Dev Notes - Implementation Guide

Unit Testing Example

EventHero.test.tsx:

typescript

import { render, screen } from '@testing-library/react';
import { BrowserRouter } from 'react-router-dom';
import { EventHero } from '@/components/public/Event/EventHero';

const mockEvent = {
  id: 'BATbern025',
  title: 'Cloud-Native Architecture',
  description: 'An evening of architecture discussions',
};

describe('EventHero', () => {
  it('should render event title', () => {
    render(
      <BrowserRouter>
        <EventHero event={mockEvent} />
      </BrowserRouter>
    );
    expect(screen.getByText('Cloud-Native Architecture')).toBeInTheDocument();
  });

  it('should render register button', () => {
    render(
      <BrowserRouter>
        <EventHero event={mockEvent} />
      </BrowserRouter>
    );
    expect(screen.getByText('Register Now')).toBeInTheDocument();
  });

  it('should link to registration page', () => {
    render(
      <BrowserRouter>
        <EventHero event={mockEvent} />
      </BrowserRouter>
    );
    const link = screen.getByText('Register Now').closest('a');
    expect(link).toHaveAttribute('href', '/register/BATbern025');
  });
});

E2E Testing Example

e2e/registration-flow.spec.ts:

typescript

import { test, expect } from '@playwright/test';

test.describe('Event Registration Flow', () => {
  test('should complete full registration', async ({ page }) => {
    // 1. Browse event
    await page.goto('http://localhost:3000/current-event');
    await expect(page.getByText('Cloud-Native Architecture')).toBeVisible();

    // 2. Click register
    await page.click('text=Register Now');
    await expect(page).toHaveURL(/\/register\//);

    // 3. Fill personal info (Step 1)
    await page.fill('input[name="firstName"]', 'John');
    await page.fill('input[name="lastName"]', 'Doe');
    await page.fill('input[name="email"]', 'john@example.com');
    await page.fill('input[name="company"]', 'Acme Corp');
    await page.fill('input[name="role"]', 'Architect');
    await page.click('text=Next');

    // 4. Select sessions (Step 2)
    await page.click('[data-testid="session-checkbox"]:first-child');
    await page.click('text=Next');

    // 5. Review and accept terms (Step 3)
    await page.click('[data-testid="terms-checkbox"]');
    await page.click('text=Complete Registration');

    // 6. Verify confirmation page
    await expect(page).toHaveURL(/\/registration-confirmation\//);
    await expect(page.getByText('Registration Confirmed!')).toBeVisible();

    // 7. Verify QR code exists
    await expect(page.locator('img[alt*="QR Code"]')).toBeVisible();
  });

  test('should show validation errors', async ({ page }) => {
    await page.goto('http://localhost:3000/register/BATbern025');
    await page.click('text=Next'); // Try to proceed without filling form
    await expect(page.getByText('First name is required')).toBeVisible();
  });
});

SEO Meta Tags

MetaTags.tsx:

typescript

import { Helmet } from 'react-helmet-async';

interface MetaTagsProps {
  title: string;
  description: string;
  image?: string;
  url?: string;
  type?: 'website' | 'article';
}

export const MetaTags = ({ title, description, image, url, type = 'website' }: MetaTagsProps) => {
  const fullTitle = `${title} | BATbern`;
  const defaultImage = 'https://batbern.ch/og-image.jpg';
  const defaultUrl = 'https://batbern.ch';

  return (
    <Helmet>
      {/* Basic Meta */}
      <title>{fullTitle}</title>
      <meta name="description" content={description} />
      <link rel="canonical" href={url || defaultUrl} />

      {/* Open Graph */}
      <meta property="og:type" content={type} />
      <meta property="og:title" content={fullTitle} />
      <meta property="og:description" content={description} />
      <meta property="og:image" content={image || defaultImage} />
      <meta property="og:url" content={url || defaultUrl} />
      <meta property="og:site_name" content="BATbern" />

      {/* Twitter Card */}
      <meta name="twitter:card" content="summary_large_image" />
      <meta name="twitter:title" content={fullTitle} />
      <meta name="twitter:description" content={description} />
      <meta name="twitter:image" content={image || defaultImage} />
    </Helmet>
  );
};

Usage in CurrentEventPage:

typescript

import { MetaTags } from '@/components/SEO/MetaTags';

export const CurrentEventPage = () => {
  const { data: event } = useCurrentEvent();

  return (
    <PublicLayout>
      <MetaTags
        title={event?.title || 'Current Event'}
        description={event?.description || 'Join us for our next event'}
        image={event?.imageUrl}
        url={`https://batbern.ch/current-event`}
      />
      {/* ... rest of page */}
    </PublicLayout>
  );
};

