It features a React-based storefront with an auto-sliding hero carousel, category and price filters, and product listings served through Redis caching, reducing API response times by up to 20× compared to direct MongoDB queries. Product detail pages support ratings, reviews, and a complete add-to-cart experience for authenticated users. The demo also covers secure Razorpay payment integration with an idempotency check to prevent duplicate orders during webhook retries. Additionally, it demonstrates real-time order status updates using Socket.io, allowing instant status changes without requiring a page refresh. Finally, it showcases an admin dashboard powered by MongoDB Aggregation Pipelines, providing insights such as total revenue, order status distribution, and top-selling products, along with a secure authentication system using JWT access tokens, refresh token rotation, and HTTP-only cookies to protect against XSS attacks.
