const navigationStrategy = new NetworkFirst({
  cacheName: "cached-navigations",
});

const navigationRoute = new NavigationRoute(navigationStrategy, {
  // Optionally, provide a allow/denylist of RegExps to determine
  // which paths will match this route.

  // denylist: [],
});

serwist.registerRoute(navigationRoute);
