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. +### SG-1: Form Field Pre-Population After Page Refresh +**Gap:** Surviving form components read from `checkoutData` DataProvider for initial pre-population. After Phase D deletes `EPCheckoutProvider`, `checkoutData` won't exist. +**Decision:** Phase D adds D-4.3 to adapt all 3 form components to also read from `checkoutSession.customerInfo` / `checkoutSession.shippingAddress` / `checkoutSession.billingAddress` when `checkoutData` is absent. -~~Item 1.1 (Enhance use-search.tsx)~~ → Replaced by Item 1.1 (Create use-product-list hook). +### SG-2: Orphaned Hooks After Phase D +**Gap:** `use-checkout.tsx` and `use-stripe-payment.tsx` remain after Phase D. +**Decision:** Leave untouched. `use-stripe-payment.tsx` is used by the legacy `EPPaymentForm` (not in scope for session model). Legacy monolithic components (EPCheckoutForm, EPPaymentForm, EPOrderSummary, EPCheckoutConfirmation) are out of scope. -### D2: Compute `price.formatted` at DataProvider level +### SG-3: Cookie Encryption +**Gap:** Spec says "encrypted JSON in httpOnly cookie" but no crypto dependency existed. +**Decision:** Node.js built-in `crypto` (AES-256-GCM). Encryption key from env var `CHECKOUT_SESSION_SECRET`. -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: +### SG-4: Clover SDK Types +**Gap:** No Clover TypeScript package as a dependency. +**Decision:** Types defined manually in `src/checkout/session/adapters/clover-types.ts`. SDK loaded via script tag at runtime. -```typescript -const formatted = formatCurrency(product.price.value, product.price.currencyCode); -``` +### SG-5: Server-Side Stripe Import +**Gap:** `stripe` (server-side SDK) not in `package.json`. +**Decision:** Added in Phase C (C-1.1). Lazy `require('stripe')` inside the adapter factory avoids pulling it into client bundles. -This avoids modifying any upstream files. ~~Item 1.2 (Add formatted to normalize.ts)~~ → Folded into EPProductGrid (Item 1.4). +### SG-6: Request Object Abstraction +**Gap:** Handlers need a framework-agnostic request/response type. +**Decision:** `SessionRequest` type: `{ body, headers, cookies }`. `SessionResponse` type: `{ status, body, headers? }`. Consumer route files translate their framework's req/res into this shape. -### D3: No separate React Context needed for product list +### SG-7: No CloverError in Error Hierarchy +**Gap:** `error-handling.ts` has `StripeError` but no `CloverError`. +**Decision:** Clover adapter uses `PaymentError` with `details.gateway: "clover"` and gateway-specific `details.code` values. No new class needed. -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. +### SG-8: validateEnvironmentVariables() Only Checks Stripe +**Gap:** Session handlers need to validate `CHECKOUT_SESSION_SECRET` and gateway-specific vars. +**Decision:** Session handlers do NOT call `validateEnvironmentVariables()`. `CookieSessionStore` validates `CHECKOUT_SESSION_SECRET` at construction. Gateway vars validated when adapters are instantiated in consumer's `checkout-config.ts`. -~~Item 1.4 (ProductListContext.tsx)~~ → Removed. State lives in hook, exposed via DataProvider. +### SG-9: Existing stripe Server SDK Missing from package.json +**Gap:** `setup-payment.ts` and `confirm-payment.ts` imported `stripe` without it in `package.json`. +**Decision:** Phase C (C-1.1) adds `stripe` to `package.json`, fixing both the session model need and this pre-existing gap. -### D4: Shared DataProvider key for EPProductGrid parent flexibility +--- -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: +## Key Learnings + +- **tsdx build cache corruption:** `ENOENT` errors during tsdx build → clear `node_modules/.cache`. +- **tsdx inline type imports:** `rollup-plugin-typescript2` does NOT support `import { Foo, type Bar }` syntax. Use separate `import type { Bar }` statements. Fixed in `EPCheckoutSessionProvider.tsx` and all Clover components. +- **Stripe lazy require:** `require('stripe')` inside the adapter factory (not top-level) prevents the Node.js-only SDK from being pulled into client bundles by consumer bundlers. +- **Virtual mock pattern:** `jest.mock("stripe", ..., { virtual: true })` needed when `stripe` may not be physically installed in the monorepo dev environment. +- **esbuild mock pattern:** Use `jest.mock()` at top, then `require()` to get mocked refs (same as Phase A handlers). `jest.spyOn` on `jest.requireActual()` does NOT work with esbuild — use full mock factory instead. +- **`@jest-environment jsdom` docblock:** All test files that need DOM must include `/** @jest-environment jsdom */` as the first docblock line. Root `jest.config.js` defaults to `node`; `jest.config.checkout.js` sets `jsdom`, but `yarn test` runs the root config in CI. +- **`global.fetch` mock setup:** `global.fetch = jest.fn()` must be set before `mockReset()` is called — otherwise `mockReset` throws if fetch is undefined. +- **jest.config.checkout.js testMatch bug:** Original pattern only matched `checkout/` (legacy), NOT `checkout-session/`. Fixed by adding explicit `checkout-session/**` pattern. +- **SWR deduplication:** `EPStripePayment` uses `useCheckoutSession(apiBaseUrl)` internally. SWR deduplicates by key, so it shares cache with `EPCheckoutSessionProvider`. Tests mock `../use-checkout-session` directly instead