Question

Since blazer server already establish a signalr connection with it's client, without creating new signalr connection is there any simple way for server to tap in blazorhub and push notification to client?

Answer 1

Each time you call StateHasChanged the DOM is updated if needed.

You can trigger this update with a timer or with some other events.

public async Task NewMessageAsync(Message message, CancellationToken cancel)
{
      if (_tenant.MessageMatchTemplate(message, _template))
      {
          messagesDisplayList.Add(message.data);
          await InvokeAsync(StateHasChanged);
      }
}
