Sending data to the response along with a redirect in Express and NodeJS

I am trying to send data from MongoDB through a redirect using Express.

I am fairly new to working with the server and connecting it to a front-end, so please be easy on me if I have any huge misunderstandings.

Here is an example of my code and what I am trying to do:

app.get('/dashboard', requireLogin, function(req, res) {
  res.render('dashboard.jade');
});
app.get('/api/posts',function(req, res) {
  return Post.find(function(err, posts) {
    if (!err) {
      console.log('Retrieving all posts.');
      res.send(posts);
      res.redirect('/dashboard');
    } else {
      return console.log(err);
    }
  });
}); 

When I render dashboard.jade I have data that is being used in the template to display posts. What I'd like to do is make any GET calls to /api/posts retrieve the posts data from Mongo and send it to the route /dashboard with the post data it retrieved.
