Code Review Improvements (Addressing PR #33 feedback)

🔴 High Priority Fixes (5/5 Complete)

• Accessibility Features:
  • Added skip-to-content link for keyboard navigation (Tab to reveal)
  • Active link styling with underline + bold + aria-current="page"
  • Semantic HTML: <header> and <main> elements
  • ARIA labels: aria-label="Nawigacja główna" on nav
  • Phone links: aria-label="Zadzwoń do [clinic name]"
• Loading/Error States: TanStack Query with loading, error, and empty state UIs
• Empty State Handling: Message displayed when no clinics available
• Mock Data Separation: Moved to /apps/web/src/data/mockClinics.ts
• Phone Links: Verified tel: protocol with space removal for compatibility

🟡 Medium Priority Fixes (4/7 Complete, 3 Deferred)

• ✅ SEO Metadata: Title, description, and Open Graph tags
• ✅ Type Safety: Navigation links use FileRouteTypes["fullPaths"]
• ✅ Performance: Memoized ClinicCard component with React.memo
• ✅ Empty State: Proper UI when clinics array is empty
• ⚠️ Responsive Nav: Deferred - current 2-link nav works on mobile

🟢 Low Priority Fixes (6/8 Complete)

• ✅ Component Extraction: Created ClinicCard component (179→113 lines)

Testing

✅ Accessibility Testing:

• Skip-to-content link appears on Tab focus with proper focus styling
• Active link styling (underline + bold) updates correctly when navigating
• ARIA labels present on navigation (aria-label="Nawigacja główna")
• Phone links include descriptive aria-labels

• Focus rings visible for keyboard navigation (WCAG compliant)

✅ Functionality Testing:

• All 5 clinics display correctly in responsive grid (2 cols md, 3 cols lg)
• Phone links use proper tel: protocol with spaces removed
• Loading state briefly shows "Ładowanie przychodni..." (100ms delay)
• Empty state shows "Brak dostępnych przychodni."
• Error state shows error message with proper styling
• All clinic information displays correctly (name, address, hours, phone)
• Tel protocol correctly triggers system dialer

✅ Interactive States:

• Card hover produces subtle shadow elevation effect (smooth transition)
• Phone numbers show underline on hover
• Phone links show focus ring on keyboard Tab navigation
• All hover/focus states provide clear visual feedback
• Browser status bar shows tel: URI on phone link hover

✅ Code Quality:

• Type-safe navigation links using generated FileRouteTypes
• Mock data properly separated to data/mockClinics.ts
• Proper error handling with TanStack Query
• SEO metadata configured (title visible in browser tab)
• Component extracted and memoized for performance
• Reduced code complexity: main component 179 → 113 lines (-37%)
• Proper TypeScript interfaces with exported types
