Create e-Commerce Website Using React.js

React has changed the way we build UIs, especially in e-commerce. Top retailers like Shopify, Walmart and Amazon use React’s component based architecture to build scalable, high performance online stores.

Before you start, you should know the basics of React such as state management, component architecture and performance optimization which is key for e-commerce apps.

React’s headless commerce allows developers to build fast, customizable e-commerce websites with smooth user experience across devices. Features like robust search, virtual DOM and reusable components reduce development time and maintainability. Using a headless CMS further speeds up content management in React e-commerce apps.

This guide will take you through building a React e-commerce platform from scratch, covering environment setup, core features, payment integration, SEO optimization and deployment. Whether you’re building your first app or migrating, this step by step guide will give you a solid technical foundation.

Getting Started with React.js for eCommerce

React is the go to for building dynamic web applications, especially in eCommerce. This JavaScript library is great at creating interactive UIs through its component based architecture. React and its ecosystem has many tools and integrations to make development easier and more functional. The virtual DOM only updates what’s needed in the UI so it’s faster and more performant. Unlike traditional web development, React’s modular, reusable components makes building complex eCommerce web applications faster. Declarative syntax makes development easier by making components more intuitive.

The virtual DOM is the key to React’s performance optimization. Instead of manipulating the browser’s DOM directly, React uses a virtual representation for efficient updates and rendering. This means faster page loads and smoother interactions, which is crucial for eCommerce where a 1 second delay can reduce conversions by 7%. React’s scalability is perfect for growing eCommerce apps with more users and product catalogs.

React’s component based design promotes code reuse and maintainability. For example a product component can be reused throughout the app with different props, so you get consistency and save development time. Each React component is key to managing complex UIs and state. Dynamic content keeps customers engaged with fresh, relevant info like targeted promotions and real-time inventory. This modular approach makes managing large scale eCommerce apps and adding features without breaking existing code.

Server side rendering with frameworks like Next.js solves the common single page app problem: SEO. While React apps usually render client side, SSR lets search engines crawl and index content, so your React eCommerce site is more discoverable. For routing, developers use libraries like react-router-dom. These are essential for building scalable, SEO friendly eCommerce web applications.

Setting Up Your React.js Development Environment

Creating a robust React JS development environment is the foundation of any successful react e commerce project. Start by ensuring you have Node.js version 16 or higher installed, as this provides the runtime environment for React’s tooling ecosystem. You’ll also need either npm or yarn as your package manager to handle dependencies and scripts.

Initialize your new react app using Create React App, which provides a solid foundation with modern build tools preconfigured:

npx create-react-app my-ecommerce-store
cd my-ecommerce-store
npm start

Install essential dependencies for eCommerce functionality:

npm install react-router-dom axios styled-components
npm install --save-dev eslint prettier

Set up your project structure to scale with your development. Create a components directory for reusable UI components, a pages directory for route components and a utils directory for helper functions. This will become super important as your e commerce site gets more complex.

Set up development tools to boost productivity and code quality. ESLint will catch errors and enforce coding standards, Prettier will format your code and the React Developer Tools browser extension will give you amazing debugging powers for react components during development.

Initialize with Git to track changes and collaborate. Even for solo projects, Git is essential when deploying to production or reverting bad changes.

Planning Your eCommerce Website Architecture

Good architecture planning is key to long term success and maintainability of your react ecommerce website. Start by designing your component hierarchy, identifying the main sections and their relationships. A typical structure will have a Header component with navigation and search, a main content area for product displays and a Footer component with links and info.

Your routing should mirror common ecommerce user journeys. Plan routes for the homepage, product catalog pages, individual product details, shopping cart, checkout process and user account management. Use react router dom to implement client side routing that doesn’t do full page reloads.

State management becomes important as your application grows. For smaller projects React’s built in context api is sufficient for global state management. But complex ecommerce stores with large product catalogs, user preferences and cart functionality often need more robust solutions like Redux or Zustand. When planning for dynamic features such as real-time updates and interactive components, robust state management ensures smooth data flow and responsiveness. Regular testing of your react application is necessary to ensure functionality and performance, use Jest and React Testing Library.

Design your data management approach early on in the development process. Think about how product info, user authentication states and cart contents will flow through your application. Plan API endpoints for product data fetching, user authentication, order processing and payment gateway integration.

Component reusability should guide your architectural decisions. Design ui components that can adapt to different contexts through props rather than creating multiple similar components. When planning your architecture, consider how you will add dynamic features for scalability and enhanced user experience. This will reduce code duplication and ensure consistency across your ecommerce site.

