# 4.2 API Integration Points

Primary API Call (from story-2.4 spec):

GET /api/v1/events?filter={"status":"published"}&sort=-eventDate&limit=1&include=venue,speakers,sessions,topics,agenda

Data Mapping:

Action Items:

1. Replace all hardcoded event data with API responses
2. Implement speaker cards with real data (photos from S3)
3. Add loading states with skeleton screens
4. Implement error handling for API failures
5. Add data refresh mechanism (e.g., every 5 minutes for registration count)

# 4.3 State Management

// Suggested state structure using React Query + Zustand

// React Query for server state
const { data: currentEvent, isLoading, error } = useQuery({
  queryKey: ['currentEvent'],
  queryFn: fetchCurrentPublishedEvent,
  refetchInterval: 5 * 60 * 1000, // 5 minutes for live registration count
});

// Zustand for UI state
interface UIState {
  mobileMenuOpen: boolean;
  setMobileMenuOpen: (open: boolean) => void;
}

# 4.4 Responsive Breakpoints

// Tailwind breakpoints used in design
const breakpoints = {
  sm: '640px',   // Mobile landscape
  md: '768px',   // Tablet
  lg: '1024px',  // Desktop
  xl: '1280px',  // Large desktop
};

// Key responsive changes:
// - Navigation: hamburger menu < md, full nav >= md
// - Hero grid: 1 column < md, 2 columns >= md
// - Typography: scales down 20% on mobile
// - Gallery: 4 cols mobile, 12 cols desktop (asymmetric layout)
// - Past events: 1 col mobile, 3 cols desktop

# 4.5 Performance Optimizations

Image Loading:

• Lazy load gallery images with Intersection Observer
• Use WebP format with JPEG fallbacks
• Implement progressive image loading (LQIP blur-up)
• CDN delivery via CloudFront

Code Splitting:

// Lazy load photo gallery component (not critical above fold)
const PhotoGallery = React.lazy(() => import('./Gallery/PhotoGallery'));

// Wrap in Suspense with loading fallback
<Suspense fallback={<GallerySkeleton />}>
  <PhotoGallery />
</Suspense>

Bundle Size:

• Current design uses lucide-react icons (tree-shakeable, small bundle)
• Tailwind CSS with PurgeCSS removes unused styles
• Estimated bundle size: <50KB gzipped (excellent)

# 5. Design System Integration

# 5.1 New Color Palette (Dark Theme)

Add to front-end-spec.md Section 6.2:

# 5.2 New Components for Component Library

Add to front-end-spec.md Section 5.2:

# 5.2.9 Asymmetric Photo Gallery Component (NEW)

Purpose: Modern masonry-style photo gallery with asymmetric grid layout and hover effects

Variants:

• Masonry Grid (Default) - 12-column grid with variable row spans
• Placeholder Mode (Initial state) - Gradient placeholders with icon indicators
• Loaded Mode (With images) - Full photos with overlay effects

States:

• loading - Skeleton loading animation
• placeholder - Gradient boxes with icons (as shown in new design)
• loaded - Real event photos with hover overlay
• error - Error state with retry option

Layout Structure (12-column grid):

┌────────────────┬─────────┐
│                │         │
│   Large 7×2    │ Med 5×1 │
│                │         │
├────┬─────┬─────┴───┬─────┤
│3×1 │ 2×1 │  Wide   │     │
│    │     │   7×1   │     │
├────┴─────┴─────────┤ 5×2 │
│                    │     │
│     (repeat)       │     │
└────────────────────┴─────┘

Usage Guidelines:

• Use for event photo showcases (past events, venue photos)
• Minimum 6 photos for balanced layout
• Maximum 12 photos per gallery (pagination for more)
• Images should be high quality (min 1200px width)
• Maintain 16:9 or 4:3 aspect ratios
• Add alt text describing photo content
• Hover effects: Blue overlay (blue-400/10 opacity) + scale(1.02)

Accessibility:

