Kelowna Islamic Center Application Architecture

The KIC ecosystem is built as a modular, event-driven system with the following key characteristics:

  • Serverless backend powered by Firebase Cloud Functions, handling notifications, prayer times, and announcements.
  • Real-time synchronization of announcements via Firestore, ensuring all client apps stay automatically up to date.
  • Cross-platform frontends:
    • Flutter Mobile App for community members (Android/iOS)
    • Web Kiosk App for Masjid display screens

High-Level Components

Firebase Cloud Functions (Server-Side)

Cloud Functions serve as the backend layer, managing all server-side logic. They interact with Firestore, Firebase Cloud Messaging (FCM), and external APIs (such as BCMA and Islamic Finder), providing clean and easily controlable data for the clients.

Clients (Mobile App, Kiosk App)

The clients are the user-facing applications: the mobile app and the kiosk app. Both connect exclusively through Firebase services such as Cloud Functions, Firestore, and FCM, keeping the front-end architecture lightweight and maintainable.
