🎯 Changes

useInfiniteQuery accepts initial data that may be undefined, but Vue's infiniteQueryOptions helper rejected the same optional value or initializer. The fallback overload only allowed undefined, while the defined overload required a guaranteed value.

This type-only fix widens the fallback initialData union with the same value/function forms used by the query APIs and keeps the guaranteed-defined overload first so overload resolution preserves non-undefined data when initial data is guaranteed.

Regression coverage includes six type cases: optional values, optional initializers, select inference, guaranteed values, guaranteed initializers, and absent/explicitly undefined initial data. Generated Vue reference docs and a patch Changeset are included. The follow-up review fix also makes the defined-overload JSDoc precise: it applies when initialData is statically guaranteed to produce defined data, not merely when the property is present.

  • pnpm run generate-docs reproduces the committed generated docs with no diff.
  • Negative control: restoring the original production source makes exactly the 3 optional-initial-data/select regressions fail while 3 control cases pass.
  • Fixed tree: all 6 focused type cases pass.
  • pnpm nx run @tanstack/vue-query:test:types --skip-nx-cache passes for TS 5.6, 5.7, 5.8, 5.9, and 7.0.
  • pnpm nx run @tanstack/vue-query:test:types:tscurrent --skip-nx-cache passes.
  • pnpm nx run @tanstack/vue-query:test:lib --skip-nx-cache passes for Vue 2, 2.7, and 3.
  • pnpm nx run @tanstack/vue-query:test:eslint --skip-nx-cache passes.
  • pnpm nx run @tanstack/vue-query:test:build --skip-nx-cache passes, including publication checks.
  • pnpm run test:pr --base=d346e85f0144eb9b991e6e1665b22f4574de9751 --head=9a1e30d1ead8464b04f5b69e2916485fe4cfdf5f --skip-nx-cache --parallel=2 passes all affected targets and dependency tasks.
  • Prettier, git diff --check, exact-head verification, generated-doc reproduction, changeset presence, and the six-file scope audit pass.

Upstream GitHub Actions for this exact fork head currently stop at the repository authorization gate (action_required) before jobs start; there is no upstream test failure to report.

✅ Checklist

  • I have followed the steps in the Contributing guide.
  • I have tested code changes with pnpm run test:pr on the exact contribution head.
  • I fully understand the code in this pull request, including any code generated with AI assistance. For this 🤖🤖🤖 automated-agent submission, this records agent-side source/test analysis rather than independent human review.

- Line 84: Revise the infiniteQueryOptions overload-selection JSDoc so the
defined overload applies only when initialData is statically guaranteed to
produce defined data, not merely when it is set; update the matching reference
