Aspnetcore SignalR 1.0.0-rc1-final: not working RRS feed

  • Question

  • User-920806005 posted

    Hi everyone, I'm using signalr for simple real-time chat application.

    Previously I installed version 1.0.0-preview1-final (both client and server side) and chat application worked.

    Now I updated them to 1.0.0-rc1-final; results: I can't connect to server.
    Here it is my client-side code.

    import signalR, { HubConnection, HubConnectionBuilder } from '@aspnet/signalr';
    
    ...
    
    ...
    
      const connection = new signalR.HubConnectionBuilder()
      .withUrl("http://localhost:53965/chat")
      .build();
    
    connection.on("send", data => {
      console.log(data);
    });
    
    connection.start()
    .then(() => connection.invoke("send", "Hello"))
    .catch(() => console.log("error"));

    I get the error "Unable to get property 'HubConnectionBuilder' of undefined or null reference".
    So, i removed signalR. before HubConnectionBuilder, and i get these errors: 1-Failed to complete negotiation with the server: Error. 2-Failed to start the connection: Error

    Any ideas to solve this problem?

    Hi Pasto92,

    Based on your hub server project, I do a test with my SignalR JavaScript client app, and my SignalR JavaScript client can communicate well with your hub server, so your hub server project has been upgraded to 1.0.0-rc1-final successfully.

    If your client app can not communicate with your hub server, perhaps the SignalR JavaScript client library does not install well for your client app.  

    With Regards,
