From f8e4be9b36a16969ac53bd9ce12ce8064be10196 Mon Sep 17 00:00:00 2001 From: nsfisis Date: Sun, 4 Jan 2026 17:43:59 +0900 Subject: refactor(client): migrate state management from React Context to Jotai MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace AuthProvider and SyncProvider with Jotai atoms for more granular state management and better performance. This migration: - Creates atoms for auth, sync, decks, cards, noteTypes, and study state - Uses atomFamily for parameterized state (e.g., cards by deckId) - Introduces StoreInitializer component for subscription initialization - Updates all components and pages to use useAtomValue/useSetAtom - Updates all tests to use Jotai Provider with createStore pattern ๐Ÿค– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- src/client/App.test.tsx | 20 +- src/client/atoms/auth.ts | 57 +++ src/client/atoms/cards.ts | 31 ++ src/client/atoms/decks.ts | 37 ++ src/client/atoms/index.ts | 42 ++ src/client/atoms/noteTypes.ts | 22 + src/client/atoms/study.ts | 59 +++ src/client/atoms/sync.ts | 274 ++++++++++++ src/client/atoms/utils.ts | 81 ++++ src/client/components/ErrorBoundary.tsx | 42 ++ src/client/components/LoadingSpinner.tsx | 18 + src/client/components/OfflineBanner.test.tsx | 41 +- src/client/components/OfflineBanner.tsx | 6 +- src/client/components/ProtectedRoute.test.tsx | 49 +- src/client/components/ProtectedRoute.tsx | 8 +- src/client/components/StoreInitializer.tsx | 12 + src/client/components/SyncButton.test.tsx | 153 ++++--- src/client/components/SyncButton.tsx | 7 +- src/client/components/SyncStatusIndicator.test.tsx | 97 ++-- src/client/components/SyncStatusIndicator.tsx | 17 +- src/client/main.tsx | 10 +- src/client/pages/DeckDetailPage.test.tsx | 403 ++++++++--------- src/client/pages/DeckDetailPage.tsx | 494 ++++++++++----------- src/client/pages/HomePage.test.tsx | 452 ++++++------------- src/client/pages/HomePage.tsx | 265 +++++------ src/client/pages/LoginPage.test.tsx | 27 +- src/client/pages/LoginPage.tsx | 9 +- src/client/pages/NoteTypesPage.test.tsx | 243 +++++----- src/client/pages/NoteTypesPage.tsx | 271 +++++------ src/client/pages/StudyPage.test.tsx | 326 ++++++-------- src/client/pages/StudyPage.tsx | 482 +++++++++----------- src/client/stores/auth.test.tsx | 160 ------- src/client/stores/auth.tsx | 92 ---- src/client/stores/index.ts | 15 - src/client/stores/sync.test.tsx | 234 ---------- src/client/stores/sync.tsx | 303 ------------- src/client/test/atomTestUtils.tsx | 20 + 37 files changed, 2165 insertions(+), 2714 deletions(-) create mode 100644 src/client/atoms/auth.ts create mode 100644 src/client/atoms/cards.ts create mode 100644 src/client/atoms/decks.ts create mode 100644 src/client/atoms/index.ts create mode 100644 src/client/atoms/noteTypes.ts create mode 100644 src/client/atoms/study.ts create mode 100644 src/client/atoms/sync.ts create mode 100644 src/client/atoms/utils.ts create mode 100644 src/client/components/ErrorBoundary.tsx create mode 100644 src/client/components/LoadingSpinner.tsx create mode 100644 src/client/components/StoreInitializer.tsx delete mode 100644 src/client/stores/auth.test.tsx delete mode 100644 src/client/stores/auth.tsx delete mode 100644 src/client/stores/index.ts delete mode 100644 src/client/stores/sync.test.tsx delete mode 100644 src/client/stores/sync.tsx create mode 100644 src/client/test/atomTestUtils.tsx (limited to 'src') diff --git a/src/client/App.test.tsx b/src/client/App.test.tsx index 2617f44..189a8e1 100644 --- a/src/client/App.test.tsx +++ b/src/client/App.test.tsx @@ -3,12 +3,12 @@ */ import "fake-indexeddb/auto";
