, We prefer Database First and We have bunch of Custom Business Logics to perform before allowing a User to Register or Login.

Gotcha, we will be releasing a video on identity using your own db. So, there is no indentity server. We use this all the time in mvc. However, we are waiting on the final version in October before releasing that repo.

Is there any way to get access to the page's SignalR hub connection object? For instance in the Count example I would like to keep the button disabled until the web socket connection is established, and then enable the button.

@CoderFoundry 5 ай бұрын

Hook into the onAfterRender method. The signalR connection is comelete when it runs. I am setting disabled to false when this completes. Which enables the button. Click me @code { private int currentCount = 0; private bool IsDisabled = true; protected override void OnAfterRender(bool firstRender) { if (firstRender) { IsDisabled = false; StateHasChanged(); } }....

If am correct in the video you just shown server side render mode but not the actual signalR implementation in blazor like in real time data updates in two browser windows !

@CoderFoundry 9 ай бұрын

It's a signalR connection. There is no js to open the modal. The dom state is maintained on the server. The dom is updated via a signalR connection. So if you are talking about something like push notifications like a chat window between to clients . That would be a different problem that can be achieved with signalR.

Doesn't signalR connection uses more resource on server? compared to normal http request response cycle. Also does it require us to use redis backplane to store connection data, if we add multiple servers behind a Load balancer for scalability?

I think those questions would depend on what the site does. I think Blazor client side will be the way to go for larger sites. It will use web api backend to communicate over http. I think the multiple render modes is the real strength of the framework. Specifically, the auto mode allows for client side and siglnar render modes for the same component.
