🔍 Root Causes & Solutions

Mobile Safari Endless Reloading Issue

Root Causes:

1. Performance Overload: Heavy backdrop-filter: blur(15px) causing GPU strain
2. Viewport Height Conflicts: Incompatible 100vh and 100dvh units
3. Reactive Update Loops: Complex onMounted() logic triggering re-renders
4. Background Image Performance: Large images causing memory pressure
5. Promise Chain Failures: API errors bubbling up and causing page reloads

Solutions Implemented:

// 1. Mobile Safari Detection System
utils/mobile-safari-utils.ts
- Device detection (mobile Safari, iOS, performance needs)
- Backdrop-filter disabling for problematic devices
- Viewport height optimization with CSS variables
- Performance utilities (throttle, debounce)
- Automatic CSS class application

// 2. Performance Optimizations
pages/signup.vue
- Dynamic CSS classes based on device capabilities
- Simplified onMounted() to prevent reload loops
- Better error handling that doesn't cause page reloads
- Fallback configurations to prevent undefined errors
- Mobile-specific viewport meta tag

// 3. Mobile Safari CSS Optimizations
.performance-optimized {
  backdrop-filter: none; /* Remove expensive filter */
  background: rgba(255, 255, 255, 0.98) !important;
  box-shadow: 0 4px 16px rgba(0, 0, 0, 0.2) !important;
  transition: none; /* Remove animations */
}

// 4. Viewport Height Fix
.is-mobile-safari {
  min-height: -webkit-fill-available;
  background-attachment: scroll !important;
}

Keycloak "Set Your Password" 404 Error

Root Causes:

1. Missing Public Config: keycloakIssuer not exposed to client-side
2. Incorrect URL Structure: Using hash fragments that don't exist
3. Wrong Realm Name: Using monacousa-portal instead of monacousa

Solutions Implemented:

// 1. Fixed Nuxt Config
nuxt.config.ts
public: {
  keycloakIssuer: process.env.NUXT_KEYCLOAK_ISSUER || 
    "https://auth.monacousa.org/realms/monacousa"
}

// 2. Fixed URL Generation
pages/auth/verify-success.vue
const setupPasswordUrl = computed(() => {
  const runtimeConfig = useRuntimeConfig();
  const keycloakIssuer = runtimeConfig.public.keycloakIssuer || 
    'https://auth.monacousa.org/realms/monacousa';
  
  // Fixed: Remove hash fragment that caused 404
  return `${keycloakIssuer}/account/`;
});

Country Dropdown Broken on Mobile

Root Causes:

1. Vuetify v-select Issues: Mobile Safari incompatibility with complex dropdown positioning
2. Z-index Conflicts: Dropdown overlapping with other form elements
3. Touch Interaction Problems: Poor touch responsiveness on mobile devices
4. Layout Disruption: Dropdown breaking the form layout and rendering incorrectly

Solutions Implemented:

// 1. Mobile-Optimized Country Selector
components/MultipleNationalityInput.vue
- Device detection to switch between desktop v-select and mobile dialog
- Full-screen country selection dialog for mobile Safari
- Touch-optimized interface with larger touch targets
- Search functionality with smooth scrolling

// 2. Mobile Dialog Interface
<v-dialog
  v-model="showMobileSelector"
  :fullscreen="useMobileInterface"
  :transition="'dialog-bottom-transition'"
  class="mobile-country-dialog"
>
  <!-- Full-screen country list with search -->
  <!-- Optimized for touch interaction -->
  <!-- Smooth iOS-style animations -->
</v-dialog>

// 3. Performance Optimizations
- Hardware acceleration for smooth scrolling
- Disabled transitions for performance mode
- Touch-friendly 60px minimum button heights
- -webkit-overflow-scrolling: touch for iOS

🚀 New Features Implemented

1. Device-Aware Optimization System

// Automatic device detection
const deviceInfo = getDeviceInfo();
const performanceMode = needsPerformanceOptimization();
const disableBackdropFilter = shouldDisableBackdropFilter();

// Dynamic CSS classes
const containerClasses = [
  'base-container',
  ...getOptimizedClasses()  // Adds: is-mobile, is-mobile-safari, performance-mode
].join(' ');

2. Progressive Performance Degradation

• High-performance devices: Full visual effects (backdrop-filter, animations)
• Mobile Safari: Disabled backdrop-filter, simplified backgrounds
• Performance mode: Removed animations, lighter shadows, no transitions

3. Viewport Height Optimization

/* Universal viewport height handling */
.container {
  min-height: 100vh;
  min-height: calc(var(--vh, 1vh) * 100); /* Mobile Safari fallback */
}

.is-mobile-safari .container {
  min-height: -webkit-fill-available;
}

4. Auto-Applied Mobile Safari Fixes

• Automatic viewport height calculation
• CSS class injection
• Resize event handling
• Route change optimization

⚙️ Technical Implementation Details

Device Detection Logic:

export function getDeviceInfo(): DeviceInfo {
  const userAgent = navigator.userAgent;
  const isMobile = /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(userAgent);
  const isIOS = /iPad|iPhone|iPod/.test(userAgent);
  const isSafari = /^((?!chrome|android).)*safari/i.test(userAgent);
  const isMobileSafari = isIOS && isSafari;
  
  return { isMobile, isSafari, isMobileSafari, isIOS, safariVersion };
}

CSS Performance Classes:

/* Applied automatically based on device detection */
.is-mobile { /* Mobile-specific optimizations */ }
.is-mobile-safari { /* Safari-specific fixes */ }
.is-ios { /* iOS-specific adjustments */ }
.performance-mode { /* Performance optimizations */ }

Viewport Height Handling:

// Automatic viewport height calculation
const setViewportHeight = () => {
  const vh = window.innerHeight * 0.01;
  document.documentElement.style.setProperty('--vh', `${vh}px`);
};
