Zustand

A minimalist 1.1KB state management library for React that implements Flux principles through a simple, hook-based API.

Zustand (German for state) is a lightweight store maintained by the Poimandres (pmndrs) collective. It bypasses the boilerplate of Redux and the re-render pitfalls of React Context: you define a store with a single create call and access it via hooks. For example: const useStore = create((set) => ({ count: 0, inc: () => set((s) => ({ count: s.count + 1 })) })). This library handles transient state updates efficiently and is utilized by engineering teams at Vercel and Shopify. It remains a top-tier choice for developers who value speed, small bundle sizes, and clean code architecture.
