Having trouble with signalR: Connection ID is coming back as undefined when using an angular 5

Having some trouble retrieving the connection ID value after initializing my connection to the SignalR server (using start()) within the .done scope. Despite my efforts, I keep receiving 'undefined' for it. Any assistance in identifying the issue would be greatly appreciated. Thank you!

  public establishConnection(): void
  {
      this.connection = $.hubConnection('http://localhost:62752');
      this.proxy = this.connection.createHubProxy('ChatHub');
      this.proxy.on('messageReceived', (a,b,c,d,e,f) => 
          this.onMessageReceived(a,b,c,d,e,f));

      this.connection.start().done((data: any) => {
          console.log('Connected to Chat Hub');
          this.connectionID = $.connection.hub.id;
          console.log($.connection.hub.id);//undefined
          this.registerConnection();         
      });
  }

Answer №1

Spending extra time dissecting the issue paid off as I finally managed to resolve it! I stumbled upon the realization that the ID can be accessed through data["id"].

  • I named the parameter for the completed function as "data".

Hoping this solution proves valuable to others in similar predicaments, especially since my search on Google yielded no results.
