What to build

Build a React component to register public/sw.js and provide a non-intrusive offline status banner in the top command bar when the field device disconnects from the Internet.

Technical specifications

  1. Target files:
    • src/components/pwa/service-worker-register.tsx: Client component managing navigator.serviceWorker.
    • src/components/controls/offline-indicator-banner.tsx: Visual offline status chip (Offline: Data Tersimpan di Perangkat).
    • src/app/layout.tsx: Mount ServiceWorkerRegister.

Acceptance criteria

  • Registers service worker on browser mount.
  • Detects window.addEventListener('offline') and surfaces status chip.
  • Clicking the chip reveals cached coverage summary.

Blocked by

  • Issue 28: [Backend] Offline range-request Service Worker caching engine (public/sw.js).

⚠️ Reopened during deep code audit: ServiceWorker registration exists in src/components/pwa/service-worker-register.tsx, but the non-intrusive offline status banner/indicator in the top command bar has not yet been implemented.
