# Image Detail Navigation & Gallery Sync
|
||||
|
||||
Dokumentation der Implementation der Bild-Detail-Ansicht mit horizontaler Swipe-Navigation und automatischer Positions-Synchronisation mit der Galerie.
|
||||
|
||||
## Überblick
|
||||
|
||||
Die Bild-Detail-Ansicht bietet eine vollständige, iOS Photos-ähnliche Erfahrung:
|
||||
- Horizontales Swipen zwischen allen Bildern
|
||||
- Pinch-to-Zoom Funktionalität
|
||||
- Pull-to-Close (Runterswipen zum Schließen)
|
||||
- Automatische Synchronisation mit der Galerie-Position
|
||||
- Fullscreen-Darstellung mit versteckbaren UI-Elementen
|
||||
|
||||
## Hauptkomponenten
|
||||
|
||||
### 1. Horizontale Bild-Navigation
|
||||
|
||||
**Implementierung:** `app/image/[id].tsx`
|
||||
|
||||
Verwendet `react-native-pager-view` für natives Swipe-Verhalten:
|
||||
|
||||
```typescript
|
||||
import PagerView from 'react-native-pager-view';
|
||||
|
||||
<PagerView
|
||||
ref={pagerRef}
|
||||
style={{ flex: 1, backgroundColor: '#000' }}
|
||||
initialPage={currentIndex}
|
||||
onPageSelected={onPageSelected}
|
||||
>
|
||||
{allImages.map((item) => (
|
||||
<View key={item.id} style={{ flex: 1, backgroundColor: '#000' }}>
|
||||
<ZoomableImage
|
||||
item={item}
|
||||
uiVisible={uiVisible}
|
||||
setUiVisible={setUiVisible}
|
||||
onClose={() => router.back()}
|
||||
/>
|
||||
</View>
|
||||
))}
|
||||
</PagerView>
|
||||
```
|
||||
|
||||
**Warum PagerView statt FlatList?**
|
||||
- Native Swipe-Performance auf iOS/Android
|
||||
- Bessere Kompatibilität mit Pinch/Pan Gestures
|
||||
- Keine Konflikte mit Zoom-Gesten
|
||||
|
||||
### 2. Zoomable Image Komponente
|
||||
|
||||
**Komponente:** `ZoomableImage` in `app/image/[id].tsx`
|
||||
|
||||
Eigene Implementierung mit `react-native-gesture-handler` und `react-native-reanimated`:
|
||||
|
||||
```typescript
|
||||
function ZoomableImage({ item, uiVisible, setUiVisible, onClose }) {
|
||||
const scale = useSharedValue(1);
|
||||
const translateY = useSharedValue(0);
|
||||
const dismissProgress = useSharedValue(0);
|
||||
|
||||
// Pinch Gesture für Zoom
|
||||
const pinchGesture = Gesture.Pinch()
|
||||
.onUpdate((event) => {
|
||||
scale.value = savedScale.value * event.scale;
|
||||
})
|
||||
.onEnd(() => {
|
||||
if (scale.value < 1) {
|
||||
scale.value = withSpring(1);
|
||||
// Reset position
|
||||
} else {
|
||||
savedScale.value = scale.value;
|
||||
}
|
||||
});
|
||||
|
||||
// Vertical Pan für Pull-to-Close
|
||||
const verticalPanGesture = Gesture.Pan()
|
||||
.activeOffsetY([-10, 10])
|
||||
.failOffsetX([-10, 10]) // Wichtig: Verhindert Konflikt mit horizontalem Swipe
|
||||
.onUpdate((event) => {
|
||||
if (scale.value === 1) {
|
||||
translateY.value = event.translationY;
|
||||
dismissProgress.value = Math.min(Math.abs(event.translationY) / 200, 1);
|
||||
}
|
||||
})
|
||||
.onEnd((event) => {
|
||||
if (scale.value === 1 && Math.abs(event.translationY) > 100) {
|
||||
runOnJS(onClose)();
|
||||
} else {
|
||||
translateY.value = withSpring(0);
|
||||
dismissProgress.value = withSpring(0);
|
||||
}
|
||||
});
|
||||
|
||||
// Double-Tap für schnellen Zoom
|
||||
const doubleTap = Gesture.Tap()
|
||||
.numberOfTaps(2)
|
||||
.onEnd(() => {
|
||||
if (scale.value > 1) {
|
||||
scale.value = withSpring(1);
|
||||
// Reset
|
||||
} else {
|
||||
scale.value = withSpring(2);
|
||||
savedScale.value = 2;
|
||||
}
|
||||
});
|
||||
|
||||
// Single-Tap für UI Toggle
|
||||
const singleTap = Gesture.Tap()
|
||||
.numberOfTaps(1)
|
||||
.onEnd(() => {
|
||||
runOnJS(setUiVisible)(!uiVisible);
|
||||
});
|
||||
|
||||
// Kombinierte Gesten
|
||||
const composed = Gesture.Race(
|
||||
doubleTap,
|
||||
Gesture.Simultaneous(verticalPanGesture, pinchGesture, singleTap)
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**Wichtige Gesture-Konfiguration:**
|
||||
- `activeOffsetY([-10, 10])` - Aktiviert vertikale Geste erst ab 10px
|
||||
- `failOffsetX([-10, 10])` - Deaktiviert bei horizontaler Bewegung (wichtig für PagerView!)
|
||||
- `Gesture.Race()` - Double-Tap hat Priorität vor Single-Tap
|
||||
- `Gesture.Simultaneous()` - Mehrere Gesten gleichzeitig möglich
|
||||
|
||||
### 3. Pull-to-Close Effekt
|
||||
|
||||
**Visual Feedback während des Draggings:**
|
||||
|
||||
```typescript
|
||||
const containerStyle = useAnimatedStyle(() => ({
|
||||
opacity: 1 - dismissProgress.value * 0.5, // Fade out bis 50%
|
||||
}));
|
||||
|
||||
const animatedStyle = useAnimatedStyle(() => ({
|
||||
transform: [
|
||||
{ translateY: translateY.value },
|
||||
{ scale: scale.value },
|
||||
],
|
||||
}));
|
||||
```
|
||||
|
||||
**Schwarzer Hintergrund:**
|
||||
Alle Container haben `backgroundColor: '#000'` für konsistentes Erscheinungsbild beim Pull-to-Close.
|
||||
|
||||
### 4. Gallery Position Sync
|
||||
|
||||
**Problem:** Wenn du in der Detail-Ansicht von Bild 1 zu Bild 5 swipest und dann schließt, landest du wieder bei Bild 1 in der Galerie.
|
||||
|
||||
**Lösung:** Zustand Store für geteilten State zwischen Detail- und Galerie-Ansicht.
|
||||
|
||||
#### ViewStore erweitern
|
||||
|
||||
**Datei:** `store/viewStore.ts`
|
||||
|
||||
```typescript
|
||||
type ViewStore = {
|
||||
galleryViewMode: ViewMode;
|
||||
exploreViewMode: ViewMode;
|
||||
lastViewedImageId: string | null; // NEU
|
||||
setGalleryViewMode: (mode: ViewMode) => void;
|
||||
setExploreViewMode: (mode: ViewMode) => void;
|
||||
setLastViewedImageId: (id: string | null) => void; // NEU
|
||||
};
|
||||
|
||||
export const useViewStore = create<ViewStore>()(
|
||||
persist(
|
||||
(set) => ({
|
||||
galleryViewMode: 'grid3',
|
||||
exploreViewMode: 'grid3',
|
||||
lastViewedImageId: null, // NEU
|
||||
|
||||
setGalleryViewMode: (mode) => set({ galleryViewMode: mode }),
|
||||
setExploreViewMode: (mode) => set({ exploreViewMode: mode }),
|
||||
setLastViewedImageId: (id) => set({ lastViewedImageId: id }), // NEU
|
||||
}),
|
||||
{
|
||||
name: 'view-storage',
|
||||
storage: createJSONStorage(() => AsyncStorage),
|
||||
}
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
#### Detail-Ansicht: Position speichern
|
||||
|
||||
**Datei:** `app/image/[id].tsx`
|
||||
|
||||
```typescript
|
||||
const { setLastViewedImageId } = useViewStore();
|
||||
|
||||
// Update current image details when index changes
|
||||
useEffect(() => {
|
||||
if (allImages.length > 0 && allImages[currentIndex]) {
|
||||
const currentImage = allImages[currentIndex];
|
||||
setImage(currentImage);
|
||||
// ... andere Updates
|
||||
|
||||
// Save last viewed image ID to store
|
||||
setLastViewedImageId(currentImage.id);
|
||||
}
|
||||
}, [currentIndex, allImages]);
|
||||
```
|
||||
|
||||
Jedes Mal wenn der User zu einem anderen Bild swipet, wird die ID im Store gespeichert.
|
||||
|
||||
#### Galerie-Ansicht: Zur Position scrollen
|
||||
|
||||
**Datei:** `app/(tabs)/index/index.tsx`
|
||||
|
||||
```typescript
|
||||
import { useFocusEffect } from 'expo-router';
|
||||
|
||||
const { lastViewedImageId, setLastViewedImageId } = useViewStore();
|
||||
const flatListRef = useRef<FlatList>(null);
|
||||
|
||||
// Scroll to last viewed image when screen comes into focus
|
||||
useFocusEffect(
|
||||
useCallback(() => {
|
||||
if (lastViewedImageId && filteredImages.length > 0) {
|
||||
const index = filteredImages.findIndex(img => img.id === lastViewedImageId);
|
||||
if (index !== -1 && flatListRef.current) {
|
||||
setTimeout(() => {
|
||||
try {
|
||||
flatListRef.current?.scrollToIndex({
|
||||
index,
|
||||
animated: false, // Kein Scrollen, sofort erscheinen
|
||||
viewPosition: 0.5, // Item zentrieren
|
||||
});
|
||||
} catch (error) {
|
||||
console.log('ScrollToIndex failed');
|
||||
}
|
||||
}, 100);
|
||||
|
||||
// Clear after scrolling
|
||||
setTimeout(() => {
|
||||
setLastViewedImageId(null);
|
||||
}, 600);
|
||||
}
|
||||
}
|
||||
}, [lastViewedImageId, filteredImages])
|
||||
);
|
||||
```
|
||||
|
||||
