From 1388b81d0e87e1006f676fb1e83fbb48221e4adf Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Fri, 23 May 2025 07:16:15 +0000 Subject: [PATCH] Fix: Correct 'use cache' directive placement in Shopify lib This commit resolves the Vercel build error: "Error: The 'use cache' directive must be at the top of the function body." The following functions in `lib/shopify/index.ts` were updated to ensure that if they use Next.js caching, the `'use cache';` directive is the very first statement in the function body, preceding any conditional logic for dummy data mode: - `getCollection` - `getCollectionProducts` - `getCollections` - `getProduct` - `getProducts` - `getProductRecommendations` Additionally, dummy data mode handling was added to `getProductRecommendations` to align with other data fetching functions. Functions fully converted to dummy data providers (like `getMenu` and `getCart` when in dummy mode) were confirmed to not use these directives, which is correct. --- lib/shopify/index.ts | 99 ++++++++++++++++++++++++-------------------- 1 file changed, 55 insertions(+), 44 deletions(-) diff --git a/lib/shopify/index.ts b/lib/shopify/index.ts index 2abe2748d..262e540d4 100644 --- a/lib/shopify/index.ts +++ b/lib/shopify/index.ts @@ -13,10 +13,10 @@ import { import { cookies, headers } from 'next/headers'; import { NextRequest, NextResponse } from 'next/server'; import { - addToCartMutation, // Needed for live addToCart - createCartMutation, // Needed for live createCart - editCartItemsMutation, // Needed for live updateCart - removeFromCartMutation // Needed for live removeFromCart + addToCartMutation, + createCartMutation, + editCartItemsMutation, + removeFromCartMutation } from './mutations/cart'; // import { getCartQuery } from './queries/cart'; // No longer needed for dummy getCart import { @@ -29,7 +29,7 @@ import { import { getPageQuery, getPagesQuery } from './queries/page'; import { getProductQuery, - getProductRecommendationsQuery, + getProductRecommendationsQuery, // Ensure this is imported getProductsQuery } from './queries/product'; import { @@ -40,23 +40,23 @@ import { Menu, Page, Product, - ShopifyAddToCartOperation, // Needed for live addToCart + ShopifyAddToCartOperation, ShopifyCart, - // ShopifyCartOperation, // No longer needed for dummy getCart + ShopifyCartOperation, // Needed for live getCart ShopifyCollection, ShopifyCollectionOperation, ShopifyCollectionProductsOperation, ShopifyCollectionsOperation, - ShopifyCreateCartOperation, // Needed for live createCart + ShopifyCreateCartOperation, // ShopifyMenuOperation, // No longer needed for dummy getMenu ShopifyPageOperation, ShopifyPagesOperation, ShopifyProduct, ShopifyProductOperation, - ShopifyProductRecommendationsOperation, + ShopifyProductRecommendationsOperation, // Needed for live getProductRecommendations ShopifyProductsOperation, - ShopifyRemoveFromCartOperation, // Needed for live removeFromCart - ShopifyUpdateCartOperation, // Needed for live updateCart + ShopifyRemoveFromCartOperation, + ShopifyUpdateCartOperation, Money, ProductOption, ProductVariant, @@ -218,7 +218,6 @@ const reshapeProducts = (products: ShopifyProduct[]) => { return reshapedProducts; }; -// Define a shared default dummy cart structure const DEFAULT_DUMMY_CART: Cart = { id: 'dummy-cart-id-123', checkoutUrl: '/cart-checkout', @@ -283,11 +282,9 @@ export async function createCart(): Promise { if (process.env.NEXT_PUBLIC_USE_DUMMY_DATA === 'true') { console.log('createCart: Called in DUMMY DATA MODE.
