State of the art: Server-Side JavaScript - WebWorkersCamp IV - Open World Forum 2011
8 likes5,009 views
This document discusses the history and state of server-side JavaScript. It began in 1995 with LiveScript/JavaScript in browsers. In 2009, Node.js popularized an event-driven, non-blocking I/O model for servers using JavaScript. Since then many frameworks have adopted this approach, including RingoJS, Narwhal, and others. Benchmarks show Node.js has comparable or better performance than traditional server-side frameworks. Key concepts are its integration with databases, common APIs across browsers and servers, and an asynchronous event-based architecture using one thread and shared context.

- 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
- 25. SINGLE vs 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
- 26. DATABASE-DRIVEN • Document Store - CouchDB, MongoDB • Object Store - Wakanda • Push Store - APE
