  Web Apps untilnow GWT UI in Java / XML hard to use JS libs / scatters ui logic "Java World" instead of "Web World" JSF UI on Server a lot HTTP requests just to update UI hard to use JS libs / scatters ui logic Flex based on Flash Adobe discontinues developement MXML and ActionScript instead of HTML and JavaScript
• 4.
  Web Apps fromnow on Frontend runs completely in the browser Stateful UI, stateless server Server delivers static resources Server delivers dynamic data HTML, CSS and JavaScript as UI Toolkit
• 5.
  What is AngularJS? HTMLenhanced for web apps! angularjs.com client / browser JS framework rich browser applications brings core frontend concepts and features to the browser extends html instead of abstracting or wrapping it lets you extend html to fit your needs

  Core Concepts Model ViewController Pattern Two Way Data-Binding Dependency Injection Modules Services Directives Filter Separation of Concerns Testable Code

  Demo Two Way Data-Binding(http://jsbin.com/atufut/14/edit?live) Add Logic with a Controller (http://jsbin.com/igoxuj/15/edit?live) Format Values with Filters (http://jsbin.com/esavog/13/edit?live)

  Dependency Injection Java withGoogle Guice 1 // no dependency management 2 public class MyModule extends AbstractModule { 3 protected void configure() { 4 // bind with interface 5 bind(Service.class).to(ServiceImpl.class); 6 // bind with scope 7 bind(OtherService.class).in(Singleton.class); 8 // bind with alias 9 bindConstant().annotatedWith(Names.named("port")).to(8080); 10 11 } }
• 9.
  Dependency Injection Java withGoogle Guice 1 @Singleton 2 public class ServiceImpl { 3 @Inject 4 public ServiceImpl(final OtherService otherService) { } 5 } 1 // manual or by configured framework 2 final Injector injector = Guice.createInjector(new MyModule()); 3 final Service service = injector.getInstance(Service.class);
• 10.
  Dependency Injection JavaScript withAngularJS 1 // dependency management and di configuration 2 angular.module('myModule', ['moduleOfOtherLibrary']) 3 // no scopes, services are singletons by definition 4 .service('usefulService', function($window) { 5 function somethingPrivate() { } 6 7 return function() { 8 somethingPrivate(); 9 $window.close(); 10 11 }; }

  Dependency Injection JavaScript withAngularJS 1 var service = function(a) { 2 return function() { 3 4 a.close(); } 5 } 6 service.$inject = ['$window']; 7 8 angular.module('myModule', ['moduleOfOtherLibrary']) 9 .service('usefulService', service);
• 14.
  Dependency Injection Additional parametersand overridden DI values 1 // get the injector via static call 2 var $injector = angular.injector(); 3 // or via injection 4 function($injector) { } 1 var functionA = function(serviceA) { }; 2 $inject.invoke(functionA); 3 4 var functionB = function(serviceA, nonDIValue) { }; 5 var locals = { nonDIValue: 1 }; 6 $inject.invoke(functionB, locals);

  Directives extend HTML Tags, Attributes,CSS classes encapsulate DOM manipulations proceeded by AngularJS compiler

  Demo Blink on SteroidsSpeed (http://jsbin.com/ekevip/41/edit?live) New Tags with Directives (http://jsbin.com/onacoh/11/edit?live)
• 17.
  Views & Routes Deeplinking Partial Views / Templating 1 angular.module('route.something').config(function ($routeProvider) { 2 $routeProvider.when('/something/:id/', { 3 templateUrl : "route/something.tpl.html", 4 controller : 'SomethingCtrl' 5 }) 6 }); 1 angular.module('myApp').config(function ($routeProvider) { 2 $routeProvider.otherwise({ 3 redirectTo: '/home' 4 }); 1 <div class="header">...<&div> 2 <div class="content"> 3 <div ng-view></div> 4 </div> 5 <div class="footer">...<&div>

  Conclusion Clean separation ofFrontend and Backend Features like DI, MVC and DataBinding in the browser Seamless integration with other frameworks Lets you use all the cool new Web / JS tools Easy to learn Documentation with a lot of runnable examples Large community and fast growing eco system powered and used by Google Try it!
