How to get real-time location of device using web socket with Traccar API in Angular 8?

I was trying to build my own customized web interface in Angular 8, But having issue connecting to Traccar Websocket to get real-time location. Can anyone guide me how to connect Traccar web socket using angular 8. Please suggest any code snippet or any reference as i am new into this.

with RxJs :

import {webSocket, WebSocketSubject} from 'rxjs/webSocket';
myWebSocket: WebSocketSubject = webSocket('ws://localhost:8000');

to get data :

myWebSocket.asObservable().subscribe(dataFromServer => //...);

to send data :

myWebSocket.next({message: 'some message'});