Building Core eCommerce Components

Any online store is built on its foundation pieces. Start with a ProductCard component that contains product display logic, product title, image, price and “Add to Cart” button. This reusable component will be the building block for all product listings in your app.

// components/ProductCard.js
import React from 'react';
import './ProductCard.css';

const ProductCard = ({ product, onAddToCart }) => {
  return (
    < div className="product-card">
      < img src={product.image} alt={product.title} />
      < h3 className="product-title">{product.title}< /h3>
      < p className="product-price">${product.price}< /p>
      < button onClick={() => onAddToCart(product)}>
        Add to Cart
      < /button>
    < /div>
  );
};

export default ProductCard;

Create a Navigation component that handles category filtering, search and user account access. Allow users to create accounts for a personalized and secure experience. Implement debounced search to reduce API calls as the user types. This will improve the user experience and reduce server load. Additionally, implement a responsive navigation menu to ensure that the app is accessible on different devices.

Build a responsive Header component that adapts to different screen sizes and has all the essential eCommerce elements. The header should have your brand logo, search, user authentication links and a shopping cart icon with dynamic item count. Mobile responsiveness will ensure a seamless user experience and user engagement across all mobile devices.

Product Catalog Implementation

Product catalog functionality forms the core of your e commerce application. Implement data fetching using React hooks, combining useState for managing product data and useEffect for triggering API calls. Structure your fetch product data logic to handle loading states, error conditions, and empty results gracefully. A robust search functionality enhances user experience by helping customers find products quickly and easily.

// hooks/useProducts.js
import { useState, useEffect } from 'react';
import axios from 'axios';

export const useProducts = (category = '') => {
  const [products, setProducts] = useState([]);
  const [loading, setLoading] = useState(true);
  const [error, setError] = useState(null);

  useEffect(() => {
    const fetchProducts = async () => {
      try {
        setLoading(true);
        const response = await axios.get(`/api/products?category=${category}`);
        setProducts(response.data);
      } catch (err) {
        setError(err.message);
      } finally {
        setLoading(false);
      }
    };

    fetchProducts();
  }, [category]);

  return { products, loading, error };
};

Implement filtering and sorting capabilities that enhance user behavior and help customers find products efficiently. Category-based filtering, price ranges, and sorting by popularity or ratings improve the shopping experience and can increase conversion rates. Use URL parameters to make filtered states shareable and bookmarkable.

Add pagination or infinite scrolling for large product catalogs. This approach improves initial page load times and provides better performance on mobile devices with limited processing power. Consider implementing lazy loading for product images to further optimize loading performance.

Product Detail Pages

Product pages need to present all the information but load fast. Design these pages with high quality image galleries with zoom, product descriptions, specs and customer reviews. The layout should guide the user to a purchase decision and have all the information. A well-designed user interface can make the shopping process intuitive and enjoyable, leading to higher user engagement and conversion rates.

Implement product variants for items with multiple options like sizes, colors or configurations. Use React’s state management to track the selected variant and update pricing, availability and images accordingly. This dynamic content updates without page refresh. The product page is where users can browse through the available products and add them to their shopping cart.

Include social proof elements like customer ratings, reviews and related products. These build trust with the customer and can impact purchase decisions. Implement star rating components that show average rating and allow customers to filter reviews by rating.

// components/ProductDetail.js
import React, { useState, useEffect } from 'react';
import { useParams } from 'react-router-dom';

const ProductDetail = () => {
  const { productId } = useParams();
  const [product, setProduct] = useState(null);
  const [selectedVariant, setSelectedVariant] = useState({});

  const handleVariantChange = (variantType, value) => {
    setSelectedVariant(prev => ({
      ...prev,
      [variantType]: value
    }));
  };

  return (
    <div className="product-detail">
      {product && (
        <>
          <div className="product-images">
            {/* Image gallery implementation */}
          </div>
          <div className="product-info">
            <h1>{product.title}</h1>
            <p className="price">${product.price}</p>
            {/* Variant selection UI */}
            <button onClick={() => addToCart(product, selectedVariant)}>
              Add to Cart
            </button>
          </div>
        </>
      )}
    </div>
  );
};


export default ProductDetail;

Implementing Shopping Cart Functionality

The shopping cart represents one of the most critical components in any ecommerce store. Implement cart functionality using React’s context api or a state management library to ensure cart data persists across different pages and user sessions. The cart should handle adding items, removing items, updating quantities, and calculating totals in real-time.

