Jotai

Jotai is a React state management library by Poimandres: state is broken into minimal atoms that compose like building blocks, with dependency tracking handled automatically - only components actually using an atom re-render, curing the whole-tree re-render plague of React context. Derived state, localStorage persistence and extensions for Immer, XState and Query round out the ecosystem, covering everything from a simple useState replacement to enterprise TypeScript apps. MIT licensed.

1. Migrate from useState gently: one atom is one minimal state unit.
2. Compose atoms into derived state; rendering optimizes itself.
3. Add persistence, Immer, XState or other extensions as needed.

• Atomic state, freely composable
• Automatic dependency tracking, precise renders
• Rich extensions (persistence, Immer, XState)
