pmndrs/zustand

Zustand — a small, fast, scalable state-management library for React. The modern default for "Redux is too much, Context is too little".

What it is

A TypeScript state-management library for React based on hooks. No providers needed, no Redux-style action types, no boilerplate. Define a store with create(), expose state + actions, consume via a selector hook. Authored by the pmndrs (poimandres) collective; tightly integrated with the broader React Three Fiber / Zustand / Jotai ecosystem.

Key features

• Zero-boilerplate store creation: create<T>((set) => ({...})).
• Selector-based subscriptions — components re-render only when selected state changes.
• Middleware system: persist, devtools, immer, subscribe-with-selector.
• TypeScript types bundled, strict mode-friendly.
• ~3KB gzipped.
• MIT-licensed.

Tech stack

• TypeScript primary.
• npm package: zustand.

When to reach for it

• You're a React team and want lighter state management than Redux.
• You want global state that doesn't require Context boilerplate.
• You want a TypeScript-first store with good types.

When not to reach for it

• You're already invested in Redux Toolkit and have working patterns.
• You need server-state — TanStack Query, SWR, Apollo fit that better.
• You need fine-grained reactivity — Jotai or Valtio (same org) may fit.

Maturity signal

58k stars, 2k forks, MIT, actively maintained. Open issues = 4. The pmndrs collective's reputation + low issue count signals mature maintenance.

Alternatives

• Redux Toolkit — when you want explicit action / reducer patterns.
• Jotai — atom-based reactivity from the same org.
• TanStack Query — for server state.
• React Context + useReducer — for simple cases.