// context/CartContext.js
import React, { createContext, useContext, useReducer } from 'react';

const CartContext = createContext();

const cartReducer = (state, action) => {
  switch (action.type) {
    case 'ADD_TO_CART':
      const existingItem = state.items.find(item => item.id === action.payload.id);
      if (existingItem) {
        return {
          ...state,
          items: state.items.map(item =>
            item.id === action.payload.id
              ? { ...item, quantity: item.quantity + 1 }
              : item
          )
        };
      }
      return {
        ...state,
        items: [...state.items, { ...action.payload, quantity: 1 }]
      };
    case 'REMOVE_FROM_CART':
      return {
        ...state,
        items: state.items.filter(item => item.id !== action.payload)
      };
    default:
      return state;
  }
};

export const CartProvider = ({ children }) => {
  const [cart, dispatch] = useReducer(cartReducer, { items: [] });

  return (
    <CartContext.Provider value={{ cart, dispatch }}>
      {children}
    </CartContext.Provider>
  );
};

export const useCart = () => useContext(CartContext);

Implement persistent storage using localStorage or sessionStorage to maintain cart contents between browser sessions. This functionality prevents cart abandonment due to accidental page refreshes or navigation away from the site. Include logic to sync cart data when users return to your site. Implementing a persistent shopping cart ensures that users do not lose their selections when navigating away from the site.

Create a comprehensive cart component that displays itemized products, quantities, individual prices, and total calculations. Include shipping estimates and tax calculations where applicable. The cart should provide clear feedback when items are added or removed, using toast notifications or other visual cues. Once users have added products to their shopping cart, they need a seamless way to proceed to checkout and complete their purchase efficiently.

Add shopping cart optimization features like recommended products, quantity discounts, or shipping threshold notifications. These elements can increase average order values and improve customer satisfaction by providing value-added suggestions.

User Authentication and Account Management

User authentication is the foundation of any ecommerce site. Build a secure authentication system that handles registration, login and account management and follows best practices for security to protect user data. Choose between custom JWT based authentication or third party services like Firebase Authentication based on your needs.

// hooks/useAuth.js
import { useState, useEffect, useContext, createContext } from 'react';
import axios from 'axios';

const AuthContext = createContext();

export const useAuth = () => useContext(AuthContext);

export const AuthProvider = ({ children }) => {
  const [user, setUser] = useState(null);
  const [loading, setLoading] = useState(true);

  const login = async (email, password) => {
    try {
      const response = await axios.post('/api/auth/login', { email, password });
      setUser(response.data.user);
      localStorage.setItem('token', response.data.token);
      return { success: true };
    } catch (error) {
      return { success: false, error: error.message };
    }
  };

  const logout = () => {
    setUser(null);
    localStorage.removeItem('token');
  };

  const value = {
    user,
    login,
    logout,
    loading
  };

  return (
    < AuthContext.Provider value={value}>
      {children}
    < /AuthContext.Provider>
  );
};

Implement protected routes for sensitive areas like checkout pages, order history and account settings. Use React Router guards to redirect unauthenticated users to login pages and preserve the intended destination for post authentication navigation.

Create user account pages that allow customers to manage their profiles, view purchase history, track orders and update preferences. These features increase customer satisfaction and encourage repeat business by giving them easy account management tools.

Build registration and login forms with validation and user friendly error messaging. Include password strength indicators, email verification and password reset functionality. After a successful login, provide clear feedback to users so they know they have securely accessed their account. Consider adding social login to reduce friction in the user authentication process.

Payment Integration and Checkout Process

Payment processing is one of the most important parts of any e commerce website. Use Stripe as your main payment gateway because of its solid React integration and security features. For greater flexibility and security, consider integrating multiple payment gateways such as PayPal or other trusted providers. Stripe’s @stripe/react-stripe-js library has pre-built components that handle sensitive payment info securely. You can use the CardElement component from the @stripe/react-stripe-js package to collect card details.

