In the SSR guide, we noted that you could get rid of the boilerplate of having `<HydrationBoundary>` in every route. This is not possible with Server Components.

> NOTE: If you encounter a type error while using async Server Components with TypeScript versions lower than `5.1.3` and `@types/react` versions lower than `18.2.8`, it is recommended to update to the latest versions of both. Alternatively, you can use the temporary workaround of adding `{/* @ts-expect-error Server Component */}` when calling this component inside another. For more information, see [Async Server Component TypeScript Error](https://nextjs.org/docs/app/building-your-application/configuring/typescript#async-server-component-typescript-error) in the Next.js TypeScript docs.

Update the TypeScript section fragment.

The linked page now calls this section “With Async Server Components.” The current fragment does not select it, so readers land at the top of the page. Use #with-async-server-components. (nextjs.org)

Update the TypeScript documentation link in the async Server Components note to
use the fragment #with-async-server-components, so it selects the intended
section on the linked page.

> WARNING: We do **not** recommend using Next.js Server Actions to _fetch_ data in a `queryFn`. When called from the client, Server Actions [run serially, not in parallel](https://react.dev/reference/rsc/use-server#caveats), which conflicts with how React Query fetches and refetches queries. This can leave queries stuck in a pending state or cause the action to never run at all (see [#7934](https://github.com/TanStack/query/issues/7934)). Passing a Server Action reference to `queryFn` can also fail with `Only plain objects, and a few built-ins, can be passed to Server Actions...`, since you have to _call_ the action rather than pass it as a reference (see [#6264](https://github.com/TanStack/query/issues/6264)). For fetching data on the client, `fetch` from an API route or use an RPC layer such as tRPC instead. Server Actions remain a good fit for **mutations** (`useMutation`).

If the server latency to the data is low, this might not be a huge issue, but is still worth pointing out.

In Next.js, besides prefetching data in `page.tsx`, you can also do it in `layout.tsx`, and in [parallel routes](https://nextjs.org/docs/app/building-your-application/routing/parallel-routes). Because these are all part of the routing, Next.js knows how to fetch them all in parallel. So if `CommentsServerComponent` above was instead expressed as a parallel route, the waterfall would be flattened automatically.

As more frameworks start supporting Server Components, they might have other routing conventions. Read your framework docs for details.

### Caveat for Next.js rewrites

There's a catch if you're using [Next.js' rewrites feature](https://nextjs.org/docs/app/api-reference/next-config-js/rewrites) together with [Automatic Static Optimization](https://nextjs.org/docs/pages/building-your-application/rendering/automatic-static-optimization) or `getStaticProps`: It will cause a second hydration by React Query. That's because [Next.js needs to ensure that they parse the rewrites](https://nextjs.org/docs/app/api-reference/next-config-js/rewrites#rewrite-parameters) on the client and collect any params after hydration so that they can be provided in `router.query`.

The result is missing referential equality for all the hydration data, which for example triggers wherever your data is used as props of components or in the dependency array of `useEffect`s/`useMemo`s.
