How Do You Build an E-commerce App With Multi-Currency Exchange?
Before starting this project, ensure you have your free API key from CurrencyFreaks.
Step 1: Project Setup
If you haven't already, create a new React app:
npx create-react-app ecommerce-app
cd ecommerce-app
We'll use axios for API calls:
npm install axios
Inside the src directory, create a components folder for your components and a styles.css file for global styles.
Your folder structure should look like this:
ecommerce-app/
├── src/
│ ├── components/
│ │ ├── Login.js
│ │ ├── Store.js
│ │ ├── Cart.js
│ │ ├── CurrencySelector.js
│ ├── App.js
│ ├── index.js
│ ├── styles.css
Step 2: Updated Components
1. App.js
The main component manages authentication and displays the login or store page:
import React, { useState } from 'react';
import Login from './components/Login';
import Store from './components/Store';
import './styles.css'; // Import global styles
function App() {
const [isLoggedIn, setIsLoggedIn] = useState(false);
return (
<div>
{!isLoggedIn ? (
<Login onLogin={() => setIsLoggedIn(true)} />
) : (
<Store />
)}
</div>
);
}
export default App;
2. Login.js
Handles user authentication.
import React, { useState } from 'react';
function Login({ onLogin }) {
const [username, setUsername] = useState('');
const [password, setPassword] = useState('');
const handleLogin = () => {
if (username === 'jfreaks' && password === 'password') {
onLogin();
} else {
alert('Invalid username or password. Please try again.');
}
};
return (
<div id="login-container">
<h1>Login</h1>
<input
type="text"
placeholder="Enter username"
value={username}
onChange={(e) => setUsername(e.target.value)}
/>
<input
type="password"
placeholder="Enter password"
value={password}
onChange={(e) => setPassword(e.target.value)}
/>
<button className="btn" onClick={handleLogin}>
Login
</button>
</div>
);
}
export default Login;
3. Store.js
Displays products and the cart.
import React, { useState, useEffect } from 'react';
import Cart from './Cart';
import CurrencySelector from './Selector';
import axios from 'axios';
const products = [
{ id: 1, name: 'Winter Coat', price: 50, img: 'https://www.refinery29.com/images/11620583.jpg?format=webp&width=720&height=864&quality=85&crop=5%3A6' },
{ id: 2, name: 'Snow Boots', price: 80, img: 'https://d1nymbkeomeoqg.cloudfront.net/photos/25/44/375879_18149_XL.jpg' },
{ id: 3, name: 'Winter Gloves', price: 20, img: 'https://img.drz.lazcdn.com/static/pk/p/403b604000041ed95cfe42e46931b36f.jpg_960x960q80.jpg_.webp' },
];
function Store() {
const [cart, setCart] = useState([]);
const [currency, setCurrency] = useState('USD'); // Default currency
const [exchangeRates, setExchangeRates] = useState({ USD: 1 }); // Default rates
// Fetch exchange rates once when the component mounts
useEffect(() => {
const fetchExchangeRates = async () => {
try {
const response = await axios.get(
'https://api.currencyfreaks.com/v2.0/rates/latest?apikey=YOUR_APIKEY'
);
setExchangeRates(response.data.rates);
} catch (error) {
console.error('Error fetching exchange rates:', error);
setExchangeRates({ USD: 1 }); // Fallback to default rates
}
};
fetchExchangeRates();
}, []);
// Add product to cart
const addToCart = (product) => {
setCart((prevCart) => {
const existingItem = prevCart.find((item) => item.id === product.id);
if (existingItem) {
return prevCart.map((item) =>
item.id === product.id ? { ...item, quantity: item.quantity + 1 } : item
);
}
return [...prevCart, { ...product, quantity: 1 }];
});
};
// Get currency symbol for display
const currencySymbol = (currency) => {
const symbols = { USD: '$', EUR: '€', GBP: '£', PKR: '₨', CAD: 'CA$' };
return symbols[currency] || '$';
};
return (
<div id="web-page">
<h1>CurrencyFreaks Store for Shopping</h1>
{/* Dropdown to select currency */}
<CurrencySelector currency={currency} setCurrency={setCurrency} />
{/* Display products */}
{products.map((product) => (
<div key={product.id} className="product">
<img src={product.img} alt={product.name} />
<span>{product.name}:</span>
<span className="product-price">
{currencySymbol(currency)}
{(product.price * (exchangeRates[currency] || 1)).toFixed(2)}
</span>
<button className="btn" onClick={() => addToCart(product)}>
Add to Cart
</button>
</div>
))}
{/* Cart component */}
<Cart cart={cart} currency={currency} exchangeRates={exchangeRates} />
</div>
);
}
export default Store;
4. Cart.js
Displays the cart items.
import React from 'react';
function Cart({ cart, currency, exchangeRates }) {
const currencySymbol = (currency) => {
const symbols = { USD: '$', EUR: '€', GBP: '£', PKR: '₨', CAD: 'CA$' };
return symbols[currency] || '$';
};
const total = cart.reduce(
(sum, item) => sum + item.price item.quantity exchangeRates[currency],
0
);
return (
<div id="cart">
<h2>Your Cart ({cart.length} items)</h2>
<table id="cart-items">
<thead>
<tr>
<th>Product</th>
<th>Price</th>
<th>Quantity</th>
<th>Total</th>
</tr>
</thead>
<tbody>
{cart.map((item) => (
<tr key={item.id}>
<td>{item.name}</td>
<td>{currencySymbol(currency)}{(item.price * exchangeRates[currency]).toFixed(2)}</td>
<td>{item.quantity}</td>
<td>{currencySymbol(currency)}{(item.price item.quantity exchangeRates[currency]).toFixed(2)}</td>
</tr>
))}
</tbody>
</table>
<div id="cart-total">
Total: {currencySymbol(currency)}{total.toFixed(2)}
</div>
</div>
);
}
export default Cart;
5. CurrencySelector.js
Dynamically fetches and displays currencies.
import React, { useEffect, useState } from 'react';
function CurrencySelector({ currency, setCurrency }) {
const [currencies, setCurrencies] = useState([]);
useEffect(() => {
// Fetch all supported currencies
const fetchCurrencies = async () => {
try {
const response = await fetch(
'https://api.currencyfreaks.com/v2.0/supported-currencies'
);
const data = await response.json();
const supportedCurrencies = data.supportedCurrenciesMap;
// Format the data for dropdown
const formattedCurrencies = Object.keys(supportedCurrencies).map((key) => ({
code: key,
name: supportedCurrencies[key].currencyName,
}));
setCurrencies(formattedCurrencies);
} catch (error) {
console.error('Error fetching supported currencies:', error);
}
};
fetchCurrencies();
}, []);
return (
<div className="form-group">
<label>Select Currency:</label>
<select
value={currency}
onChange={(e) => setCurrency(e.target.value)} // Update currency state
>
{currencies.map((curr) => (
<option key={curr.code} value={curr.code}>
{curr.code} - {curr.name}
</option>
))}
</select>
</div>
);
}
export default CurrencySelector;

Step 4: Run the App
Start the development server:
npm start
The username is jfreaks while the password is "password".
As you can see, the prices are in USD. When we add a product to the cart, you can see it updated on the left side:
However, we want to show prices in PKR. Therefore, we will click on the "Select Currency" dropdown given at the top. This dropdown fetches the supported currencies from CurrencyFreaks. This endpoint is free of cost.
When you choose any currency, you will see the prices converted to that currency as shown below:
As you can see, the prices in our checkout cart have also been updated. It also calculates the Total cost if you select more than one item:
