TanStack Query v5 Next.js App Router QueryClient module scope server sharing

💡 Result:

In TanStack Query v5 with the Next.js App Router, using a module-scope QueryClient (a singleton defined at the top level of a module) is strongly discouraged and actively harmful [1]. Because the Next.js server is long-lived, a module-scope client persists across requests, which will lead to data leaking between different users and requests [2][3][1]. The recommended architecture involves two distinct approaches for server and client environments: 1. Server-Side (Per-Request): You must instantiate a fresh QueryClient for every incoming request [3][1]. This is typically implemented using a factory function (e.g., getQueryClient) [4][3][5]. When a Server Component needs to fetch data, it calls this factory to get a request-specific client, performs prefetching, and then passes the dehydrated state to a HydrationBoundary [4][3][5]. 2. Client-Side (Singleton per Session): On the client, you must ensure the QueryClient is instantiated once per browser session [1]. This is usually achieved by creating the client inside a Client Component (typically a provider) using React.useState or a ref, ensuring it is recreated only if the component lifecycle requires it, but stable across the application's life in the browser [2][1]. To implement this pattern: - Define a getQueryClient helper that creates a new QueryClient on the server and retrieves/initializes a singleton on the client [3][5]. - In Server Components, call getQueryClient, perform prefetching with prefetchQuery, and provide the cache to the client-side via a HydrationBoundary [4][3][5]. - Wrap your application in a Client Component provider (e.g., Providers.tsx) that holds the QueryClient instance in state, ensuring the client is stable for the duration of the user's session [2][1]. This approach ensures that the server correctly isolates data for every request while the client maintains a single cache that hydrates seamlessly from the serialized server data [2][3].

site:tanstack.com/query/latest/docs/framework/react Next.js App Router QueryClient useState client provider module scope server request

💡 Result:

In Next.js App Router applications, you must ensure that each server request gets its own QueryClient instance to prevent cross-request data leaking [1][2]. Creating a QueryClient at the module scope (outside of components) is unsafe because it creates a singleton shared across all users and requests [1][2]. To implement this correctly in the App Router: 1. Create a singleton getter function: Define a helper function (e.g., getQueryClient.ts) that uses React's cache function (from react) to ensure the QueryClient instance is memoized for the duration of a single server request. // lib/get-query-client.ts import { QueryClient } from '@tanstack/react-query'; import { cache } from 'react'; const getQueryClient = cache( => new QueryClient); export default getQueryClient; 2. Use a Client Component for the provider: Create a Providers component marked with 'use client' to wrap your application, as QueryClientProvider relies on React Context [3]. // app/providers.tsx 'use client'; import { QueryClientProvider } from '@tanstack/react-query'; import getQueryClient from '@/lib/get-query-client'; export default function Providers({ children }) { const queryClient = getQueryClient; return ( {children} ); } When using the App Router, avoid initializing the client with useState inside the provider component if you are using Server Components for prefetching, as this can lead to issues with React Suspense boundaries [3]. Instead, use the memoized getter function pattern to manage the instance correctly [3]. This ensures that the server creates a fresh client for every request while the client-side remains consistent [3].

site:nextjs.org/docs app router client components prerendered server use client module scope

💡 Result:

In the Next.js App Router, Client Components are indeed prerendered on the server during the initial page load to provide an immediate, non-interactive HTML preview [1][2][3]. This allows users to see the page content before the JavaScript bundle is fully downloaded, parsed, and executed [1][3]. Key aspects of this process include: 1. Server-Side Prerendering: During the initial request, Next.js renders both Server and Client Components into HTML on the server [1][3]. For Client Components, this HTML is a static representation; full interactivity is only enabled once the client-side JavaScript is hydrated [1][3]. 2. The "use client" Module Scope: The "use client" directive marks a boundary between the server and client module graphs [4][5]. When a file is marked with "use client", it and all modules it imports (including child components) are included in the client-side JavaScript bundle [4][1][2]. Because of this, you do not need to repeat the directive in every component; the boundary propagates to all dependencies imported into that module [4][5]. 3. Prerendering and Hooks: When prerendering routes—especially with features like Partial Prerendering (PPR)—navigation hooks that rely on runtime request data (such as useSearchParams, useParams, or usePathname) may not have access to their values [6][7]. If these hooks are called outside of a Suspense boundary, it can cause prerendering errors [6][7]. To resolve this, these components should be wrapped in a Suspense boundary, allowing the server to render a fallback and stream the dynamic component later once the runtime data is available [8][6][7]. 4. Subsequent Navigations: After the initial page load, Client Components are rendered entirely on the client, and the server does not send additional HTML for them [1]. Instead, the React Server Component (RSC) Payload is used to reconcile the component tree and update the DOM [1][3].