// components/CheckoutForm.js
import React, { useState } from 'react';
import { CardElement, useStripe, useElements } from '@stripe/react-stripe-js';

const CheckoutForm = ({ total, onSuccess }) => {
  const stripe = useStripe();
  const elements = useElements();
  const [processing, setProcessing] = useState(false);

  const handleSubmit = async (event) => {
    event.preventDefault();
    setProcessing(true);

    if (!stripe || !elements) return;

    const { error, paymentMethod } = await stripe.createPaymentMethod({
      type: 'card',
      card: elements.getElement(CardElement)
    });

    if (!error) {
      // Process payment with your backend
      const response = await processPayment(paymentMethod.id, total);
      if (response.success) {
        onSuccess(response.order);
      }
    }
    setProcessing(false);
  };

  return (
    < form onSubmit={handleSubmit}>
      < CardElement />
      < button disabled={!stripe || processing}>
        {processing ? 'Processing...' : `Pay $${total}`}
      < /button>
    < /form>
  );
};

export default CheckoutForm;

Design a multi-step checkout that guides users through shipping info, payment details and order review. Each step should validate input before proceeding to prevent errors and improve user experience. Allow users to select their preferred payment method during the checkout process, typically on a dedicated payment step or form. Include progress indicators to show users where they are in the checkout flow. Implement a secure checkout flow to protect user payment information.

Implement multiple payment methods including credit cards, PayPal and digital wallets like Apple Pay and Google Pay. This will accommodate different user preferences and reduce cart abandonment. Make sure all payment gateway integrations are PCI DSS compliant.

Create order confirmation pages that give immediate feedback after successful transaction. Include order numbers, itemized receipts, estimated delivery dates and tracking info when available. Send confirmation emails with similar info so customers have a permanent record of their purchase.

Backend Integration and API Management

API integration connects your React frontend to backend services that handle data, user auth and business logic. Design your API with RESTful principles or GraphQL depending on your data complexity and performance needs.

// services/api.js
import axios from 'axios';

const API_BASE_URL = process.env.REACT_APP_API_URL;

const api = axios.create({
  baseURL: API_BASE_URL,
  timeout: 10000,
});

// Request interceptor for authentication
api.interceptors.request.use((config) => {
  const token = localStorage.getItem('token');
  if (token) {
    config.headers.Authorization = `Bearer ${token}`;
  }
  return config;
});

// Response interceptor for error handling
api.interceptors.response.use(
  (response) => response,
  (error) => {
    if (error.response?.status === 401) {
      localStorage.removeItem('token');
      window.location.href = '/login';
    }
    return Promise.reject(error);
  }
);

export const productAPI = {
  getProducts: (params) => api.get('/products', { params }),
  getProduct: (id) => api.get(`/products/${id}`),
  searchProducts: (query) => api.get(`/products/search?q=${query}`)
};

export const orderAPI = {
  createOrder: (orderData) => api.post('/orders', orderData),
  getOrders: () => api.get('/orders'),
  getOrder: (id) => api.get(`/orders/${id}`)
};

Implement error handling strategies that give users meaningful feedback while logging detailed error info for debugging. Use try-catch blocks around API calls and display user friendly error messages that guide the user to a solution.

Consider using data caching with libraries like React Query or SWR to improve performance and reduce server load. These libraries provide automatic caching, background updates and optimistic updates that enhance the user experience and minimize API calls.

Design your API endpoints to support common eCommerce operations like product CRUD, user management, order processing and inventory management. Make sure to have proper auth and authorisation mechanisms to protect sensitive operations and user data.

Performance Optimization Techniques

Performance impacts user engagement and conversion rates in eCommerce apps. Use React.lazy() and Suspense to reduce initial bundle sizes and initial page load times. This loads components only when needed and feels faster. React's ecosystem includes tools for performance optimization such as lazy loading and code splitting. Using code-splitting can help improve initial load time by breaking your app into smaller, manageable chunks that load on demand.

// App.js with code splitting
import React, { Suspense } from 'react';
import { BrowserRouter as Router, Routes, Route } from 'react-router-dom';

const ProductCatalog = React.lazy(() => import('./pages/ProductCatalog'));
const ProductDetail = React.lazy(() => import('./pages/ProductDetail'));
const Checkout = React.lazy(() => import('./pages/Checkout'));

function App() {
  return (
    <Router>
      <Suspense fallback={<div>Loading...</div>}>
        <Routes>
          <Route path="/products" element={<ProductCatalog />} />
          <Route path="/product/:id" element={<ProductDetail />} />
          <Route path="/checkout" element={<Checkout />} />
        </Routes>
      </Suspense>
    </Router>
  );
}

export default App;

Use image optimization techniques like lazy loading, WebP, and responsive images that adapt to different screen sizes. These reduce bandwidth and load times, especially important for mobile devices with slower connections. Lazy loading can significantly reduce load times by loading images and components only when they are needed.

