🏗 Architecture

MVVM Pattern

┌─ View Layer (Fragments)
│   └─ Observe LiveData
│       └─ Triggers UI updates
│
├─ ViewModel Layer
│   └─ Manages UI state
│       └─ Handles user interactions
│
└─ Data Layer (Repositories)
    └─ Provides data from Local/Remote
        └─ Room DB + Firestore

Clean Architecture Principles

Presentation Layer (UI, ViewModels)
        ↓
Domain Layer (Business Models)
        ↓
Data Layer (Repositories)
        ↓
Data Sources (Local DB, Remote API)

Repository Pattern

  • Single Source of Truth for data
  • Abstraction between layers
  • Smart Caching with Room
  • Conflict Resolution between local & remote

Dependency Injection (Hilt)

// Automatic injection of dependencies
@Inject
ProductRepository productRepository;

// Provides singletons for Firebase, DB, etc.
@Provides
@Singleton
FirebaseAuth provideAuth() { ... }