• Each image has descriptive aria-label
• Keyboard navigable with tabIndex={0} on each item
• Focus indicators visible (ring-2 ring-blue-400)
• Semantic role="list" and role="listitem"

React Implementation Notes:

• Built with Tailwind CSS Grid
• Responsive: 4-column mobile, 12-column desktop
• auto-rows-[200px] for consistent row height
• CSS Grid col-span-* and row-span-* for asymmetry
• Lazy loading with Intersection Observer
• CDN images with WebP format

# 6. Migration Strategy & Rollout Plan

# Phase 1: Development (Week 1-2)

Sprint 1.1: Core Component Setup

1. Create React component structure (see Section 4.1)
2. Set up Tailwind CSS with custom zinc/blue palette
3. Implement navigation (desktop + mobile hamburger)
4. Build hero section with event metadata

Sprint 1.2: API Integration

1. Integrate consolidated API call (from story-2.4 spec)
2. Replace hardcoded data with API responses
3. Add loading states (skeleton screens)
4. Implement error handling

Sprint 1.3: Additional Sections

1. Build photo gallery component (with placeholders)
2. Implement about section
3. Create past events grid
4. Build newsletter signup form

# Phase 2: Testing & Refinement (Week 3)

Testing Checklist:

• Accessibility audit with axe-core (automated)
• Manual keyboard navigation testing (all interactive elements)
• Screen reader testing (NVDA, JAWS, VoiceOver)
• Color contrast verification (all combinations)
• Mobile responsiveness testing (320px - 1920px)
• Cross-browser testing (Chrome, Firefox, Safari, Edge)
• Performance testing (Lighthouse score > 90)
• API integration testing (mock data + real data)

Refinement:

• Address any accessibility issues found
• Optimize performance (lazy loading, code splitting)
• Fine-tune responsive breakpoints
• Polish animations and transitions

# Phase 3: Stakeholder Review (Week 4)

Review Sessions:

1. Design Review: Present to stakeholders (organizers, partners)
2. User Testing: 5-10 potential attendees test prototype
3. Feedback Collection: Document requested changes
4. Iteration: Implement high-priority feedback

Key Questions for Stakeholders:

• Does the dark theme align with BATbern brand identity?
• Is the event information clear and scannable?
• Is the registration CTA prominent enough?
• Do the past events and about sections provide value?
• Is the German language content appropriate?

# Phase 4: Deployment (Week 5)

Deployment Strategy:

1. Staging Deployment: Deploy to staging environment
2. A/B Testing (Optional): 50/50 split between old and new design
3. Analytics Setup: Track engagement metrics
4. Soft Launch: Deploy to production with monitoring
5. Full Launch: Switch all traffic to new design

Success Metrics:

• Registration conversion rate > current baseline
• Bounce rate < current baseline
• Time on page > current baseline
• Mobile traffic engagement improved
• Accessibility audit score: 100% WCAG 2.1 AA

# 7. Open Questions & Recommendations

# 7.1 Open Questions

1. Free Admission Badge: Original spec has explicit “FREE ADMISSION” badge. Should we add this to the new design?

   • Recommendation: Add “FREE” badge next to registration CTA for clarity

2. Speaker Data: Current design has placeholder icons. When will real speaker data be available?

   • Recommendation: Priority HIGH - Implement speaker cards with photos from API

3. Photo Gallery Content: Gallery uses placeholder gradients. Do you have event photos ready?

   • Recommendation: Start with placeholders, replace progressively as photos become available

4. Language Switcher: Original spec has EN/DE switcher. Should this be in the nav?

   • Recommendation: Add language switcher to top-right of navigation

5. Event Type Flexibility: Original spec shows full-day event (8:30-17:30), new design shows evening event (18:00-21:00). Which is correct?

   • Recommendation: Make flexible - support both full-day and evening events via API

6. Dark Theme Brand Alignment: Does the dark theme align with BATbern’s existing brand?

   • Recommendation: If uncertain, consider theme toggle (light/dark mode) for user choice
