Hi,

This article covers making payment using nodejs and stripe . If you want to build a simple shopping cart with stripe as payment gateway this article covers it

Step #1: Install the module needed for the project in your app

we’ll be needing just express,nodemailer and stripe for this

npm install express stripe nodemailer dotenv

this how our folder structure would look like

-routes
--payment.js
server.js

in order to use stripe make sure you get your secret key from stripe

Step #2: Add this in your server.js file

const express = require("express");
const dotenv = require("dotenv");
const PORT = process.env.PORT || 5000;
dotenv.config();

const app = express();
const router = express.Router();
const paymentRoutes = require("./routes/payment");

app.use("/api", paymentRoutes);
app.listen(PORT, () => console.log(`Listening on ${PORT}`));
app.get("/h", (req, res) => {
  res.send("Successful response.");
});
app.use("/", router);

Step #3: Add this in your .env file

STRIPE_SECREY_KEY=sk_test_
GOOGLE_APP_EMAIL=
GOOGLE_APP_PW=

Step #4: Add this in your payment.js file

const router = require("express").Router();
const Stripe = require("stripe");
const stripe = Stripe(process.env.STRIPE_SECREY_KEY);
const nodemailer = require("nodemailer");

//make a post request
router.post("/payment", (req, res) => {
// amount to be paid ,it has to be amount * 100 in order to get the exact amount to be charged
 // get the price from the frontend
  let totalPrice = Math.round(req.body.totalPrice * 100);
 //hardcoded price without front-end
 let totalPrice = 500 * 100
// customer email
  stripe.customers
    .create({
      email: "t@gmail.com"
    })
    .then(customer => {
// create a source
      return stripe.customers.createSource(customer.id, {
        source: "tok_visa"
      });
    })
    .then(source => {
// create charges
      return stripe.charges.create({
          amount: totalPrice,
          currency: "usd",
          customer: source.customer,
        },
// email template
        function (err, charge) {
          if (err) {
            console.log(err);
          } else {
            var emailTemplate = `Hello , \n
  thank you for your order! \n
  Amount: ${charge.amount / 100} \n
 `;
// to get GOOGLE_APP_PW you need to enable 2 step verification on your google account
            let mailTransporter = nodemailer.createTransport({
              service: "gmail",
              auth: {
                user: process.env.GOOGLE_APP_EMAIL,
                pass: process.env.GOOGLE_APP_PW
              }
            });

            let details = {
              from: process.env.GOOGLE_APP_EMAIL,
              to: `t@gmail.com`,
              subject: "shipping",
              text: emailTemplate
            };
            mailTransporter.sendMail(details, err => {
              if (err) {
                console.log(err);
              } else {
                console.log("email sent");
              }
            });
          }
        }
      );

    })
    .then(async charge => {
      console.log("charge>", charge);
// after a successful payment
      res.json({
        success: true,
        message: "Successfully made a payment"
      });
    })
    .catch(err => {
      res.status(500).json({
        success: false,
        message: err.message
      });
    });
});
module.exports = router;
