3. WHAT IS FAMO.US? Is it famous? In Taiwan, NO.
4. ABOUT 2 YEARS AGO HTML5DevConf 2012 http://www.slideshare.net/befamous/html5-devconf-oct-2012-tech-talk
5. Steve Newcomb - CEO Co-funder, Famo.us.
6. WHAT IS FAMO.US? • A framework for web application • New way to handle the HTML Elements • Simplify the DOM render in the browser • Solve the performance of DOM/CSS and JavaScript • Solve the difference in browsers • Easy to develop the web app
7. DEMO PLEASE http://famous-bird.herokuapp.com/
8. OLD “RENDER” WebCore in Webkit
9. RENDER ENGINE IN WEBKIT Simplified render parsing DOM tree

13. WHY FAMO.US ? • New “Render Tree” ( an abstract DOM ) • All about JavaScript, no HTML ( Yes, If you do not like to write HTML ) • Modifiers control everything • Very GOOD performance • A little bad semantic structure of DOM • Make sure the render result are all the same in the browsers
14. – Jeff Pope, Sencha. 「Easy to learn, easy to build, easy to maintain!」
15. HOW ABOUT FAMO.US • Easy to learn • Easy to build • Easy to maintain
16. CHALLENGE <div class="container"> <div class="animate cube" style="width: 100px; height: 100px; background-color: #3366ff;"> <span class="text">JSDC</span> </div> </div> .cube { animation-duration: 3s; animation-iteration-count: infinite; animation-name: rotate; } @keyframes rotate { from { transform: rotate(0deg); } to { transform: rotate(180deg); } } JSDC JSDC
17. IN FAMO.US var initialTime = Date.now(); /** * ( 180 * Math.PI / 180 ) / 3 */ var Modifier = new Modifier({ transform: function() { return Transform.rotate(0, Math.PI / 3 * (Date.now() - initialTime) % 3, 0); } }); var Surface = new Surface({ classes: [‘cube’], content: ‘JSDC’ }); JSDC JSDC
18. CHALLENGE <div class="container"> <div class="animate cube1" style="width: 100px; height: 100px; background-color: #3366ff; transform: rotateZ(60deg);"> <div class="animate cube2" style="width: 100px; height: 100px; background-color: #3366ff; transform: rotateZ(120deg);"> <div class="animate cube3" style="width: 100px; height: 100px; background-color: #3366ff; transform: rotateZ(240deg);"> <span class="text">JSDC</span> </div> </div> </div> </div> I’m a cube. I’m a cube. I’m a cube. JSDC $(‘.cube1’).on(‘click’, function(event) { $(this).css(‘transform’, ‘rotateZ(180deg)’); }); $(‘.cube3’).on(‘click’, function(event) { $(this).css(‘transform’, ‘rotateZ(120deg)’); }); I’m a cube. I’m a cube. I’m a cube. JSDC
19. IN FAMO.US var Modifier1 = new Modifier({ transform: Transform.rotate(0, Math.PI / 3, 0) }); var Surface1 = new Surface({ classes: [‘cube’], content: ‘JSDC’ }); Surface1.on(‘click’, function() { Modifier1.transformFrom(Transform.rotate(0, Math.PI, 0)); }); I’m a cube. I’m a cube. I’m a cube. JSDC I’m a cube. I’m a cube. I’m a cube. JSDC
20. CHALLENGE <div class="container"> <div class="animate cube1" style="width: 100px; height: 100px; background-color: #3366ff; transform: rotateZ(60deg);"> <span class="text">JSDC</span> </div> <div class="animate cube2" style="width: 100px; height: 100px; background-color: #3366ff; transform: rotateZ(120deg);"> <span class="text">JSDC</span> </div> </div> var $elem = $(‘.cube1’); $({deg: 0}).animate({deg: 120}, { duration: 2000, step: function(now) { $elem.css(‘transform’, ‘rotateZ(‘ + now + ‘deg)’); } }, function(event) { $(‘.cube2’).css(‘transform’, ‘rotateZ(180deg)’); }); JSDC JSDC JSDC JSDC
21. IN FAMO.US JSDC JSDC JSDC JSDC var Transitionable = new Transitionable([0, Math.PI / 3, 0]); var Modifier1 = new Modifier({ transform: Transitionable }); var Surface1 = new Surface({ classes: [‘cube’], content: ‘JSDC’ }); Transitionable.set( Transform.multiply(Transitionable.getFinal(), Transform.rotate(0, Math.PI * 2 / 3, 0)), 2000, function() { /* Rotate the Cube 2 */ } );
22. All JavaScript, NO HTML. (If you want)
23. RENDER TREE
24. http://en.wikipedia.org/wiki/File:Person-tree.jpg#mediaviewer/File:Person-tree.jpg
25. IN HTML WAY <div class="container"> <div class="animate cube" style="width: 100px; height: 100px; background-color: #3366ff; transform: rotateZ(60deg);"> <span class="text">JSDC</span> </div> </div> JSDC All in DOM
