I'm using node.js and passport for authentication, and I need to send 'login failed' message to the client if a user failed to authenticate. My application uses also express middleware. I'm using angular.js in the client.

Currently I'm using that command to show a static html:

var loginStatus = 'Failed';
res.sendfile('views/login.html'); // What should I add/change here in order to send the loginStatus variable ?

And this is my angular.js controller:

function MainController($scope) {
   $scope.loginStatus = // What should I write here in order to get 'Failed' ?
}

I've posted my questions on the remarks above.

you can't. you can only use angular.js to call node.js api and get the returned data using a callback. – zs2020 Aug 05 '13 at 13:59
So I need to configure the route for the login.html on my controller template ? If I do that, how can I get a callback from the server ? – ohadinho Aug 05 '13 at 14:15
yes. you should use angular to handle routings. angualr is a selfcontained mvc framework, your node.js becomes just your SOA layer. – zs2020 Aug 05 '13 at 14:17
ok, so how do I get a callback from the server ? – ohadinho Aug 05 '13 at 14:25
You're using express right? – dcodesmith Aug 05 '13 at 14:37
yes. I'm using express as my app middleware – ohadinho Aug 05 '13 at 14:41
