How to redirect from one domain to another in Express?

Question

To be precise, my website is currently being redirected to appID-appspot.com

How can I force a redirect to my custom domain ?

That is, when gets "appID-appspot.com", redirect to "custom domain".

Answer 1

You can use regular expression route matching of express.

app.get(/appID-appspot.com/, function (req, res) {
  res.redirect('custom_domain');
}

/appID-appspot.com/

matches the url and redirects to customdomain, if the URL contains that part.

Add the above to top of the routes so that it gets redirected first.

Answer 2

You should use res.redirect(301, 'http://example.com');

Full example:

router.get('/', function(req, res){
  res.redirect(301, 'custom domain');
});
