Node Elm
node-elm is a Node.js and MongoDB backend framework designed for building data-driven applications, specifically e-commerce systems and food delivery management platforms. It provides a foundation for managing product catalogs, shopping carts, and payment workflows.
The system includes a dedicated administrative management dashboard for tracking system statistics and managing users and merchants through role-based access control. It also features a digital coupon management system for tracking and exchanging promotional rewards.
The framework incorporates geolocation services for IP-based positioning and distance calculations between users and stores. Additional capabilities cover order processing with transaction snapshots, user rating collection, and traffic monitoring tools for generating business statistics.
