Integrating Stripe in React Applications

With the rise of online commerce, payment integration has become a crucial aspect of web development. Stripe, a leading payment processing platform, provides robust APIs and libraries for various frameworks, including React. In this blog post, we’ll explore how to integrate Stripe into your React applications, ensuring seamless payment experiences for your users.

What is Stripe?

Stripe is a powerful payment processing platform that allows businesses to accept payments online and in mobile apps. Its developer-friendly APIs simplify tasks, such as managing subscriptions, handling secure payments, and storing customer information. With support for multiple currencies and payment methods, Stripe is a top choice for businesses looking to provide a streamlined payment experience.

Why Use Stripe with React?

React is a popular JavaScript library for building user interfaces, particularly for single-page applications (SPAs). When combined with Stripe, developers can leverage the following advantages:

• Seamless Integration: Stripe offers a comprehensive JavaScript library, making it easier to integrate payment features directly into your React components.
• Security: Stripe handles sensitive payment information securely, reducing the risks associated with handling sensitive data in your application.
• Customizable UI: You can create a tailored payment flow that matches your application’s design and user experience.

Setting Up Your React Application

Before we dive into the integration, ensure that you have a React application ready. You can create a new one using Create React App by running:

npx create-react-app my-stripe-app

Once your React application is set up, navigate into the project folder:

cd my-stripe-app

Installing Stripe and Required Libraries

To get started with Stripe, you’ll need to install the Stripe.js library and the React wrapper provided by Stripe. Use the following command:

npm install @stripe/stripe-js @stripe/react-stripe-js

Creating a Stripe Account

If you don’t have a Stripe account yet, head over to Stripe’s website and create one. After creating your account, you’ll be able to access your API keys from the Dashboard. You’ll find both publishable and secret keys; for frontend integration, we only need the publishable key.

Setting Up the Stripe Provider

Next, you need to wrap your application with the Elements provider from the React Stripe library. This will provide the necessary context to your components.

import React from 'react';
import ReactDOM from 'react-dom';
import { Elements } from '@stripe/react-stripe-js';
import { loadStripe } from '@stripe/stripe-js';
import App from './App';

const stripePromise = loadStripe('YOUR_PUBLISHABLE_KEY');

ReactDOM.render(
  
    
  ,
  document.getElementById('root')
);

Replace YOUR_PUBLISHABLE_KEY with your actual Stripe publishable key.

Creating the Payment Form

Now, let’s create a simple payment form in a new component:

import React from 'react';
import { CardElement, useStripe, useElements } from '@stripe/react-stripe-js';

const PaymentForm = () => {
  const stripe = useStripe();
  const elements = useElements();

  const handleSubmit = async (event) => {
    event.preventDefault();

    if (!stripe || !elements) {
      return;
    }

    const cardElement = elements.getElement(CardElement);
    const { error, paymentMethod } = await stripe.createPaymentMethod({
      type: 'card',
      card: cardElement,
    });

    if (error) {
      console.error(error);
    } else {
      console.log('Payment Method:', paymentMethod);
      // Here you would typically send the paymentMethod.id to your server for processing.
    }
  };

  return (
    
      
      
        Pay
      
    
  );
};

export default PaymentForm;

The CardElement component handles input for card information, and the handleSubmit function processes the form submission, creating a payment method.

Integrating the Payment Form

Now, let’s integrate the payment form into our main application component. Open App.js and import the PaymentForm component:

import React from 'react';
import PaymentForm from './PaymentForm';

function App() {
  return (
    

      
Stripe Payment Integration
      
    
  );
}

export default App;

Setting Up the Backend

While we’ve worked on the frontend, you’ll need a backend server to handle sensitive data securely, like creating a payment intent and confirming payments. Below is a simple example of a Node.js/Express server:

const express = require('express');
const stripe = require('stripe')('YOUR_SECRET_KEY');
const bodyParser = require('body-parser');

const app = express();
app.use(bodyParser.json());

app.post('/create-payment-intent', async (req, res) => {
  const { amount } = req.body;

  try {
    const paymentIntent = await stripe.paymentIntents.create({
      amount,
      currency: 'usd',
    });

    res.send({
      clientSecret: paymentIntent.client_secret,
    });
  } catch (error) {
    res.status(500).send({ error: error.message });
  }
});

const PORT = process.env.PORT || 3001;
app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`);
});

Ensure to replace YOUR_SECRET_KEY with your actual Stripe secret key. This server creates a payment intent which the frontend can then use to confirm the payment.

Handling Payment Completion

To handle the payment on the frontend, update the `handleSubmit` function to call your backend when creating a payment intent:

const handleSubmit = async (event) => {
  event.preventDefault();

  if (!stripe || !elements) {
    return;
  }

  const cardElement = elements.getElement(CardElement);

  // Requesting the server for the payment intent
  const response = await fetch('/create-payment-intent', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ amount: 1000 }), // example amount in cents
  });

  const paymentIntent = await response.json();

  const { error, paymentMethod } = await stripe.confirmCardPayment(paymentIntent.clientSecret, {
    payment_method: {
      card: cardElement,
    },
  });

  if (error) {
    console.error(error);
  } else {
    console.log('Payment Method:', paymentMethod);
    // Further processing, such as showing a success message, can be done here.
  }
};

This function fetches the payment intent from your backend, which is then used to confirm the payment with the card details.
