5️⃣ NEXT.JS IMAGE CONFIGURATION
|
||||
════════════════════════════════════════════════════════════════════════════
|
||||
|
||||
File: apps/web/next.config.js
|
||||
|
||||
Configuration:
|
||||
images: {
|
||||
remotePatterns: [
|
||||
{
|
||||
protocol: 'https',
|
||||
hostname: '**',
|
||||
},
|
||||
],
|
||||
}
|
||||
|
||||
Analysis:
|
||||
✅ Permissive remotePatterns allows all HTTPS domains
|
||||
✅ Protocol restricted to HTTPS (security)
|
||||
✅ Sensible for multi-source property platform
|
||||
⚠️ Wildcard hostname - ensure API validates image URLs
|
||||
|
||||
CSP Headers (lines 34-47):
|
||||
img-src 'self' data: blob: https://*.mapbox.com https://*.tiles.mapbox.com https:
|
||||
|
||||
Analysis:
|
||||
✅ Allows blob: URLs (file upload preview)
|
||||
✅ Allows data: URLs (inline base64)
|
||||
✅ Allows self-hosted images
|
||||
✅ Allows Mapbox tiles
|
||||
✅ Allows all HTTPS sources
|
||||
|
||||
|
||||
6️⃣ IMAGE UTILITIES & HELPERS
|
||||
════════════════════════════════════════════════════════════════════════════
|
||||
|
||||
No Dedicated Image Utility Libraries Found
|
||||
|
||||
Inline Utilities:
|
||||
In image-upload.tsx:
|
||||
✓ URL.createObjectURL() for blob preview (line 36)
|
||||
✓ URL.revokeObjectURL() for cleanup (lines 50, 80)
|
||||
|
||||
In image-lightbox.tsx:
|
||||
✓ useSwipe() hook (lines 19-52) - touch gestures
|
||||
✓ useFocusTrap() hook (lines 56-99) - accessibility
|
||||
✓ Image preloading with new window.Image() (line 185)
|
||||
|
||||
|
||||
7️⃣ ACCESSIBILITY & PERFORMANCE
|
||||
════════════════════════════════════════════════════════════════════════════
|
||||
|
||||
Accessibility Features:
|
||||
✅ Alt text on all images
|
||||
✅ Vietnamese localization
|
||||
✅ ARIA labels for galleries
|
||||
✅ Keyboard navigation (Arrow keys, Escape)
|
||||
✅ Focus trap in modal
|
||||
✅ Tab trapping for accessibility
|
||||
|
||||
Performance Optimizations:
|
||||
✅ priority prop for above-fold images
|
||||
✅ sizes prop for responsive images
|
||||
✅ fill + sizes for gallery
|
||||
✅ Image preloading in lightbox
|
||||
✅ Blob URL cleanup on unmount
|
||||
✅ Object URL revocation (prevent memory leaks)
|
||||
|
||||
Potential Improvements:
|
||||
⚠️ Add skeleton/blur placeholders during load
|
||||
⚠️ Implement image compression before upload
|
||||
⚠️ Add image resize optimization on upload
|
||||
|
||||
|
||||
8️⃣ SECURITY OBSERVATIONS
|
||||
════════════════════════════════════════════════════════════════════════════
|
||||
|
||||
Secure Practices:
|
||||
✅ Remote patterns restricted to HTTPS only
|
||||
✅ CSP headers properly configured
|
||||
✅ blob: URLs only for temporary client-side previews
|
||||
✅ No inline image data in components
|
||||
|
||||
Points to Monitor:
|
||||
⚠️ Validate image URLs at API layer
|
||||
⚠️ Scan user-uploaded images for malware
|
||||
⚠️ Consider CDN integration for scaling
|
||||
|
||||
|
||||
9️⃣ RECOMMENDATIONS
|
||||
════════════════════════════════════════════════════════════════════════════
|
||||
|
||||
Priority 1 (Implement Soon):
|
||||
1. Add image URL validation at API layer
|
||||
2. Implement image scanning for user uploads
|
||||
3. Consider CDN integration
|
||||
|
||||
Priority 2 (Nice to Have):
|
||||
1. Add skeleton/blur placeholders
|
||||
2. Implement image compression before upload
|
||||
3. Add image resize worker on upload
|
||||
|
||||
Priority 3 (Future):
|
||||
1. Implement image caching strategy
|
||||
2. Progressive image loading (LQIP)
|
||||
3. EXIF data removal for privacy
