SharedJS Core JS library

CommonJS Mocha testable shared JavaScript library. This project is a dependency for the following projects:

• SharedJS.Web
• SharedJS.App

Purpose of this PoC library

Share as many code as possible in both Web and Mobile JS applications. This PoC library is set up in such a way that e.g. the same business logic and state, but e.g. different persistency, audioplayer or Google analytics implementations can be applied in both web and app projects.

###Why a shared JS codebase

• Just like we use Titanium to develop apps for both iOS + Android, why not use JS to …
• Take away inconsistencies between mobile app and web app logic.
• Keep things DRY, why write something in JS twice?
• Reduce TCO. Cut costs for both initial development + AM

###Objectives

• Keep business logic in one place
• Unit test business logic once
• Leverage context specific technologies:
  • HTML5 BB Web App: It should be possible to use BB plugins like LayoutManager + Stickit
  • Ti Alloy App: It should be possible to use Alloy views and Alloy MV binding.
• Keep it very simple! With very little, and no exotic, dependencies.

###Setup insctructions Setting up this project would require the following:

$ npm install

####proxy shim Apart from that to load our dependencies via node require, we need a shim for Mocha testing. To achieve this, we made a very cheap shim leveraging the way node uses node_modules as a search path when searching for modules. For this reason in node_modules we create a custom proxy.js which serves as a proxy of its own for our local project utils/proxy.js module. We explicitly added this file to git while ignoring everything else inside the node_modules folder.

###Test instructions Either use the repository grunt tasks to test the library or use.

$ mocha
