Fashion Store E-Commerce using MERN Stack

This E-commerce site project uses the MERN (MongoDB, Express.js, React.js, and Node.js) stack to deliver a fully functional online shopping experience. Users can explore a diverse range of products, filter items based on criteria like price range and product type, add selected items to their cart and view the total price.

Output Preview: Let us have a look at how the final output will look like

Prerequisites

Approach to create Fashion Store E-Commerce

Products are fetched from a MongoDB database and displayed on the front end.
Users can filter products by price range and type .
Products can be added or removed from the shopping cart.
The total price of items in the cart is displayed on the navbar.

Steps to create the project:

Step 1: Ctreate a folder for the backend.

mkdir <<name of project>>
cd <<name of project>>

Step 2: Initialize the Node project using the following command.

npm init -y

Step 3: Install the required dependencies:

npm i express mongoose nodemon cors

Folder structure(Backend):

Screenshot-2024-03-10-104441

The updated Dependencies in package.json file will look like:

 "dependencies": {
    "cors": "^2.8.5",
    "express": "^4.18.3",
    "mongoose": "^8.2.1",
    "nodemon": "^3.1.0"
  }

Code Example: Create the required files as shown in the folder structure and add the following codes.

Javascript

// index.js

const express = require('express');
const mongoose = require('mongoose');
const app = express();
const PORT = process.env.PORT || 5000;
const cors = require('cors');

mongoose.connect('Your MongoDB URI',
    {
        useNewUrlParser: true,
        useUnifiedTopology: true
    }
);

app.use(express.json());
app.use(cors());

const productSchema = new mongoose.Schema({
    name: String,
    type: String,
    description: String,
    price: Number,
    image: String,
});

const Product = mongoose.model('Product', productSchema);

const seedDatabase = async () => {
    try {
        await Product.deleteMany();

        const products = [
            {
                name: 'GFG Hoodie-White',
                type: 'Clothing',
                description: 'Comfortable to wear for the winters',
                price: 50,
                image: 
'https://media.geeksforgeeks.org/wp-content/uploads/20240103185713/hoodie.jpg'
            },
            {
                name: 'GFG T-shirt',
                type: 'Clothing',
                description: 'Very smooth and comfortable to wear',
                price: 25,

            },
            {
                name: 'GFG Hoodie-black',
                type: 'Clothing',
                description: 'Comfortable to wear for the winters',
                price: 60,
                image:

            },
            {
                name: 'GFG-Bag',
                type: 'Stationary',
                description: 'HAndy bag for keeping all your equipmements',
                price: 120,
                image: 
'https://media.geeksforgeeks.org/wp-content/uploads/20230407154213/gfg-bag.jpg'
            },
        ];

        await Product.insertMany(products);
        console.log('Database seeded successfully');
    } catch (error) {
        console.error('Error seeding database:', error);
    }
};

seedDatabase();

app.get('/api/products', async (req, res) => {
    try {
        const allProducts = await Product.find();

        res.json(allProducts);
    } catch (error) {
        console.error(error);
        res.status(500)
            .json({ error: 'Internal Server Error' });
    }
});

app.listen(PORT, () => {
    console.log(
        `Server is running on port ${PORT}`
    );
});

Step 4: Start the Server

In the terminal, run the following command to start the server:

node index.js

Step 5: Set up React frontend using the command.

npx create-react-app client
cd client

Step 6: Install the required dependencies.

npm i @fortawesome/free-solid-svg-icons
npm i @fortawesome/react-fontawesome
npm i axios

Dependencies:

"dependencies": {
    "@fortawesome/free-solid-svg-icons": "^6.5.1",
    "@fortawesome/react-fontawesome": "^0.2.0",
    "@testing-library/jest-dom": "^5.17.0",
