Question

I’m implementing a little aunthentication routes on my Node app, as simple as this:

 app.get('/admin', function(req, res) {
    res.render('login', { error: false });
  });
  app.post('/admin', function(req, res) {    
    if((adminAccount.username === req.body.username) && 
      (adminAccount.password === req.body.password)) {

      res.redirect('/admin/books');
    }
    else {
      res.redirect('/admin', { error: true });
    }
  });

If I login with the right credentials it works flawless, how ever if I failed, it should make a GET request to /admin by redirect.
However I get: undefined. Redirecting to //127.0.0.1:3000/admin

That makes me thing that res.redirect is making a POST request to /admin intead of a GET one.

What can I do? How do I specify res.redirect to redirect the right way?

It looks ok to me, Can you try doing just this to rule out the error: false being the problem:

res.redirect('/admin');

If you want to flash a message, I would use connect-flash:

app.js:

var flash = require('connect-flash');
app.use(flash());

route:

req.flash('error', 'Woops, looks like that username and password are incorrect.');
res.redirect('/login');

middleware:

res.locals.message = req.flash();

view:

  <% if ( message.error ) { %>
    <div class="message error"><%= message.error %></div>
  <% } %>
