Project Overview

Introduction

The MERN Ecommerce project is a fully functional web-based application that enables users to shop online with ease. The project integrates the power of the MERN stack to handle both frontend and backend seamlessly.

• MongoDB stores all the data, such as user details, product information, and orders.
• Express.js and Node.js form the backend server that handles API requests and business logic.
• React.js creates a responsive and interactive user interface for the frontend.

This project is developed keeping modern ecommerce standards in mind, ensuring a clean, intuitive, and responsive interface for both users and administrators. It is one of the best MERN projects for students who want to understand the practical integration of frontend and backend technologies in a single full-stack application.
