What problem does it solve?

Jotai provides a flexible primitive-based approach to React state management, and this skill helps teams design robust atom structures, derive performant state, and optimize re-renders with best practices.

Core Features & Use Cases

• Atom patterns: primitive, derived, write-only actions, and atom families.
• Performance optimization: granular subscriptions, derived selectors, and focused atoms.
• Usage with TS & tooling: type-safe atoms, patterns for large apps, and SSR support.
• Use Case Example: Build application state with atoms to model domain concepts, and progressively optimize with splitAtom and focusAtom.

Quick Start

Install jotai and jotai/utils, create a primitive atom, read/write with useAtom, and progressively adopt derived/split atoms for fine-grained updates.
