Features

Product Catalog Management

• Implementation: Admin UI for CRUD operations on products and inventory, stored in MongoDB.
• Challenge: Ensuring real-time updates and validation.
• Solution: Used Mongoose for schema validation and Zustand for state management.

Shopping Cart

• Implementation: Persistent cart using Zustand and localStorage; supports add, remove, and update.
• Challenge: Cart state consistency across sessions.
• Solution: Zustand middleware for state persistence.

Payment Gateway Integration

• Implementation: Stripe/PayPal integration (test mode) for secure payments and order confirmation.
• Challenge: Handling errors and concurrency.
• Solution: Robust error handling and user feedback via toasts.

Order Processing

• Implementation: Orders stored in MongoDB with detailed info; admin dashboard for management.
• Challenge: Atomic order creation and inventory updates.
• Solution: Server-side validation and API endpoints.

3D Virtual Showroom

• Implementation: Three.js and React Three Fiber for interactive 3D product viewing.
• Challenge: Web performance.
• Solution: Lazy loading and dynamic imports for 3D assets.

Implementation Details

Architecture

• Frontend: Modular React components; Next.js pages/hooks for business logic.
• Backend: Next.js API routes for /api/products, /api/orders, /api/auth, etc.
• Database: MongoDB collections for users, products, orders, and categories (via Mongoose).

Example API Endpoint:

// app/api/products/route.ts
export async function GET() {
  try {
    // Fetch products from DB
    return NextResponse.json(await Product.find({}))
  } catch (error) {
    return NextResponse.json({ error: "Failed to fetch products" }, { status: 500 })
  }
}

Design Patterns:

• Container/Presentational component split
• Atomic design for UI components
• Middleware for authentication and error handling

Code Examples

Cart Management with Zustand:

import create from 'zustand';

export const useCart = create((set) => ({
  cart: [],
  addToCart: (item) => set((state) => ({ cart: [...state.cart, item] })),
  removeFromCart: (id) => set((state) => ({ cart: state.cart.filter(i => i.id !== id) })),
  clearCart: () => set({ cart: [] }),
}));

MongoDB Product Schema:

const ProductSchema = new mongoose.Schema({
  name: { type: String, required: true },
  price: { type: Number, required: true },
  description: String,
  image: String,
  category: String,
  stock: Number,
});

---

Challenges and Solutions

• Real-time cart updates: Zustand and localStorage sync for persistence.
• Secure authentication: NextAuth.js with JWT and server-side role checks.
• 3D rendering: Code splitting, dynamic imports, optimized 3D models.
• Order validation: Atomic backend operations and UI loading states.

---

Testing and Quality Assurance

• Strategies:
  • Unit tests for utilities and business logic
  • Integration tests for API endpoints (Jest + Supertest)
  • UI tests with React Testing Library and Cypress
  • Manual end-to-end testing for shopping, payment, and admin flows
• Tools: Jest, React Testing Library, ESLint, Prettier

---

Deployment

• Platform: Vercel
• Setup:
  1. Fork/clone the repository
  2. Create a .env file with MongoDB URI, Stripe/PayPal API keys, and NextAuth secrets
  3. Install dependencies: npm install
  4. Run locally: npm run dev
  5. Deploy to Vercel: connect repo, set environment variables
