• Implements ComponentQuery

• Not a single component with a static id!


The SenchaCon app


The SenchaCon app

• Highly optimized custom components

• Reusability kept in mind throughout code base

• Code developed with minification in mind

• Minified with Sencha SDK Tools 2.0


Breaking the ice

• Develop individual views & models in their own sandbox

• Views should work independently

• One HTML file per view for testing

• Test fired events via Webkit console

• Allowed for us to divide and conquer


Pass #1

• Initial development done in Sencha touch 1.0

• Used MVC

• Router

• History

• Best practices for extending components

• Paved the way for the Sencha Touch 2.0 migration


Enter Sencha Touch 2!


Migrate to the new class system


Sencha Touch 2.0 migration

• Change the namespace to match the new MVC pattern

• Views

• Models

• Controllers

• Utilities


Quick MVC thoughts

• Controller is at the center

• Controller subscribes to events from the view

• Controller updates the model

• Model drives the view

Quick MVC thoughts

• Application extends Controller!

• Controllers can talk to the application via events or direct methods calls
