RESThub 1.1 presentation

2. Full stackframework

3. Whatis RESThub ? Java Stack JavascriptStack

4. Don'tRepeatYourself

5. Keep It Simple, Stupid

6. Not reinventing the wheel ! Some rights reserved by vrogy

7. Java Stack

8. Java stack modules GenericRESTWebservice Tapestry 5 Integration Plugin Architecture Generic Middle classes Tooling - Testing Documentation

10. Java Middle stack Validator JSR 303 Bean validation SpringDBUnitintegration Hades 2 Generic DAO Generic Services and tests 3.5 JPA2 Persistenceengine Cross modules scanningfor JPA entities Embedded database 1.3

11. Generic classes @Named("bookingDao") public class JpaBookingDao extends GenericJpaResourceDao<Booking> implements BookingDao { ...} @Named("bookingService") public class BookingServiceImpl extends GenericResourceServiceImpl<Booking, BookingDao> implements BookingService { ...}

17. REST webservices JAX-RS REST Webservices OAuth2 basedsecurity Jersey 1.6 GenericwebservicesGeneric tests JSON Serialization Jackson 1.7 7.3 WADL explorer jQuery plugin Run/Debug web application

18. Generic REST Services How to… retrieve a persisted object in database ? @GET @Path("/{ref}") @Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON}) public Response getResource(@PathParam("ref") String ref) { T entity = this.service.findByRef(ref); if(entity == null) { return Response.status(Status.NOT_FOUND).build(); } return Response.ok(entity).build(); }

19. OAuth2

21. JSON serialization

22. Not so simple to manage (cyclic object graphs)

23. « BadgerFish » or « Mapped » strategy are not easy to use

24. We have chosen Jackson POJO serialization

25. Interesting features like parent/children bi–directional link support

27. Use case 1 : server based MVC Framework Clientside Stateless Browser Dynamicpages Session MVC Framework Webservices(optional) MVCframework Server side Middle Templateprocessing

28. Use case 2 : client MVC with RESThub JS Session Browser MVCframework Client side HTML5/JavaScript RIA Templateprocessing Staticfiles Dynamicdata RESTWebservices Static file(JS, HTML, CSS) Stateless Server side Middle

29. Why Java developpershate JS ? Contextloss, and no classes Scopes and closures No strongtyping Cross browser compatibility Damnit, it’s Web developpement !

30. But Web techno Rocks ! Concernsseparation Highlydynamic Productive and quick Apps are trendy and sexy

31. No restart needed !

32. Javascriptstack for RIA Webapps But why ? RIA vs Server sidepresentationframework So muchunused power on our desktop ! Competitorsalreadyprovideframework Allows… Use the latest web technologies consistently Reduce traffic and server load Reuse server-programming good practices

33. Javascriptstack Widgets JavaScript core library ui 1.8 1.4 Script loader andOptimizer Class support RESThub JS MVC

34. Script loading I wantmy imports ! define([ 'lib/resthub', 'routes', 'controllers/home' ], function() { ... });

35. Routing Only one « real » page Using the hash > no reload $.route('#/home', function() { ... }); $.route('#/home');

36. Classes We’reused to OOP, not prototype define(['lib/class'], function(Class) { returnClass.extend('MyClass', { attribute: 'some value', method: function() { } }); }); Static, instance, single inheritance

37. Controllers & templates Controller: presentationlogic define(['lib/controller'], function(Controller) { returnController.extend('HomeController', { template : 'views/home.html', init : function() { this.render({user:{name:'Tyler'}}); } }); }); Template: readable DOM fragment <p>Hello ${user.name} !</p>

38. Widgets Interactive enhanced GUI Buildyour GUI, as in Swing/SWT init: function() { this.render(); $('a.confirm', this.element) .click($.proxy(this, '_confirmHandler') .button({ label: i18n.buttons.confirm }); }

39. Repositories Connection to REST servers define(['lib/repository'], function(Repository) { returnRepository.extend('UserRepository', { root: 'api/users/', findByName: function(name, callback) { this._get(this.root + name, callback); } }); });

40. Bonus Local storage > client session Event bus > betweencontrollers I18n > like in Java Security > OAuth2 JSON > effective communication Console > like log4j …
