To create the user interface for our payment app, we will be using React, a popular JavaScript library for building user interfaces. React allows us to create reusable components that encapsulate the UI logic and can be easily composed to form the complete user interface.
Here is an example of a simple React component that renders a payment form:
1import React, { useState } from 'react';
2
3const PaymentForm = () => {
4 const [cardNumber, setCardNumber] = useState('');
5 const [expirationDate, setExpirationDate] = useState('');
6 const [cvv, setCvv] = useState('');
7
8 const handleSubmit = (e) => {
9 e.preventDefault();
10 // Perform form validation and payment processing logic here
11 console.log('Payment submitted!');
12 }
13
14 return (
15 <form onSubmit={handleSubmit}>
16 <input type="text" value={cardNumber} onChange={(e) => setCardNumber(e.target.value)} placeholder="Card Number" />
17 <input type="text" value={expirationDate} onChange={(e) => setExpirationDate(e.target.value)} placeholder="Expiration Date" />
18 <input type="text" value={cvv} onChange={(e) => setCvv(e.target.value)} placeholder="CVV" />
19 <button type="submit">Pay Now</button>
20 </form>
21 );
22}
23
24export default PaymentForm;In this example, we are using React's useState hook to manage the state of the form inputs. The form submission is handled by the handleSubmit function, where you can perform form validation and payment processing logic. When the form is submitted, the payment information is logged to the console.
Feel free to customize this example according to your specific UI requirements and payment processing logic. Next, we will learn about implementing user authentication for our payment app.
