## What it is
Undux is a dead-simple, fully type-safe state management library for React, built on RxJS. It replaces Redux-style actions, reducers, and dispatchers with a minimal get/set store API and supports both React Hooks and higher-order component usage.

## Use cases
- manage shared state in a React app without Redux boilerplate
- get fully type-safe state updates in a TypeScript React project
- use a simple get/set store with React Hooks
- subscribe React components to reactive state changes
- replace Redux/Flux with a minimal state container
- share state across components without prop drilling

## When to choose
- you want minimal, type-safe state management with almost no boilerplate
- your app's state needs are simple and you find Redux overkill
- you prefer a get/set API over actions and reducers
- you want built-in React Hooks support

## When to avoid
- you need middleware ecosystems, devtools, or time-travel debugging like Redux offers
- you have complex state logic with many side effects and prefer reducers
- you need a library under very active development
- you want framework-agnostic state management outside React

## Facets
- artifact type: library
- maturity: maintenance
- function: state-management, frontend-framework
- domain: web-development, frontend, developer-tools
- platform: cross-platform
- tags: react, typescript, redux-alternative, flux, hooks, reactive-state, nodejs, web-server
