## What it is
Zustand is a small, fast, and scalable state management library for React based on simplified flux principles, with a hook-based API and no provider boilerplate. It handles common React pitfalls like zombie children, concurrency, and context loss between mixed renderers.

## Use cases
- manage global state in a react app without boilerplate
- replace redux with a simpler hook-based store
- share state between react components without context providers
- create a store as a custom hook with actions and state
- selectively re-render components on state slices
- handle state in react concurrent mode safely

## When to choose
- you want minimal, unopinionated state management for React
- you need a tiny bundle size and hook-based API
- you want to avoid providers and boilerplate of redux or context
- you need reliable behavior with React concurrency and mixed renderers

## When to avoid
- you need a full state management ecosystem with devtools middleware, sagas, and strict conventions
- your app is not React-based
- you prefer normalized entity stores with heavy tooling like redux toolkit

## Facets
- artifact type: library
- maturity: stable
- function: state-management, frontend-framework
- domain: frontend, web-development
- platform: browser, cross-platform
- tags: react, hooks, flux, store, redux-alternative, nodejs
