Scalable JavaScript Application Example

This application architecture is base on this:

1. Andrew Dupont (Gowalla, Prototype.js, S2) Maintainable JavaScript http://channel9.msdn.com/Events/MIX/MIX11/EXT23
2. Nicholas Zakas (Yahoo!, YUI, YUI Test) Writing Maintainable JavaScript http://www.yuiblog.com/blog/2007/05/25/video-zakas/ Slides: http://www.slideshare.net/nzakas/maintainable-javascript-2011 http://www.slideshare.net/nzakas/maintainable-javascript-1071179
3. Scalable JavaScript Application Architecture http://developer.yahoo.com/yui/theater/video.php?v=zakas-architecture

The architecture of this application is described at Yandex.Subbotnik in Yekaterinburg

Depends

• LMD v1.3.0+ (https://github.com/azproduction/lmd) npm install lmd -g - required for build
• jQuery or Zepto.js - required for core modules (see index.html)

Build and run the example

1. cd build && make
2. open index.html

Build makes only js files

Running tests

1. cd test && make
2. open test/index.html

Changelog

v2.0

• Modules as all application architecture are greatly simplified
• This app is now depend on LMD so all modules are synchronous
• Added build system based on LMD (https://github.com/azproduction/lmd)
• Core is finally splitted on 4 logical parts: Core, EventManager, Sandbox and Template engine
• ModuleManager, loader and $script.js are wiped
• Part of ModuleManager logic is moved to Core
• All modules are loaded on startup (using lmd) so we no longer need a heavy loaders and $script.js
• All application modules (not lib modules) are totally sandboxed (cant require at all)
• Simple acl wildcards support listen:* and * but not listen:ololo:*

v2.1 (not compatable with v2.0)

• SJSA no longer depend on jQuery nor Zepto
• Sandbox#bind and Sandbox#trigger now accepts multiply event names
• Sandbox#getBox now returns HTMLElement instead of jQuery/Zepto instance
• Core.getBox uses getElementById instead of jQuery/Zepto selector
• Sandbox#getTemplate now accept elementId instead of selector (all templates should be marked with id)
• app descriptor can content list of safe modules (can require other modules) see app/modules/Logger.js for example
• EventManager totally refactored see test/units/EventManagerTest.js for details
