Integrate Stripe Payment Gateway with Node.js backend.md

Procedures for integrating the stripe payment gateway with Node.js Express.js backend:

• Install stripe package from npm

$ npm install stripe

• Import the Stripe module in your backend server file

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

• Create an endpoint in your backend server to receive the payment details from the frontend

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

app.use(express.json());

app.post('/charge', async (req, res) => {
  const { amount, currency, source } = req.body;
  try {
    const charge = await stripe.charges.create({
      amount,
      currency,
      source
    });
    // Send success response to frontend
    res.send('Payment successful!');
  } catch (err) {
    console.log(err);
    // Send error response to frontend
    res.status(500).send('Payment failed!');
  }
});
