How to include a Typescript file in an Angularjs Nativescript project?

Question

JavaScript

I want to add a file but I get an error

        public  static articles=[1,2,3,4,5];
} 

export {GlobalDataClass};

import {GlobalDataClass} from "Data"

@Component({
    selector: "Home",
    moduleId: module.id,
    templateUrl: "./home.component.html",
    styleUrls: ['./home.component.css']
})
export class HomeComponent implements OnInit {

    public articles= GlobalDataClass.articles;

    ngOnInit(): void { 
    }

}

VS Code does not throw an error. Everything is as in the descriptions of the articles. Only I can't get the data in the application.
What could be the reason?
