ECommerce store with Custom CMS in Nextjs, mongoDB

🚀 Scalable Multi-Currency eCommerce Store + Admin CMS (Full-Stack, Optimized)

This is a full-stack eCommerce platform built with scalability, speed, and flexibility in mind. It includes a fully functional storefront and a secure, high-performance admin CMS for managing products, collections, and homepage content.

The app intelligently handles regional pricing, cart persistence, and page revalidation while following backend best practices such as optimized MongoDB queries and secure API design.

🌟 Core Features:

💸 Multi-Currency Support: Detects user location and adjusts product prices accordingly.

🏠 Customizable Homepage: Admins can update banners, featured categories, and products using MongoDB + API-based CRUD.

🛒 Persistent & Reactive Cart: Cart state revalidates on every product update or page refresh.

⚡ Super-Fast Performance: Uses a hybrid of SSR, SSG, ISR, and client-side rendering for lightning-fast loads with Vercel CDN + optimized images.

📈 SEO & Social Sharing: Dynamic Open Graph metadata (title, description, image) for each product and page.

🔐 Security & Backend Architecture:

🔒 Secure API Layer: Admin routes use HTTP-only and SameSite cookies for secure session management.

⚙️ Optimized MongoDB Access: Uses lean queries, projections, and aggregation pipelines to reduce DB load—especially in dashboard analytics.

💡 Best Practices Applied: RESTful route structure, DTOs for input validation, and secure data access patterns.

🔄 ISR + On-Demand Revalidation: Admin-triggered cache invalidation ensures that any store change reflects instantly without full rebuilds.
