Trip Offline

TripOffline

Technologies: Quasar (Vue 3), Pinia, Leaflet, IndexedDB, Capacitor, PWA, TTS API

TripOffline is a comprehensive city guide application developed specifically for Poland (Warsaw) that can operate without an internet connection. Built on the Quasar and Capacitor architecture, the project delivers a seamless user experience across Web, PWA, and Native Mobile platforms.

• Offline Map Technology: Offline management of map data is achieved through Leaflet integration and a custom tile caching system based on IndexedDB.
• Touristic Data Management: Advanced filtering and detailed views for touristic locations and Wi-Fi hotspots were implemented using static datasets structured within Pinia stores.
• Language and Accessibility: i18n support for 9 languages, RTL (Arabic) compatibility, and Text-to-Speech (TTS) integration for basic Polish phrases were implemented.
• PWA and Native Integration: Advanced Service Worker configuration using Workbox and optimized native geolocation permissions via Capacitor.

In this project, efficient usage of large-scale map data was achieved within browser and device storage limits, and a multi-platform (Web/Mobile) guide solution was built using a single codebase.
