In express how do I redirect a user to an external url?

Question

I have a payment system using node.js and braintree, when the payment is successful I want to send the user to the back end. My back end is setup elsewhere.

I have tried

res.writeHead(301,   {Location: 'http://app.example.io'} ); res.end(); 

So window.location is obviously not available. I cant think of any ways to redirect a user?

Answer 1

You can do

res.redirect('https://app.example.io');
