""` fallbacks in `buildCurrentProduct()` -- `useSelector` mock in tests must use delegation pattern `(...args) => mockUseSelector(...args)` not direct `jest.fn()` — esbuild import hoisting requires this -- Test file must use `/** @jest-environment jsdom */` docblock (not `//` single-line comment) for jsdom environment - -#### Phase 2 Complete -- All 10 items implemented and tested (958 tests pass, 38 suites) -- Build succeeds via `yarn build` (tsdx) in ~10 minutes -- Dependencies installed: `@elasticpath/catalog-search-instantsearch-adapter@0.0.5` (exact-pinned), `react-instantsearch@^7.26`, `react-instantsearch-nextjs@^0.3`, `instantsearch.js@^4.90` -- Adapter uses default export pattern: `require("...").default` — creates `new CatalogSearchInstantSearchAdapter({ client })` which exposes `.searchClient` -- All components use dynamic `require()` for react-instantsearch hooks to avoid hard dependency at build time when in design mode -- `import { type X }` inline syntax NOT supported by tsdx's TypeScript — must use separate `import type { X }` statements -- Zod 3.25.x has breaking type changes vs @hookform/resolvers — fixed with `as any` cast on `zodResolver(bundleSchema)` call -- Mock data uses "sample-cs-" prefix IDs, distinct from Phase 1 "sample-pd-" and Phase 3 "sample-rp-" prefixes -- `EPSearchHits` normalizes hits via `normalizeHitToCurrentProduct()` with fallback field patterns for EP catalog search adapter output - -#### Phase 3 Complete -- All 4 items implemented and tested (918 tests pass, 37 suites) -- Build succeeds via `yarn build` (tsdx) -- `useRelatedProducts` hook calls `getByContextAllRelatedProducts` from `@epcc-sdk/sdks-shopper` — SDK function confirmed available -- Hook lives at `src/product-discovery/use-related-products.tsx` (not `src/product/` as originally planned — collocated with the provider for module coherence) -- `SWR_DEDUPING_INTERVAL_LONG` imported from `../const` (root `src/const.ts`), NOT `../utils/const.ts` (which doesn't exist) -- EPRelatedProductsProvider uses inner component pattern (`EPRelatedProductsProviderInner`) to avoid conditional hook calls in preview branches -- Provider exposes both `productGridData` (shared D4 key for EPProductGrid reuse) and `relatedProductsData` (relationship-specific metadata) -- Mock data: 4 distinct products with `sample-rp-*` IDs, separate from Phase 1 `sample-pd-*` listing mocks -- Auto-reads product ID from parent `currentProduct` DataProvider context; overridable via `productId` prop - -#### Post-Completion Fixes (2026-03-08) -- **EPSearchHits currencyCode fix**: Was hardcoded to "USD" — now reads from parent `catalogSearchData` DataProvider context via `useSelector("catalogSearchData")?.currencyCode`, falling back to "USD" -- **RelatedProductsData relationshipName**: Added `relationshipName: string` field to `RelatedProductsData` interface per spec. Added `relationshipName` prop to `EPRelatedProductsProvider` (default "Related Products") so designers can set human-readable labels for section headings. Mock data updated. -- Test count: 962 tests pass (38 suites) — 4 new tests added for the above fixes - -### No Skipped/Flaky Tests, No Relevant TODOs - -- Searched all test files — no `.skip()`, `xit()`, `xdescribe()`, `xtest()` patterns -- Only TODOs found are in checkout (address validation) and site (use-brands stub) — both unrelated -- No `FIXME` patterns found - -### Existing Utilities Available for Reuse - -- `src/utils/normalize.ts` — `normalizeProduct()` and `normalizeProductFromList()` (convert EP SDK → commerce types) - - `normalizeProductFromList()` accepts optional `included` object with `main_images` and `files` arrays - - Price: reads `meta.display_price.without_tax`, divides by 100 (EP stores cents) - - Images: resolved from `included.main_images[]` and `included.files[]` -- `src/utils/formatCurrency.ts` — `formatCurrency(amount, currencyCode)` using `Intl.NumberFormat`; also `formatCurrencyFromCents(amountInCents, currencyCode)` -- `src/utils/design-time-data.ts` — Mock data infrastructure (`MOCK_` prefix pattern) -- `src/utils/get-sort-variables.ts` — Sort string mapping (`price-asc` → `price asc`, etc.) -- `src/product/use-search.tsx` — Reference for `getByContextAllProducts` SDK call pattern (returns `{ products, found }`, no pagination) -- `src/utils/errorHandling.ts` — `EPErrorCode` enum, `createEPError()`, `handleAPIError()`, `formatUserErrorMessage()` -- `src/utils/getEPClient.ts` — Type-safe `getEPClient(provider)` extraction of EP SDK client -- `src/utils/const.ts` — `DEFAULT_CURRENCY_CODE = 'USD'`, SWR deduping intervals - -### Data-Fetching Pattern (Confirmed) - -All standalone data-fetching hooks use **`useMutablePlasmicQueryData`** from `@plasmicapp/query` (peer dependency). NOT raw SWR. Examples: -- `inventory/use-stock.tsx` — `useMutablePlasmicQueryData, Error>(queryKey, fetcher, { revalidateOnFocus: false, dedupingInterval })` -- `inventory/use-locations.tsx` — Same pattern with location-specific query key -- `bundle/use-bundle-option-products.tsx` — Batches 100-product chunks in single SWR call -- `bundle/use-parent-products.tsx` — Two-phase fetch within single SWR call - -All return `{ data, loading, error, refetch: () => mutate() }` shape. - -### EP SDK Pagination API (Confirmed) - -`getByContextAllProducts` query params (typed as `BigInt`): -- `page[limit]` — max records per page (up to 100) -- `page[offset]` — zero-based offset by record count (max 10,000) - -Response pagination metadata at `response.data?.meta`: -```typescript -meta: { - results?: { total?: BigInt } // total matching products - page?: { - limit?: BigInt, // records per page - offset?: BigInt, // current offset - current?: BigInt, // current page number - total?: BigInt // total records - } -} -``` +## Items To Implement (Prioritized) -**Note:** Must convert `number` → `BigInt` when passing to SDK: `BigInt(pageSize)`, `BigInt(page * pageSize)`. +### Phase 0: ShopperContext Foundation (P0) — 9 Items -### Reference Implementation Patterns +- [ ] **P0-1: ShopperContext component** — `src/shopper-context/ShopperContext.tsx` + - GlobalContext providing override channel for cart identity + - Symbol.for singleton pattern (matching BundleContext.tsx, CartDrawerContext.tsx) + - Props: cartId, accountId, locale, currency + - Tests: renders children, provides overrides, empty when no props -All new components follow the **headless Provider → Repeater** pattern: -- **Provider pattern:** `bundle/composable/EPBundleProvider.tsx` (DataProvider, refActions, previewState, slots, design-time mock with no-op actions) -- **Repeater pattern:** `bundle/composable/EPBundleComponentList.tsx` (repeatedElement(), nested DataProvider per item, `role="listitem"` wrapper) -- **Context singleton:** `bundle/composable/BundleContext.tsx` (Symbol.for + globalThis for multi-instance safety) -- **Cart drawer pattern:** `cart-drawer/EPCartDrawer.tsx` (DataProvider + module-level store, NO separate React Context needed when actions are via refActions) -- **Registration:** `index.tsx` (registerAll, import order: fields first → repeaters → providers) -- **Mock data:** `utils/design-time-data.ts` and `bundle/composable/design-time-data.ts` (MOCK_ prefix, covers all preview states, typed interfaces) -- **Registration function:** Each component exports `register*()` accepting optional `loader` + `customMeta` overrides -- **Design-time detection:** `usePlasmicCanvasContext()` + `previewState` prop (auto|withData|empty|loading|error) -- **State binding:** `states: { isOpen: { type: "writable", variableType: "boolean", valueProp, onChangeProp } }` for bidirectional Plasmic state +- [ ] **P0-2: useShopperContext hook** — `src/shopper-context/useShopperContext.ts` + - Hook to read current ShopperContext overrides + - Returns {} when no provider above ---- +- [ ] **P0-3: useShopperFetch hook** — `src/shopper-context/useShopperFetch.ts` + - Fetch wrapper that attaches X-Shopper-Context header when overrides present + - Omits header when no overrides (production browsing) + - Tests: header attached/omitted correctly -## Architectural Decisions +- [ ] **P0-4: Server resolve-cart-id** — `src/shopper-context/server/resolve-cart-id.ts` + - parseShopperHeader() + resolveCartId() — header > cookie > null + - Framework-agnostic (works with any Node.js request) + - Tests: priority resolution, malformed header handling -### D1: New hook instead of modifying `use-search.tsx` +- [ ] **P0-5: Server cart-cookie** — `src/shopper-context/server/cart-cookie.ts` + - buildCartCookieHeader() + buildClearCartCookieHeader() + - No