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

COMMON JAVASCRIPT
• Working Groups:
- CommonJS
- WHATWG
- W3C
- ECMA TC39

• L’ubiquité au delà d’ECMAScript

• HTML5 est aussi connu sous le nom de : “Web Applications 1.0”

• Asynchronous & Synchronous APIs

ASYNC. EVENT-BASED
Node.js like

• 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

SINGLE & MULTI THREADING
One context per thread

SINGLE MULTI
• Low memory usage • Vertical scalability (multi-core)
• Potentially handle lot of requests • Thread-safety for concurrent access
• Cooperative • Preemptive: Parallel code execution
• Shared context • Allow Synchronous APIs
• Use mostly one core • Uses easily all available cores

Notes:
- an event loop can generate some other threads
- multi-thread architectures can run event loops in some of their threads

DATABASE-DRIVEN
• Document Store
- CouchDB, MongoDB

• Key/value Store
- Riak

• Object Store
- Wakanda

• Push Store
- APE

COMMONJS

• Modules • Packages • Promises

• System • Binary • JSGI

• Unit-Testing • File • Stream

http://wiki.commonjs.org/wiki/CommonJS

NODE
ASYNC APIS

• Buffer • Net • Streams

• Events • OS • Timers

• File • Process • ...

http://nodejs.org/docs/v0.5.5/api/

W3C / HTML5 / ES.NEXT
& OTHER STANDARDS
• Console • Structured clones

• Blob, Blob URL* • Typed Arrays*

• DataView* • Web Sockets

• File / FileSystem • Web Storage, Indexed DB

• Modules* • Web Workers

• Progress Events • XHR 2

PACKAGES & MODULES

• github: CommonJS modules in projects (Persevere, Narwhal, RingoJS, ...)

• NPM: Node Package Manager (thousands packages)

• CPM: CommonJS Package Manager (new)

• PINF: Universal module loader
