Introduction

Welcome to the Jotai v2 documentation! Jotai's atomic approach to global React state management scales from a simple useState replacement to an enterprise application with complex requirements.

Features

• Minimal core API (2kb)
• Many utilities and extensions
• TypeScript oriented
• Works with Next.js, Gatsby, Remix, and React Native
• React Fast Refresh with SWC and Babel plugins

Core

Jotai has a very minimal API, exposing only a few exports from the main jotai bundle. They are split into four categories below.

Utilities

Jotai also includes a jotai/utils bundle with a variety of extra utility functions. One example is atomWithStorage, which includes localStorage persistence and cross browser tab synchronization.

Extensions

Jotai has separate bundles for many official extensions including atomWithQuery for React Query and atomWithMachine for XState, among many others.

Tools

There are also SWC and Babel compiler plugins for React Fast Refresh support and debugging labels. This creates the best developer experience when using Jotai with a React framework such as Next.js or Gatsby.
