fix(react-query): pass the cursor to procedures in createServerSideHelpers infinite helpers - #7721
The infinite helpers on createServerSideHelpers (fetchInfinite, prefetchInfinite, infiniteQueryOptions) call the procedure with the original input for every page, so the cursor never reaches it.
fetchInfinite({}, { initialCursor: 5, pages: 2, getNextPageParam }) returns the cursor-0 page twice with pageParams: [5, 1], and that is what gets dehydrated. The client utils pass cursor and direction from the page context.
infiniteQueryOptions also never set initialPageParam, so initialCursor was dropped there.
What
Build each page's input with getClientArgs, as the client utils do, and use it in all three helpers.
Set initialPageParam from initialCursor in infiniteQueryOptions.
Links
None
Alternatives considered
Building the input from the query key (cursor stripped) would match the client utils exactly, but would break fetchInfinite({ cursor: 5 }), which works today. The cursor check is shared with fix(react-query): always inject cursor field in infinite queries #7361 through getClientArgs.
createHydrationHelpers().prefetchInfinite in rsc.tsx has the same problem. I left it for a follow-up to keep this small.
Testing
New cases in ssg.test.ts (fetchInfinite, prefetchInfinite, infiniteQueryOptions) and ssgExternal.test.ts fail on main and pass here.
@trpc/react-query tests (211), typecheck and lint pass.

Summary by CodeRabbit
Bug Fixes
Infinite queries during server-side rendering now correctly use page cursors and pagination direction when fetching or prefetching.
The initial page parameter is preserved, using the configured cursor or null when none is provided.
Tests
Added coverage for fetching and prefetching multiple pages, including queries with an optional cursor, and for infinite-query options.

Walkthrough
Server-side infinite-query options, fetches, and prefetches now use page-aware request arguments. Tests cover multiple pages, prefetched data, and procedures with and without an initial cursor.

Summary
Build and validate page-aware queries packages/react-query/src/server/ssgProxy.ts, packages/react-query/test/ssg.test.ts, packages/react-query/test/ssgExternal.test.ts
The infinite-query function combines the page parameter or initial cursor with the procedure path, input, and direction. Infinite-query options retain initialPageParam as initialCursor ?? null. Fetches and prefetches use the page-aware function. Tests cover multiple pages, prefetched data, and optional cursors.

…lpers infinite helpers
fetchInfinite, prefetchInfinite and infiniteQueryOptions on the server-side
helpers called the procedure with the original input for every page, so
initialCursor and pages did not change what was fetched. Build the page
input with getClientArgs, as the client utils do, and set initialPageParam
in infiniteQueryOptions.
🤖 Rebased onto main and pushed a fix: since #7361, the helpers sent cursor: null when no initialCursor was given, which broke .optional() cursors with BAD_REQUEST. They now use pageParam ?? initialCursor, as the hooks and utils do.
Added tests with a z.number().optional() cursor for fetchInfinite, prefetchInfinite and infiniteQueryOptions. Your commit is kept as-is. Thanks @NgoQuocViet2001!
Use a scoped server/client resource in both new tests.
Both tests obtain the client from the existing konn fixture. Give each test its own await using ctx = testServerAndClientResource(appRouter) and pass ctx.client to createServerSideHelpers. Extract a router factory if the tests need access to appRouter outside the fixture. The existing helper wraps the resource, but the fixture does not use the required scoped lifetime. (raw.githubusercontent.com)
As per coding guidelines, “ALWAYS use await using ctx = testServerAndClientResource() for tests that need both server and client setup” and “Use the ctx.client directly from the test resource.”

Update both new tests using createServerSideHelpers to create their own scoped

that fixture, extract a router factory so each test can provide it to the
resource.
Make direction forwarding opt-in for standalone SSG helpers.
infiniteQueryFn currently injects direction into every standalone SSG request. A strict cursor-only schema can reject that undeclared field with BAD_REQUEST, so the first fetchInfinite page cannot complete. The same unconditional change is needed by direction-dependent procedures, so omitting the field globally is not safe.
Add a default-off SSG option. Keep the existing client utility behavior unchanged. Enable the option when a standalone SSG procedure requires page direction.