of SWR. +- **EPStripePayment refAction:** `submitPayment` refAction calls `stripe.confirmPayment()` then `hook.confirmPayment({ paymentIntentId })`. Exposed for designers to wire to a "Pay" button. +- **EPCheckoutSessionProvider DataProvider callbacks:** Includes `updateSession` and `calculateShipping` callbacks so child components (e.g., `EPShippingMethodSelector`) can call mutations without ref access to the provider. +- **`./server` subpath export:** tsdx bundles all JS into the main entry. Server-only code (handlers, `CookieSessionStore`, adapters) can't be in the main entry without pulling Node.js-only deps into client bundles. Solution: separate `build-server.mjs` using esbuild (externalizes all deps) produces `dist/server.js`, mapped via `package.json` `"exports"` to `"./server"`. Consumer imports from `@elasticpath/plasmic-ep-commerce-elastic-path/server`. +- **Consumer route helper pattern:** `lib/checkout-handler.ts` provides `runHandler(req, res, handler)` that adapts Next.js `NextApiRequest` → `SessionRequest`, calls handler, writes `SessionResponse`. All 5 route files are thin wrappers (~15 lines each). +- **EP SDK client pattern:** Handlers use `{ settings: { application_id, host } } as any` for the EP client, matching the existing handler pattern. Not `createShopperClient()`. +- **`EPCloverCardField.tsx`:** Internal shared component created to avoid 4× duplication across card field components. Not referenced in any spec. +- **EP order retry in `/pay`:** When `session.order` already exists (from a previous failed payment attempt), the handler skips `checkoutApi` and reuses the existing order ID. A new `paymentSetup` (authorize) is still created because the previous authorization may have been voided or expired. The double-submit guard (`session.status !== "open"`) prevents concurrent retries; the `failed` case in the adapter result mapping resets status to `"open"` to enable retries. +- **`toHaveClass` / `toHaveTextContent` not available:** Root jest config does not include `@testing-library/jest-dom`. Use plain DOM assertions like `element.className.includes()` and `element.textContent` instead. +- **ShopperContext has no account profile data:** `EPShopperContextProvider` is a GlobalContext providing only `cartId`, `accountId`, `locale`, `currency` overrides — NOT a DataProvider. There is no built-in `shopperContextData` DataProvider with account profile or addresses. +- **`shopperContextData` is consumer-provided:** `EPCustomerInfoFields` and `EPShippingAddressFields` read from `useSelector("shopperContextData")` — any ancestor DataProvider named `shopperContextData` suffices. The EP `ShopperContextProvider` doesn't provide this; it's the consumer's responsibility to add a DataProvider with `{ account: { name, email }, addresses: [...] }` when account data is available. This decouples account management from the checkout components. +- **EPPaymentElements uses CheckoutInternalContext:** The composable EPPaymentElements reads `clientSecret` from `CheckoutInternalContext` (set by EPCheckoutProvider after `setupPayment()`) and exposes the Stripe `elements` instance back through the same context for `confirmPayment` calls. This is distinct from EPStripePayment which reads from session `payment.clientToken`. -```typescript - -``` +--- -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. +## Deferred / Future Work -**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. +Items explicitly called out as deferred in the specs or not in scope for this branch: -### D5: No `parentComponentName` restriction on EPProductGrid +- **Vercel KV session store** — `CookieSessionStore` is the only implementation; KV store is the intended production alternative +- **Webhook-based payment confirmation** — Stripe webhooks (`payment_intent.succeeded`) and Clover webhooks for async confirmation +- **Stripe saved cards / Customer portal** — Stripe `SetupIntent` flow, saved payment methods +- **Stripe Link integration** — one-click Stripe Link checkout +- **Clover saved cards / customer vault** — Clover card vault for returning customers +- **Clover refund/void flows** — post-capture refund and pre-capture void handlers +- **Multi-tender (split payment)** — paying with multiple gateways / gift cards +- **Order confirmation page components** — Plasmic components for the post-checkout confirmation screen +- **Email receipt integration** — triggering transactional email after `complete` status +- **Debounced session sync** — auto-saving form field changes to the session without explicit user action +- **Express / Fastify / Hono route examples** — Consumer spec only documents Next.js Pages Router; other framework adapters are mentioned but not implemented +- **Authentication / rate-limiting middleware for routes** — Consumer route helpers have no auth or rate-limit layer +- **Server-side payment retry rate limiting** — card testing mitigation (referenced in hardening spec) -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. +## Composable Checkout (composable-checkout.md) -### D6: Use `useMutablePlasmicQueryData` for data fetching (not raw SWR) +**Status:** Complete — all 3 phases done -All standalone data-fetching hooks in this codebase use `useMutablePlasmicQueryData` from `@plasmicapp/query` (a peer dependency that wraps SWR).
