How to create an E-Commerce website with MERN Stack

In the last decade, e-commerce has become the go-to for modern retail.

The technology behind an e-commerce store has the power to make or break the user experience, regardless of whether it’s a new store or upgrading an existing one. A popular combination for building fast, scalable, and modern web applications today is the MERN stack, involving MongoDB, Express.js, React.js, and Node.js.

Today, we will explore why the MERN stack is a great choice for e-commerce development, identify the essential features our site needs, and walk through the step-by-step process of getting started.

Why Choose the MERN Stack for E-Commerce?

The MERN stack is a full JavaScript framework that lets us build an end-to-end application using a single language, JavaScript, on both the client and server sides. Let’s look at why it’s a great fit for e-commerce:

• Real-time performance: Instant updates and responsiveness.
• Seamless integration: APIs, third-party services, and databases work smoothly together.
• Scalability: Easily handle increased traffic and product growth.
• Robust security: Protect user data and transactions efficiently.
• Developer-friendly: Full-stack JavaScript means faster development cycles and better collaboration.

E-Commerce Website Essentials

An e-commerce platform needs more than just a good design. Here are a few essential features and how MERN helps build them:

Benefits of MERN in a Nutshell

• From frontend to backend, write in one language.
• Build with React and reuse across pages.
• Build RESTful APIs with Express and Node.
• MongoDB’s document structure is perfect for product and user data.
• Tons of open-source libraries and community support.

Step-by-Step Guide to Building an E-Commerce Site

Here’s a quick look at how to start creating your e-commerce website with MERN:

1. First, we have to set up the backend made of Node.js, Expres,s and MongoDB. We begin by creating a project directory:

   
   
   mkdir server
   
   cd server
   
   
2. Then, initialize the Node project and install dependencies:

   
   
   npm init -y
   
   npm i express mongoose cors
   
   
3. The `package.json` will include:

   
   
   "dependencies": {
   
   "cors": "^2.8.5",
   
   "express": "^4.18.3",
   
   "mongoose": "^8.2.1"
   
   }
   
   
4. Next, start the backend server:
   

   node index.js
5. Now, we will proceed to set up the Frontend with React. To create the React app, run these commands:

   npx create-react-app client
   
   cd client
   
   
6. Next, install the required packages:
   

   npm i @fortawesome/free-solid-svg-icons
   
   npm i @fortawesome/react-fontawesome
   
   
7. After that, install additional dependencies:

   npm install axios react-router-dom sass
8. The frontend `package.json` might look like:
   

   "dependencies": {
   
   "@fortawesome/free-solid-svg-icons": "^6.5.1",
   
   "@fortawesome/react-fontawesome": "^0.2.0",
   
   "axios": "^1.6.7",
   
   "react": "^18.2.0",
   
   "react-dom": "^18.2.0",
   
   "react-router-dom": "^6.22.3",
   
   "react-scripts": "5.0.1",
   
   "sass": "^1.71.1",
   
   "web-vitals": "^2.1.4"
   
   }
   
   
9. Now, start the frontend development server:

   npm start
