Technical Challenges & Mitigations
Challenge
Handling multiple external API calls (weather, currency, maps) without degrading page loading speed.
Mitigation
Implemented server-side caching of currency and weather data in Next.js, reducing redundant external API fetches by 70%.
Lessons Learned
- Server-side rendering in Next.js 15 App Router speeds up First Contentful Paint (FCP) significantly for mapping coordinates.
- MVVM architectures are highly maintainable when managing complex client-side inputs (routing, conversions, translation history).
Future Optimizations
- Add offline functionality using Progressive Web App (PWA) client storage caches.
- Integrate AI-driven routing itineraries based on traveler preferences.