TanStack Query v5 useQuery server rendering queryFn executes during Next.js App Router client component prerender no suspense

💡 Result:

In the Next.js App Router, TanStack Query v5's useQuery hook does not execute its queryFn during the server-side prerender or initial server-side rendering (SSR) process [1]. By default, useQuery is designed to execute only on the client side [1]. If a Client Component containing a useQuery hook is prerendered on the server, the queryFn will not run, and the hook will not initiate a data fetch [1]. This behavior persists even if you wrap the component in a Suspense boundary; while Suspense will handle loading states, the actual data fetching triggered by useQuery will only begin once the component mounts in the browser [1]. To achieve server-side rendering and avoid a "loading" state during initial page load, you must use the standard hydration pattern [2][3][4]: 1. Prefetching: Use queryClient.prefetchQuery within a Server Component to fetch the data on the server [2][3]. 2. Dehydration: Wrap your client components in a HydrationBoundary component and pass the dehydrated state from your queryClient [2][5][6]. 3. Rehydration: On the client, when the page loads, useQuery will detect the prefetched data in the cache and provide it immediately, bypassing the need for a client-side fetch [3][4][6]. If you omit the prefetch step, your client-side useQuery hook will simply remain idle during the server render and will trigger the fetch only after the component reaches the client [1]. Note: If you use the newer useSuspenseQuery hook in a Client Component, it is still subject to the same requirement—it will not trigger server-side fetching unless that data has been explicitly prefetched on the server and passed down via HydrationBoundary [2][7]. Without prefetching, useSuspenseQuery will simply suspend the component on the client after the initial HTML has been rendered [1][8]. Additionally, be aware that calling dehydrate during certain prerendering phases (such as with Cache Components in newer Next.js versions) can sometimes trigger errors related to reading the current time if not handled correctly; ensure you are following the latest official TanStack Query documentation for hydration patterns [9].

site:tanstack.com/query/v5/docs/framework/react/guides/advanced-ssr useQuery Server Components queryFn server

💡 Result:

In TanStack Query, you cannot use the useQuery hook directly within React Server Components because hooks are only supported in Client Components [1]. Instead, to leverage TanStack Query with Server Components, you should perform the following pattern: 1. Prefetching on the Server: In your Server Component, create a QueryClient, use await queryClient.prefetchQuery to fetch your data, and then dehydrate the state [1]. 2. Hydration: Wrap your component tree in a HydrationBoundary (a Client Component) and pass the dehydrated state to it [1]. 3. Client-Side Access: In your Client Components (children of the HydrationBoundary), use the standard useQuery hook. Because the data has already been prefetched and dehydrated, useQuery will immediately use that cached data without triggering a redundant network request [1]. Regarding queryFn and Server Actions: Do not use Server Actions as the queryFn for fetching data in useQuery [1]. Server Actions run serially when called from the client, which can cause performance bottlenecks or issues with React Query's parallel fetching and refetching logic [1]. Additionally, passing Server Actions as references can lead to serialization errors [1]. Server Actions should be used for mutations (via useMutation), while data fetching should rely on standard fetch requests, API routes, or RPC libraries [1].

Use the root QueryClientProvider instead of creating a page-level client. The root Providers component already owns a state-stable QueryClient. The page-level provider creates a separate cache and bypasses the root query defaults. These page queries do not prefetch or execute on the server, so this is not a cross-request data-leak issue.

🚀 Performance & Scalability | 🟠 Major | ⚡ Quick win

The search input triggers one request per keystroke.

Line 70 passes search directly into useMarketplace. Line 170 updates search on every onChange. Each character therefore produces a new query key and a new fetch. Typing a 20-character originator address issues 20 requests, and the responses can resolve out of order.

Debounce the value that feeds the query, and keep the raw value for the input.

🐛 Proposed fix 
-  const allInvoicesQuery = useMarketplace({
-    currency: filters.currency !== 'ALL' ? filters.currency : undefined,
-    search: search || undefined,
-  });
+  // Debounce the search term so typing does not issue one request per keystroke.
+  const [debouncedSearch, setDebouncedSearch] = useState('');
+
+  useEffect(() => {
+    const timer = setTimeout(() => setDebouncedSearch(search), 300);
+    return () => clearTimeout(timer);
+  }, [search]);
+
+  const allInvoicesQuery = useMarketplace({
+    currency: filters.currency !== 'ALL' ? filters.currency : undefined,
+    search: debouncedSearch || undefined,
+  });

Add useEffect to the React import on line 3.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Compare amounts as bigint in the sort comparator.

Invoice.amount is a bigint of stroops. Lines 84 and 85 convert both operands with Number. Above 2^53 stroops the conversion rounds, two distinct amounts can map to the same double, and the comparator then reports a tie. Compare the bigint values and return a fixed sign.

🐛 Proposed fix 
-        case 'amount_desc': return Number(b.amount) - Number(a.amount);
-        case 'amount_asc':  return Number(a.amount) - Number(b.amount);
+        case 'amount_desc': return a.amount === b.amount ? 0 : (a.amount < b.amount ? 1 : -1);
+        case 'amount_asc':  return a.amount === b.amount ? 0 : (a.amount < b.amount ? -1 : 1);

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Add accessible names to the status and currency selects.

The sort select on line 192 declares aria-label="Sort invoices". The status select on line 173 and the currency select on line 183 declare no label element and no aria-label. A screen reader announces only the current value, so the user cannot tell which filter the control changes.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

A failed query renders as "No invoices match your filters".

The browse-all view branches on allInvoicesQuery.isLoading only. If the query fails, isLoading is false and sortedAll is empty, so line 210 shows the empty-filter message. The user reads a fetch failure as a valid empty result and has no retry path. The suggested view already receives isError on line 153, so the two views report failures inconsistently.

Handle the error state before the empty state.

Apply the same !allInvoicesQuery.isError guard to the grid block on line 217.

Update the browse-all rendering around allInvoicesQuery and sortedAll so the
empty-filter message is suppressed when allInvoicesQuery.isError is true, and
handle the failed-query state before the empty state with the existing
error/retry behavior used by the suggested view. Ensure the invoice grid is also
guarded against rendering during an error.
