Prefetch server-side query data in Next.js by using a server query client to fetch data on the server, then dehydrate and pass it through a HydrationBoundary to client components. This shares fetched data safely between server and client.

Hydration issues occur when server and client query data do not match. Establishing request-scoped query client ownership and using HydrationBoundary prevents cross-request contamination and ensures the client cache matches the server-rendered output.

Prevent cross-request contamination in Next.js SSR by using a request-scoped server query client. This isolates query cache ownership per request, ensuring data from one request does not leak into another during server-side rendering.

Yes, storefront-data works with getServerQueryClient and dehydrate in Next.js. You coordinate these with preset query options like getListQueryOptions or getDetailQueryOptions to prefetch and bind data for hydration.

The best way to hydrate a prefetched product list is to fetch it using a server query client, dehydrate the cache, and wrap your client components in a HydrationBoundary to pass the server state down without refetching.
