API

class HashLocationStrategy extends LocationStrategy implements OnDestroy {
  constructor(_platformLocation: PlatformLocation, _baseHref?: string | undefined): HashLocationStrategy;
  onPopState(fn: LocationChangeListener): void;
  getBaseHref(): string;

  prepareExternalUrl(internal: string): string;
  pushState(state: any, title: string, path: string, queryParams: string): void;
  replaceState(state: any, title: string, path: string, queryParams: string): void;
