getting data from TRPC vs Zustand store

const fetchRequestedProduct =
    api.requestedProduct.getRequestedProductByTransactionIdAndProductId.useQuery(
      {
        transactionId,
        productId,
      },
      {
        enabled: requestedProductsInStore.get(productId) === undefined,
      }
    );

  useEffect(() => {
    const requestedProductsFromStore = requestedProductsInStore.get(productId);
    if (requestedProductsFromStore !== undefined) {
      setCurrentRequestedProducts(requestedProductsFromStore);
      return;
    }
    if (fetchRequestedProduct.data) {
      const requestedProducts: RequestedProductForTable[] =
        fetchRequestedProduct.data;
      setCurrentRequestedProducts(requestedProducts);
    }
  }, [
    fetchRequestedProduct.data,
    productId,
    requestedProductsInStore,
    setCurrentRequestedProducts,
  ]);
