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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
