`app.use(function(req, res, next) {
    res.setHeader('Access-Control-Allow-Origin', ['http://localhost:4242', 'https://ummyahyasbakery.com']);
    res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS');
    res.setHeader('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept');
    next();
  });
  app.use(cors({ 
    origin: ['http://localhost:3000', 'https://ummyahyasbakery.com'], 
    credentials: true 
   }));

app.post("/create-payment-intent", async (req, res) => {
    const { items } = req.body;
  
    // Create a PaymentIntent with the order amount and currency
    const paymentIntent = await stripe.paymentIntents.create({
      amount: calculateOrderAmount(items),
      currency: "usd",
      automatic_payment_methods: {
        enabled: true,
      },
    });
  
    res.send({
      clientSecret: paymentIntent.client_secret,
    });
  });

  app.listen(process.env.PORT || 4242, () => {
    console.log("Node server listening on port 4242!");
  });`

``````This is the relevant part of the client side: 

`useEffect(() => {
    // Create PaymentIntent as soon as the page loads
    fetch("/create-payment-intent", {
      method: "POST",
      headers: { "Content-Type": "application/json" },
      body: JSON.stringify({ items: selectedProduct }),
    })
      .then((res) => {
        console.log(res)
        if (res.ok) return res.json();
        throw new Error("Status code error: " + res.status);
      })
      .then((data) => setClientSecret(data.clientSecret))
      .catch((error) => console.error("Error:", error));    
  }, [selectedProduct]);`

@EliteSamurai You cannot, as Netlify doesn’t provide runtime node.js hosting, see:

Your options are:

  • Adjust your code to work with Serverless Functions
  • Host your back-end elsewhere and use a Proxy
  • Host your entire application elsewhere
