Mobx React

mobx-react is a library that provides state bindings to connect React components to MobX observable state. It functions as a component state synchronizer, ensuring that user interface elements automatically re-render only when the specific observed data they consume changes.

The project enables a decoupled state architecture by moving business logic and domain state into standalone stores, separating data management from the React component tree. It facilitates global state distribution across deep component hierarchies using providers and context to avoid manual prop drilling.

The library covers a broad range of state management primitives, including observable collections, action-based updates, and computed state derivation. It provides UI integration helpers for both class and functional components, along with performance optimizations for component re-render precision and memory leak prevention during server-side rendering.

The project is implemented in TypeScript.

re-frame is a functional framework for building single-page applications in ClojureScript. It provides a centralized, immutable database that serves as the single source of truth for the entire application state, enforcing a strict unidirectional data flow where events trigger state transitions and subsequent view updates. The framework distinguishes itself through a reactive signal graph and an interceptor-based middleware pipeline. By treating application logic as a sequence of data-driven events and declarative side effects, it decouples business logic from the view layer. This architectur

MobX is a reactive state management library and fine-grained reactivity engine. It provides an observable data store that automatically triggers updates in the user interface when data structures change, functioning as a transparent functional reactive store to maintain a consistent source of truth. The system utilizes a dependency-graph mapping and proxy-based object observation to track data dependencies. This ensures that only the specific components dependent on changed data are updated, which reduces unnecessary re-renders and optimizes frontend performance. The library supports decoupl

React Redux is a set of official bindings and integration layers that connect a Redux global state container to a React user interface. It functions as a state synchronization library and a communication bridge, allowing components to read state and dispatch actions to a centralized store. The project decouples business logic from the view layer, ensuring that the user interface automatically updates whenever the underlying global state changes. It manages complex data flows by linking the UI to a central state container to share data across different components and screens. The library impl

Reagent is a framework for building web user interfaces using ClojureScript and React.js. It enables a functional programming approach to declarative UI design, where HTML structures and component hierarchies are defined using vector-based Hiccup syntax instead of JSX. The project differentiates itself through a reactive state management system based on atoms. It tracks which components dereference specific state atoms to trigger automatic re-renders and provides state cursors to isolate updates to specific paths of a larger state atom. It also includes utilities for wrapping native JavaScrip
