fix(expo): synchronous QueryClient for React Native

[chriscanin]

Summary

• clerk-js lazily loads QueryClient from @tanstack/query-core via rspack's dynamic import('./query-core') code-splitting
• On React Native, Metro bundles everything into a single file — rspack's chunk loading (l.e("675")) never resolves, so clerk.__internal_queryClient stays undefined
• The useClerkQueryClient hook falls back to a no-op mock proxy when undefined, causing useOrganizationList, useSessionList, and other query-based hooks to silently return empty data
• Fix: Object.defineProperty override in createClerkInstance.ts that synchronously creates a QueryClient via require('@tanstack/query-core') on first access, returning the expected { __tag: 'clerk-rq-client', client } shape

Reported by

Donovan (internal) — useOrganizationList returns empty data on React Native

Test plan

• @clerk/expo builds successfully with the change
• TypeScript declarations pass
• Verify useOrganizationList returns data on React Native after fix
• Verify other query-based hooks (useSessionList, etc.) work correctly

Summary by CodeRabbit

• Bug Fixes

  • Query-based hooks (e.g., organization list) on React Native/Expo now reliably load and display results instead of returning empty data.

• Chores

  • Published a patch release for Expo to address the issue and improve runtime behavior on first access.

📝 Walkthrough

Walkthrough

Adds a changeset file for a patch release and modifies the Clerk Expo provider to define a lazy, synchronous getter for the internal TanStack QueryClient (__internal_queryClient) during Clerk instance creation. The getter initializes and returns a QueryClient on first access. No exported or public API declarations were changed.

Code review

Found 1 issue:

1. @tanstack/query-core is not declared as a dependency in packages/expo/package.json. The require('@tanstack/query-core') call at line 122 will fail at runtime if the package isn't resolvable from the @clerk/expo package context. While it is a transitive dependency via @clerk/clerk-js, strict package managers (pnpm) do not hoist transitive dependencies, so this require() will throw Cannot find module '@tanstack/query-core' for consumers. It needs to be added as a dependency or peerDependency in packages/expo/package.json.

	let queryClient: InstanceType<typeof QueryClient> | undefined;

@chriscanin I think it makes sense to add @tanstack/query-core as a peerDependency of @clerk/expo. Otherwise we could expose it as a pass-through in @clerk/clerk-js so it's part of the explicit contract
