useStorefront((storefront) => {
const rateAndReviewApi = await storefront.getApi('rateAndReviewApi');
const hasBeenReviewed$ = rateAndReviewApi.selectHasBeenReviewed$("145");
hasBeenReviewed$.subscribe((hasBeenReviewed) => {
if (hasBeenReviewed) {
// do something if product has been reviewed
}
if (!hasBeenReviewed) {
// do something if product has not been reviewed
}
});
});
