Use the ChatJS React Query v5 lazy-prefetch pattern without blocking server rendering. Use when prefetching tRPC queries in Next.js Server Components or changing query dehydration and hydration behavior in apps/chat.

We split this skill into the rules it gives an agent

2 rules. About 0 are common, 1 is distinctive, and 1 is very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈1

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Start optional server prefetches early without awaiting them so they can stream through React hydration without blocking rendering.

    line 8
  2. Very specific:

    Use the exported prefetch() helper from @/trpc/server: prefetch(trpc.foo.bar.queryOptions(...)).

    line 10

≈ “Common” is an estimate: at least 1 in 5 of the 308,232 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Lazy prefetch pattern

Start optional server prefetches early without awaiting them so they can stream through React hydration without blocking rendering.

  • Use the exported prefetch() helper from @/trpc/server: prefetch(trpc.foo.bar.queryOptions(...)). It handles both paginated and non-paginated queries.
  • Await only data required before rendering.
  • Render through the existing HydrateClient or HydrationBoundary.

This depends on trpc/query-client.ts dehydrating pending queries and using SuperJSON for serialization and hydration. Preserve those settings when using this pattern.

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
