🏗 Architecture

State Management

The app uses Zustand for global state management and React Query for server state:

• Zustand: Manages user authentication, favorites, and app preferences
• React Query: Handles API data fetching, caching, and synchronization

Data Flow

1. API Layer: Centralized API client in services/api.ts
2. Custom Hooks: Business logic encapsulated in custom hooks
3. Components: UI components consume data through hooks
4. Local Storage: Persistent data stored using AsyncStorage

Navigation

• Expo Router: File-based routing system
• Tab Navigation: Main app sections (Home, Browse, Favorites, Settings)
• Stack Navigation: Product details and authentication flows

🎨 UI/UX Design

Design System

• Typography: Consistent text hierarchy and spacing
• Colors: Dynamic theming with vendor-specific primary colors
• Components: Reusable, accessible UI components
• Animations: Smooth transitions and micro-interactions

Accessibility

• Screen Reader Support: Proper accessibility labels
• Color Contrast: WCAG compliant color combinations
• Touch Targets: Adequate touch target sizes
• Keyboard Navigation: Full keyboard accessibility

🔒 Security

• Authentication: Secure user authentication flow
• Data Validation: Input validation and sanitization
• API Security: Secure API communication
• Local Storage: Encrypted sensitive data storage

🧪 Testing
