refactor(app): replace react-helmet-async with React 19 native metadata by google-labs-jules[bot] · Pull Request #12420 · MarkusNeusinger/anyplot

google-labs-jules · 2026-10-28T22:22:24Z

Per-route page metadata uses React 19 native hoisting. Pages render bare <title>, <meta> and <link rel="canonical"> elements instead of wrapping them in react-helmet-async, which is archived upstream; the dependency and its HelmetProvider are gone.

Closes #9629

An active moderate issue remains because the existing filter-state title update overwrites the new /plots route title, and the current test does not exercise the real hook path.

What changed in this PR

This pull request replaces react-helmet-async with React 19 native document metadata across the application, removing the provider and dependency while preserving route-specific titles, descriptions, canonical links, Open Graph tags, robots metadata, and structured data.

Changes:

Replaces Helmet wrappers with native JSX metadata across route pages.
Removes HelmetProvider, the react-helmet-async dependency, and obsolete test mocks.
Updates affected tests, the Yarn lockfile, and changelog.
Two moderate issues remain: static shell metadata can duplicate route metadata, and the /plots title is overwritten by the existing useUrlSync effect.

Closing in favour of #12424, which carries the same migration from the Flash run of this Jules task with every check green and the declarative /plots title fix. This Gemini 3 Pro variant committed four helper scripts (fix_*.cjs, fix_useUrlSync.sh) and rewrote the /plots meta description and canonical link without being asked.

Closing in favour of #12424, which carries the same migration from the Flash run of this Jules task with every check green and the declarative /plots title fix. This Gemini 3 Pro variant committed four helper scripts (fix_*.cjs, fix_useUrlSync.sh) and rewrote the /plots meta description and canonical link without being asked.

Understood. Acknowledging that this work is obsolete and stopping work on this task.

## Summary - In the `jules-task` skill, a losing or duplicate Jules PR is now closed only after its session was told to stop and has settled. Closing a PR wakes its session: on 2026-10-29 the Gemini 3 Pro session of the closed #12420 pushed a new commit and recreated its deleted branch. ## Plan N/A ## Test plan - [x] `uv run python -m tools.changelog check --base origin/main` - [x] Docs-only diff under 20 lines: no Flash check (CLAUDE.md, delegation rule) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

…#12449) ## Summary - `test_local_backend_kills_the_container_on_cancellation` waited at most 10 s for both fake theme containers and then cancelled anyway. On a loaded CI runner that produced a misleading assertion (`['r-cancelme-light'] == ['r-cancelme-dark', 'r-cancelme-light']`, seen once on #12420). The wait is now 25 s (the fake containers live 30 s), and a timeout raises a clear `RuntimeError` instead of falling through. - Written by Google Jules on `feature/deterministic-cancel-test` (#12447). Its description says the root cause was the silent timeout; the race could not be reproduced locally, so this PR claims a clearer and more tolerant test, not a proven fix. `agents/anyplot/render/backends/local.py` is unchanged (the parallel R-pilot session asked for that). ## Plan N/A ## Test plan - [x] `uv run pytest tests/unit/agents/runtime/test_render.py`: passes - [x] `ruff check` - [x] Diff under 20 lines: no Flash pre-PR check (CLAUDE.md delegation rule) --------- Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
