UI Framework Lazy Controller Instantiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interface frameworks face inefficiencies due to the need for initializing UI components at load time, which can lead to slow page loading, increased memory usage, and code complexity, especially when not all components are needed immediately.
Innovation Solution
A UI framework that instantiates controllers only upon the first occurrence of an event, allowing for optional controller specification, automatic instantiation, and caching, with attributes defining module loading and removal, enabling declarative setup and handling of user interactions without initial creation or initialization at page load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UI components are initialized at load time, then the UI framework can handle user interactions, but the page loads slowly and uses excessive memory
Solution Approach 1:
The patent applies preliminary action by pre-defining controller declarations in the markup language and preparing the framework structure, but delaying the actual instantiation of controllers until events occur. This allows the UI framework to be ready to handle interactions without actually creating the heavy controller objects until needed, thus resolving the contradiction between having UI capability ready and avoiding slow load times.
Solution Approach 2:
The patent implements dynamics by making controller instantiation dynamic rather than static. Controllers are created on-demand based on event occurrence and cached for future use, rather than being created upfront. This dynamic approach allows the system to adapt its resource usage to actual user interaction patterns, improving load time while maintaining reliability.

If UI components are initialized at load time, then the UI framework can handle user interactions, but memory usage increases for components that may not be needed

3Reliability
If code is added to set up elements, create objects and listen for events, then the UI framework can handle user interactions, but the page size increases and code readability decreases
Solution Approach 1:
The patent extracts the controller creation and event listening logic from the markup language and HTML code, placing it in a separate UI framework layer. The markup only needs simple controller declarations, while the complex instantiation and event handling logic is handled automatically by the framework's dispatcher, thus reducing code complexity and improving readability.
Solution Approach 2:
The patent implements self-service by enabling the UI framework to automatically instantiate controllers and set up event listeners based on declarations in the markup language. The framework's dispatcher automatically detects events and creates appropriate controllers without requiring manual code setup, reducing the amount of code needed and improving readability.

AI summary
Systems, methods and computer readable media for user interface frameworks are disclosed. In some implementations, the method can include detecting, at a dispatcher within a user interface framework, an event emitted from a user interface element contained within a document object model node associated with a controller. The method can also include requesting a module associated with the controller and instantiating the controller. The method can further include providing the event to the controller.
