Best E-commerce Website using MERN Stack

E-commerce Website using MERN Stack

A simple project on E-commerce Website that delivers a complete, real-world online shopping experience built using the MERN Stack (MongoDB, Express.js, React, Node.js). This full-stack web application aims to transform the traditional e-commerce flow into a fast, modern, and scalable platform that supports both users and admins.

Designed with Redux Toolkit for efficient state management and Material UI for a smooth, consistent design language, this project offers a hands-on opportunity for students to explore how full-stack technologies work together in a professional-grade e-commerce environment.

The application focuses on usability, scalability, and clean code architecture — making it a strong foundation for understanding modern development practices used in large-scale applications.

Available Features

User Features

1. Product Reviews
Users can write, edit, and delete product reviews. Each update immediately reflects on average ratings and percentage-based star statistics, giving an accurate representation of user satisfaction.

2. Wishlist Management
Shoppers can add or remove items from their wishlist. Each wishlist entry supports personalized notes, making it easier to remember preferences or compare later.

3. Order Management
Users can create new orders, view their order history, and check real-time updates on their order status.

4. Profile Management
Each user can edit their profile information, update their email or username, and manage multiple addresses for convenience.

5. Shopping Cart
A robust shopping cart lets users add products, modify quantities, and view subtotals dynamically. All cart activities are saved to ensure a smooth checkout experience.

Admin Features

1. Product Management
Admins can add, edit, delete, or soft-delete products. The interface allows easy updates to product details like name, price, stock, and descriptions.

2. Order Management
Admins can view all user orders and update their status (pending, shipped, delivered). This makes it easier to maintain order flow in real time.

Security and User Experience

1. Secure Authentication System
Includes signup, login, OTP verification, password reset, and logout features. JWT and cookies are used to manage sessions securely.

2. Intuitive Interface
Material UI enhances the overall design and interactivity, ensuring the layout is visually appealing and accessible.

Scalability and Growth

The backend structure and database schema are designed for scalability. This ensures the platform can easily adapt to more users, products, and transactions as it grows — an essential consideration in real-world e-commerce systems.

Installation Guide (For VS Code)

Follow these steps to set up and run the MERN Ecommerce project locally using Visual Studio Code (VS Code).

Step 1: Prerequisites

Before starting, ensure that you have the following installed:

• Node.js (version 21.1.0 or higher)
• MongoDB (installed and running locally)
• Visual Studio Code

Step 2: Extract and Open the Project

1. Download and extract the project folder.
2. Open the extracted folder in VS Code.

code mern-ecommerce

Step 3: Install Dependencies

This project includes both a frontend and a backend. You need to install dependencies separately for each.

Backend Setup

cd backend
npm install

Frontend Setup

cd frontend
npm install

You can also open two split terminals in VS Code — one for the frontend and one for the backend — to manage them simultaneously.

Step 4: Configure Environment Variables

Create a .env file in both the backend and frontend folders.

Backend .env file:

MONGO_URI="mongodb://localhost:27017/mern-ecommerce"
ORIGIN="http://localhost:3000"
EMAIL="your-email@example.com"
PASSWORD="your-email-password"
LOGIN_TOKEN_EXPIRATION="30d"
OTP_EXPIRATION_TIME="120000"
PASSWORD_RESET_TOKEN_EXPIRATION="2m"
COOKIE_EXPIRATION_DAYS="30"
SECRET_KEY="your-secret-key"
PRODUCTION="false"

Frontend .env file:

REACT_APP_BASE_URL="http://localhost:8000"

Note: Replace placeholder values with your actual details.
Never commit .env files to version control as they contain sensitive information.

Step 5: Data Seeding (Optional)

To quickly test the application with demo data, you can seed the database:

cd backend
npm run seed

This populates your database with sample users, products, and orders.

Step 6: Start the Servers

Backend Server:

cd backend
npm run dev

This starts the backend API server (usually on port 8000).

Frontend Server:

cd frontend
npm start

This starts the React frontend (usually on port 3000).

Once both servers are running, you can open your browser and access the application at:

Frontend: http://localhost:3000
Backend: http://localhost:8000

Usage

The MERN Ecommerce platform supports two primary roles — User and Admin. Each role has its own set of permissions and accessible features.

For Users

1. Account Creation:
   New users can sign up with an email and password. OTP verification ensures secure registration.
2. Browsing Products:
   Users can view available products, filter by categories, and read detailed descriptions.
3. Wishlist and Cart:
   Add products to wishlist or cart, update quantities, and proceed to checkout.
4. Order Tracking:
   After placing an order, users can monitor the status through their dashboard.
5. Profile Customization:
   Users can edit personal details, manage addresses, and change passwords when needed.

For Admins

1. Dashboard Access:
   Admins can log in using credentials and manage the backend through a structured interface.
2. Product Management:
   Add or update products, track inventory, and mark products as inactive (soft delete).
3. Order Management:
   View all user orders, update shipping status, and ensure timely delivery management.
