# PR-3 Apply Report: Frontend Core for Notification Center
|
|
|
|
## Status: COMPLETE
|
|
|
|
All 9 tasks for PR-3 (NC-PR3-001 through NC-PR3-009) have been implemented, tested, and validated.
|
|
|
|
## What Was Implemented
|
|
|
|
### NC-PR3-001: Add bell icon to icon registry
|
|
- Added `"bell"` to `IconName` union in `apps/web/src/utils/icons.ts`
|
|
- Added `Bell` import from `@phosphor-icons/react` and mapped it in `iconRegistry`
|
|
- Added `Bell` import and mapping in `apps/web/src/components/icon.tsx`
|
|
|
|
### NC-PR3-002/003: NotificationProvider + useNotifications hook
|
|
- **API client** (`apps/web/src/api/notifications.ts`): Typed wrappers for `GET /notifications`, `GET /notifications/unread`, `PATCH /{id}/read`, `POST /mark-all-read`, `DELETE /{id}`
|
|
- **NotificationProvider** (`apps/web/src/state/notifications.tsx`):
|
|
- Maintains `notifications[]`, `unreadCount`, `isLoading`, `error`, `isDropdownOpen`
|
|
- Polls unread count every 15s, list every 30s (paused when dropdown open)
|
|
- Pauses all polling on `document.hidden`, resumes on visible
|
|
- Stops polling on 401
|
|
- Optimistic updates for `markRead`, `markAllRead`, `dismiss` with revert on failure
|
|
- **useNotifications** (`apps/web/src/hooks/use-notifications.ts`): Thin context consumer hook
|
|
|
|
### NC-PR3-004/005: NotificationCenter + NotificationItem components
|
|
- **NotificationItem** (`apps/web/src/components/notification-item.tsx`):
|
|
- Displays severity icon (mapped from `severity` to existing Phosphor icons)
|
|
- Shows `title` and relative timestamp via `formatRelativeTime`
|
|
- Unread rows: `.notification-item--unread` (accent left border, tinted background, bolder)
|
|
- Read rows: `.notification-item--read` (reduced opacity)
|
|
- "Mark read" and "Dismiss" action buttons with accessible labels
|
|
- **NotificationCenter** (`apps/web/src/components/notification-center.tsx`):
|
|
- Bell icon button with `aria-label="Notifications"`
|
|
- Red badge with unread count, capped at "99+"
|
|
- Dropdown panel with `role="dialog"`, opens on click, closes on outside-click or Escape
|
|
- Scrollable list of `NotificationItem` components
|
|
- Empty state: "No notifications"
|
|
- Footer "Mark all as read" button
|
|
- Calls `refreshList()` immediately on open
|
|
- Hidden when `isMobileTerminal` is true
|
|
|
|
### NC-PR3-006: AppShell integration
|
|
- Wrapped authenticated app layout with `<NotificationProvider>` (inside `EventProvider` + `ToastProvider`)
|
|
- Mounted `<NotificationCenter isMobileTerminal={isMobileTerminal} />` inside `header-actions`, before user chip
|
|
- Mobile terminal shell also wrapped with `NotificationProvider`
|
|
|
|
### NC-PR3-007: CSS styles
|
|
- Added `.notification-center`, `.notification-bell`, `.notification-badge`, `.notification-dropdown`
|
|
- Added `.notification-item`, `.notification-item--unread`, `.notification-item--read`
|
|
- Added `.notification-empty`, `.notification-mark-all`, `.notification-dropdown-header/footer`
|
|
- Responsive: dropdown width adjusts on mobile (`max-width: 360px`)
|
|
- Light/dark theme compatible using existing CSS variables
|
|
|
|
### NC-PR3-008/009: Tests
|
|
- **Hook tests** (`src/hooks/use-notifications.test.tsx`): 9 tests covering state exposure, optimistic updates, revert on failure, refreshList, 401 stop, visibility pause/resume, rapid markRead
|
|
- **NotificationItem tests** (`src/components/notification-item.test.tsx`): 6 tests covering title/time display, unread/read styling, markRead/dismiss callbacks, severity icon
|
|
- **NotificationCenter tests** (`src/components/notification-center.test.tsx`): 10 tests covering bell render, badge show/hide, dropdown open/close (click/outside/escape), empty state, item rendering, markAllRead call, refresh on open

|
## Deviations from Design
|
|
|
|
1. **Polling interval race condition fix:** The dropdown `useEffect` was setting the list poll interval before the initial-start `useEffect` called `startPolling` in React Strict Mode, causing the initial list fetch to be skipped. Fixed by requiring `unreadIntervalRef.current` to be truthy before the dropdown effect resumes list polling, ensuring `startPolling` always owns the initial fetch.
|
|
2. **Relative time formatter:** Added a lightweight custom `formatRelativeTime` utility (`apps/web/src/utils/time.ts`) rather than installing a date library, per the constraint not to add npm packages.
|
|
|
|
## Surprises / Decisions
|
|
|
|
1. **React Strict Mode interval race:** The order of effect execution in Strict Mode caused `listIntervalRef` to be populated before `startPolling` checked it, suppressing the initial list fetch. Adding `&& unreadIntervalRef.current` to the dropdown resume branch fixed this.
|
|
2. **No npm packages installed:** All work used existing dependencies. Custom utility for relative time instead of `date-fns`.
|
|
3. **`toBeInTheDocument` type warnings:** Testing-library jest-dom matchers are not automatically typed in `.test.tsx` files in this project setup. Tests pass at runtime; TypeScript warnings are cosmetic.

|
## PR Boundary
|
|
|
|
This PR covers PR-3 only (NC-PR3-001 through NC-PR3-009). PR-4 (toast coordination — EventToastBridge preferences, settings UI) is out of scope.
