[NotificationCenter] Add NotificationCenter component - #1827
Conversation
📝 WalkthroughWalkthroughChangesThe PR adds a shared notification store, connects the notification handler to it, and introduces an exported Notification center
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The notification center adds persistent history and read controls, but keyboard users cannot mark individual notifications read and its fixed styling may not adapt to active themes. These are bounded UI issues that should be addressed before broad use. Sequence Diagram(s)sequenceDiagram

Adds a persistent, centralized notification surface (bell icon + unread badge + popover history) that aggregates events from the existing notification-handler.ts / notistack pipeline instead of replacing it. Supports read/unread state, per-notification dismiss, and clear-all. Fixes layer5io#399 Signed-off-by: ayanas <ayanasarkar31@gmail.com>

NotificationCenter component so focused users can activate it with both Enter
and Space, marking unread notifications read through markRead(notification.id).
Prefer a native button if compatible; otherwise add an onKeyDown handler while
preserving the existing click behavior.
In `@src/custom/NotificationCenter/style.tsx`:
- Around line 1-2: Update the notification styles in style.tsx to import styled
from the project theme and use theme.palette values within style callbacks.
Replace the fixed WHITE, GRAY, LIGHT_GRAY, and unread blue color values with the
corresponding active Sistent theme tokens, removing the direct theme color
imports while preserving the existing styling structure.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Add keyboard activation for each notification item.
Keyboard users can focus this element but cannot mark an unread notification as read. role="button" and tabIndex={0} do not make a div react to Enter or Space. Use a native button, or handle both keys in onKeyDown.

Use Sistent theme tokens for notification styles.
Use styled from src/theme and read notification colors from theme.palette in the style callbacks. Replace the fixed white, gray, border, and unread blue values so the component adapts to the active Sistent theme.

Adds a persistent, centralized notification surface (bell icon + unread badge + popover history) that aggregates events from the existing
notification-handler.ts/ notistack pipeline instead of replacing it. Previously the only notification-related pieces wereBookmarkNotification(a one-off component) and the generic handler wrapping notistack toasts — nothing let a user review notification history after a toast disappeared.What's new
notificationStore/useNotificationStore(src/custom/Helpers/Notification/notification-store.ts) — a lightweight module-level pub/sub store holding notification history (message, variant, timestamp, read state).useNotificationHandler's existingnotify()now also pushes intonotificationStore, so every current call site gets history for free with no call-site changes.NotificationCenter(src/custom/NotificationCenter/) — bell icon with an unread-count badge; opens a popover listing history with per-item mark-as-read (click) and dismiss, plus header actions for "mark all read" and "clear all".src/custom/index.tsxbarrel export, following the existingBookmarkNotificationpattern.src/__testing__/NotificationCenter.test.tsxcovering badge count, empty state, mark-read, dismiss, and clear-all.Notes for reviewers
notify()now feeds the store automatically rather than requiring an opt-in flag — flagging this since it changes behavior for every existing toast call site with no other code changes. Happy to make it opt-in if that's not the intended design.npm test,npm run lint, andnpx tsc --noEmitall pass locally with no regressions (521 existing tests + 6 new ones).Fixes #399
