Redirect index page if user is logged in AngularJS

Make sure to read comment under the answer. When I answered this question I didn't thought about unit tests and design. I was just demonstrating that what can be one of many ways to achieve the desired result

I think the best way to do it under controller or your app.config.run.In your case you should create another module to check for user login status. Inject user login status checking module to your app module.

Here is the link to the sample followed by the app.js code

var login = angular.module('myLoginCheck', [])  .factory('$logincheck', function () {    return function (userid) {      // Perform logical user logging. Check either       // by looking at cookies or make a call to server.      if (userid > 0) return true;      return false;    };  });var app = angular.module('myApp', ['myLoginCheck']);app.config(function ($routeProvider, $locationProvider) {    $routeProvider      .when('/publicurl', {})      .when('/loginurl', {})      .when('/unauthorize', {})      .otherwise({redirectTo: '/'});  })  .run(function ($logincheck, $location) {    //console.log("Into run mode");    console.log("Userid 5 is logged in: ", $logincheck(5));    console.log("Userid 0  logged in: ", $logincheck(0));    //now redirect to appropriate path based on login status    if ($logincheck(0)) {      //$location.path('/loginurl'); or              }    else {      //$location.path('/publicurl'); or     }  });app.controller('MainCtrl', function ($scope) {  $scope.name = 'World';});

I just did this, by making a dummy template and small controller for the / path which redirects as appropriate.

controllers.controller('loginController',                       ['$scope', '$location', '$cookies',                        function($scope, $location, $cookies) {    if (!!$cookies.user) {        console.log("already logged in!");        $location.path('/shows');    } else {        console.log("need to login!");        $location.path('/users');    }}]);var app = angular.module('app', ['ngRoute', 'ngCookies', 'controllers', 'services']);app.config(['$routeProvider',            function($routeProvider) {    $routeProvider.when('/users', {        templateUrl: "partial/users.html",        controller: 'userController'    });    $routeProvider.when('/shows', {        templateUrl: "partial/shows.html",        controller: 'showController'    });    $routeProvider.when('/', {        template: '',        controller: 'loginController'    });    $routeProvider.otherwise({        redirectTo: '/'    });}]);
