20. MAIN CONCEPTS
21. INTEGRATION-ORIENTED • Rhino - Interaction with Java (APIs and objects) - Helma, Persevere, Narwhal, RingoJS, Sun Phobos... • JScript .Net - Interaction with MS .NET (APIs and objects) - IronJS, Node.NET
22. COMMON JAVASCRIPT • Ubiquity not only for ECMAScript • Server missing APIs • Web Applications 1.0 • Asynchronous & Synchronous • Working Groups: - CommonJS - WHATWG - W3C - ECMA TC39
23. ASYNC. EVENT-BASED • Browser Event-Loop on the Server • An Event Loop in one single thread • Cooperative («one at a time») with async. callbacks • Node.js (V8), SpiderNode, RhiNodeII, Node.NET
24. SINGLE vs MULTI THREADING One context per thread SINGLE • Low memory usage • Potentially handle lot of requests • Cooperative • Shared context • Use mostly one core MULTI • Vertical scalability (multi-core) • Thread-safety for concurrent access • Preemptive: Parallel code execution • Allow Synchronous APIs • Uses easily all available cores
25. DATABASE-DRIVEN • Document Store - CouchDB, MongoDB • Object Store - Wakanda • Push Store - APE
26. APIS
27. COMMONJS • Modules • Packages • Promises • System • Unit-Testing • Binary • File • JSGI • Stream http://wiki.commonjs.org/wiki/CommonJS
28. NODE ASYNC APIS • Buffer • Events • File • Net • OS • Process • Streams • Timers • . . . http://nodejs.org/docs/v0.5.5/api/
29. W3C / HTML5 & OTHER STANDARDS • Console • Blob, Blob URL* • DataView* • File / FileSystem • Modules* • Progress Events • Structured clones • Typed Arrays* • Web Sockets • Web Storage • Web Workers • XHR 2
30. PACKAGES & MODULES • github: CommonJS modules in forks (Persevere, Narwhal, RingoJS, ...) • NPM: Node Package Manager (3600+ packages) • CPM: CommonJS Package Manager (new) • PINF: Universal module loader http://wiki.commonjs.org/wiki/CommonJS
