This document summarizes a presentation on building web applications with AngularJS. It introduces AngularJS as a client-side JavaScript framework that uses HTML enhanced with directives for building rich web apps. Core concepts covered include MVC pattern, two-way data binding, dependency injection, and separation of concerns. Demos illustrate data binding, controllers, filters, directives, views/routes, and animations. Built-in features and the AngularJS ecosystem are also discussed.

- 2. About Me Philipp Burgmer Senior Software Engineer / Consultant WeigleWilczek GmbH burgmer@w11k.com Focus: Frontend, Web Technologies
- 3. About Us WeigleWilczek / W11k Software Design, Development & Maintenance Consulting and Coaching Web Applications Eclipse RCP Java / JVM
- 4. Web Apps until now 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
- 5. Web Apps from now 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
- 6. What is AngularJS? HTML enhanced 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
- 7. Core Concepts Model View Controller Pattern Two Way Data-Binding Dependency Injection Modules Services Directives Filter Separation of Concerns Testable Code
- 8. 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)
- 9. Dependency Injection Java with Google 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 } }
- 10. Dependency Injection Java with Google 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);
- 11. Dependency Injection JavaScript with AngularJS 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 }; }

- 13. Dependency Injection JavaScript with AngularJS 1 // dependency management and di configuration 2 angular.module('myModule', ['moduleOfOtherLibrary']) 3 // no scopes, services are singletons by definition 4 .service('usefulService', ['$window', function(a) { 5 function somethingPrivate() { } 6 7 return function() { 8 somethingPrivate(); 9 a.close(); 10 11 }; }]

- 15. Dependency Injection Additional parameters and 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);
- 16. Directives extend HTML Tags, Attributes, CSS classes encapsulate DOM manipulations proceeded by AngularJS compiler

- 18. Views & Routes Deep linking 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>
- 19. Demo Small crud app (http://jsbin.com/exevex/14/edit?live) -> with own URL bar: local This Presentation
- 20. Animations new in Version 1.2 easy to use plain CSS Animations and Transitions CSS classes for 'enter', 'move' and 'leave' custom JS functions possible directives must support ng-animate ng-repeat ng-view ng-include ng-show ng-hide
- 21. Demo ng-repeat (http://jsbin.com/upedez/7/edit?live) ng-view (http://jsbin.com/ixapay/4/edit?live) Fancy stuff: bouncy balls (http://jsbin.com/uwiyer/21/edit?live)
- 22. Built-in Features Extensibility Embeddable Testable Code Templating Localization Validation REST support Async Code with Promises ...
- 23. Built-in Features Directives ng-click ng-class ng-show / ng-hide ng-include ng-view ng-pluralize ng-repeat ng-submit ... Filter currency date filter json limitTo lowercase number orderBy uppercase Services http location log q resource route timeout window ...
- 24. Eco System (http://www.gruntjs.com) Bower (http://www.bower.io) Bootstrap (http://www.git-scm.com) Task Runner / Build System Dependency Management for 3rd party libs Front-End Framework Styling & Layout (http://www.git-scm.com) (http://www.nodejs.org) (http://www.git-scm.com) CSS Extension Language Version Control System Runtime for Dev Tools / Backend Environment
- 25. Conclusion Clean separation of Frontend 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!