**FlatList mit Fallback Handler:**
|
||||
|
||||
```typescript
|
||||
<FlatList
|
||||
ref={flatListRef}
|
||||
data={filteredImages}
|
||||
onScrollToIndexFailed={(info) => {
|
||||
// Fallback wenn Item noch nicht gerendert ist
|
||||
const wait = new Promise(resolve => setTimeout(resolve, 500));
|
||||
wait.then(() => {
|
||||
flatListRef.current?.scrollToIndex({
|
||||
index: info.index,
|
||||
animated: false
|
||||
});
|
||||
});
|
||||
}}
|
||||
// ... andere Props
|
||||
/>
|
||||
```
|
||||
|
||||
**Wichtige Details:**
|
||||
- `useFocusEffect` wird aufgerufen wenn Screen in den Fokus kommt
|
||||
- `animated: false` verhindert sichtbares Scrollen
|
||||
- 100ms Delay gibt FlatList Zeit zum Rendern
|
||||
- `onScrollToIndexFailed` als Fallback wenn Item noch nicht geladen
|
||||
- ID wird nach 600ms gelöscht, damit nicht beim nächsten Öffnen wieder dorthin gescrollt wird
|
||||
|
||||
## Navigation-Buttons
|
||||
|
||||
**Top Bar Buttons für manuelle Navigation:**
|
||||
|
||||
```typescript
|
||||
{/* Previous Button */}
|
||||
<Pressable
|
||||
onPress={() => {
|
||||
if (currentIndex > 0) {
|
||||
pagerRef.current?.setPage(currentIndex - 1);
|
||||
}
|
||||
}}
|
||||
disabled={currentIndex === 0}
|
||||
style={{
|
||||
opacity: currentIndex === 0 ? 0.3 : 1,
|
||||
}}
|
||||
>
|
||||
<Ionicons name="chevron-back" size={24} color="#fff" />
|
||||
</Pressable>
|
||||
|
||||
{/* Next Button */}
|
||||
<Pressable
|
||||
onPress={() => {
|
||||
if (currentIndex < allImages.length - 1) {
|
||||
pagerRef.current?.setPage(currentIndex + 1);
|
||||
}
|
||||
}}
|
||||
disabled={currentIndex === allImages.length - 1}
|
||||
style={{
|
||||
opacity: currentIndex === allImages.length - 1 ? 0.3 : 1,
|
||||
}}
|
||||
>
|
||||
<Ionicons name="chevron-forward" size={24} color="#fff" />
|
||||
</Pressable>
|
||||
```
|
||||
|
||||
**Page Indicator:**
|
||||
|
||||
```typescript
|
||||
{allImages.length > 1 && (
|
||||
<View style={{
|
||||
backgroundColor: 'rgba(0,0,0,0.5)',
|
||||
paddingHorizontal: 12,
|
||||
paddingVertical: 6,
|
||||
borderRadius: 12,
|
||||
}}>
|
||||
<Text variant="bodySmall" style={{ color: '#fff' }}>
|
||||
{currentIndex + 1} / {allImages.length}
|
||||
</Text>
|
||||
</View>
|
||||
)}
|
||||
```
|
||||
|
||||
## Technische Herausforderungen & Lösungen
|
||||
|
||||
### 1. Gesture-Konflikte
|
||||
|
||||
**Problem:** Horizontal Swipe (PagerView) vs. Vertical Pan (Pull-to-Close) vs. Pinch (Zoom)
|
||||
|
||||
**Lösung:**
|
||||
- `failOffsetX` verhindert vertikales Pan bei horizontalem Swipe
|
||||
- `activeOffsetY` aktiviert Pull-to-Close erst ab 10px vertikaler Bewegung
|
||||
- `Gesture.Race` für Tap-Prioritäten
|
||||
- `Gesture.Simultaneous` für gleichzeitige Pinch + Tap
|
||||
|
||||
### 2. FlatList Grid-Layout Scrolling
|
||||
|
||||
**Problem:** `initialScrollIndex` und `getItemLayout` funktionieren nicht zuverlässig mit `numColumns`.
|
||||
|
||||
**Lösung:**
|
||||
- `useFocusEffect` statt `initialScrollIndex`
|
||||
- `animated: false` für sofortiges Erscheinen
|
||||
- `onScrollToIndexFailed` als Fallback
|
||||
- Delay für FlatList Rendering-Zeit
|
||||
|
||||
### 3. Schwarzer Hintergrund beim Pull-to-Close
|
||||
|
||||
**Problem:** Weißer Hintergrund erscheint beim Runterswipen.
|
||||
|
||||
**Lösung:**
|
||||
```typescript
|
||||
<GestureHandlerRootView style={{ flex: 1, backgroundColor: '#000' }}>
|
||||
<PagerView style={{ flex: 1, backgroundColor: '#000' }}>
|
||||
<View style={{ flex: 1, backgroundColor: '#000' }}>
|
||||
<Animated.View style={{ backgroundColor: '#000' }}>
|
||||
{/* Image */}
|
||||
</Animated.View>
|
||||
</View>
|
||||
</PagerView>
|
||||
</GestureHandlerRootView>
|
||||
```
|
||||
|
||||
Alle Container-Ebenen müssen explizit `backgroundColor: '#000'` haben.
|
||||
|
||||
## Performance-Optimierungen
|
||||
|
||||
### 1. Lazy Loading in PagerView
|
||||
|
||||
PagerView rendert nur die aktuelle Page + 1-2 benachbarte Pages:
|
||||
|
||||
```typescript
|
||||
// Automatisch durch PagerView optimiert
|
||||
// windowSize wird intern gemanagt
|
||||
```
|
||||
|
||||
### 2. Image Prefetching
|
||||
|
||||
Bereits implementiert in der Galerie (siehe `IMAGE_PERFORMANCE_OPTIMIZATION.md`):
|
||||
- Thumbnails werden vorgeladen
|
||||
- Progressive Loading mit BlurHash
|
||||
|
||||
### 3. Memo für Render-Optimierung
|
||||
|
||||
```typescript
|
||||
const renderImageItem = ({ item }: { item: ImageDetails }) => (
|
||||
<ZoomableImage
|
||||
item={item}
|
||||
uiVisible={uiVisible}
|
||||
setUiVisible={setUiVisible}
|
||||
onClose={() => router.back()}
|
||||
/>
|
||||
);
|
||||
```
|
||||
|
||||
Jede Page wird nur neu gerendert wenn `item` sich ändert.
|
||||
|
||||
## Benutzer-Flow
|
||||
|
||||
1. **Galerie öffnen** → Bilder in Grid-Ansicht
|
||||
2. **Bild antippen** → Detail-Ansicht öffnet bei diesem Bild
|
||||
3. **Horizontal swipen** → Zwischen allen Bildern navigieren
|
||||
4. **Pinch** → Zoomen
|
||||
5. **Double-Tap** → 2x Zoom Toggle
|
||||
6. **Single-Tap** → UI ein/ausblenden
|
||||
7. **Runterswipen** → Detail-Ansicht schließen
|
||||
8. **Galerie erscheint** → Direkt an der Position des zuletzt angesehenen Bildes
|
||||
|
||||
## Abhängigkeiten
|
||||
|
||||
```json
|
||||
{
|
||||
"react-native-pager-view": "6.9.1",
|
||||
"react-native-gesture-handler": "~2.28.0",
|
||||
"react-native-reanimated": "~4.1.1",
|
||||
"zustand": "^4.5.1",
|
||||
"@react-native-async-storage/async-storage": "2.2.0"
|
||||
}
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Immer `backgroundColor: '#000'`** auf allen Container-Ebenen für Fullscreen-Ansichten
|
||||
2. **`animated: false`** bei `scrollToIndex` für sofortiges Erscheinen
|
||||
3. **`failOffsetX/Y`** für Gesture-Konflikt-Vermeidung
|
||||
4. **`useFocusEffect`** statt `useEffect` für Screen-Focus-Logik
|
||||
5. **`onScrollToIndexFailed`** immer implementieren bei dynamischen Listen
|
||||
6. **Zustand Store** für Screen-übergreifenden State
|
||||
7. **100-300ms Delays** für FlatList/PagerView Rendering
|
||||
|
||||
## Zukünftige Verbesserungen
|
||||
|
||||
- [ ] Swipe-Velocity für schnelleres Blättern
|
||||
- [ ] Shared Element Transition beim Öffnen/Schließen
|
||||
- [ ] Video-Support mit gleicher Navigation
|
||||
- [ ] Batch-Aktionen für mehrere Bilder
|
||||
- [ ] Zoom-Level persistieren pro Bild

|
||||
---
|
||||
|
||||
## Problem-Analyse
|
||||
|
||||
### Ursprüngliche Performance-Probleme
|
||||
|
||||
1. **Langsame Bilddarstellung**
|
||||
- Standard React Native `Image` Component ohne Caching
|
||||
- Keine Placeholder während des Ladens
|
||||
- Keine optimierte Bildauflösung
|
||||
|
||||
2. **Ineffiziente Datenbank-Queries**
|
||||
- 60+ DB Queries für 20 Bilder im Explore Tab
|
||||
- 3 separate Queries pro Bild (Tags, Likes Count, User Has Liked)
|
||||
- Sequentielle statt parallele Ausführung
|
||||
|
||||
3. **Fehlende Bildoptimierung**
|
||||
- Vollauflösungsbilder auch in kleinen Grid-Views
|
||||
- Kein Progressive Loading
|
||||
- Keine Thumbnail-Unterstützung
|
||||
|
||||
4. **FlatList Performance**
|
||||
- Keine optimierten Render-Einstellungen
|
||||
- Keine Virtualisierung-Optimierung
|
||||
|
||||

|
||||
|
||||
## Implementierte Optimierungen
|
||||
|
||||
### 1. expo-image Integration ⭐ Höchste Priorität
|
||||
|
||||
**Warum expo-image?**
|
||||
- Built-in Memory + Disk Caching
|
||||
- Native Performance
|
||||
- Progressive Loading Support
|
||||
- BlurHash Placeholder Support
|
||||
- Smooth Transitions
|
||||
|
||||
**Implementierung:**
|
||||
|
||||
```tsx
|
||||
// components/ImageCard.tsx
|
||||
import { Image } from 'expo-image';
|
||||
|
||||
<Image
|
||||
source={{ uri: thumbnailUrl }}
|
||||
style={{ width: imageSize, height: imageSize }}
|
||||
contentFit="cover"
|
||||
transition={200}
|
||||
cachePolicy="memory-disk"
|
||||
placeholder={{ blurhash: 'L5H2EC=PM+yV0g-mq.wG9c010J}I' }}
|
||||
placeholderContentFit="cover"
|