26. IN FAMO.US WAY var mainContext = Engine.createContext(); var mod = new Modifier({ size: [100, 100], transform: Transform.rotateZ(60 * Math.PI / 180) /* radians = degrees * (pi/180) */ }); var surf = new Surface({ classes: ['animate', 'cube'], content: '<span class="text">JSDC</span>', properties: { backgroundColor: ‘#3366ff' } }); var view = new View(); view.add(mod).add(surf); mainContext.add(view); JavaScript
27. IN FAMO.US WAY <body> </body> All in DOM
28. IN FAMO.US WAY <div class="famous-container"> <div class="famous-surface animate cube" style="width: 100px; height: 100px; -webkit-transform-origin: 0% 0%; -webkit-transform: matrix3d(0.5, 0.866025403784439, 0, 0, -0.866025403784439, 0.5, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); background-color: #3366ff;”> <span class="text">JSDC</span> </div> </div> JSDC After render
29. All JavaScript, NO HTML. (If you want)

31. RENDER TREE STRUCTURE Context Surface Context Modifier Surface Context Modifier ScrollView Surface 1 Surface 2
32. RENDER TREE PERFORMANCE • Keep DOM structure simple and clean • Less Reflows and Repaints in browser • Use EventsHandler to handle all the events • Calculate with JavaScript, paint and animate with CSS3 • Math Library • Provide a Physics Engine to do more simulate feature
33. RENDER TREE IN DOM Container Group Surfaces Context Modifier BODY
34. REFLOWS & REPAINTS • Very fast Reflows and Repaints • No Repaints, if not necessary
35. RENDER TREE IN ACTION Scroller Reflows Repaints
36. HOW TO FAMO.US?
37. COOL TOOLS • Famous/Browserify-Seed • Famous/generator-famous • Famous-Webpack-Seed
38. DEMO PLEASE
39. MODIFIER IS KING!
40. MODIFIERS • Modifier can modify EVERYTHING • Modifier can modify modifiers with Modifier Chain • Modifier can modify modifiers and modify his own children of modifier with Modifier Chain • Modifier and ModifierChain are little different between Famo.us and famo.us- Angular
41. MODIFIER IS ATTRIBUTE Container Group Modifier style=“transform: matrix(…);”
42. MODIFIER IS WAT !?
43. MODIFIER’S WAT! • Modifier MUST have a context, like Surface or etc • Modifier can NOT allocate • Modifier can only use the Transitionable or the object in roles • Modifier and StateModifier is MORE different from Famo.us ~0.2.x • Modifier in the render tree is an RenderNode just the same with others but “isModifier” property is “true” • RenderNode usually can get the Modifier, if use “.get()” method
44. DEMO PLEASE http://jsfiddle.net/arayi/gjdgbrfr/
45. EVENT HANDLER • Defined your own events • Use pipe/subscribe to transmit the events • Not depend on DOM • Multiple events
46. EVENT IN RENDER TREE EventsHandler EventsHandler Pipe Subscribe
47. DEMO PLEASE http://codepen.io/hinablue/pen/itpuf
48. VIEW AND WIDGET • Modifier + Surface • Modifier + View • Modifier + Widget • Modifier + ElementAllocator • View + View • View + Widget
49. CREATE YOUR OWN VIEW Container Group Surfaces Modifier
50. DEMO PLEASE http://famous.hinablue.me/SlideShow/
51. LIBRARY • Math • Transform • Transition • Physics Engine • Device Input • Element Allocator
52. DEMO PLEASE http://periodic.famo.us/?source=NL_062314
53. WAT, WAIT, AGAIN !?
54. INTERGRATIONS
55. FAMOUS-* • Famous-Angular • Famous-React
56. FAMOUS-ANGULAR • Not very good documentation (Actually, you can find more in source code) • You must follow the Famo.us render tree rules. • `<fa-` directive is not really compatible with others. • `fa-` Events and `ng-` Events can use together, but not recommend. • Customize directive in Famo.us is too hard to use if you are Angular beginner.
57. DEMO PLEASE http://goo.gl/5fMRKc
58. FAMOUS-REACT • Not stable for now
59. DEMO PLEASE http://famous.github.io/famous-react/
60. MORE INTEGRATION DEMOS • MeteorJS + famo.us • Famono • famous-views for Meteor • Pete Hunt, famous-react • Firebase with Famo.us • Backbone, source code from famous demo • [Video] famo.us + D3.js • [Video] Leap Motion
