  stripe.redirectToCheckout({
    lineItems: [{
      price: priceId,
      quantity: 1
    }],
    mode: 'subscription',
    successUrl: 'https://your-app.com/dashboard',
    cancelUrl: 'https://your-app.com/pricing',
  });
}
// Backend: Handle webhook events
app.post('/webhook', async (req, res) => {
  const event = req.body;
  
  switch (event.type) {
    case 'checkout.session.completed':
      const session = event.data.object;
      await activateSubscription(session.customer);
      break;
    case 'customer.subscription.updated':
      const subscription = event.data.object;
      await updateSubscriptionStatus(subscription);
