$route

$routeProvider

$route

npm install angular-ui-router --save

angular.module('myApp', ['ui.router']);

ui-router

<!-- index.html -->
<body>
    <div ui-view></div>
    <!-- We'll also add some navigation: -->
    <a ui-sref="state1">State 1</a>
    <a ui-sref="state2">State 2</a>
</body>

ui-router

<!-- partials/state1.html -->
<h1>State 1</h1>
<hr/>
<a ui-sref="state1.list">Show List</a>
<div ui-view></div>

<!-- partials/state2.html -->
<h1>State 2</h1>
<hr/>
<a ui-sref="state2.list">Show List</a>
<div ui-view></div>

ui-router

 //
  // For any unmatched url, redirect to /state1
  $urlRouterProvider.otherwise("/state1");
  //
  // Now set up the states
  $stateProvider
    .state('state1', {
      url: "/state1",
      templateUrl: "partials/state1.html"
    })
    .state('state1.list', {
      url: "/list",
      templateUrl: "partials/state1.list.html",
      controller: function($scope) {
        $scope.items = ["A", "List", "Of", "Items"];

      controller: function($scope) {

      }
    });

ui-router

<!-- index.html -->
<body>
    <div ui-view="viewA"></div>
    <div ui-view="viewB"></div>
    <!-- Also a way to navigate -->
    <a ui-sref="route1">Route 1</a>
    <a ui-sref="route2">Route 2</a>
</body>

ui-router

myApp.config(function($stateProvider) {

Tasks

  • Create application with tag game,timer and calculator on separate views
  • Use multiple views for show statistic and apps

providers

1. app.config(() => {})
2. app.run(() => {})
3. directive's compile functions 
    (if they are found in the DOM)
4. app.controller((Services, Factories) => {})
5. directive's link functions 
    (again, if found)
app.config(($http) => {});
