Implemented comprehensive frontend localization infrastructure supporting
5 languages (English, Spanish, French, Portuguese, Chinese) with measurement
unit preferences (Metric/Imperial). This lays the foundation for international
user support.
**Core Infrastructure:**
- Installed i18next, react-i18next, i18next-browser-languagedetector
- Created I18nProvider component integrated into app layout
- Configured i18next with language detection and localStorage persistence
- Created 35 translation files (5 languages × 7 namespaces)
**Translation Namespaces:**
- common: App-wide UI elements, navigation, actions
- tracking: Activity tracking (feeding, sleep, diaper, milestones)
- ai: AI assistant chat interface
- auth: Authentication flows (login, signup, password reset)
- settings: Settings and preferences
- onboarding: Onboarding flow
- errors: Error messages and validation
**Custom Hooks:**
- useTranslation: Type-safe translation wrapper
- useLocale: Language and measurement system management
- useFormatting: Date, time, number, and unit formatting
**Measurement Unit Support:**
- Created unit conversion utilities (weight, height, temperature, volume)
- Metric: kg, cm, °C, ml
- Imperial: lb, in, °F, oz
- Bidirectional conversion functions
**UI Components:**
- LanguageSelector: Dropdown to change app language
- MeasurementUnitSelector: Toggle between Metric/Imperial
- Integrated both into Settings page Preferences section
**Next Steps (Remaining):**
- Add measurement preferences to backend user schema
- Create onboarding flow with language/measurement selection
- Apply translations to existing components (dashboard, tracking forms)
- Implement multi-language AI responses
- Add professional translations (currently using basic translations)
**File Highlights:**
- lib/i18n/config.ts: i18next configuration
- hooks/useFormatting.ts: Formatting utilities with locale support
- lib/utils/unitConversion.ts: Unit conversion logic
- components/settings/*Selector.tsx: Language and measurement selectors
- locales/*/: Translation files for 5 languages

Add complete GraphQL mutation support for activity tracking and child management:
**Activity Mutations:**
- createActivity: Create new activities (feeding, sleep, diaper, medication)
- updateActivity: Update existing activities
- deleteActivity: Delete activities
**Child Mutations:**
- createChild: Add new children to families
- updateChild: Update child information
- deleteChild: Soft delete children
**Implementation Details:**
- Created GraphQL input types (CreateActivityInput, UpdateActivityInput, CreateChildInput, UpdateChildInput)
- Implemented ActivityResolver with full CRUD mutations
- Implemented ChildResolver with full CRUD mutations
- Registered resolvers in GraphQL module with TrackingService and ChildrenService
- Auto-generated GraphQL schema with all mutations
- All mutations protected with GqlAuthGuard for authentication
- Support for JSON metadata fields and Gender enum

Added Redux Provider to app layout and simplified Redux store to work
properly with Next.js SSR.
**Changes:**
- Added ReduxProvider wrapper to root layout (app/layout.tsx)
- Fixed ReduxProvider TypeScript type (React.ReactNode)
- Simplified store configuration by removing @redux-offline package
- Removed packages incompatible with SSR:
- @redux-offline/redux-offline
- redux-persist
- localforage
- Re-added NetworkStatusIndicator to main page (now works with Redux)
- Kept custom offline middleware and sync middleware for offline-first functionality
**Why:**
The @redux-offline package and localforage try to access browser APIs (IndexedDB,
localStorage) during SSR, causing "No available storage method found" errors.
Our custom offline middleware provides the same functionality without SSR issues.
**Result:**
Redux store now works correctly with:
- Network status detection
- Offline action queuing
- Custom sync middleware
- Activities and children slices with optimistic updates
Next step: Can add redux-persist back with proper SSR guards if needed.

Implemented React error boundaries to catch and handle errors gracefully:
**Core Error Handling Components:**
- Created ErrorBoundary class component with error catching and logging
- Created specialized fallback UIs (MinimalErrorFallback, DataErrorFallback,
ComponentErrorFallback, FormErrorFallback, ChartErrorFallback, ImageErrorFallback)
- Added withErrorBoundary HOC for easy component wrapping
- Created errorLogger service with Sentry integration placeholder
**Error Logging Service (errorLogger.ts):**
- Centralized error logging with severity levels (FATAL, ERROR, WARNING, INFO, DEBUG)
- Context enrichment (URL, userAgent, timestamp, environment)
- Local storage of last 10 errors in sessionStorage for debugging
- User context management (setUser, clearUser)
- Breadcrumb support for debugging trails
**App Integration:**
- Wrapped root layout with top-level ErrorBoundary for catastrophic errors
- Added NetworkStatusIndicator to main page for offline sync visibility
- Wrapped daily summary section with isolated DataErrorFallback
- Added error boundary to AI assistant page with ComponentErrorFallback
- Wrapped feeding tracking form with FormErrorFallback using withErrorBoundary HOC
- Protected analytics charts with isolated ChartErrorFallback boundaries
**Error Recovery Features:**
- Isolated error boundaries prevent cascade failures
- Retry buttons on all fallback UIs
- Error count tracking with user warnings
- Development-mode error details display
- Automatic error logging to service (when Sentry integrated)
Next: Integration with Sentry for production error tracking
