VS Blazor Server App Template: Server to Client SignalR Communication-CodePudding

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?

CodePudding user response：

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);
      }
}
