---title: Babeldescription: This doc describes the `jotai/babel` bundle.nav: 2.04---
## plugin-debug-label
Jotai is based on object references and not keys (like Recoil). This means there's no identifier for atoms. To identify atoms, it's possible to add a `debugLabel` to an atom, which can be found in React devtools.
However, this can quickly become cumbersome to add a `debugLabel` to every atom.
This `babel` plugin adds a `debugLabel` to every atom, based on its identifer.
The plugin transforms this code:
```tsexport const countAtom = atom(0)```
Into:
```tsexport const countAtom = atom(0)countAtom.debugLabel = 'countAtom'```
Default exports are also handled, based on the file naming:
```ts// countAtom.tsexport default atom(0)```
Which transform into:
```ts// countAtom.tsconst countAtom = atom(0)countAtom.debugLabel = 'countAtom'export default countAtom```
## Usage
With a `babel` configuration file:
```json{ "plugins": ["jotai/babel/plugin-debug-label"]}```
Examples can be found below.
## plugin-react-refresh
This plugin adds support for React Refresh for Jotai atoms. This makes sure that state isn't reset, when developing using React Refresh.
## Usage
With a `babel` configuration file:
```json{ "plugins": ["jotai/babel/plugin-react-refresh"]}```
Examples can be found below.
## preset
Jotai ships with a `babel` containing the plugins created for Jotai.
## Usage
With a `babel` configuration file:
```json{ "presets": ["jotai/babel/preset"]}```
