|
|
## 🔍 **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:**
|
|
```typescript
|
|
// 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:**
|
|
```typescript
|
|
// 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:**
|
|
```typescript
|
|
// 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
|
|
```

## ⚙️ **Technical Implementation Details**
|
|
|
|
### **Device Detection Logic:**
|
|
```typescript
|
|
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:**
|
|
```css
|
|
/* 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:**
|
|
```javascript
|
|
// Automatic viewport height calculation
|
|
const setViewportHeight = () => {
|
|
const vh = window.innerHeight * 0.01;
|
|
document.documentElement.style.setProperty('--vh', `${vh}px`);
|
|
};
|
|
```
