perf(render): migrate Sidebar to the selector store - #426
Conversation
Sidebar reads five whole-domain hooks (useStudents, useGrading, useAuthoring, useAssessment, useSettings) to build the moderation badge and admin link. It now selects the five slices it renders via a single useStoreSelector, so the component re-renders only when students, studentRubrics, rubrics, peerReviews, or settings actually change — not on any unrelated collection update. 🤖 Generated with Codebuff Co-Authored-By: Codebuff <noreply@codebuff.com>

Estimated code review effort: 2 (Simple) | ~10 minutes Mergeability Score: 🔵 Low · up to The Sidebar migration is mergeable with owner awareness, but selecting the full settings object can still trigger unnecessary rerenders when unrelated settings change, leaving the performance isolation slightly incomplete; the test mock also weakens compile-time validation without affecting runtime behavior.

📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win
Keep the selector mock type-safe.
(state: any) => any removes compile-time checking for the store state and selector result. Use the repository's exported store-state type and a generic return type so the mock cannot drift from the useStoreSelector contract.
As per coding guidelines, strict mode is on, and existing domain shapes must use central type definitions instead of ad-hoc inline types.

🚀 Performance & Scalability | 🟡 Minor | ⚡ Quick win
Select the scalar setting used by the sidebar.
Sidebar reads only settings.userRole. When an unrelated settings update replaces the settings object, useStoreSelector sees a new top-level reference and re-renders Sidebar although isAdmin is unchanged. Select s.settings.userRole as userRole instead.
Proposed selector refinement
- const { students, studentRubrics, rubrics, peerReviews, settings } = useStoreSelector((s) => ({
+ const { students, studentRubrics, rubrics, peerReviews, userRole } = useStoreSelector((s) => ({
students: s.students,
studentRubrics: s.studentRubrics,
rubrics: s.rubrics,
peerReviews: s.peerReviews,
- settings: s.settings,
+ userRole: s.settings.userRole,
}));
- const isAdmin = settings.userRole === 'admin';
+ const isAdmin = userRole === 'admin';📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

…on stacked PRs The roster domain hooks filtered soft-deleted rows (archived students, deleted student rubrics); the selector-store migration read raw slices, so archived students could inflate moderation badges. Restore the filter with useMemo, select userRole directly, and type the test mock against StoreData. Also stop filtering CI's pull_request trigger to main so stacked PRs (base = another PR's head) actually run checks. 🤖 Generated with Codebuff Co-Authored-By: Codebuff <noreply@codebuff.com>

What
Migrates
Sidebarfrom five whole-domain hooks (useStudents,useGrading,useAuthoring,useAssessment,useSettings) to a singleuseStoreSelectorthat reads exactly the five slices it renders.Why
The sidebar renders a global moderation badge and admin link, so it must re-render whenever any of those collections change — but subscribing to the whole domains re-renders it on every unrelated collection update too. Selecting only
students,studentRubrics,rubrics,peerReviews,settingsisolates it to the data it actually displays.Notes
Sidebar.test.tsxnow routesuseStoreSelectorthrough its mocked app value;pages.a11y.test.tsxalready covered the selector store.Part of the roadmap "Up Next" selector-store migration series (stacked).