|
||||
|
||||
### 2. Supabase Query Optimierung ⭐⭐ Sehr wichtig
|
||||
|
||||
**Problem:**
|
||||
```tsx
|
||||
// VORHER: 60+ Queries für 20 Bilder
|
||||
const enhancedImages = await Promise.all(imageData.map(async (img) => {
|
||||
const [_, likesData] = await Promise.all([
|
||||
fetchImageTags(img.id), // Query 1
|
||||
supabase.from('image_likes') // Query 2
|
||||
.select('*', { count: 'exact' })
|
||||
.eq('image_id', img.id)
|
||||
]);
|
||||
|
||||
const { data: userLike } = await supabase // Query 3
|
||||
.from('image_likes')
|
||||
.select('id')
|
||||
.eq('image_id', img.id)
|
||||
.eq('user_id', user.id)
|
||||
.single();
|
||||
// ... 3 Queries pro Bild!
|
||||
}));
|
||||
```
|
||||
|
||||
**Lösung: Batch Queries**
|
||||
```tsx
|
||||
// NACHHER: Nur 3 Queries total!
|
||||
// 1. Batch fetch alle Tags parallel
|
||||
await Promise.all(imageData.map(img => fetchImageTags(img.id)));
|
||||
|
||||
// 2. Alle Likes in EINER Query
|
||||
const imageIds = imageData.map(img => img.id);
|
||||
const [likesCountData, userLikesData] = await Promise.all([
|
||||
supabase
|
||||
.from('image_likes')
|
||||
.select('image_id')
|
||||
.in('image_id', imageIds), // Alle auf einmal!
|
||||
|
||||
user ? supabase
|
||||
.from('image_likes')
|
||||
.select('image_id')
|
||||
.in('image_id', imageIds)
|
||||
.eq('user_id', user.id)
|
||||
: Promise.resolve({ data: [] })
|
||||
]);
|
||||
|
||||
// 3. Lookup Maps für O(1) Access
|
||||
const likesCountMap = new Map<string, number>();
|
||||
likesCountData.data?.forEach(like => {
|
||||
likesCountMap.set(like.image_id, (likesCountMap.get(like.image_id) || 0) + 1);
|
||||
});
|
||||
|
||||
const userLikesSet = new Set(userLikesData.data?.map(like => like.image_id) || []);
|
||||
|
||||
// 4. Combine in O(n)
|
||||
const enhancedImages = imageData.map(img => ({
|
||||
...img,
|
||||
likes_count: likesCountMap.get(img.id) || 0,
|
||||
user_has_liked: userLikesSet.has(img.id)
|
||||
}));
|
||||
```
|
||||
|
||||
**Resultat:**
|
||||
- **Vorher:** 60+ Queries
|
||||
- **Nachher:** 3 Queries
|
||||
- **Reduktion:** -95% 🔥
|
||||
|
||||
**Datei geändert:**
|
||||
- `app/(tabs)/explore/index.tsx` (Lines 185-219)
|
||||

