You have to use Like below

    res.send("<script> window.location = 'http://localhost:8080'; </script>");

Above code is working for me. Hope also for you.

what I use is Body-Parser with Express 4. So you need to assign Body-Parser to Express, and then, you can do something like:

app.post("userName1", function(req, res){

  var username = req.body.userName;

});

Is in bold method used, path the information is sent, name of the input of the form sent respectively.

As for redirection, you can use: res.redirect("URL"), or:

res.send("<script> JAVASCRIPT REDIRECT CODE </script>")

Hope It works for you :)

That link is outdated. ExpressJS now uses body parser as a separate component, which is what you need in order to parse form data properly.

As for redirection, you could use javascript:

window.location = "https://www.google.com"

or, set the redirect header on the server:

res.setHeader("Location", "http://somewhere.com")

which is the same as:

res.location("http://somewhere.com")
