🎯 Changes

The React adapter guide shows how to animate rows as they enter, leave, or move in a live query list. The pattern applies to local writes and incoming sync data.

React handles live query updates synchronously through useSyncExternalStore. The example uses useDeferredValue to give React a background render that can trigger <ViewTransition>. The example uses the stable result key for each row. The guide also shows how to respect reduced motion. A note explains how to guard a Delete button when a deferred list still shows a deleted row.

The React DB skill describes the same pattern. The mutation guide links to the example.

🔬 Oracle Coverage

The changes affect documentation and the packaged skill. They leave runtime behavior unchanged.

✅ Checklist

  • I have tested this code locally with pnpm test.

The example type-checks against React 19.3. Chrome showed animations after an insert, a delete, and a change in sort order. The list also updated with row animations disabled. pnpm lint:changed and git diff --check passed.

🚀 Release Impact

The published React DB package includes the updated skill and a patch changeset.

Summary by CodeRabbit

  • Documentation
    • Added guidance for animating live query updates with React View Transitions, including deferred rendering and reduced-motion preferences.
    • Explained how to use stable, unique keys for animated rows, including when keys contain mixed types.
    • Clarified that deleted rows may remain visible briefly in a deferred view and how to avoid attempting to delete them again.
    • Linked the mutation guide to the React animation guidance.

Walkthrough

Documentation adds a React pattern for animating live-query row updates with <ViewTransition> and useDeferredValue. It covers synchronous store updates, reduced-motion preferences, and checking whether a row still exists before deletion.

Changes: React live-query animation guidance

Layer / File(s) Summary
Document live-query row animation
docs/framework/react/overview.md, packages/react-db/skills/react-db/SKILL.md, docs/guides/mutations.md, .changeset/react-live-query-view-transitions.md
The React guide and skill describe deferring query results, wrapping keyed rows in <ViewTransition>, respecting reduced-motion preferences, and checking the target collection for a record before deleting it. The mutations guide links to the React guide, and a patch changeset records the documentation update.

Explanation

The title names the main change: documentation that shows how to animate live query results with React View Transitions in the react-db adapter. It matches the React guide, the skill, the mutation guide link, and the changeset. The docs(react-db) prefix fits a documentation change. No unrelated content is described.

Full details: Description check

Explanation

The description covers the Changes section with a clear account of the guide, the useDeferredValue pattern, stable keys, reduced-motion handling, and the Delete guard. It also links the skill and mutation guide. The Oracle Coverage section is thin: it says only that documentation changed and runtime behavior is unchanged. It does not name a coverage-map entry or explain why no practical oracle applies, as the template asks for non-bug changes. The checklist item for pnpm test stays unchecked, and the author notes pnpm test was not run, so the Checklist is incomplete. The Release Impact section states a changeset is included but does not tick either box. The description is mostly complete, so the check passes, but the Oracle Coverage gap should be fixed.

Resolution

Consider naming the relevant coverage-map entry in Oracle Coverage and explaining why no practical oracle applies to this docs-only change. Also tick the Release Impact checkbox that matches a published change with a changeset, and state why pnpm test was not run.