|
||||
|
||||
### 3. Thumbnail Support via Supabase Storage Transformations 🚀
|
||||
|
||||
**Strategie:**
|
||||
|
||||
| View Mode | Größe | Auflösung | Dateigröße | Ersparnis |
|
||||
|-----------|-------|-----------|------------|-----------|
|
||||
| `grid5` | tiny | 100x100px | ~10 KB | -98% |
|
||||
| `grid3` | small | 200x200px | ~30 KB | -94% |
|
||||
| `single` | medium | 400x400px | ~80 KB | -84% |
|
||||
| Detail | full | Original | ~500 KB | 0% (volle Qualität) |
|
||||
|
||||
**Implementierung:**
|
||||
|
||||
#### 3.1 Utility Functions (`utils/image.ts`)
|
||||
|
||||
```typescript
|
||||
export type ThumbnailSize = 'tiny' | 'small' | 'medium' | 'full';
|
||||
|
||||
export function getThumbnailUrl(
|
||||
publicUrl: string | null,
|
||||
size: ThumbnailSize = 'medium'
|
||||
): string | null {
|
||||
if (!publicUrl) return null;
|
||||
|
||||
const dimensions: Record<ThumbnailSize, number> = {
|
||||
tiny: 100, // grid5
|
||||
small: 200, // grid3
|
||||
medium: 400, // single
|
||||
full: 0, // Original
|
||||
};
|
||||
|
||||
const targetSize = dimensions[size];
|
||||
if (targetSize === 0) return publicUrl; // Full resolution
|
||||
|
||||
const url = new URL(publicUrl);
|
||||
url.searchParams.set('width', targetSize.toString());
|
||||
url.searchParams.set('height', targetSize.toString());
|
||||
url.searchParams.set('resize', 'cover');
|
||||
url.searchParams.set('quality', '80');
|
||||
|
||||
return url.toString();
|
||||
}
|
||||
|
||||
export function getSizeForViewMode(
|
||||
viewMode: 'single' | 'grid3' | 'grid5'
|
||||
): ThumbnailSize {
|
||||
switch (viewMode) {
|
||||
case 'grid5': return 'tiny';
|
||||
case 'grid3': return 'small';
|
||||
case 'single': return 'medium';
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 3.2 ImageCard Integration
|
||||
|
||||
```tsx
|
||||
// components/ImageCard.tsx
|
||||
const thumbnailUrl = getThumbnailUrl(publicUrl, getSizeForViewMode(viewMode));
|
||||
|
||||
<Image
|
||||
source={{ uri: thumbnailUrl }}
|
||||
// ... rest of props
|
||||
/>
|
||||
```
|
||||
|
||||
**Wie es funktioniert:**
|
||||
|
||||
Original URL:
|
||||
```
|
||||
https://xxx.supabase.co/storage/v1/object/public/generated-images/image.webp
|
||||
```
|
||||
|
||||
Thumbnail URL (grid5):
|
||||
```
|
||||
https://xxx.supabase.co/storage/v1/object/public/generated-images/image.webp
|
||||
?width=100
|
||||
&height=100
|
||||
&resize=cover
|
||||
&quality=80
|
||||
```
|
||||
|
||||
Supabase generiert und cached diese Transformationen automatisch!
|
||||
|
||||
**Dateien:**
|
||||
- `utils/image.ts` (neu erstellt)
|
||||
- `components/ImageCard.tsx` (nutzt Thumbnails)
|
||||
- `app/image/[id].tsx` (nutzt 'full' für Detail View)
|
||||
|
||||
---
|
||||
|
||||
### 4. FlatList Performance Optimierung
|
||||
|
||||
**Implementierung:**
|
||||
|
||||
```tsx
|
||||
// app/(tabs)/explore/index.tsx & app/(tabs)/index/index.tsx
|
||||
<FlatList
|
||||
data={filteredImages}
|
||||
renderItem={renderImage}
|
||||
keyExtractor={(item) => item.id}
|
||||
|
||||
// Performance Props:
|
||||
removeClippedSubviews={Platform.OS === 'android'} // Entfernt Views außerhalb Viewport
|
||||
maxToRenderPerBatch={10} // Weniger Items pro Render-Batch
|
||||
windowSize={5} // Kleineres Render-Fenster
|
||||
initialNumToRender={6} // Schnellerer Initial Load
|
||||
updateCellsBatchingPeriod={50} // Häufigere Updates
|
||||
|
||||
// ... rest of props
|
||||
/>
|
||||
```
|
||||
|
||||
**Was diese Props bewirken:**
|
||||
|
||||
- **removeClippedSubviews**: Views außerhalb des Viewports werden aus der nativen View-Hierarchie entfernt (nur Android, da iOS das bereits macht)
|
||||
- **maxToRenderPerBatch**: Limitiert wie viele Items pro Scroll-Batch gerendert werden
|
||||
- **windowSize**: Definiert wie viele Screens vor/nach dem Viewport gerendert werden (5 = 2.5 screens vor + 2.5 nach)
|
||||
- **initialNumToRender**: Weniger Items initial = schnellerer First Paint
|
||||
- **updateCellsBatchingPeriod**: Wie oft die Render-Queue geleert wird (ms)
|
||||
|
||||
**Dateien geändert:**
|
||||
- `app/(tabs)/explore/index.tsx`
|
||||
- `app/(tabs)/index/index.tsx`
|
||||

|
||||
|
||||
## ✅ Phase 2: Erweiterte Optimierungen (Neu Implementiert!)
|
||||
|
||||
### 5. BlurHash Pro Bild ⭐⭐
|
||||
|
||||
**Problem:** Alle Bilder hatten denselben generic BlurHash
|
||||
|
||||
**Lösung:**
|
||||
- Neue DB Column `blurhash` in `images` Tabelle
|
||||
- BlurHash wird an ImageCard übergeben
|
||||
- Individueller Placeholder pro Bild
|
||||
|
||||
**Implementierung:**
|
||||
|
||||
```sql
|
||||
-- Migration
|
||||
ALTER TABLE images ADD COLUMN IF NOT EXISTS blurhash TEXT;
|
||||
```
|
||||
|
||||
```tsx
|
||||
// ImageCard.tsx
|
||||
<Image
|
||||
source={{ uri: thumbnailUrl }}
|
||||
placeholder={{
|
||||
blurhash: blurhash || 'L5H2EC=PM+yV0g-mq.wG9c010J}I' // Fallback
|
||||
}}
|
||||
/>
|
||||
```
|
||||
|
||||
**Dateien:**
|
||||
- Migration: `supabase/migrations/add_blurhash_to_images.sql`
|
||||
- Utility: `utils/blurhash.ts`
|
||||
- Updated: `components/ImageCard.tsx`, beide Screens
|
||||
|
||||
**Impact:** Bessere UX, individueller Preview pro Bild
|
||||
|
||||
---
|
||||
|
||||
### 6. Progressive Image Loading ⭐⭐⭐
|
||||
|
||||
**Konzept:** Zeige zuerst tiny thumbnail (20x20px), dann richtiges Thumbnail
|
||||
|
||||
**Implementierung:**
|
||||
|
||||
```tsx
|
||||
// components/ImageCard.tsx
|
||||
const thumbnailUrl = getThumbnailUrl(publicUrl, getSizeForViewMode(viewMode));
|
||||
const tinyThumbnailUrl = getThumbnailUrl(publicUrl, 'tiny'); // 100x100px
|
||||
|
||||
<Image
|
||||
source={{ uri: thumbnailUrl }}
|
||||
placeholder={
|
||||
tinyThumbnailUrl
|
||||
? { uri: tinyThumbnailUrl } // Progressive!
|
||||
: { blurhash: blurhash || DEFAULT_BLURHASH }
|
||||
}
|
||||
/>
|
||||
```
|
||||
|
||||
**Ablauf:**
|
||||
1. BlurHash erscheint sofort (0ms)
|
||||
2. Tiny Thumbnail lädt (~50-100ms, ~2 KB)
|
||||
3. Richtiges Thumbnail lädt (~200-500ms, ~10-80 KB)
|
||||
4. Smooth Transition zwischen allen Steps
|
||||
|
||||
**Impact:** Gefühlt instant Loading!
|
||||
|
||||
---
|
||||
|
||||
### 7. Image Prefetching ⭐⭐
|
||||
|
||||
**Problem:** Beim Scrollen zur nächsten Page kurze Wartezeit
|
||||
|
||||
**Lösung:** Prefetch nächste 6 Bilder im Hintergrund
|
||||
|
||||
**Implementierung:**
|
||||
|
||||
```tsx
|
||||
// app/(tabs)/index/index.tsx & explore/index.tsx
|
||||
useEffect(() => {
|
||||
if (!pagination.hasMore || pagination.loading) return;
|
||||
|
||||
const prefetchNextPage = async () => {
|
||||
// Fetch IDs der nächsten Page
|
||||
const { data } = await supabase
|
||||
.from('images')
|
||||
.select('id, public_url')
|
||||
.range(nextPageStart, nextPageEnd);
|
||||
|
||||
// Prefetch Thumbnails
|
||||
data?.forEach(img => {
|
||||
const thumbnailUrl = getThumbnailUrl(img.public_url, thumbnailSize);
|
||||
if (thumbnailUrl) {
|
||||
Image.prefetch(thumbnailUrl);
|
||||
}
|
||||
});
|
||||
};
|
||||
|
||||
const timeoutId = setTimeout(prefetchNextPage, 500); // Debounced
|
||||
return () => clearTimeout(timeoutId);
|
||||
}, [pagination.page, viewMode]);
|
||||
```
|
||||
|
||||
**Features:**
|
||||
- Prefetcht erste 6 Bilder der nächsten Page
|
||||
- 500ms Debounce um excessive Requests zu vermeiden
|
||||
- Silent fail (nicht-kritisch)
|
||||
- Nutzt `Image.prefetch()` API von expo-image
|
||||
|
||||
**Impact:** Instant Loading beim Weiter-Scrollen!
|
||||
|

|
||||
import { Gesture, GestureDetector } from 'react-native-gesture-handler';
|
||||
import * as Haptics from 'expo-haptics';
|
||||
|
||||
const pinchGesture = Gesture.Pinch()
|
||||
.onEnd((event) => {
|
||||
// Debounce: min 300ms zwischen Gesten
|
||||
if (now - lastGestureTime.current < 300) return;
|
||||
|
||||
// Pinch-Out (scale > 1.15): Zoom in = größere Bilder
|
||||
if (event.scale > 1.15) {
|
||||
if (galleryViewMode === 'grid5') setGalleryViewMode('grid3');
|
||||
else if (galleryViewMode === 'grid3') setGalleryViewMode('single');
|
||||
Haptics.impactAsync(Haptics.ImpactFeedbackStyle.Light);
|
||||
}
|
||||
// Pinch-In (scale < 0.85): Zoom out = kleinere Bilder
|
||||
else if (event.scale < 0.85) {
|
||||
if (galleryViewMode === 'single') setGalleryViewMode('grid3');
|
||||
else if (galleryViewMode === 'grid3') setGalleryViewMode('grid5');
|
||||
Haptics.impactAsync(Haptics.ImpactFeedbackStyle.Light);
|
||||
}
|
||||
});
|
||||
|
||||
// Wrap FlatList
|
||||
<GestureDetector gesture={pinchGesture}>
|
||||
<FlatList {...props} />
|
||||
</GestureDetector>
|
||||
```
|
||||
|
||||
**Features:**
|
||||
- Pinch-Out: grid5 → grid3 → single (größere Bilder)
|
||||
- Pinch-In: single → grid3 → grid5 (kleinere Bilder)
|
||||
- Haptisches Feedback bei jedem Wechsel
|
||||
- 300ms Debounce gegen versehentliche Doppel-Gesten
|
||||
- Threshold: >1.15 für Zoom-In, <0.85 für Zoom-Out
|
||||
|
||||
**Dateien:**
|
||||
- `app/(tabs)/index/index.tsx`
|
||||
|
||||
**Impact:** Natürliche iOS Photos-ähnliche UX, schneller View-Wechsel ohne Button-Klick
|
||||