Use React.memo, useMemo and useCallback to prevent unnecessary re-renders of components. As your app gets more complex and has large product catalogs these become super important to keep performance smooth.

Use virtual scrolling for long product lists with libraries like react-window. This renders only visible items and is a game changer when you have hundreds or thousands of products.

SEO Optimization and Server-Side Rendering

Search engine optimization remains crucial for eCommerce success, making server side rendering an essential feature for react ecommerce websites. Implement Next.js to enable SSR capabilities that ensure search engines can properly crawl and index your product pages.

// pages/products/[id].js (Next.js)
import { GetServerSideProps } from 'next';
import Head from 'next/head';

export default function ProductPage({ product }) {
  return (
    <>
      <Head>
        <title>{product.title} | Your Store</title>
        <meta name="description" content={product.description} />
        <meta property="og:title" content={product.title} />
        <meta property="og:description" content={product.description} />
        <meta property="og:image" content={product.image} />
        <meta property="og:type" content="product" />
        <script type="application/ld+json">
          {JSON.stringify({
            "@context": "https://schema.org/",
            "@type": "Product",
            "name": product.title,
            "description": product.description,
            "offers": {
              "@type": "Offer",
              "price": product.price,
              "priceCurrency": "USD"
            }
          })}
        </script>
      </Head>
      {/* Product component */}
    </>
  );
}

export const getServerSideProps: GetServerSideProps = async ({ params }) => {
  const product = await fetchProduct(params.id);
  return { props: { product } };
};

Implement dynamic meta tags for product pages, categories, and other content. Include Open Graph tags for social media sharing and structured data markup using Schema.org to enable rich snippets in search engine results pages. These elements improve click-through rates and provide better search visibility.

Create XML sitemaps that include all product pages, categories, and important content. Submit these sitemaps to search engines and update them regularly as your product catalog changes. Use proper URL structures that include relevant keywords and maintain consistent navigation patterns.

Optimize your content for technical seo by implementing proper heading structures, alt text for images, and semantic HTML elements. These factors help search engines understand your content better and improve accessibility for users with disabilities.

Mobile Responsiveness and PWA Features

Mobile devices make up over 55% of eCommerce traffic so mobile responsiveness is a must have not a nice to have. Design your app mobile first, start with small screen layouts and then enhance for larger screens.

/* Mobile-first responsive design */
.product-grid {
  display: grid;
  grid-template-columns: 1fr;
  gap: 1rem;
  padding: 1rem;
}

@media (min-width: 768px) {
  .product-grid {
    grid-template-columns: repeat(2, 1fr);
    gap: 1.5rem;
  }
}

@media (min-width: 1024px) {
  .product-grid {
    grid-template-columns: repeat(3, 1fr);
    gap: 2rem;
  }
}

@media (min-width: 1200px) {
  .product-grid {
    grid-template-columns: repeat(4, 1fr);
  }
}

Implement Progressive Web App features to enhance the mobile experience and increase user engagement. Add a web app manifest and service workers to allow installation on mobile home screens and offline browsing of previously visited products.

Design touch friendly building user interfaces with buttons, tap targets and gesture support. Consider swipe gestures for product image galleries and pull to refresh for product lists. Native like interactions increase user engagement on mobile.

Optimise touch interactions and consider thumb reach zones when placing important navigation elements. Users should be able to access critical functions like search, cart and navigation with minimal hand movement on mobile.

Testing and Quality Assurance

Comprehensive testing ensures your react ecommerce website functions correctly across different scenarios and user interactions. Implement unit testing using Jest and React Testing Library to verify component behavior and catch regressions early in the development process.

// __tests__/ProductCard.test.js
import { render, screen, fireEvent } from '@testing-library/react';
import ProductCard from '../components/ProductCard';

const mockProduct = {
  id: 1,
  title: 'Test Product',
  price: 29.99,
  image: 'test-image.jpg'
};

test('renders product information correctly', () => {
  render(<ProductCard product={mockProduct} onAddToCart={jest.fn()} />);

  expect(screen.getByText('Test Product')).toBeInTheDocument();
  expect(screen.getByText('$29.99')).toBeInTheDocument();
  expect(screen.getByAltText('Test Product')).toBeInTheDocument();
});

test('calls onAddToCart when button is clicked', () => {
  const mockAddToCart = jest.fn();
  render(<ProductCard product={mockProduct} onAddToCart={mockAddToCart} />);

  fireEvent.click(screen.getByText('Add to Cart'));
  expect(mockAddToCart).toHaveBeenCalledWith(mockProduct);
});

Implement end-to-end testing using Cypress to verify complete user workflows including browsing products, adding items to cart, and completing purchases. These tests catch integration issues and ensure critical business functions work correctly from the user’s perspective.

