Smart Supermarket Management System Using MERN Stack and Spring Boot Backend

Abstract-This paper presents the design and implementation of a modern Supermarket Management System (SMS) leveraging React.js for the frontend, Spring Boot for the backend API services, and MongoDB as the NoSQL database. The system aims to digitalize and streamline day-to-day supermarket operations such as inventory management, billing, user management, and report generation. It provides a role-based interface for administrators, staff, and customers. This research outlines system architecture, database modeling, RESTful API design, frontend integration, and security measures. Performance, scalability, and user experience were prioritized during development. The system demonstrates the benefits of using modern web development stacks in enterprise applications. Key Words:Supermarket Management System, React.js, Spring Boot, MongoDB, MERN Stack, Inventory Management, Role-Based Access, RESTful API.
