🎨 Design Choices & Architecture

State Management

• React Context: Used for cart state management due to its simplicity and built-in React support
• TanStack Query: Implemented for server state management with caching, retries, and background updates

Component Architecture

• Functional Components: Modern React with hooks
• TypeScript: Full type safety for better development experience
• Responsive Design: Mobile-first approach with Tailwind CSS

Data Fetching Strategy

• TanStack Query: Provides caching, background updates, and error handling
• Optimistic Updates: Cart updates are immediate for better UX
• Error Boundaries: Graceful error handling with retry mechanisms

Performance Optimizations

• Image Optimization: Next.js Image component with proper sizing
• Code Splitting: Automatic with Next.js App Router
• Caching: TanStack Query provides intelligent caching
• Lazy Loading: Images and components load as needed