Conduct cross-browser testing to ensure compatibility across Chrome, Firefox, Safari, and Edge. Pay particular attention to payment processing and checkout flows, as these critical functions must work reliably across all supported browsers.

Perform performance testing using tools like Lighthouse and GTMetrix to identify bottlenecks and optimization opportunities. Regular performance audits help maintain fast loading speeds and optimal user experiences as your application grows.

Deployment and Production Setup

Deploy your react app to production using modern hosting platforms that provide global content delivery network capabilities and optimized performance. Vercel, Netlify, and AWS Amplify offer excellent React hosting with automatic deployments and SSL certificates.

        vercel-args: '--prod'

Configure environment variables for API endpoints, payment gateway keys, and other sensitive configuration data. Use different environment configurations for development, staging, and production to ensure proper testing and security isolation.

Implement monitoring and error tracking using services like Sentry or LogRocket to capture runtime errors and user session data. These tools provide valuable insights into user behavior and help identify issues before they impact customer satisfaction.

Set up analytics tracking with Google Analytics 4 to monitor user engagement, conversion rates, and business metrics. Configure goal tracking for key events like completed purchases, cart additions, and user registrations to measure your ecommerce site’s performance.

Advanced Features and Future Enhancements

Modern eCommerce needs advanced features to stand out from the competition. Add AI powered product recommendations using machine learning APIs or services that analyze user behavior and purchase history to suggest products.

// components/RecommendationEngine.js
import React, { useState, useEffect } from 'react';
import { getRecommendations } from '../services/recommendations';

const RecommendationEngine = ({ userId, currentProduct }) => {
  const [recommendations, setRecommendations] = useState([]);

  useEffect(() => {
    const fetchRecommendations = async () => {
      try {
        const recs = await getRecommendations({
          userId,
          productId: currentProduct?.id,
          type: 'related_products'
        });
        setRecommendations(recs);
      } catch (error) {
        console.error('Failed to fetch recommendations:', error);
      }
    };

    fetchRecommendations();
  }, [userId, currentProduct]);

  return (
    < section className="recommendations">
      < h3>You might also like< /h3>
      < div className="recommendation-grid">
        {recommendations.map(product => (
          < ProductCard key={product.id} product={product} />
        ))}
      < /div>
    < /section>
  );
};

export default RecommendationEngine;

Add real-time chat support to help customers during the shopping process. This can reduce cart abandonment and increase customer satisfaction by addressing concerns before they become lost sales.

Add social features like user generated content, product reviews and social sharing. These build trust with potential customers and provide social proof that influences buying decisions.

Create administrative dashboards for inventory management, order processing and analytics reporting. These will help you run your business efficiently and provide insights for decision making. For an ecommerce business, these features are essential to scale operations and optimize performance as your store grows. Developers should create a separate admin panel for managing products, users and orders in an eCommerce application.

Security Best Practices

Security represents a critical concern for any ecommerce website handling sensitive customer information and payment data. Implement HTTPS encryption and SSL certificates to protect data transmission between your application and users’ browsers.

// utils/security.js
import DOMPurify from 'dompurify';

// Input sanitization
export const sanitizeInput = (input) => {
  return DOMPurify.sanitize(input.trim());
};

// CSRF token management
export const getCSRFToken = () => {
  return document.querySelector('meta[name="csrf-token"]')?.getAttribute('content');
};

// Secure storage utilities
export const secureStorage = {
  setItem: (key, value) => {
    const encrypted = btoa(JSON.stringify(value));
    sessionStorage.setItem(key, encrypted);
  },

  getItem: (key) => {
    const encrypted = sessionStorage.getItem(key);
    if (!encrypted) return null;

    try {
      return JSON.parse(atob(encrypted));
    } catch {
      return null;
    }
  }
};

Implement input validation and sanitization to prevent XSS attacks and other injection vulnerabilities. Validate all user inputs both client-side and server-side, and sanitize data before displaying it in your user interface.

Use secure authentication practices including proper password hashing, secure session management, and multi-factor authentication where appropriate. Store sensitive data securely and never expose API keys or credentials in client-side code.

Regular security audits and dependency updates help protect against newly discovered vulnerabilities. Use tools like npm audit to identify and resolve security issues in your project dependencies.
