User:Alive/System Refactor Plan

System Refactor Plan

High level goals

• Modularization
• One system app for multiple devices
• Maintenance

Key features

• Swappable functionality
• Concentrated module responsibility
• Reduce startup time

Swappable functionality

• Each HW specific functionality should be easily removed/disabled from the current code base.
• Less module dependency - try not touch global variable.

If you need to ask someone else to work, ask the mediator instead of asking it directly.

 var MyModule = {
   show: function() {
     UtilityTray.hide(); // Sad
     Service.request('UtilityTray:hide'); // Better
   }
 };

Special Topics

• Statusbar destruction
