Completes the migration started in f8c3ef9. That commit put hydrogen
underneath the existing shopifyFetch wrapper; this one removes the
wrapper so every query uses the package's own client API.
- All 22 call sites now call storefront.graphql(DOCUMENT, { variables })
(cachedStorefront for shop policies) instead of shopifyFetch, which
emulated the old client's {query, variables} -> {data} shape.
- shopifyFetch is replaced by unwrapStorefrontResult(result, operation),
which is only an error policy, not a transport wrapper: it returns
data and throws when Shopify reports GraphQL errors, since hydrogen
returns those rather than throwing. Naming the operation means a
failure points at the call site instead of just at "Shopify".
- Environment reads move to services/shopify/config, so client.ts is
only the hydrogen clients and shop-pay-button no longer imports from
a query module just to get the store domain.
- Removes @shopify/storefront-api-client, the superseded client. It had
no importers.
The SHOPIFY_STOREFRONT_API_URL export is gone too — hydrogen builds the
endpoint from storeDomain and apiVersion, and nothing else used it.
No behaviour change intended: same documents, same env var names, same
2025-07 API pin, same caching split between the two clients.
yarn typecheck passes with 0 errors. Verified against mock.shop: build
prerenders the policy pages, and in the browser product grid, search,
collection filters, cart restore, quantity update and discount-code
apply all work with no console errors. Customer account flows remain
untested — they need real credentials.
