Key Interactive Elements

  • Logo Button: Click to navigate to role-specific dashboard (home screen for current role)
  • Main Menu Items: Horizontal tabs that navigate to role-specific portal sections (highlighted on current section)
  • Notification Bell (πŸ””): Click to open notification dropdown with unread count badge (manual reload to update)
  • Reload Button (↻): Manual reload button in notification dropdown to fetch latest notifications
  • User Avatar Dropdown (@β–Ό): Click to open user menu with profile, settings, help, language switcher, logout
  • Help Icon (?): Quick access to context-sensitive help and documentation
  • Language Switcher: Dropdown in user menu to toggle between German (Deutsch) and English
  • Hamburger Menu (☰): Mobile-only responsive navigation toggle (appears on screens < 768px)
  • Breadcrumb Trail: Contextual navigation showing current location in app hierarchy (clickable links)
  • Role Badge: Visual indicator showing current user role (changes color per role: Organizer=blue, Speaker=green, Partner=purple, Attendee=orange)

Functional Requirements Met

  • FR1 (Multi-Role User Management): Navigation adapts dynamically based on authenticated user’s role from JWT token
  • Story 1.17 (React Frontend Foundation): Implements role-adaptive component architecture with shared navigation component
  • Story 1.20 (User Role Management): Displays current role and provides access to profile/settings for role management
  • Story 1.2 (Authentication): Integrates AWS Cognito authentication state and provides logout functionality
  • Frontend Architecture (05-frontend-architecture.md): Implements BaseLayout and NavigationItem component patterns with role-based menu configuration

Technical Notes

Component Architecture

  • Component: <AppHeader> (React functional component with TypeScript)
  • State Management:
    • Zustand store for UI state (sidebar open, notifications)
    • React Query for user profile and notification data
    • Auth context from Cognito (user, role, permissions)
  • Navigation Config: Static configuration in frontend code: navigationConfig: Record<UserRole, NavigationItem[]> (see frontend architecture)
  • Responsive Design: Mobile-first with breakpoints at 768px (tablet) and 1024px (desktop)
  • Notification Updates: Manual reload only (no WebSocket or polling)

Material-UI Components

  • AppBar with position="fixed" and elevation={1}
  • Toolbar for horizontal layout
  • IconButton for notification bell and user avatar
  • Menu and MenuItem for dropdowns
  • Badge for notification count
  • Drawer for mobile hamburger menu
  • Breadcrumbs component for navigation trail
typescript
interface NavigationItem {
  id: string;
  label: string;
  icon: React.ComponentType;
  path: string;
  roles: UserRole[];
  children?: NavigationItem[]; // For nested menus
}

Search Functionality

  • Not included in MVP - Deferred to Epic 5 (Attendee Experience - Content Discovery)
  • Search functionality will be implemented per-screen where needed (e.g., speaker search in Speaker Matching Interface)

Accessibility

  • Semantic HTML5 <nav> element with proper ARIA labels
  • Keyboard navigation with Tab/Shift+Tab (focus trap in dropdown menus)
  • Screen reader announcements for notification updates
  • Focus indicators meet WCAG 2.1 AA contrast requirements (3:1 minimum)
  • Skip to main content link for screen readers

Internationalization (i18n)

Per frontend architecture requirements (docs/architecture/05-frontend-architecture.md):

Supported Languages:

  • Primary: German (de-CH) - Swiss German locale (default/fallback)
  • Secondary: English (en-US)

Implementation:

  • Library: react-i18next with i18next-browser-languagedetector
  • Translation Namespaces: Navigation uses common namespace for menu items, buttons, labels
  • Language Detection Priority:
    1. User Profile (from /api/v1/users/me β†’ preferredLanguage field)
    2. LocalStorage (batbern-language key)
    3. Browser Language (navigator.language)
    4. Default Fallback: German (de)

Translated Elements:

  • Menu item labels (Events, Topics, Speakers, etc.)
  • User menu items (Profile & Settings, Notifications, Help Center, Logout)
  • Notification dropdown text (β€œNotifications”, β€œMark all as read”, β€œView All Notifications”)
  • Button labels (Reload, View, etc.)
  • Role labels (β€œRole: Organizer” β†’ β€œRolle: Organisator”)
  • Error messages and loading states

Language Switcher Behavior:

  1. User clicks language dropdown in user menu
  2. Selects new language (Deutsch/English)
  3. API call to PUT /api/v1/users/me/language persists preference
  4. i18next.changeLanguage(newLang) updates UI immediately
  5. document.documentElement.lang attribute updated for accessibility
  6. LocalStorage updated as backup
  7. All navigation text re-renders with new translations
  8. ARIA announcement: β€œLanguage changed to {language}” (screen reader)

Date/Time Formatting:

  • Notification timestamps use date-fns with locale support
  • German: β€œvor 2 Stunden” (2 hours ago)
  • English: β€œ2 hours ago”

Accessibility:

  • <html lang="de"> or <html lang="en"> attribute updated on change
  • Screen reader announcement via aria-live="polite" region
  • Language switcher has aria-label="Change language" in current language

Performance Optimization

  • Lazy loading for dropdown menu components
  • React.memo for navigation items to prevent unnecessary re-renders
  • Simple pagination for notifications (load 10 at a time with β€œLoad More” button)
  • i18n namespaces: Load common namespace immediately, lazy-load role-specific namespaces on first use

