Reactjs – Stripe Integration: Show price based on users location

To achieve this functionality and handle VPN users, you can follow these steps:

• User Location Detection:

Implement IP geolocation to determine the user’s approximate location based on their IP address. You can use third-party services like MaxMind’s GeoIP2 or IPinfo.io for this purpose.
Store the user’s location in a user session or a cookie to persist this information.

• Pricing Management:

Create a pricing database or configuration in your backend that maps regions or countries to specific prices. For example, you can have a table that associates countries with their respective prices.
Retrieve the user’s location from the session/cookie and fetch the appropriate price from the pricing database.

• Stripe Integration:

Integrate Stripe into your frontend and backend using Stripe’s official libraries. You’ll need to set up products and prices within Stripe that correspond to the different price points you want to offer.

const express = require('express');
const app = express();

// Middleware for VPN detection (use a VPN detection service)
function detectVPN(req, res, next) {
  // Implement VPN detection logic here
  if (isUsingVPN(req.ip)) {
    // Handle VPN user (e.g., restrict access)
    res.status(403).send('VPN usage is not allowed.');
  } else {
    next(); // Continue processing
  }
}

// Middleware for location-based pricing
function setLocationBasedPrice(req, res, next) {
  const userLocation = req.cookies.userLocation; // Get user's location from cookie
  const price = getPriceForLocation(userLocation); // Fetch price based on location

  req.price = price; // Attach the price to the request object
  next();
}

app.use(detectVPN); // Apply VPN detection middleware globally
app.use(setLocationBasedPrice); // Apply location-based pricing middleware globally

// Route for processing payments
app.post('/checkout', (req, res) => {
  const price = req.price; // Access the price from the request object

  // Create a Stripe checkout session with the appropriate price
  // Redirect the user to Stripe checkout
  // Handle payment success and failure
  // ...
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

Please note that this is a simplified example, and you’ll need to adapt it to your specific requirements and integrate it with your React.js frontend. Additionally, the VPN detection mechanism may require third-party services or libraries to function effectively.
