• 🌍 Production Ready - Best practices for deployment and security

🚀 Quick Start

Prerequisites

• Node.js 16+ installed
• React Native development environment setup
• Stripe account (Create free account)
• Android Studio (for Android development)

Installation

1. Clone the repository

git clone https://github.com/salmanazamdev/stripe-payment-react-native-app.git
cd stripe-payment-react-native-app

2. Install dependencies

# Install React Native dependencies
npm install

# Install backend dependencies
cd stripe-backend
npm install
cd ..

3. Get your Stripe keys

   • Go to Stripe Dashboard
   • Copy your Publishable key and Secret key

4. Configure your keys

   Backend (stripe-backend/server.js):

   const stripe = require('stripe')('sk_test_YOUR_SECRET_KEY_HERE');

   Frontend (App.tsx):

   setPublishableKey('pk_test_YOUR_PUBLISHABLE_KEY_HERE');

5. Run the application

   Terminal 1 - Start Backend:

   cd stripe-backend
   node server.js
   # Should see: ✅ Server running on port 3000

   Terminal 2 - Start React Native:

   npx react-native run-android

6. Test the payment

   • Tap "Pay Now" button
   • Use test card: 4242 4242 4242 4242
   • Any future expiry date and CVC
   • Complete the payment!

🔧 Configuration

Environment Variables

Create stripe-backend/.env:

STRIPE_SECRET_KEY=sk_test_your_secret_key_here
STRIPE_PUBLISHABLE_KEY=pk_test_your_publishable_key_here
PORT=3000

Network Configuration

For Android Emulator:

const API_URL = 'http://10.0.2.2:3000';

For Physical Device:

const API_URL = 'http://YOUR_COMPUTER_IP:3000';

🎯 How It Works

1. App Initialization - Stripe Provider sets up with publishable key
2. Payment Setup - App calls backend to create payment intent
3. Backend Processing - Server creates customer, ephemeral key, and payment intent
4. Payment Sheet - Beautiful native UI handles card input
5. Secure Processing - Stripe processes payment securely
6. Result Handling - App shows success/error feedback

🧪 Testing

Test Cards

Card Number	Description
4242 4242 4242 4242	Successful payment
4000 0000 0000 0002	Card declined
4000 0000 0000 9995	Insufficient funds
4000 0025 0000 3155	Requires authentication

Running Tests

# Run React Native tests
npm test

# Run backend tests

🛠️ Troubleshooting

Common Issues

❌ "Network request failed"

• Check if backend server is running
• Verify API_URL is correct
• For physical devices, use computer's IP address

❌ "Invalid API key"

• Double-check your Stripe keys
• Ensure you're using test keys for development
• Verify keys are properly set in environment variables

❌ "Payment failed"

• Use valid test card numbers
• Check card expiry date is in the future
• Ensure sufficient test balance

❌ Payment Sheet not opening

• Check server logs for errors
• Verify payment intent creation is successful
• Use "Retry Setup" button to reinitialize

Debug Mode

Enable detailed logging:

// Add to CheckoutScreen.tsx
console.log('🔍 Debug mode enabled');
