$http request on node js - how to return a value in success $http.post

I am writing angular + node js app , and I have a login method that validates a user and a password using a http post call:

login.js

$scope.userLogin = function (info) {

            $http.post('/authenticate_user', {'name':info.name,'password':info.password})
            .success(function(data) {

            })
            .error(function(data) {
                console.log('Error:'+ data);
            });


        }

on the server.js file I am handling the authnetication:

app.post('/authenticate_user', function(req, res){
    authenticate_user(req, res);
});


var authenticate_user=function(req, res){

 var query= user_details.find({'name': req.body.name});
 res.setHeader("Cache-Control", "private, no-cache, no-store, must-revalidate, max-age=0");
 query.exec( function(err, docs){
    if (docs.length==0) return false;
    res.json(docs[0].password==req.body.password);
});  
}

I want to have the userLogin fuction in my login.js file to have the value of the app.post() method..

something like

   $http.post('/authenticate_user', {'name':info.name,'password':info.password})
            .success(function(data) {
              // what is data includes here? the response for the http post?
              // or what the function I calling to aka authenticate_user, returns - in this case - a boolean value?
            })

I want to have the value from my api post to be transfer to the calling method in the login.js file..

any idea on how to do that?

Thanks

Return a promise instead of hiding it

$scope.userLogin = function (info) {
    return $http.post('/authenticate_user', info);
}

usage

userLogin({name: '', password: ''}).then(function(success) {
  console.log(success)
})
