---title: Zustanddescription: This doc describes `jotai/zustand` bundle.nav: 4.06---
Jotai's state resides in React, but sometimes it would be niceto interact with the world outside React.
Zustand provides a store interface that can be used to hold some valuesand sync with atoms in Jotai.
This only uses the vanilla api of zustand.
## Install
You have to install `zustand` to access this bundle and its functions.
```npm install zustand# oryarn add zustand```
## atomWithStore
`atomWithStore` creates a new atom with zustand store.It's two-way binding and you can change the value from both ends.
```jsimport { useAtom } from 'jotai'import { atomWithStore } from 'jotai/zustand'import create from 'zustand/vanilla'
const store = create(() => ({ count: 0 }))const stateAtom = atomWithStore(store)const Counter: React.FC = () => { const [state, setState] = useAtom(stateAtom) return ( <> count: {state.count} <button onClick={() => setState((prev) => ({ ...prev, count: prev.count + 1 }))}> button </button> </> )}```
