I'm not sure if i understand your question but if you want to create constants, you can do it in a different class and import it.

constants.ts

export class Constants {
  public static get HOME_URL(): string { return "sample/url/"; };
}

sample.component.ts

   import { Constants } from "./constants";
    @Component({

    })
     export class SampleComponent {
      constructor() {
       let url = Constants.HOME_URL;
      }
    }