JSON-LD Structured Data

EventSchema.tsx:

typescript

import { Helmet } from 'react-helmet-async';
import { Event } from '@/services/eventApi';

interface EventSchemaProps {
  event: Event;
}

export const EventSchema = ({ event }: EventSchemaProps) => {
  const schema = {
    '@context': 'https://schema.org',
    '@type': 'Event',
    name: event.title,
    description: event.description,
    startDate: `${event.startDate}T${event.startTime}`,
    endDate: `${event.endDate}T${event.endTime}`,
    eventStatus: 'https://schema.org/EventScheduled',
    eventAttendanceMode: 'https://schema.org/OfflineEventAttendanceMode',
    location: event.venue ? {
      '@type': 'Place',
      name: event.venue.name,
      address: {
        '@type': 'PostalAddress',
        streetAddress: event.venue.address,
        addressLocality: event.venue.city,
        addressCountry: 'CH',
      },
      geo: {
        '@type': 'GeoCoordinates',
        latitude: event.venue.coordinates.lat,
        longitude: event.venue.coordinates.lng,
      },
    } : undefined,
    offers: {
      '@type': 'Offer',
      price: '0',
      priceCurrency: 'CHF',
      availability: 'https://schema.org/InStock',
      url: `https://batbern.ch/register/${event.id}`,
    },
    organizer: {
      '@type': 'Organization',
      name: 'Berner Architekten Treffen',
      url: 'https://batbern.ch',
    },
  };

  return (
    <Helmet>
      <script type="application/ld+json">
        {JSON.stringify(schema)}
      </script>
    </Helmet>
  );
};

vite.config.ts:

typescript

import sitemap from 'vite-plugin-sitemap';

export default defineConfig({
  plugins: [
    react(),
    sitemap({
      hostname: 'https://batbern.ch',
      routes: [
        '/',
        '/current-event',

Performance (Lighthouse): ⚠️ NEEDS OPTIMIZATION (Score: 46/100)

Lighthouse Scores:
- Performance: 46/100 ⚠️ (Target: >90)
- Accessibility: 92/100 ✅
- Best Practices: 96/100 ✅
- SEO: 92/100 ✅
Core Web Vitals:
- FCP (First Contentful Paint): 3.4s ⚠️ (Target: <1.8s)
- LCP (Largest Contentful Paint): 15.5s ❌ (Target: <2.5s)
- TBT (Total Blocking Time): 10ms ✅ (Target: <200ms)
- CLS (Cumulative Layout Shift): 0.529 ❌ (Target: <0.1)
- Speed Index: 3.4s ⚠️ (Target: <3.4s)
Performance Issues Identified:
1. ⚠️ Unused JavaScript: 72% of MUI bundle unused (85KB wasted out of 118KB)
2. ⚠️ Large LCP: 15.5s - likely image loading or network latency
3. ⚠️ Layout Shifts: CLS 0.529 - layout not stable during load
4. ℹ️ Unused React DOM code (38% of 148KB bundle)
Performance Recommendations:
1. Code Splitting: Lazy-load MUI components not used on initial load
2. Image Optimization: Add size hints, lazy loading, use WebP format
3. CLS Fixes: Add explicit width/height to images, reserve space for dynamic content
4. CDN: Ensure CloudFront caching is optimized for assets
5. Bundle Analysis: Run npm run analyze to identify large dependencies

SEO: ✅ MOSTLY COMPLIANT (Score: 92/100)

✅ Document title present and correct
✅ Meta description present
✅ Canonical URL configured
✅ Crawlable links
❌ robots.txt issue: File not being served (SPA routing catches /robots.txt)
- Fix Required: Configure CloudFront/S3 to serve /robots.txt as static file
- Current behavior: Returns HTML index page instead of robots.txt

Accessibility: ✅ EXCELLENT (Score: 92/100)

✅ ARIA attributes valid
✅ Color contrast sufficient
✅ Semantic HTML structure
✅ Form labels associated
✅ Keyboard navigation supported
⚠️ Pending: Manual testing with axe DevTools (user to run)

Critical Issues to Fix Before Production

NOTE: These issues are tracked in Story 4.1.8a: Performance Optimization

❌ robots.txt not served: Configure S3/CloudFront to serve static file
⚠️ LCP 15.5s: Optimize images and critical rendering path
⚠️ CLS 0.529: Add image dimensions and stabilize layout
⚠️ Unused JS: Implement code splitting for MUI components

Follow-up Story: docs/stories/4.1.8a.performance-optimization.md

Next Steps

✅ Run E2E tests on staging - COMPLETED
✅ Run Lighthouse performance audit - COMPLETED
⏸️ Run accessibility audit with axe DevTools - USER ACTION REQUIRED
⚠️ Fix critical issues:
- Configure robots.txt serving in CloudFront/S3
- Optimize LCP (image lazy loading, CDN, compression)
- Fix CLS (explicit image dimensions)
- Implement code splitting
🔄 Re-run Lighthouse after fixes (target: >90 performance)
✅ Get stakeholder sign-off once performance targets met

Ready for Production When:

All tests green (E2E tests validated)
Staging tested and approved
Performance validated (LCP <1.5s, score >90)
SEO optimized (sitemap, robots.txt, meta tags)
Accessibility compliant (WCAG 2.1 AA)
