5. 5 OCT 2012 DEVCON5 HTML5 Summit 6 Ways JavaScript is Revolutionizing the Client/Server Relationship 6 ways JavaScript is Revolutionizing the Client/Server Relationship •Device Access Within the Browser •Client Side Processing w/ Background Threads •Device Detection and Descriptors / Adaptive Frameworks •HTML5 Connectivity Revolution and HTTP 2.0 •Single Runtime, Shared Syntax •Embedded JavaScript 5 Wednesday, November 28, 12
6. 5 OCT 2012 DEVCON5 HTML5 Summit 6 Ways JavaScript is Revolutionizing the Client/Server Relationship #1 Device Access within the Browser •Adobe Cordova (phoneGap) •Device API is now defunct. •getUserMedia/Stream API (no native IE support ... yet?) •GeoLocation API broad support (except IE8) •Device Orientation, Device Motion, (poorly supported / hacky) 6 The Client Gets Smarter. JavaScript Device APIs continue to evolve, allowing more access to device hardware, services and applications such as the camera, microphone, system sensors, native address books, calendars and native messaging applications.

12. 5 OCT 2012 DEVCON5 HTML5 Summit 6 Ways JavaScript is Revolutionizing the Client/Server Relationship #2: Client-Side Background Threads •Browser runs a single threaded, event loop • Dedicated Web Workers • Shared Web Workers •Async Programming Models, Reactionary Systems •Interpreters are Maturing (V8) 12 The Client Gets More Powerful. Web Workers API enables background threads in the browser, making heavy computations realistic. Wednesday, November 28, 12

27. 5 OCT 2012 DEVCON5 HTML5 Summit 6 Ways JavaScript is Revolutionizing the Client/Server Relationship #5: Single Language, Shared Syntax •Node Streams - IO as it should be • Linux Pipes • Modular • Different Types of Streams •Browserify - Build tool to Normalize APIs between Client/ Server • node-browserify - adds require() • http-browserify - adds http() •DomNode - wrap common I/O bound APIs in node style stream •Browser-stream - open pipable streams to and from the browser, with Socket.io 26 Node.js has enabled the same language, single runtime. But, the paradigms are still quite different. Next steps are shared APIs. Wednesday, November 28, 12

29. 5 OCT 2012 DEVCON5 HTML5 Summit 6 Ways JavaScript is Revolutionizing the Client/Server Relationship #6 Embedded JavaScript •more and more JavaScript Ubiquity •JavaScript Arduino Wrappers • Noduino • Johnny Five •Server moves to the Client • Beaglebone (Angstrom Linux) • Bonescript •Mongoose ORM • Mongo JavaScript CLI •node-ar-drone 28 There is a barrier of entry to learning SQL, C and C++, and Linux. JavaScript is opening new worlds for Developers. Not to mention, the server is now on the client. Wednesday, November 28, 12
