SignalR's $.hubConnection() is not a function

问题

Hi All i'm working on Implementing a SignalR Stock Ticker Using AngularJS based on an example over here. But i'm getting an error while connecting to signalr like this TypeError: $.hubConnection is not a function

And this is where the error is showing:

var initializeClient = function () {
      //Creating connection and proxy objects
       console.log("anil");
       connection = $.hubConnection();
       //console.log("anil.r");
       proxy = connection.createHubProxy('stockTicker');

       configureProxyClientFunctions();

       start();
        };

Since I'm new to working on signalr , have got lots of confusion in it can anybody help me out of this .

1. npm install -s signalr

2. Add the next lines to angular-cli.json

   "scripts": [
   
   ...
   "../node_modules/signalr/jquery.signalR.js"
   
   ],

1. Make sure it is added, if your project version Angular 6+ add the next lines to angular.json

2. Re-compile project.

   "scripts": [

   ...

   "node_modules/jquery/dist/jquery.js",

   "node_modules/signalr/jquery.signalR.js"

   ],