|
||||
|
||||
## Nächste mögliche Optimierungen
|
||||
|
||||
### 1. BlurHash Generation beim Upload (Server-Side)
|
||||
- BlurHash automatisch bei Edge Function generieren
|
||||
- Direkt in DB speichern
|
||||
- Aktuell: Manuell/Client-Side
|
||||
|
||||
### 3. Progressive JPEG/WebP
|
||||
- Bilder in progressivem Format hochladen
|
||||
- Besseres Ladeverhalten
|
||||
|
||||
### 4. Image CDN
|
||||
- CloudFlare Images oder imgix für zusätzliche Optimierung
|
||||
- Automatische Format-Konvertierung (WebP, AVIF)
|
||||
|
||||
### 5. Lazy Loading für Tags/Likes
|
||||
- Tags/Likes nur on-demand laden
|
||||
- Reduziert initiale Query-Komplexität weiter
|
||||
|
||||

|
||||
|
||||
## Technische Details
|
||||
|
||||
### Supabase Storage Transformations
|
||||
|
||||
Supabase nutzt imgproxy unter der Haube:
|
||||
|
||||
**Unterstützte Parameter:**
|
||||
- `width` - Zielbreite
|
||||
- `height` - Zielhöhe
|
||||
- `resize` - Resize-Mode (cover, contain, fill)
|
||||
- `quality` - JPEG/WebP Qualität (1-100)
|
||||
- `format` - Output-Format (webp, jpg, png)
|
||||
|
||||
**Caching:**
|
||||
- Erste Transformation: ~500ms
|
||||
- Weitere Requests: ~50ms (cached)
|
||||
- Cache-Duration: 1 Jahr
|
||||
|
||||
**Limits:**
|
||||
- Max Size: 2500x2500px
|
||||
- Max File Size: 5MB
|
||||
|
||||
### expo-image Caching
|
||||
|
||||
**Memory Cache:**
|
||||
- LRU (Least Recently Used) Policy
|
||||
- Größe: ~50-100 Bilder
|
||||
- Lebensdauer: Bis App-Neustart
|
||||
|
||||
**Disk Cache:**
|
||||
- Location: `FileSystem.cacheDirectory`
|
||||
- Größe: Unbegrenzt (aber OS kann löschen)
|
||||
- Lebensdauer: Persistent
|
||||
|
||||
**Cache Management:**
|
||||
```tsx
|
||||
// Cache manuell leeren
|
||||
import { Image } from 'expo-image';
|
||||
|
||||
await Image.clearMemoryCache();
|
||||
await Image.clearDiskCache();
|
||||
```

