🧹 [code health improvement] Fix build error and add notifications logic

🎯 What

  • Removed an invalid onAction property being passed to the EmptyState component in app/profile/page.tsx which was causing a TypeScript compilation failure during Next.js builds.
  • Refactored the "Notifications" dropdown on the Profile page to be driven by React state rather than static HTML.
  • Implemented "Mark all as read" functionality to successfully clear the notifications array.

💡 Why

  • The invalid onAction prop was breaking the production build.
  • The notifications dropdown was visually appealing but non-functional; connecting it to state makes it interactive and improves the user experience.

Verification

  • Ran npm run build locally to confirm the TypeScript build now succeeds.
  • Verified the notification dropdown visually by writing a Playwright script to click the bell icon, assert the dropdown appears, click "Mark all as read", and assert the notifications clear. All steps succeeded and produced verifying media.

Result

  • The app compiles successfully.
  • Users can now dismiss notifications on their profile page.

Summary by CodeRabbit

  • New Features

    • Added notifications system to the profile page with support for internationalized and custom notification items.

📝 Walkthrough

Walkthrough

The profile page notification system now uses React state to manage notifications, conditionally rendering the badge and dropdown controls based on notification count, supporting both i18n-backed and literal notification entries with per-item styling. A build error from an unsupported prop has been resolved.

Changes

Cohort / File(s) Summary
Notifications State Management
app/profile/page.tsx
Added notifications state array with sample items. Made badge and "mark all read" control conditional on notifications.length > 0. Replaced hardcoded dropdown entries with mapped array rendering supporting i18n translations via isI18n flag and per-notification icon/styling (colorClass, bgClass, opacityClass). Added empty state message. Removed unsupported onAction prop from EmptyState component.
Build Artifact Cleanup
build_output.txt
Deleted TypeScript build error log that reported onAction prop type mismatch in EmptyStateProps.

Estimated code review effort

Poem

🐰 With states that dance and notifications flow,
Badges appear when they have something to show,
I18n whispers and styling takes flight,
Empty states gleam in the digital night,
Build errors vanish—the profile shines bright!

Action required

1. Go Back action missing 🐞
Description
In Profile.renderContent()'s default tab content, EmptyState is given actionLabel but neither
actionHref nor onAction, so the component renders no action button and the “Go Back” CTA disappears.
This affects tabs like “history”, “bookmarks”, and “subscription” which route into the default case.
Code

app/profile/page.tsx[R222-225]

              title={t("profile.coming_soon")}
              description={t("profile.coming_soon_desc")}
              actionLabel={t("profile.go_back")}
-              onAction={() => setActiveTab("overview")}
            />
Evidence
Profile’s default case renders EmptyState with only actionLabel, while EmptyState only renders an
action when actionHref or onAction is provided; therefore no button is shown. The sidebar sets
activeTab to values (history/bookmarks/subscription) that are not handled by switch cases, forcing
those tabs into this default UI with the missing action.

app/profile/page.tsx[217-226]
app/profile/page.tsx[371-410]
components/EmptyState.tsx[38-57]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The Profile page default tab content passes `actionLabel` to `EmptyState` without providing `actionHref` or `onAction`, so `EmptyState` renders no action button and users lose the intended “Go Back” CTA.

## Issue Context
`EmptyState` only renders an action when `actionHref` or `onAction` is present.

## Fix Focus Areas
- app/profile/page.tsx[217-226]

## Suggested fix
Re-add `onAction={() => setActiveTab("overview")}` for the default-case `EmptyState` (or provide an `actionHref`, or remove `actionLabel` if no action is desired).

Remediation recommended

2. Untranslated empty notification text 🐞
Description
When notifications are cleared, the dropdown shows a hardcoded "No new notifications" string instead
of using t(...), making the UI non-localizable and inconsistent with the rest of the dropdown.
This text was introduced with the new state-driven notifications rendering.
Code

app/profile/page.tsx[R294-296]

+                      <div className="py-6 text-center">
+                        <p className="text-sm text-slate-500 dark:text-slate-400">No new notifications</p>
                      </div>
-                      <div>
-                        <p className="text-sm font-medium text-slate-900 dark:text-white">Profile completed</p>
-                        <p className="text-xs text-slate-500 dark:text-slate-400 mt-1">You're all set up.</p>
-                        <p className="text-[10px] text-slate-400 mt-1">1h ago</p>
-                      </div>
-                    </div>
Evidence
The dropdown uses t("profile.notifications_title") and t("profile.mark_all_read"), but the empty
state uses a literal English string. The i18n dictionary includes the other notification-related
keys, confirming this view is intended to be localized.

app/profile/page.tsx[262-297]
lib/i18n.tsx[159-166]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The notifications dropdown renders a hardcoded English message when there are no notifications.

## Issue Context
This component already uses the `t(...)` i18n helper for nearby UI strings.

## Fix Focus Areas
- app/profile/page.tsx[293-296]
- lib/i18n.tsx[159-166]

## Suggested fix
1. Add a new translation key (e.g. `profile.no_notifications`) in `lib/i18n.tsx` for all supported languages.
2. Replace the literal text with `{t("profile.no_notifications")}` in the Profile notifications dropdown empty state.

app/profile/page.tsx (1)

26-29: Consider defining an explicit discriminated union type for notifications.

The current implicit typing creates optional fields for both i18n and literal variants. When combined with non-null assertions at lines 283, 286, 289 (notif.titleKey!), a misconfigured notification (e.g., isI18n: true without titleKey) would cause a runtime error.

🛠️ Suggested type definition
type BaseNotification = {
  id: number
  icon: string
  colorClass: string
  bgClass: string
  opacityClass: string
}

type I18nNotification = BaseNotification & {
  isI18n: true
  titleKey: string
  descKey: string
  timeKey: string
}

type LiteralNotification = BaseNotification & {
  isI18n: false
  title: string
  desc: string
  time: string
}

type Notification = I18nNotification | LiteralNotification

Then use: useState<Notification[]>([...])

This enables TypeScript to enforce that i18n notifications have keys and literal notifications have values.

⚠️ Potential issue | 🟡 Minor

Missing i18n for empty state message.

The text "No new notifications" is hardcoded in English while the rest of the page uses t() for translations. This will display English regardless of the user's language preference.

🌐 Suggested fix
-                        <p className="text-sm text-slate-500 dark:text-slate-400">No new notifications</p>
+                        <p className="text-sm text-slate-500 dark:text-slate-400">{t("profile.no_notifications")}</p>

You'll need to add the corresponding translation key to lib/i18n.tsx.
