🎯 Changes

In @tanstack/solid-query, passing an initialData that can be undefined (e.g. initialData: someCondition ? initialData : undefined) to infiniteQueryOptions was previously rejected by the TypeScript compiler with a type error because UndefinedInitialDataInfiniteOptions did not accept optional/undefined initialData.

This PR:

  • Broadens UndefinedInitialDataInfiniteOptions.initialData to accept optional/undefined initial data, aligning it with queryOptions and other adapters.
  • Adds type-level test coverage in packages/solid-query/src/__tests__/infiniteQueryOptions.test-d.tsx for conditional and possibly-undefined initialData.
  • Includes a patch changeset for @tanstack/solid-query.

✅ Checklist

  • I have followed the steps in the Contributing guide.
  • I have tested code changes locally with pnpm run test:pr, or these tests do not apply to this pull request.
  • I fully understand the code in this pull request, including any code generated with AI assistance.

🚀 Release Impact

  • This change affects published code, and I have generated a changeset.
  • This change is docs/CI/dev-only (no release).

Summary by CodeRabbit

  • Bug Fixes
    • Improved type inference for infinite queries when initialData is provided directly or through a function.
    • Correctly supports initial data that may be undefined while preserving accurate query data types.
    • Improved support for optional initial data in infinite query configuration.
  • Tests
    • Added coverage for conditional and variable-based initialData scenarios.
    • Verified inferred data types across supported initial data patterns.

Fixes TanStack#11286

📝 Walkthrough

Walkthrough

The infinite query options type now accepts defined or function-based initial data. New type-level tests verify undefined-capable data inference for conditional initial data and variables typed as possibly undefined.