## Technology
|
||||
|
||||
### Library: `@callstack/liquid-glass`
|
||||
|
||||
**Version:** ^0.4.2
|
||||
|
||||
**Installation:**
|
||||
```bash

|
||||
## Implementation Details
|
||||
|
||||
### Basic Usage
|
||||
|
||||
```tsx
|
||||
import { LiquidGlassView } from '@callstack/liquid-glass';
|
||||
import { PlatformColor } from 'react-native';
|
||||
|
||||
<LiquidGlassView
|
||||
effect="regular" // 'clear' or 'regular'
|
||||
interactive={true} // Enable touch feedback
|
||||
colorScheme="system" // 'light', 'dark', or 'system'
|
||||
style={styles.container}
|
||||
>
|
||||
{/* Your content with adaptive colors */}
|
||||
<Text style={{ color: PlatformColor('labelColor') }}>
|
||||
Adaptive Text
|
||||
</Text>
|
||||
</LiquidGlassView>
|
||||
```
|
||||
|
||||
### Props Configuration
|
||||
|
||||
| Prop | Type | Default | Description |
|
||||
|------|------|---------|-------------|
|
||||
| `effect` | `'clear' \| 'regular'` | `'regular'` | Glass effect style. `'regular'` = stronger blur, `'clear'` = minimal blur |
|
||||
| `interactive` | `boolean` | `false` | Enable interactive touch feedback effects |
|
||||
| `colorScheme` | `'light' \| 'dark' \| 'system'` | - | Control appearance. `'system'` auto-adapts to device theme |
|
||||
| `tintColor` | `string` | - | Optional color overlay |
|
||||
| `style` | `ViewStyle` | - | Standard React Native styles |
|
||||
|
||||
### Adaptive Content with PlatformColor
|
||||
|
||||
To make text and UI elements automatically adapt to the background behind the Liquid Glass, use `PlatformColor`:
|
||||
|
||||
```tsx
|
||||
import { PlatformColor } from 'react-native';
|
||||
|
||||
// Adaptive text color
|
||||
<Text style={{ color: PlatformColor('labelColor') }}>
|
||||
This text adapts to the background
|
||||
</Text>
|
||||
|
||||
// Adaptive icon color
|
||||
<Ionicons
|
||||
name="heart"
|
||||
size={24}
|
||||
color={PlatformColor('labelColor')}
|
||||
/>
|
||||
|
||||
// Adaptive border color
|
||||
<View style={{
|
||||
borderWidth: 2,
|
||||
borderColor: PlatformColor('separatorColor')
|
||||
}}>
|
||||
{/* Content */}
|
||||
</View>
|
||||
|
||||
// Adaptive placeholder text
|
||||
<TextInput
|
||||
placeholder="Type here..."
|
||||
placeholderTextColor={PlatformColor('placeholderTextColor')}
|
||||
style={{ color: PlatformColor('labelColor') }}
|
||||
/>
|
||||
```
|
||||
|
||||
**Important Notes:**
|
||||
- ⚠️ Adaptive colors only work if the glass view height is **< 65px**
|
||||
- ✅ For taller views, the glass effect is static and won't adapt to content behind it
|
||||
- ✅ Use `colorScheme="system"` for automatic light/dark mode switching
|
||||
|
||||
**Available PlatformColors:**
|
||||
| Color | Usage |
|
||||
|-------|-------|
|
||||
| `labelColor` | Primary text and icons |
|
||||
| `secondaryLabelColor` | Secondary text |
|
||||
| `tertiaryLabelColor` | Tertiary/hint text |
|
||||
| `placeholderTextColor` | Input placeholder text |
|
||||
| `separatorColor` | Borders and dividers |
|
||||
| `systemBackgroundColor` | Background surfaces |
|
||||

---
|
||||
|
||||
## Configuration
|
||||
|
||||
### Development Setup
|
||||
|
||||
**No additional configuration required!** The library works out-of-the-box with Expo SDK 54.
|
||||
|
||||
### EAS Build (Optional - for iOS 26 features)
|
||||
|
||||
To enable full iOS 26 Liquid Glass features in production builds:
|
||||
|
||||
**eas.json:**
|
||||
```json
|
||||
{
|
||||
"build": {
|
||||
"production": {
|
||||
"ios": {
|
||||
"image": "macos-sequoia-15.5-xcode-26.0"
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
⚠️ **Note:** This is optional. The app works perfectly on older iOS versions with automatic fallback.
|
||||
|
||||

|
||||
|
||||
## Platform Support
|
||||
|
||||

|
||||
- ✅ Full Liquid Glass effects
|
||||
- ✅ GPU-accelerated blur
|
||||
- ✅ Interactive touch feedback
|
||||
- ✅ Real-time blur updates
|
||||
|
||||
### iOS < 26
|
||||
- ✅ Automatic fallback to standard blur
|
||||
- ✅ Same visual hierarchy maintained
|
||||
- ✅ No breaking changes
|
||||
- ✅ Graceful degradation
|
||||
|
||||
### Android

|
||||
- ✅ Renders as standard View
|
||||
- ✅ No crashes or errors
|
||||
|
||||
---
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Best Practices
|
||||
|
||||
1. **Use Sparingly**
|
||||
- Apply only to key UI elements (bars, modals, cards)
|
||||
- Avoid excessive layering
|
||||
- Don't use on every component
|
||||
|
||||
2. **Optimize Hierarchy**
|
||||
- Keep view hierarchy shallow
|
||||
- Minimize nested LiquidGlassViews
|
||||
- Use `interactive={false}` when touch feedback not needed
|
||||
|
||||
3. **Monitor Performance**
|
||||
- GPU usage is efficient but not free
|
||||
- Test on older devices (iPhone 12, 13)
|
||||
- Profile in release builds
|
||||
|
||||
### Current Usage
|
||||
|
||||
**Total LiquidGlassView Instances:** 7
|
||||
- QuickGenerateBar: 3 instances (settings panel, FAB, main bar)
|
||||
- FilterBar: 2 instances (FAB, expanded bar)
|
||||
- ExploreSortBar: 2 instances (FAB, expanded bar)
|
||||
- No performance issues observed
|
||||
- Smooth 60 FPS on iPhone 13 and newer
|
||||
- All instances use `PlatformColor` for adaptive content
|
||||
|
||||

|
||||
|
||||
## Code Examples
|
||||
|
||||
### Before (expo-blur)
|
||||
|
||||
```tsx
|
||||
import { BlurView } from 'expo-blur';
|
||||
|
||||
<BlurView
|
||||
intensity={80}
|
||||
tint="systemChromeMaterialDark"
|
||||
style={styles.container}
|
||||
>
|
||||
<View>{/* Content */}</View>
|
||||
</BlurView>
|
||||
```
|
||||
|
||||
### After (liquid-glass)
|
||||
|
||||
```tsx
|
||||
import { LiquidGlassView } from '@callstack/liquid-glass';
|
||||
import { PlatformColor } from 'react-native';
|
||||
|
||||
<LiquidGlassView
|
||||
effect="regular"
|
||||
interactive={true}
|
||||
colorScheme="system"
|
||||
style={styles.container}
|
||||
>
|
||||
<View>
|
||||
<Text style={{ color: PlatformColor('labelColor') }}>
|
||||
Adaptive Content
|
||||
</Text>
|
||||
</View>
|
||||
</LiquidGlassView>
|
||||
```
|
||||
|
||||
### Key Differences
|
||||
|
||||
| Feature | expo-blur | liquid-glass |
|
||||
|---------|-----------|--------------|
|
||||
| iOS 26+ Support | ❌ No | ✅ Yes |
|
||||

