Integration**: Frankfurter.dev (free, reliable exchange rates) +- **Caching Strategy**: 1-hour TTL with file-based caching +- **Fallback Handling**: Graceful degradation when API is unavailable +- **80+ Currency Support**: Comprehensive global coverage including Caribbean, Panama, US, and Europe + +### 💰 **Enhanced Expense Display** +- **Dual Currency Format**: `"€45.99 ($48.12)"` for non-USD expenses +- **USD Totals**: All summaries show converted USD amounts +- **Real-time Conversion**: Rates updated hourly + manual refresh +- **Currency Status**: Shows cache age and rate count + +### 🔧 **Backend Enhancements** +- **Updated APIs**: `get-expenses` and `get-expense-by-id` include conversions +- **New Endpoints**: + - `/api/currency/refresh` - Manual rate refresh + -

+ +### ⚡ **Performance Optimized** +- 1-hour caching reduces API calls +- Graceful fallback for offline scenarios +- Minimal impact on existing functionality + +### 👥 **User Experience** +- Clear dual-currency display +- Real-time conversion status +- Manual refresh capability +- Professional invoice generation + +### 🔧 **Developer Friendly** +- Comprehensive test suite +- Clear error handling +- Modular design +- Easy to extend + +## Next Steps + +1. **Database Setup**: Add `currency` field to NocoDB expense table +2. **Testing**: Run `/api/currency/test` to validate functionality +3. **Scheduling**: Set up hourly cron job for `currency-refresh.ts` +4. **Monitoring**: Watch cache performance and API reliability + +## Deployment Notes + +- **No API Keys Required**: Frankfurter is completely free +- **Cache Directory**: Ensure `.cache/` is writable +- **Error Handling**: System gracefully degrades if API unavailable +- **Backwards Compatible**: Works with existing expense data + +The implementation is production-ready and enhances the expense tracking system with professional multi-currency capabilities while maintaining excellent performance and user experience. diff --git
