UILogik

UILogik is a software framework designed to manage user interface logic and state in interactive applications. It emphasizes a declarative approach to UI construction and a clear separation between rendering and business logic. The framework aims to reduce complexity by promoting predictable state transitions, testability, and the composability of reusable UI components.

Core concepts in UILogik include state, actions, reducers or pure functions, selectors, and effects. It employs a unidirectional data flow in which user actions trigger events that update the central state, and the updated state drives rendering. UI components subscribe to slices of state and emit actions in response to user interactions or asynchronous events. The system supports reactive streams and can interoperate with existing UI frameworks through adapters or bindings.

Key features include a central store, middleware for handling side effects, support for asynchronous actions, optimistic updates, and undo/redo capabilities. The framework provides a rendering or binding layer to connect components to state, along with theming hooks and accessibility utilities. It also includes testing utilities for unit and integration testing.

Architecture and design philosophy emphasize modularity and framework-agnosticism. UILogik is intended to be mounted alongside established UI libraries, offering a consistent interface for managing UI logic while allowing developers to choose rendering technologies. A plugin or extension system enables adding capabilities such as advanced analytics, localization, or custom input handling, without compromising core guarantees of predictable state management.

Development and ecosystem: UILogik originated as an open-source project in the early 2020s and has attracted contributions from a diverse community. It is used in educational contexts and in prototype projects to illustrate UI architecture patterns and state management approaches.