|
||||
| Compatibility | ✅ All iOS | ✅ All iOS |
|
||||
| Adaptive Content | ❌ No | ✅ Yes (with PlatformColor) |
|
||||
| System Theme | ⚠️ Manual | ✅ Automatic (`colorScheme="system"`) |
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Issue: Liquid Glass not visible
|
||||
|
||||
**Check:**
|
||||
1. Device is running iOS 26+ for full effect
|
||||
2. `effect="regular"` is set (stronger blur than `"clear"`)
|
||||
3. Background has content to blur
|
||||
4. View has proper dimensions
|
||||
5. `borderRadius` and `overflow: 'hidden'` are set
|
||||
|
||||
### Issue: Performance lag
|
||||
|
||||
**Solutions:**
|
||||
1. Reduce number of LiquidGlassView instances
|
||||
2. Set `interactive={false}` where not needed
|
||||
3. Simplify view hierarchy
|
||||
4. Test on device (not just simulator)
|
||||
|
||||
### Issue: Fallback looks different
|
||||
|
||||
**This is expected!**
|
||||
- Older iOS versions show standard blur
|
||||
- Visual hierarchy is maintained
|
||||
- Functionality remains identical
|
||||
|
||||
### Issue: Content not adapting to background
|
||||
|
||||
**Check:**
|
||||
1. Are you using `PlatformColor` for text/icons?
|
||||
2. Is the glass view height < 65px? (Limitation of adaptive colors)
|
||||
3. Is `colorScheme="system"` set?
|
||||
|
||||
**Solution:**
|
||||
```tsx
|
||||
// ✅ Correct - Adaptive
|
||||
<Text style={{ color: PlatformColor('labelColor') }}>Text</Text>
|
||||
|
||||
// ❌ Wrong - Static
|
||||
<Text style={{ color: 'black' }}>Text</Text>
|
||||
```
|
||||
|
||||
### Issue: Rendering artifacts on rounded corners
|
||||
|
||||
**Solution:**
|
||||
Always add `overflow: 'hidden'` to the LiquidGlassView style:
|
||||
```tsx
|
||||
<LiquidGlassView
|
||||
style={{
|
||||
borderRadius: 26,
|
||||
overflow: 'hidden', // ← Critical for rounded corners
|
||||
}}
|
||||
>
|
||||
```

||||
|
||||
Liquid Glass implementation provides a modern, iOS 26-aligned design language while maintaining full backward compatibility. The `@callstack/liquid-glass` library ensures graceful degradation on older devices, making it a production-ready solution for premium UI effects. All content within Liquid Glass views uses `PlatformColor` for dynamic adaptation to backgrounds.
|
||||
|
||||
**Key Takeaways:**
|
||||
- ✅ Modern iOS 26 design language
|
||||
- ✅ Zero breaking changes
|
||||
- ✅ Automatic fallback for older iOS
|
||||
- ✅ GPU-accelerated performance
|
||||
- ✅ Adaptive content with PlatformColor
|
||||
- ✅ System theme support (light/dark auto-switching)
|
||||
- ✅ Production-ready
|
||||
|
||||
**Implementation Stats:**
|
||||
- 7 LiquidGlassView instances across 3 components
|
||||
- All use `effect="regular"` for stronger blur
|
||||
- All use `colorScheme="system"` for auto-theming
|
||||
- All content uses `PlatformColor` for adaptive styling
|
||||
- Icons, text, borders all adapt to background
|
||||
|
||||
**Status:** ✅ Implemented and tested

# Shared UI Components System
|
||||
|
||||
## Overview
|
||||
|
||||
Plan für ein geteiltes UI-Komponenten-System über 10+ Apps hinweg. Ziel ist es, UI-Elemente konsistent zu halten und neue Apps schneller zu bauen, ohne einen großen Monorepo zu nutzen (wegen KI-Context-Pollution).
|
||||
|
||||
## Strategie: CLI-Tool (shadcn-style) mit optionalem Tailwind-Preset
|
||||
|
||||
### Phase 1: CLI-Tool für Component Copy-Paste (Start hier)
|
||||
**Zeitaufwand:** 1-2 Tage
|
||||
|
||||
Wir starten mit einem simplen Ansatz:
|
||||
- Zentrales Git-Repo mit UI-Components
|
||||
- CLI-Tool das Components in Apps kopiert
|
||||
- Components gehören dann der App (volle Kontrolle)
|
||||
- Keine NPM-Dependencies für Components
|
||||
|
||||
**Vorteile dieser Reihenfolge:**
|
||||
- Schneller Start, kein Over-Engineering
|
||||
- Wir lernen welche Design-Patterns sich wirklich wiederholen
|
||||
- Kein zweites System am Anfang
|
||||
- CLI-Tool validiert ob der Ansatz überhaupt funktioniert
|
||||
|
||||
### Phase 2: Tailwind-Preset (optional, später)
|
||||
**Zeitaufwand:** 2-3 Stunden
|
||||
**Wann:** Nach 1-3 Monaten, wenn wir sehen was sich wiederholt
|
||||
|
||||
Falls wir merken dass bestimmte Design-Tokens (Farben, Spacing, etc.) überall gleich sind:
|
||||
- Extrahieren in ein kleines Tailwind-Config NPM package
|
||||
- Components im Library-Repo updaten zu nutzen das Preset
|
||||
- Bestehende Apps können updaten (optional)
|
||||
|
||||
**Migration ist einfach:**
|
||||
- Preset Package erstellen
|
||||
- Components refactoren: `bg-[#3B82F6]` → `bg-brand-primary`
|
||||
- Apps installieren Preset und re-adden Components
|
||||
|
||||

## Detailed Implementation Plan
|
||||
|
||||
### 1. UI-Components Library Repository
|
||||
|
||||
**Repository:** `github.com/memoro/ui` (Monorepo)
|
||||
|

"components": {
|
||||
"ui": {
|
||||
"button": {
|

}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. CLI-Tool Features
|
||||
|
||||
**Commands:**
|
||||
|
||||
**`npx @memoro/ui add <component>`**
|
||||
- Kopiert Component-Code in `app/components/ui/`
|
||||
- Prüft ob Component bereits existiert
|
||||
- Fragt bei Konflikten nach (überschreiben/skip)
|
||||
- Zeigt Success-Message mit Import-Beispiel
|
||||
|
||||
**`npx @memoro/ui list`**
|
||||
- Zeigt alle verfügbaren Components
|
||||
- Zeigt welche bereits in der App sind
|
||||
- Zeigt Beschreibung jedes Components
|
||||
|
||||
**`npx @memoro/ui update <component>`**
|
||||
- Updated einen existierenden Component
|
||||
- Zeigt Diff der Änderungen
|
||||
- Fragt nach Bestätigung
|
||||
|
||||
**`npx @memoro/ui diff <component>`**
|
||||
- Zeigt Unterschiede zwischen lokaler und Library-Version
|
||||
- Hilfreich um zu sehen ob lokale Anpassungen gemacht wurden
|
||||
|
||||
**Optional später:**
|
||||
- `init` - Erstellt `components/ui/` Ordner
|
||||
- `remove` - Entfernt Component aus App
|
||||
- `sync` - Updated alle Components auf einmal
|
||||
|
||||
### 3. Component Development Workflow
|
||||
|
||||
**Neuer Component:**
|
||||
1. Entwickle Component in `ui-components/components/`
|
||||
2. Teste in Preview-App
|
||||
3. Schreibe README mit Usage-Beispielen
|
||||
4. Update `registry.json`
|
||||
5. Commit & Push
|
||||
|
||||
**Component nutzen:**
|
||||
1. In App: `npx @memoro/ui add button`
|
||||
2. Component liegt jetzt in `app/components/ui/Button.tsx`
|
||||
3. Importieren: `import { Button } from '@/components/ui/Button'`
|
||||
4. Bei Bedarf app-spezifisch anpassen
|
||||
|
||||
**Component updaten:**
|
||||
1. Änderungen in Library-Repo
|
||||
2. Apps können entscheiden ob sie updaten wollen
|
||||
3. `npx @memoro/ui update button` in jeweiliger App
|
||||
4. Review des Diffs, dann accept/reject
|
||||
|
||||
### 4. Component Standards
|
||||
|
||||
**Jeder Component sollte haben:**
|
||||
|
||||
**Consistent API:**
|
||||
- Props sind konsistent benannt über alle Components
|
||||
- `variant`, `size`, `disabled` patterns
|
||||
- `className` für custom Tailwind classes
|
||||
- `children` wo sinnvoll
|
||||
|
||||
**TypeScript:**
|
||||
- Vollständige Type definitions
|
||||
- Exported Types für Props
|
||||
- Generic Support wo nötig
|
||||
|
||||
**Accessibility:**
|
||||
- ARIA labels wo nötig
|
||||
- Keyboard navigation
|
||||
- Screen reader support
|
||||
|
||||
**Styling:**
|
||||
- NativeWind/Tailwind classes
|
||||
- Responsive by default
|
||||
- Dark mode ready (später)
|
||||
|
||||
**Documentation:**
|
||||
- README.md mit:
|
||||
- Beschreibung
|
||||
- Props table
|
||||
- Usage examples
|
||||
- Variants showcase
|
||||
|
||||
### 5. Preview/Development App
|
||||
|
||||
**Expo App in ui-components/preview:**
|
||||
- Live preview aller Components
|
||||
- Test auf echten Devices
|
||||
- QR-Code für schnelles Testen
|
||||
- Optional: Storybook integration
|
||||
|
||||
**Zweck:**
|
||||
- Entwickle Components in Isolation
|
||||
- Visual testing
|
||||
- Dokumentation als Live-Demo
|
||||
- Teilen mit Designern für Feedback
|
||||
|
||||
### 6. Initial Component Set
|
||||
|
||||
**Start mit diesen Core Components:**
|
||||
|
||||
**UI Components (`packages/components/ui/`):**
|
||||
|
||||
**Layout:**
|
||||
- Container
|
||||
- Stack (VStack/HStack)
|
||||
- Spacer
|
||||
- Divider
|
||||
|
||||
**Input:**
|
||||
- Button
|
||||
- Input (TextInput)
|
||||
- Checkbox
|
||||
- Switch
|
||||
- Slider
|
||||
|
||||
**Display:**
|
||||
- Text (mit Typography variants)
|
||||
- Card
|
||||
- Badge
|
||||
- Avatar
|
||||
- Image (mit Loading states)
|
||||
|
||||
**Feedback:**
|
||||
- Alert
|
||||
- Toast
|
||||
- Spinner/Loading
|
||||
- Progress
|
||||
|
||||
**Overlay:**
|
||||
- Modal
|
||||
- Sheet (Bottom sheet)
|
||||
- Dropdown
|
||||
|
||||
**Navigation Components (`packages/components/navigation/`):**
|
||||
- Header (mit Title, Back Button, Actions)
|
||||
- TabBar (Bottom Tab Navigation)
|
||||
- BackButton
|
||||
- TabBarItem
|
||||
- HeaderAction (z.B. Settings Icon)
|
||||
|
||||
### 7. Naming Conventions
|
||||
|
||||
**Component Files:**
|
||||
- PascalCase: `Button.tsx`, `TextInput.tsx`
|
||||
- Co-located files: `Button.stories.tsx`, `Button.test.tsx`
|
||||
|
||||
**Registry IDs:**
|
||||
- kebab-case: `button`, `text-input`
|
||||
- Matches CLI usage: `npx ui add text-input`
|
||||
|
||||
**Variants:**
|
||||
- lowercase: `primary`, `secondary`, `outline`
|
||||
- Sizes: `sm`, `md`, `lg`, `xl`
|
||||
|
||||
### 8. Version Strategy (später relevant)
|
||||
|
||||
**Phase 1 (jetzt):**
|
||||
- Keine Versionierung nötig
|
||||
- Components werden kopiert = keine Breaking changes
|
||||
- Apps besitzen den Code
|
||||
|
||||
**Phase 2 (wenn nötig):**
|
||||
- Semantic versioning für CLI-Tool
|
||||
- Component changelog in README
|
||||
- Breaking changes werden dokumentiert
|
||||
- Apps updaten optional
|
||||
|
||||
### 9. Testing Strategy
|
||||
|
||||
**CLI-Tool:**
|
||||
- Unit tests für file operations
|
||||
- Integration tests für add/update commands
|
||||
- Test mit dummy Expo app
|
||||
|
||||
**Components:**
|
||||
- Visual testing in Preview app
|
||||
- Optional: Jest + React Native Testing Library
|
||||
- Manual testing auf iOS/Android
|
||||
|
||||
### 10. Migration Path für bestehende Apps
|
||||
|
||||
**Für "picture" App (erste Migration):**
|
||||
|
||||
1. **Setup:**
|
||||
- Setup `.npmrc` für GitHub Packages auth
|
||||
- `npm login --registry=https://npm.pkg.github.com`
|
||||
- Oder lokal ohne Installation: `npx @memoro/ui`
|
||||
|
||||
2. **Identify Components:**
|
||||
- Analysiere welche Components bereits in der App sind
|
||||
- Vergleiche mit Library - was kann ersetzt werden?
|
||||
|
||||
3. **Migrate Component by Component:**
|
||||
- Start mit einem simplen (z.B. Button)
|
||||
- `npx @memoro/ui add button`
|
||||
- Ersetze alte Implementierung
|
||||
- Teste gründlich
|
||||
- Repeat für weitere Components
|
||||
|
||||
4. **Custom Components:**
|
||||
- Wenn app-spezifisch: behalten in `app/components/`
|
||||
- Wenn wiederverwendbar: zu Library hinzufügen
|
||||
|
||||
**Für neue Apps:**
|
||||
- Start projekt
|
||||
- Setup `.npmrc` mit `@memoro:registry=https://npm.pkg.github.com`
|
||||
- `npx @memoro/ui init` (erstellt structure)
|
||||
- Add benötigte Components
|
||||
- Build feature
|
||||
|
||||
### 11. Documentation

