Medium, creating a splash, welcome directive

gistfile1.js

app.directive('welcome', ['$routeParams', '$location', '$window', 'Login', '$timeout', function($routeParams, $location, $window, Login, $timeout) {

  var link = function(scope,element,attrs) {

    scope.loading = true;

    var request_uri = $location.host();
    var apMac = $routeParams.mac || $routeParams.sip;

    Login.welcome({request_uri: request_uri, mac: apMac}).$promise.then(function(results) {
      scope.loading = undefined;
      scope.welcome = results.welcome;
      if (results.timeout > 0) {
        var timeout = results.timeout * 1000;
        var redirectTo = results.success_url || 'https://google.com';
        $timeout(function() {
          $window.location.href = redirectTo;
        },timeout);

      }
    });

  };

  return {
    link: link,
    replace: true,
    scope: false,
    template: '<div><p ng-bind-html="welcome"></p></div>'
  };

}]);