API Requirements

Initial Page Load APIs

  1. GET /api/v1/users/me?include=roles,preferences (Story 1.23)

    • Consolidation: Uses ?include= pattern to fetch user profile, roles, and preferences in a single request
    • Triggered on: App initialization after authentication
    • Query params:
      • include=roles,preferences (expanded data in single request)
    • Returns:
      json
      {
        "userId": "uuid",
        "email": "john.doe@example.com",
        "firstName": "John",
        "lastName": "Doe",
        "currentRole": "ORGANIZER",
        "availableRoles": ["ORGANIZER", "SPEAKER"],
        "companyId": "uuid",
        "profilePhotoUrl": "https://cdn.example.com/...",
        "preferences": {
          "language": "de",
          "notifications": { ... },
          "theme": "light"
        }
      }
      
    • Used for: Populating user profile in navigation bar, determining role-based menu items, language settings
    • Cache: React Query cache for 5 minutes, invalidate on user profile update
    • Performance: <100ms (P95) with caching
    • Consolidation Benefit: Replaces 3 separate calls (user profile, roles, preferences)
  2. GET /api/v1/notifications?status=unread&limit=10 (Story 1.26)

    • Consolidation: Simplified query with ?status= filter instead of separate endpoint
    • Triggered on: App initialization, manual reload in notification dropdown
    • Query params:
      • status=unread (filter for unread notifications)
      • limit=10 (show 10 notifications per page in dropdown)
    • Returns:
      json
      {
        "notifications": [
          {
            "id": "uuid",
            "type": "EVENT_STATUS_CHANGED",
            "title": "Event status changed",
            "message": "Event 'BATbern 2025' is now Published",
            "timestamp": "2024-03-15T14:30:00Z",
            "isRead": false,
            "actionUrl": "/events/uuid",
            "priority": "NORMAL"
          }
        ],
        "unreadCount": 3,
        "totalCount": 47,
        "hasMore": true
      }
      
    • Used for: Notification bell badge count, notification dropdown list
    • Cache: React Query with 5-minute stale time, manual refresh only
    • Performance: <200ms (P95)
    • Consolidation Benefit: Single endpoint replaces 11 notification-related endpoints
  3. Navigation Menu Items

    • Static configuration in frontend (no API call)
    • Menu items defined in TypeScript config file: src/config/navigationConfig.ts
    • Role-based rendering using current user’s role from JWT token
    • Example structure:
      typescript
      const navigationConfig: Record<UserRole, NavigationItem[]> = {
        ORGANIZER: [
          { id: 'events', label: 'Events', path: '/organizer/events', icon: EventIcon },
          { id: 'topics', label: 'Topics', path: '/organizer/topics', icon: TopicIcon },
          { id: 'speakers', label: 'Speakers', path: '/organizer/speakers', icon: SpeakerIcon }
        ],
        // ... other roles
      };
      
    • No API call needed, instant rendering based on auth state

User Action APIs

  1. PUT /api/v1/notifications/read (Story 1.26)

    • Consolidation: Unified endpoint supports both single and bulk read operations
    • Triggered by: User clicks notification item or β€œMark as read” button or β€œMark all as read”
    • Payload (single):
      json

Responsive Design Considerations

Mobile Layout Changes (< 768px)

  • Hamburger Menu: Replace horizontal menu items with hamburger icon (☰)
    • Opens full-screen overlay menu with vertical navigation list
    • Slide-in animation from left (300ms transition)
    • Close with hamburger icon, overlay click, or swipe-right gesture
  • Notification/User Icons: Remain visible in top-right
  • Logo: Shrink to icon-only version (square logo) on very small screens (< 480px)
  • Breadcrumbs: Hide on mobile (< 768px), rely on hamburger menu and page title

Tablet Layout Changes (768px - 1024px)

  • Menu Items: Full horizontal menu with abbreviated labels if needed
  • Notification Dropdown: Full-width dropdown instead of fixed width
  • User Menu: Shift to left edge of dropdown to avoid viewport overflow

Mobile-Specific Interactions

  • Swipe Right on Hamburger Menu: Close mobile navigation menu
  • Tap Outside Dropdown: Close dropdown menu (notification or user menu)
  • Long Press on Menu Item: Show tooltip or submenu (if nested navigation)
  • Pull-to-Refresh: Refresh current page data (optional, native browser behavior)

Accessibility Notes

  • Semantic HTML: <nav> element with aria-label="Main navigation" for primary navigation
  • Keyboard Navigation:
    • Tab key moves focus through: Logo β†’ Search β†’ Menu Items β†’ Notification β†’ User Avatar β†’ Help
    • Arrow keys navigate within dropdown menus
    • Enter/Space activates focused item
    • Escape closes open dropdowns
    • Shift+Tab reverses focus direction
  • Screen Reader Support:
    • aria-label on all icon-only buttons (notification bell, user avatar, help)
    • aria-live="polite" region for notification count updates
    • aria-expanded attribute on dropdowns (true/false)
    • aria-current="page" on active menu item
    • role="menu" and role="menuitem" for dropdown menus
  • Focus Indicators:
    • Visible focus outline on all interactive elements (2px solid blue)
    • Minimum 3:1 contrast ratio against background (WCAG 2.1 AA)
    • Focus trap in open dropdown menus (Tab cycles within menu)
  • Color Contrast:
    • Text meets WCAG 2.1 AA standard (4.5:1 for normal text, 3:1 for large text)
    • Role badges use distinct colors with sufficient contrast
    • Notification badge uses red with white text (high contrast)
  • ARIA Announcements:
    • New notifications announced via aria-live="assertive" (if critical) or "polite" (if informational)
    • Role change announced: β€œYour role has been updated to Speaker”
    • Logout announced: β€œYou have been logged out”