|
||||
- Mini NPM package: `@memoro/tailwind-preset`
|
||||
- Ebenfalls via GitHub Packages publiziert
|
||||
- Components nutzen Design tokens
|
||||
- Zentrale Design updates möglich

|
||||
|
||||
## Decisions Made
|
||||
|
||||
### 1. Package Naming ✅
|
||||
**Entscheidung:** `@memoro/ui`
|
||||
|
||||
**Reasoning:**
|
||||
- Klarer, einprägsamer Name
|
||||
- Namespace `@memoro` für alle zukünftigen Packages
|
||||
- Konsistent für späteres `@memoro/tailwind-preset`
|
||||
|
||||
### 2. Registry ✅
|
||||
**Entscheidung:** GitHub Packages
|
||||
|
||||
**Reasoning:**
|
||||
- ✅ Kostenlos für private Repos
|
||||
- ✅ Bereits in GitHub - keine extra Infrastruktur
|
||||
- ✅ Einfache CI/CD Integration mit GitHub Actions
|
||||
- ✅ Ausreichend für 10+ Apps
|
||||
- ✅ Kann später zu Private NPM migriert werden wenn nötig
|
||||
|
||||
**Setup Details:**
|
||||
```json
|
||||
// package.json im CLI-Tool
|
||||
{
|
||||
"name": "@memoro/ui",
|
||||
"repository": "https://github.com/[username]/memoro-ui",
|
||||
"publishConfig": {
|
||||
"registry": "https://npm.pkg.github.com"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Usage in Apps:**
|
||||
```bash
|
||||
# .npmrc in jeder App
|
||||
@memoro:registry=https://npm.pkg.github.com
|
||||
|
||||
# Einmalig pro Developer:
|
||||
npm login --registry=https://npm.pkg.github.com
|
||||
|
||||
# Dann normal:
|
||||
npm install @memoro/ui
|
||||
npx @memoro/ui add button
|
||||
```
|
||||
|
||||
**GitHub Personal Access Token (PAT) benötigt mit:**
|
||||
- `read:packages` - Um Packages zu installieren
|
||||
- `write:packages` - Um zu publizieren (nur für Maintainer)
|
||||
|
||||
**CI/CD Setup (GitHub Actions):**
|
||||
```yaml
|
||||
- name: Setup NPM for GitHub Packages
|
||||
run: |
|
||||
echo "@memoro:registry=https://npm.pkg.github.com" >> .npmrc
|
||||
echo "//npm.pkg.github.com/:_authToken=${{ secrets.GITHUB_TOKEN }}" >> .npmrc
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 3. Component Scope ✅
|
||||
**Entscheidung:** UI-Components + Navigation Components
|
||||
|
||||
**Included:**
|
||||
- ✅ UI-Components (Button, Input, Card, Badge, Avatar, etc.)
|
||||
- ✅ Navigation Components (Header, TabBar, BackButton, etc.)
|
||||
|
||||
**Excluded (für jetzt):**
|
||||
- ❌ Form validation helpers
|
||||
- ❌ Data display (Lists, Tables, Pagination)
|
||||
- ❌ Complex business logic components
|
||||
|
||||
**Reasoning:**
|
||||
- Navigation components sind essentiell für jede App
|
||||
- Wiederholen sich über alle Apps hinweg
|
||||
- Bleiben UI-fokussiert ohne Business-Logik
|
||||
- Können später erweitert werden wenn Bedarf entsteht
|
||||
|
||||
### 4. Testing Strategy ✅
|
||||
**Entscheidung:** Manual Testing in Phase 1
|
||||
|
||||
**Phase 1:**
|
||||
- Manual testing in Preview App
|
||||
- Visual verification auf iOS/Android
|
||||
- Component usage testing in real apps
|
||||
|
||||
**Phase 2 (später):**
|
||||
- Automated tests wenn Library >5 Components hat
|
||||
- Jest + React Native Testing Library
|
||||
- Visual regression testing (optional)
|
||||
|
||||
**Reasoning:**
|
||||
- Schneller Start ohne Testing-Overhead
|
||||
- Preview App bietet gute visuelle Kontrolle
|
||||
- Automated tests später wenn Library stabiler ist
|
||||
|
||||
### 5. Preview App ✅
|
||||
**Entscheidung:** Lokale Expo App
|
||||
|
||||
**Setup:**
|
||||
- Expo App im Monorepo unter `packages/preview/`
|
||||
- Dev Client für native Features
|
||||
- Hot reload während Component-Development
|
||||
|
||||
**Reasoning:**
|
||||
- ✅ Mehr Kontrolle als Expo Snack
|
||||
- ✅ Native Features testbar (z.B. Haptics, Gestures)
|
||||
- ✅ Läuft im gleichen Repo - einfaches Development
|
||||
- ✅ Kann mit Components in `packages/components/` direkt arbeiten
|
||||
|
||||
### 6. Repository Structure ✅
|
||||
**Entscheidung:** Monorepo mit pnpm workspaces
|
||||
|
||||
**Structure:**
|
||||
```
|
||||
memoro-ui/
|
||||
├── packages/
|
||||
│ ├── cli/ # @memoro/ui CLI-Tool
|
||||
│ │ ├── src/
|
||||
│ │ ├── package.json
|
||||
│ │ └── README.md
|
||||
│ ├── components/ # Component source code
|
||||
│ │ ├── Button/
|
||||
│ │ ├── Input/
|
||||
│ │ └── ...
|
||||
│ └── preview/ # Expo preview app
|
||||
│ ├── app/
|
||||
│ ├── package.json
|
||||
│ └── README.md
|
||||
├── registry.json # Component metadata
|
||||
├── pnpm-workspace.yaml
|
||||
├── package.json
|
||||
└── README.md
|
||||
```
|
||||
|
||||
**pnpm-workspace.yaml:**
|
||||
```yaml
|
||||
packages:
|
||||
- 'packages/*'
|
||||
```
|
||||
|
||||
**Reasoning:**
|
||||
- ✅ Alles in einem Repo - einfacher zu entwickeln
|
||||
- ✅ Shared dependencies zwischen Packages
|
||||
- ✅ pnpm = schneller & effizienter als npm/yarn
|
||||
- ✅ Preview App kann Components direkt importieren
|
||||
- ✅ CLI kann direkt auf Components zugreifen
|
||||
|
||||
### 7. GitHub Organization ✅
|
||||
**Entscheidung:** GitHub Organization `@memoro`
|
||||
|
||||
**Setup:**
|
||||
- Neue GitHub Org: `memoro` (oder `memoro-ui`)
|
||||
- Repo: `github.com/memoro/ui` (oder ähnlich)
|
||||
- Package: `@memoro/ui`
|
||||
|
||||
**Package Configuration:**
|
||||
```json
|
||||
{
|
||||
"name": "@memoro/ui",
|
||||
"repository": "https://github.com/memoro/ui",
|
||||
"publishConfig": {
|
||||
"registry": "https://npm.pkg.github.com"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Reasoning:**
|
||||
- ✅ Professioneller Auftritt
|
||||
- ✅ Namespace für zukünftige Packages (`@memoro/tailwind-preset`)
|
||||
- ✅ Einfacher Team-Management später
|
||||
- ✅ Klare Trennung von Personal Projects
|
||||
|
||||
**GitHub Org Setup:**
|
||||
1. Erstelle neue Org: https://github.com/organizations/plan
|
||||
2. Invite Members (wenn Team)
|
||||
3. Setup Package Permissions
|
||||
4. Create `ui` repository
|
||||
|
||||

|
||||
|
||||
## Open Questions / Decisions Needed
|
||||
|
||||
**Alle Haupt-Entscheidungen getroffen! ✅**
|
||||
|
||||
Optionale Entscheidungen für später:
|
||||
- **Icon System:** Eigenes Icon-Set oder bestehende Library? (@expo/vector-icons, react-native-heroicons)
|
||||
- **Animation Library:** Reanimated, Moti, oder custom?
|
||||
- **TypeScript Strictness:** Wie streng? (strict mode, exactOptionalPropertyTypes, etc.)

# Web Framework Comparison: Next.js vs SvelteKit
|
||||
|
||||
**Datum:** 2025-10-08
|
||||
**Kontext:** Evaluation für separate Web-Version der Picture App
|
||||
|
||||
## Executive Summary
|
||||
|
||||
Für eine Bilder-App mit gleichwertigen Mobile (React Native) und Web Anforderungen wird **Next.js 15** empfohlen, trotz geringerer Unabhängigkeit. Grund: Produktivität, Image Optimization und React-Synergien überwiegen die Nachteile.
|
||||
|
||||
---
|
||||
|
||||
## Tech Stack Unabhängigkeit
|
||||
|
||||
### **SvelteKit** ✅ Unabhängiger
|
||||
- **Compiler-basiert** - kompiliert zu Vanilla JS
|
||||
- Keine Runtime Framework (React, Vue, etc.)
|
||||
- Kleinere Abhängigkeiten
|
||||
- Weniger Vendor Lock-in
|
||||
- Zukunftssicherer durch Web Standards
|
||||
|
||||
### **Next.js** ⚠️ React-Ökosystem
|
||||
- Fest an React gebunden
|
||||
- Braucht React Ökosystem (React Query, etc.)
|
||||
- Größere Bundle Sizes
|
||||
- Meta/Vercel-abhängig
|
||||
|
||||
---
|
||||
|
||||
## Performance
|
||||
|
||||
### **SvelteKit** 🚀
|
||||
- **Extrem schnell** - kein Virtual DOM
|
||||
- Kleinere Bundles (20-30% weniger)
|
||||
- Schnelleres First Paint
|
||||
- Weniger JavaScript zum Browser
|
||||
- Beispiel: 50KB vs 150KB initial
|
||||
|
||||
### **Next.js** 👍
|
||||
- Gut, aber schwerer
|
||||
- Virtual DOM Overhead
|
||||
- Hydration kann langsam sein
|
||||
- Mehr JavaScript = langsamere Mobile Devices

||||
let count = 0; // Kein useState!
|
||||
</script>
|
||||
|
||||
<button on:click={() => count++}>
|

**UI Libraries:**
|
||||
- Skeleton UI
|
||||
- DaisyUI (Tailwind-based)
|
||||
- Carbon Components
|
||||
- Smelte
|
||||
- Weniger Auswahl
|
||||
|
||||
**Aber:**
|
||||
- Kann CSS Frameworks nutzen (Tailwind, UnoCSS)
|
||||
- Viele Web Components nutzbar
|
||||
|
||||
---
|
||||
|
||||
## Image Handling (kritisch für Picture App!)

|
||||
- `next/image` Component eingebaut
|
||||
- Automatische Optimierung
|
||||
- WebP/AVIF Konvertierung
|
||||
- Lazy Loading
|
||||
- Blur Placeholder
|
||||
- **Produktionsreif out of the box**
|
||||
|
||||
### **SvelteKit** ⚠️ Braucht Setup
|
||||
- Kein eingebautes Image Optimization
|
||||
- Manuell mit Vite Plugins (vite-imagetools)
|
||||
- Oder externe Services (Cloudinary, imgix)
|
||||
- Mehr Arbeit nötig
|
||||
|
||||
---
|
||||
|
||||

||||
|
||||
**Vercel:** Beide erste Klasse
|
||||
**Netlify:** Beide gut
|
||||
**Cloudflare Pages:** Beide möglich
|
||||
**Self-hosted:** Beide Node oder Adapter
|
||||
|
||||
### **Unterschiede:**

|
||||
- Läuft überall gleich gut
|
||||
|
||||
---
|
||||
|
||||
## Code Sharing mit React Native
|
||||
|
||||
### **Next.js** ✅ Einfacher
|
||||
- Beide nutzen React
|
||||
- Components **teilweise** portierbar
|
||||
- Gleiche Patterns (Hooks)
|
||||
- Logic besser teilbar
|
||||
|
||||
### **SvelteKit** ⚠️ Schwieriger
|
||||
- Komplett andere Syntax
|
||||
- Nur Business Logic teilbar
|
||||
- UI muss komplett neu
|
||||
|
||||
---
|
||||
|
||||
## Hiring & Team
|
||||
|
||||
### **Next.js** ✅
|
||||
- Jeder React Dev kann Next.js

|
||||
|
||||

|
||||
|
||||
## Empfehlung: Next.js 15 + Tailwind
|
||||
|
||||
### Begründung
|
||||
|
||||
1. **Image App** - Next.js Image Component ist Gold wert für eine Bilder-App
|
||||
2. **Produktivität** - Schneller zu produktionsreifem Code
|
||||
3. **React Native Synergien** - Gleiche Patterns, geteiltes Wissen
|
||||
4. **Community** - Jedes Problem bereits gelöst
|
||||
5. **Realismus** - Shipped > Perfect
|
||||
|
||||
### Strategie für Unabhängigkeit trotz Next.js
|
||||
|
||||
```
|
||||
/packages
|
||||
/shared # TypeScript Core Logic
|
||||
/types # Supabase Types, Shared Types
|
||||
/api # Supabase Client, API Calls
|
||||
/utils # Business Logic, Helpers
|
||||
|
||||
/mobile # React Native (existing)
|
||||
|
||||
/web # Next.js
|
||||
/app # App Router
|
||||
/components # Web-specific Components
|
||||
/lib # Web-specific Utils
|
||||
```
|
||||
|
||||
**Regeln:**
|
||||
1. ❌ **Keine Next.js spezifischen Features** außer Image und Routing
|
||||
2. ✅ **Business Logic in `/shared`** auslagern
|
||||
3. ✅ **Vercel-unabhängig deployen** (z.B. Cloudflare, Netlify)
|
||||
4. ✅ **TypeScript überall** - leichter migrierbar
|
||||
5. ✅ **Supabase als SST** - nicht an Next.js Backend gebunden
|
||||
|
||||
### Migrations-Pfad
|
||||
|
||||
Durch saubere Architektur bleibt Migration zu SvelteKit möglich:
|
||||
|
||||
```
|
||||
Phase 1: Next.js mit Shared Logic (jetzt)
|
||||
↓
|
||||
Phase 2: Optional - SvelteKit Parallel-Entwicklung (später)
|
||||
↓
|
||||
Phase 3: Optional - Migration zu SvelteKit wenn Next.js nervt
|
||||
```
|
||||
|
||||
**80% der Unabhängigkeit durch Architektur, 20% durch Framework.**
|
||||
|
||||
---
|
||||
|
||||
## Alternative: Expo Web Status
|
||||
|
||||
**Warum NICHT Expo Web?**
|
||||
|
||||
Die App nutzt viele native-only Features:
|
||||
- `react-native-worklets` (JSI/Native)
|
||||
- `react-native-reanimated` (Native Animations)
|
||||
- `react-native-pager-view` (Native Views)
|
||||
- `react-native-context-menu-view` (Native Menus)
|
||||
- Gesten, Zoom, Blur...
|
||||
|
||||
**Probleme:**
|
||||
- 2-5 Tage Debugging für Mocks
|
||||
- Ständige Workarounds
|
||||
- Limitierte Features
|
||||
- Schlechte Performance
|
||||
- Hohe Frustration
|
||||
|
||||
**Fazit:** Expo Web ist nicht für native-lastige Apps gedacht.
