From 7218285583e3a847c12d08246fecd60b59c8aa5a Mon Sep 17 00:00:00 2001 From: simoleo89 Date: Mon, 11 May 2026 16:31:53 +0000 Subject: [PATCH] Split usePollWidget into subscriptions + actions (proposal #4) + doc update MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit usePollWidget bundled two unrelated responsibilities: - three useNitroEvent listeners that bridge RoomSessionPollEvent (OFFER / ERROR / CONTENT) onto the UI event bus via DispatchUiEvent — pure side-effects, zero local state, should mount once; - three imperative actions (startPoll, rejectPoll, answerPoll) that every consumer wants, but which shouldn't re-register the listeners. In practice the only consumer of usePollWidget was useWordQuizWidget, which needed only `answerPoll` — but pulled in the three subscriptions as a side effect every time the word-quiz widget rendered. That's the classic god-hook anti-pattern this proposal targets. Split (mirrors the doorbell pattern already in place): - src/hooks/rooms/widgets/usePollSubscriptions.ts (new): the three bridge listeners, returns void. Should be mounted ONCE at the highest stable level above poll-aware UI (room widgets root). For now still mounted by the shim — follow-up PR can move it. - src/hooks/rooms/widgets/usePollActions.ts (new): the three imperative actions. Defensive `?.` on roomSession so a poll action during a room transition no longer crashes. - src/hooks/rooms/widgets/usePollWidget.ts: kept as a deprecated shim that composes both — preserves the old `{ startPoll, rejectPoll, answerPoll }` shape so existing consumers don't break. - src/hooks/rooms/widgets/useWordQuizWidget.ts: migrated to import usePollActions directly. The word-quiz widget no longer registers poll subscriptions transitively — its render no longer has the side effect of subscribing to three renderer events. Doc - docs/ARCHITECTURE.md "What's already in place": records both god-hook splits (doorbell + poll), the now-enabled React Query and Zustand, and the test infrastructure. Removes the "not yet enabled" markers for #2 and #5. - "How to pick the next refactor PR": rewritten to reflect that the foundations are done. New priority order: 1. migrate useCatalog's read-only fetches to useNitroQuery, 2. hoist usePollSubscriptions to room-session level, 3. split useCatalog along the doorbell/poll lines, 4. broaden Vitest coverage, 5. per-tab WiredCreatorToolsView split. Verification - yarn eslint on the touched files: 0 errors / 0 warnings. - yarn test: 22/22 passing, 2 files, ~1.0s. - Existing useWordQuizWidget consumers (RoomWidgetsView -> WordQuizWidgetView) unaffected — they import from the barrel which still re-exports the same shape. https://claude.ai/code/session_01GrR87LAqnAEyKG2ZbmQt5Q --- docs/ARCHITECTURE.md | 70 ++++++++++++------- src/hooks/rooms/widgets/index.ts | 2 + src/hooks/rooms/widgets/usePollActions.ts | 19 +++++ .../rooms/widgets/usePollSubscriptions.ts | 47 +++++++++++++ src/hooks/rooms/widgets/usePollWidget.ts | 61 ++++------------ src/hooks/rooms/widgets/useWordQuizWidget.ts | 4 +- 6 files changed, 126 insertions(+), 77 deletions(-) create mode 100644 src/hooks/rooms/widgets/usePollActions.ts create mode 100644 src/hooks/rooms/widgets/usePollSubscriptions.ts diff --git a/docs/ARCHITECTURE.md b/docs/ARCHITECTURE.md index e822c12..bde6d49 100644 --- a/docs/ARCHITECTURE.md +++ b/docs/ARCHITECTURE.md @@ -313,13 +313,21 @@ The current branch (`claude/update-react-typescript-He2rs`) has applied: - **Pattern #1 (`useNitroEventState`)** — implemented + 1 pilot. - **Pattern #3 (feature folder)** — **rejected**; the existing `src/components//` + `src/hooks//` layout is kept. -- **Pattern #4 (split god-hook)** — applied to the doorbell hook: - `src/hooks/rooms/widgets/useDoorbellState.ts` (data) + - `src/hooks/rooms/widgets/useDoorbellActions.ts` (actions). -- **Pattern #2 (`useNitroQuery`)** — adapter prototype written, not yet - enabled (needs `yarn add @tanstack/react-query`). -- **Pattern #5 (Zustand store)** — skeleton written, not yet enabled - (needs `yarn add zustand`). +- **Pattern #4 (split god-hook)** — applied to: + - doorbell: `useDoorbellState` (data) + `useDoorbellActions`; + - poll: `usePollSubscriptions` (3 listeners) + `usePollActions` + (3 imperative actions). `useWordQuizWidget` migrated to import + `usePollActions` directly (it doesn't need the subscriptions). +- **Pattern #2 (`useNitroQuery`)** — **enabled**: `@tanstack/react-query` + installed, `QueryClientProvider` mounted, real adapter in + `src/api/nitro-query/`, first migration on `OfferView`. +- **Pattern #5 (Zustand store)** — **enabled**: `zustand` installed, + `createNitroStore` is now a real re-export, first migration converts + the `let isCreatingRoom` / `createRoomTimeout` singleton in + `NavigatorRoomCreatorView` to `useRoomCreatorStore`. +- **Test infrastructure** — Vitest 3 + jsdom + @testing-library set up. + 22 smoke tests passing on the pure helpers + (`WiredCreatorTools.helpers.ts`) and the new Zustand store. - **Bonus (error boundaries)** — `WidgetErrorBoundary` applied at `RoomWidgetsView`. @@ -327,28 +335,36 @@ The current branch (`claude/update-react-typescript-He2rs`) has applied: ## How to pick the next refactor PR -Order of value/risk for the next contributor: +Foundations #1–#3 (React Query, Zustand, Vitest) are **done**.
