Deft JS 增強了 Ext JS 和 Sencha Touch 的 API，提供額外的構建塊用以支持大的開發團隊快速開發企業級應用，利用最佳實踐和良好的模式實現工業化應用。

Goals

• Flexibility

  • Coordinates dynamic assembly of object dependencies based on a configurable IoC container.
  </ul> </li>
  • Approachability

    • Builds on familiar Ext JS API syntax conventions for ‘pay-as-you-go’ complexity.
    </ul> </li>
    • Simplicity

      • Eliminates boilerplate code in favor of the simplest expression of developer intent.
      </ul> </li>
      • Testability

        • Promotes loose coupling through class annotation driven dependency injection.
        </ul> </li>
        • Extensibility

          • Leverages the advanced class system provided by Ext JS and Sencha Touch.
          </ul> </li>
          • Reusability

            • Enables business layer code reuse between Ext JS and Sencha Touch applications.
            </ul> </li> </ul>

            Features

            IoC Container

            • Provides class annotation-driven dependency injection.
            • Maps dependencies by user-defined identifiers.
            • Resolves dependencies by class instance, factory function or value.
            • Supports singleton and prototype resolution of class instance and factory function dependencies.
            • Offers eager and lazy instantiation of dependencies.
            • Injects dependencies into Ext JS class configs and properties before the class constructor is executed.
            </ul>

            MVC with ViewControllers

            • Provides class annotation-driven association between a given view and its ViewController.
            • Clarifies the role of the controller - i.e. controlling a view and delegating work to injected business services (service classes, Stores, etc.).
            • Supports multiple independent instances of a given view, each with their own ViewController instance.
            • Reduces memory usage by automatically creating and destroying view controllers in tandem with their associated views.
            • Supports concise configuration for referencing view components and registering event listeners with view controller methods.
            • Integrates with the view destruction lifecycle to allow the view controller to potentially cancel removal and destruction.
            • Simplifies clean-up by automatically removing view and view component references and event listeners.
            </ul>