dependency on `cookie` package — builds string directly + - Tests: valid httpOnly cookie string, clear cookie string -The existing `use-search.tsx` returns `{ products, found }` via the base `SearchProductsHook` type from `@plasmicpkgs/commerce`. Extending that type would modify the upstream package. Per merge strategy, create a **new** `use-product-list.tsx` hook that calls `getByContextAllProducts` directly with pagination support. This follows the same pattern as `EPBundleProvider` calling `useBundleConfiguration` directly. +- [ ] **P0-6: Server barrel** — `src/shopper-context/server/index.ts` + - Exports from resolve-cart-id.ts and cart-cookie.ts -~~Item 1.1 (Enhance use-search.tsx)~~ → Replaced by Item 1.1 (Create use-product-list hook). +- [ ] **P0-7: Client barrel** — `src/shopper-context/index.ts` + - Exports ShopperContext, useShopperContext, useShopperFetch -### D2: Compute `price.formatted` at DataProvider level +- [ ] **P0-8: Registration** — `src/shopper-context/registerShopperContext.ts` + `src/index.tsx` + - Create registerShopperContext.ts with shopperContextMeta and register function + - Registration name: `plasmic-commerce-ep-shopper-context` + - Props: cartId (string), accountId (string, advanced), locale (string, advanced), currency (string, advanced) + - Add import/call in registerAll() in src/index.tsx, after registerCommerceProvider + - Add `export * from './shopper-context'` to src/index.tsx -The base `ProductPrice` type has `value` and `currencyCode` but NOT `formatted`. Rather than modifying `normalize.ts` or the base commerce types, compute `formatted` when building the `currentProduct` object in EPProductGrid/EPSearchHits: +- [ ] **P0-9: Constants** — `src/const.ts` + - Add EP_CART_COOKIE_NAME = 'ep_cart' + - Add SHOPPER_CONTEXT_HEADER = 'x-shopper-context' -```typescript -const formatted = formatCurrency(product.price.value, product.price.currencyCode); -``` +### Phase 1: Cart Read Hooks (P1) — 5 Items -This avoids modifying any upstream files. ~~Item 1.2 (Add formatted to normalize.ts)~~ → Folded into EPProductGrid (Item 1.4). +- [ ] **P1-1: useCart hook** — `src/shopper-context/use-cart.ts` + - SWR hook fetching GET /api/cart via useShopperFetch + - Cache key includes cartId when present (Studio refetch) + - Types: CartItem, CartMeta, CartData, UseCartReturn + - Tests: fetch call, SWR key varies with cartId, error handling -### D3: No separate React Context needed for product list +- [ ] **P1-2: useCheckoutCart hook** — `src/shopper-context/use-checkout-cart.ts` + - Wraps useCart, normalizes to CheckoutCartData (formatted prices, itemCount, currency) + - Types: CheckoutCartItem, CheckoutCartData + - Tests: normalization, null handling, formatted prices -The EPCartDrawer pattern demonstrates that DataProvider + refActions is sufficient when the repeater (grid) only needs to read data and actions are invoked via Plasmic interactions. A separate `ProductListContext.tsx` adds unnecessary complexity. The `useProductList` hook manages all state internally; EPProductListProvider exposes it via DataProvider + refActions. +- [ ] **P1-3: Design-time mock data** — `src/shopper-context/design-time-data.ts` + - MOCK_SERVER_CART_DATA: CheckoutCartData with 2 items, realistic prices -~~Item 1.4 (ProductListContext.tsx)~~ → Removed. State lives in hook, exposed via DataProvider. +- [ ] **P1-4: EPCheckoutCartSummary enhancement** — `src/checkout/composable/EPCheckoutCartSummary.tsx` + - Add optional `cartData` prop — when provided, skip internal fetch, use external data + - Non-breaking: existing behavior preserved when prop not provided + - Tests: external data rendered, internal fetch still works -### D4: Shared DataProvider key for EPProductGrid parent flexibility +- [ ] **P1-5: Update barrel exports** — `src/shopper-context/index.ts` + - Add useCart, useCheckoutCart, design-time data exports -EPProductGrid needs to work inside both EPProductListProvider (Phase 1) and EPRelatedProductsProvider (Phase 3). Rather than try/fallback on multiple selector names, **both providers write products to a shared key `productGridData`** via DataProvider: +### Phase 2: Cart Mutation Hooks (P2) — 4 Items -```typescript - -``` +- [ ] **P2-1: useAddItem hook** — `src/shopper-context/use-add-item.ts` + - POST /api/cart/items via useShopperFetch, mutate() after + - AddItemInput type: productId, variantId?, quantity?, bundleConfiguration?, locationId?, selectedOptions? + - Tests: POST call, body shape, mutate called + +- [ ] **P2-2: useRemoveItem hook** — `src/shopper-context/use-remove-item.ts` + - DELETE /api/cart/items/{id} via useShopperFetch, mutate() after + - URL-encodes itemId + - Tests: DELETE call, mutate called + +- [ ] **P2-3: useUpdateItem hook** — `src/shopper-context/use-update-item.ts` + - PUT /api/cart/items/{id} via useShopperFetch, debounced at DEFAULT_DEBOUNCE_MS (500ms) + - Tests: PUT call, debounce behavior, mutate called after debounce + +- [ ] **P2-4: Update barrel exports** — `src/shopper-context/index.ts` + - Add useAddItem, useRemoveItem, useUpdateItem exports + +### Phase 3: Credential Removal (P3) — 5 Items + +- [ ] **P3-1: Deprecate old cart hooks** — `src/cart/*.tsx` + - Add @deprecated JSDoc to use-cart.tsx, use-add-item.tsx, use-remove-item.tsx, use-update-item.tsx + - Add @deprecated to src/utils/cart-cookie.ts (getCartId, setCartId, removeCartCookie) -EPProductGrid always reads `useSelector("productGridData")`. This is cleaner and extensible. Phase 2's EPSearchHits is a separate component (not EPProductGrid) that reads from InstantSearch hooks directly. +- [ ] **P3-2: CommerceProvider serverCartMode** — `src/registerCommerceProvider.tsx` + - Add `serverCartMode` boolean prop (advanced, default false) + - When true + no clientId: skip EP SDK init, render children only + - Existing behavior unchanged when false -**Single key, no duplication.** EPProductListProvider exposes ONE DataProvider key (`productGridData`) containing both the products array AND pagination metadata (currentPage, totalPages, sort, hasNextPage, summary, etc.). Designers bind grid children to `productGridData.products` (via EPProductGrid) and pagination/summary UI to `productGridData.currentPage`, `productGridData.summary`, etc. No separate `productListData` key — that would duplicate data and confuse designers. +- [ ] **P3-3: EPPromoCodeInput server mode** — `src/checkout/composable/EPPromoCodeInput.tsx` + - Add `useServerRoutes` boolean prop + - When true: apply promo via POST /api/cart/promo, remove via DELETE /api/cart/promo + - Existing behavior unchanged when false + +- [ ] **P3-4: Audit and document** — Review all getEPClient() / useCommerce() usage for cart operations + - Confirm all cart paths have server-route alternatives + - Document remaining client-side EP usage (product/search hooks — intentionally kept) -### D5: No `parentComponentName` restriction on EPProductGrid +- [ ] **P3-5: CartActionsProvider review** — Check if global actions (addToCart) need updating + - If used in Plasmic interactions, ensure they work with server-cart hooks + - May need ServerCartActionsProvider or modification to existing one -Since EPProductGrid must work inside multiple parent providers (EPProductListProvider, EPRelatedProductsProvider), do NOT set `parentComponentName` in its registration metadata. Instead, document the expected parent relationship in the `description` field. +--- -Note: The Phase 1 spec (`product-discovery-core.md`) lists `parentComponentName` on EPProductGrid — this is overridden by D5 for Phase 3 compatibility. +## Implementation Order -### D6: Use `useMutablePlasmicQueryData` for data fetching (not raw SWR) +Build strictly in phase order. Within each phase, build in item order. -All standalone data-fetching hooks in this codebase use `useMutablePlasmicQueryData` from `@plasmicapp/query` (a peer dependency that wraps SWR).

charset=UTF-8 Content-Transfer-Encoding: 8bit P3-1: Add @deprecated JSDoc to old client-side cart hooks (use-cart, use-add-item, use-remove-item, use-update-item) and cart-cookie utilities, directing developers to the new server-route alternatives in shopper-context/. P3-2: Add serverCartMode boolean prop to CommerceProvider. When enabled with no clientId, renders children without EP SDK initialization — cart operations use server routes via ShopperContext instead. P3-3: Add useServerRoutes prop to EPPromoCodeInput. When enabled, promo apply/remove go through POST/DELETE /api/cart/promo server routes via useShopperFetch() instead of the client-side EP SDK.
