PostgreSQL has an 8KB index size limit. Base64 images (even after compression)
easily exceed this limit, causing errors like:
"index row requires 2141448 bytes, maximum size is 8191"
Solution:
- Dropped idx_users_photo_url index from users table
- Updated V008 migration to not create the index
- Added comment explaining why no index is needed
The photo_url column is rarely queried directly, so a full table scan
when needed is acceptable. Photos are typically loaded via user_id lookups.

Added express body parser configuration to support base64 image uploads:
- Set JSON payload limit to 10MB (up from default 100kb)
- Set URL-encoded payload limit to 10MB
- This allows users to upload profile photos and child photos via base64 encoding
Without this fix, uploading photos would result in 500 Internal Server Error due to payload too large.

Added complete photo upload support for user profiles:
- Added photoUrl field to User entity and all auth responses
- Created migration V008 for photo_url column in users table
- Updated UpdateProfileDto to include photoUrl validation
- Modified auth.service.ts to handle photoUrl in all user responses (register, login, getUserById, updateProfile, refreshAccessToken, loginWithExternalAuth)
- Updated AuthResponse interface to include photoUrl
- Updated frontend User and UserProfile interfaces to include photoUrl
- Updated AppShell to display user photoUrl in header avatar
- Fixed ChildDialog to remove invalid props from PhotoUpload component
The photo upload uses base64 encoding (max 5MB) for simplicity and works across all environments. Future enhancement can migrate to CDN/object storage.

The MinIO/Sharp approach doesn't work on the current server CPU architecture.
Switched to simple base64 encoding for photo uploads.
Changes:
- PhotoUpload component converts images to base64 data URLs
- 5MB file size limit
- Works on all platforms without external dependencies
- Stores photos directly in database (photoUrl field)
This is a temporary solution. For production scalability, we can:
- Upgrade server CPU to support Sharp
- Build Sharp from source
- Use Docker with prebuilt Sharp binaries
- Migrate to a proper CDN/object storage later

The server CPU doesn't support Sharp's prebuilt binaries (requires v2 microarchitecture).
Added graceful fallback to upload images without optimization when Sharp is unavailable.
Changes:
- StorageService.uploadImage() falls back to direct upload without optimization
- StorageService.generateThumbnail() uses original image if Sharp fails
- Logs warnings when Sharp is unavailable instead of crashing
- Photo uploads now work on all CPU architectures
Images upload without optimization until Sharp is built from source or server is upgraded.

The photos upload endpoint was missing authentication, causing 500 errors.
Added @UseGuards(JwtAuthGuard) to protect all photo endpoints and ensure
req.user is populated for photo operations.
Fixes photo upload authentication issue.

Voice classification extracts duration in minutes, but sleep tracker expects
startTime/endTime. Added transformation logic to convert duration to proper
time range for sleep activities.
- Convert duration (minutes) to startTime + endTime timestamps
- Set default quality='good' and location='crib' if not specified
- Remove duration field after transformation

Create detailed implementation plan for securing backend API while supporting
web, mobile apps, WebSockets, and GraphQL.
## Current State Analysis
- Backend API fully exposed to internet (security risk)
- Direct API calls from browser
- No infrastructure-level rate limiting
- Future mobile apps need direct access
- WebSocket + GraphQL endpoints require special handling
## Proposed Solutions
### Phase 1: MVP - Next.js BFF Pattern (1-2 weeks)
- Next.js API routes as proxy for web app
- Direct backend access for mobile (with API keys)
- Internal API key authentication
- WebSocket remains direct (Next.js limitation)
### Phase 2: Production - Kong Gateway (4-6 weeks post-MVP)
- Centralized API gateway for all clients
- Backend becomes fully internal
- Advanced features: caching, monitoring, GraphQL federation
## Implementation Details
**Files to Create**:
- app/api/proxy/[...path]/route.ts - Generic REST proxy
- app/api/graphql/route.ts - GraphQL proxy
- src/common/guards/internal-api-key.guard.ts - Backend auth
**Security Features**:
- Internal API key for BFF → Backend communication
- Mobile API key for mobile → Backend
- Rate limiting: 100 req/min (web), 60 req/min (mobile)
- Strict CORS configuration
- Nginx reverse proxy with SSL termination
**Architecture Diagrams**:
- BFF pattern with Next.js (recommended for MVP)
- Kong Gateway pattern (production-ready)
- Mobile app integration strategy
**Includes**:
- Step-by-step implementation plan
- Code samples for all components
- Nginx configuration
- Environment variable setup
- Security enhancements
- Performance considerations (+20-40ms latency)
- Monitoring and logging
- Troubleshooting guide
- Deployment timeline
Addresses security concerns while maintaining support for:
✅ Web app (through BFF)
✅ Mobile apps (direct with API key)
✅ Real-time WebSocket
✅ GraphQL queries and subscriptions
