Summary

  • preserve row, key, state, page, and custom utility types for React pre-created infinite-query collections
  • model Vue and Svelte conditional callback results with the disabled status and nullable collection their runtimes already return
  • add cross-framework type oracles for each binding disabled representation and Svelte find-one cardinality

Historical contract

PR #886 deliberately established disabled callbacks as collection: null, status: "disabled", and ready empty reactive results across framework bindings. Vue and Svelte did not fully encode that runtime contract. React pre-created infinite-query type erasure dates to PR #684; no compatibility rationale was found. Nullable infinite-query callbacks remain outside this change and tracked by #1729.

Validation

  • TypeScript checks: React, Vue, Solid, Svelte, Angular
  • declaration builds: all five framework packages
  • shared conformance: React 61, Vue 67, Solid 30, Svelte 64, Angular 30 tests
  • React infinite-query suite: 12 tests
  • ESLint, Prettier, and diff hygiene

Runtime JavaScript is unchanged; this PR changes public result types and compile-time coverage only.

Summary by CodeRabbit

  • Bug Fixes
    • Improved TypeScript inference for React infinite queries using pre-created collections, preserving row, key, utility, pagination, and result types.
    • Corrected live-query result types across Angular, React, Solid, Svelte, and Vue when queries are conditionally disabled.
    • Disabled queries now accurately report disabled status, nullable collections, and correctly typed result data.
    • Single-item queries consistently return empty data while disabled and restore results when enabled.
    • Preserved single-item result typing for conditional findOne() queries.

📝 Walkthrough

Walkthrough

The changes update live-query result types across Angular, Solid, Svelte, and Vue. React infinite queries now preserve pre-created collection types. Runtime, type-level, conformance, and release metadata changes cover the updated behavior.

Changes

Live-query result type corrections

Layer / File(s) Summary
React infinite-query collection contract
packages/react-db/src/useLiveInfiniteQuery.ts, packages/react-db/tests/useLiveInfiniteQuery.test-d.tsx
The pre-created collection overload now returns a typed collection result. Tests verify row, key, utility, pagination, state, and collection types.
Conditional live-query return contracts
packages/angular-db/src/index.ts, packages/solid-db/src/useLiveQuery.ts, packages/svelte-db/src/useLiveQuery.svelte.ts, packages/vue-db/src/useLiveQuery.ts
Conditional query overloads add an empty-array type for disabled single-result queries. They preserve nullable collections and disabled statuses where applicable.
Conditional query validation
packages/angular-db/tests/*, packages/solid-db/tests/*, packages/svelte-db/tests/*, packages/vue-db/tests/*, packages/react-db/tests/useLiveQuery.test-d.tsx
Runtime tests verify disabled, enabled, and re-disabled findOne queries. Type tests verify data, collection, status, and invalid preload() access.
Shared contract and release metadata
packages/db/tests/conformance/contract.ts, .changeset/fix-framework-live-query-result-types.md
The conformance contract documents live-query states and observation boundaries. The changeset records patch releases for the affected framework packages.

useLiveQuery and inject-live-query type tests with exact Collection<...> | null
checks at all four identified test sites, asserting both the collection and null
branches. Add the Collection type import in the Angular and Solid tests, and
