Abstract:

This postgraduate project aims to develop a comprehensive e-commerce platform using the MERN stack (MongoDB, Express.js, React, Node.js). The project focuses on creating a scalable and feature-rich online shopping experience, combining a robust backend, dynamic frontend, and efficient data storage. The integration of the MERN stack ensures a seamless and responsive web application for both users and administrators.

Existing System:

Current e-commerce systems may face challenges related to scalability, real-time updates, and a lack of modern web development features. Many systems also rely on multiple technologies, leading to complex integrations. This project seeks to address these issues by proposing a unified and efficient solution using the MERN stack.

Proposed System:

The proposed system introduces an e-commerce platform built on the MERN stack, ensuring a cohesive and streamlined development process. It incorporates features such as user authentication, product management, shopping cart functionality, and secure payment processing. The use of React for the frontend guarantees a responsive and interactive user interface.

Problem Statement:

Existing e-commerce platforms may struggle with outdated technologies, scalability issues, and complex integrations. This project addresses the need for a modern, scalable, and unified e-commerce solution using the MERN stack, ensuring a smooth shopping experience for users.

Motivation:

The motivation behind this project arises from the increasing demand for efficient and user-friendly e-commerce platforms. As online shopping continues to grow, there is a need for scalable and modern solutions that provide a seamless experience for both customers and administrators. This project is motivated by the desire to contribute to the evolution of e-commerce technology.
