I am importing a class to another class and I want to access its non-static property in Angular but I am unable to do that.
Here is the code that I am using:
Websocket.config.ts
export class WebSocketConfig implements OnInit{
    auth$: Subscription;
    userInfo: UserInfo;
    user_name: string;
    username: string;
    constructor(private authService: AuthorizationService){
    }
    ngOnInit() {
        this.username = this.getUserName();
    }
    getUserName(): string{
        this.auth$ = this.authService.getUserInformation().subscribe(result => {      
            this.userInfo = result;
            this.user_name = this.userInfo.user_id;
          });
          return this.user_name;
    }
    public static uri: string = "wss://localhost:9093/powerme-notification-websocket/websocket";
    public static notification_topic : string = '/user/topic/releaseLock';
}
shared.module.ts
    const stompConfig : StompConfig = {
      url : WebSocketConfig.uri,
      headers: {client_id: WebSocketConfig.username},
      heartbeat_in: 0,
      heartbeat_out: 20000,
      reconnect_delay: 5000,
      debug: false
}
In the WebSocketConfig.username, It says that "Property username does not exist on type "typeOf WebSocketConfig".
I am using Stomp and websocket for sending notifications.
