Kudzu 0.7.12 lets directly exported same-file row components remain ordinary reusable source while every supported call still specializes to intrinsic DOM.

New in 0.7.12

  • Same-file keyed rows may use direct export function Row declarations.
  • Function-valued export const Row = ... declarations receive the same specialization.
  • One exported row may be reused across multiple keyed maps and ordinary static JSX sites.
  • Every discovered JSX call specializes independently; the exported declaration remains build-only and no component function or name enters browser assets.
  • Existing keyed identity, event handlers, conditions, styles, static callbacks, reorder, and removal behavior remain unchanged.
  • Non-JSX references and dynamic component aliases continue to fail with a source-located may only be referenced as JSX diagnostic.
  • Export-list and default-export aliases, exported state-backed wrappers, and exported reducer-dispatch components remain outside this direct-row fixture.

Benchmark correction (2026-08-02)

The initial cross-framework browser run used external CDP polling, which added protocol latency to short operations. Commit 2ff99a7 replaces those discarded measurements with in-page MutationObserver timing over 31 rotating fresh Chrome profiles.

  • Kudzu: edit 0.5 ms, reverse 4.2 ms, remove 1.3 ms, re-add 1.9 ms.
  • Vue CSR: 0.9 ms, 3.8 ms, 1.3 ms, 0.9 ms.
  • Svelte CSR: 0.8 ms, 20.1 ms, 1.6 ms, 1.3 ms.
  • React CSR: 2.1 ms, 7.5 ms, 2.4 ms, 1.9 ms.
  • Kudzu led edit, tied Vue on remove, and beat React and Svelte on reverse; Vue led reverse and re-add.
  • This correction changes benchmark documentation only. The published 0.7.12 package and runtime are unchanged.

Boundary

This release supports direct export modifiers on same-file keyed row function declarations and function-valued constants. Every local reference must remain a JSX call, and effectful row components may still only run at keyed sites. Imported rows retain their existing default, named, aliased, and direct named re-export support.
