Technical Implementation

Frontend Development with React.js

The frontend of QualityZon is crafted with React.js, ensuring a dynamic and responsive user interface. Key aspects include:

• Component-Based Architecture: Modular and reusable components for scalability and maintainability.
• State Management: Utilizes Redux for efficient state management across the application.
• Routing: Implemented with React Router for seamless navigation and user experience.
• Performance Optimization: Code splitting, lazy loading, and optimized asset delivery through Vercel's CDN.

// Example: ProductList.jsx
import React, { useEffect, useState } from 'react'
import axios from 'axios'
import ProductCard from './ProductCard'

const ProductList = () => {
  const [products, setProducts] = useState([])

  useEffect(() => {
    const fetchProducts = async () => {
      const res = await axios.get('/api/products')
      setProducts(res.data)
    }
    fetchProducts()
  }, [])

  return (
    <div className="product-list">
      {products.map(product => (
        <ProductCard key={product.id} product={product} />
      ))}
      <style jsx>{`
        .product-list {
          display: flex;
          flex-wrap: wrap;
          justify-content: space-around;
        }
      `}</style>
    </div>
  )
}

export default ProductList

Backend Development with Node.js and Express.js

QualityZon's backend is powered by Node.js and Express.js, deployed as serverless functions on AWS Lambda. This setup ensures scalability and high availability.

• API Design: RESTful APIs for handling user authentication, product management, order processing, and more.
• Middleware: Utilizes middleware for authentication, logging, error handling, and request validation.
• Database Interaction: Implements Mongoose for interacting with MongoDB, ensuring efficient data operations.

// Example: serverless function for fetching products
const mongoose = require('mongoose')
const Product = require('../../models/Product')

mongoose.connect(process.env.MONGODB_URI, {
  useNewUrlParser: true,
  useUnifiedTopology: true,
})

exports.handler = async (event) => {
  try {
    const products = await Product.find({})
    return {
      statusCode: 200,
      body: JSON.stringify(products),
    }
  } catch (error) {
    return {
      statusCode: 500,
      body: JSON.stringify({ message: 'Error fetching products' }),
    }
  }
}

Payment Integration with Stripe and Razorpay

Integrating multiple payment gateways enhances flexibility and user convenience.

• Stripe Integration: Handles credit card payments, subscriptions, and invoicing.
• Razorpay Integration: Supports a variety of payment methods popular in specific regions.

// Example: PaymentHandler.jsx
import React from 'react'
import { loadStripe } from '@stripe/stripe-js'
import { useRouter } from 'next/router'

const stripePromise = loadStripe(process.env.NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY)

const PaymentHandler = ({ amount }) => {
  const router = useRouter()

  const handleCheckout = async () => {
    const stripe = await stripePromise
    const res = await fetch('/api/create-checkout-session', {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({ amount }),
    })
    const session = await res.json()
    const result = await stripe.redirectToCheckout({
      sessionId: session.id,
    })
    if (result.error) {
      alert(result.error.message)
    }
  }

  return (
    <button onClick={handleCheckout}>
      Checkout with Stripe
    </button>
  )
}

export default PaymentHandler

Shipping Logistics Integration

Automates shipping processes by integrating with major logistics providers.

• Real-Time Tracking: Provides users with up-to-date tracking information for their orders.
• Automated Shipping Calculations: Calculates shipping costs based on destination, weight, and delivery speed.

// Example: ShippingService.js
import axios from 'axios'

const SHIPPING_API_URL = process.env.SHIPPING_API_URL

export const calculateShipping = async (order) => {
  const res = await axios.post(`${SHIPPING_API_URL}/calculate`, order)
  return res.data
}

export const trackShipment = async (trackingNumber) => {
  const res = await axios.get(`${SHIPPING_API_URL}/track/${trackingNumber}`)
  return res.data
}

Hybrid Deployment with Vercel and AWS Lambda

The hybrid deployment strategy leverages the strengths of both Vercel and AWS Lambda.

• Vercel: Hosts the frontend, providing edge caching, fast deployments, and seamless integration with Next.js.
• AWS Lambda: Runs backend serverless functions, offering scalability, cost-efficiency, and integration with other AWS services.

# Vercel Deployment
vercel deploy

# AWS Lambda Deployment using Serverless Framework
