Storybook for React Native

A new docs site is being built for Storybook for React Native, you can find it at https://storybookjs.github.io/react-native/docs/intro/.

Important This readme is for v10, for v9 docs see the v9.1 docs.

With Storybook for React Native you can design and develop individual React Native components without running your app.

If you are migrating from 9 to 10 you can find the migration guide here

For more information about storybook visit: storybook.js.org

Note Make sure you align your storybook dependencies to the same major version or you will see broken behaviour.

Getting Started

New project

There is some project boilerplate with @storybook/react-native and @storybook/addon-react-native-web both already configured with a simple example.

For Expo you can use this template with the following command

# With NPM
npx create-expo-app --template expo-template-storybook AwesomeStorybook

For React Native CLI you can use this template

npx @react-native-community/cli init MyApp --template react-native-template-storybook

Existing project

Run init to setup your project with all the dependencies and configuration files:

npm create storybook@latest

Then wrap your bundler config with the withStorybook function. It auto-detects Metro vs Re.Pack and handles everything — entry-point swapping, story generation, and optional WebSocket setup.

// metro.config.js
const { getDefaultConfig } = require('expo/metro-config');
const { withStorybook } = require('@storybook/react-native/withStorybook');

const config = getDefaultConfig(__dirname);

module.exports = withStorybook(config);

No changes to App.tsx are needed. Set STORYBOOK_ENABLED=true and run:

STORYBOOK_ENABLED=true expo start

The wrapper automatically swaps your app's entry point with Storybook's entry point. When the variable is not set, your app runs normally with zero Storybook code in the bundle.

If you want to add everything yourself check out the manual setup guide.

Reanimated setup

Make sure you have react-native-reanimated in your project and the plugin setup in your babel config.

// babel.config.js
plugins: ['react-native-reanimated/plugin'],

Re.Pack setup

For projects using Re.Pack (Rspack/Webpack) instead of Metro, see the full Re.Pack Setup guide. You can also reference the RepackStorybookStarter project.

Expo router specific setup

For Expo Router projects, you can either use entry-point swapping (recommended) or create a dedicated Storybook route.

See the full Expo Router Setup guide for details.

Writing stories

In Storybook we use a syntax called CSF that looks like this:

import type { Meta, StoryObj } from '@storybook/react-native';
import { MyButton } from './Button';

const meta = {
  component: MyButton,
} satisfies Meta<typeof MyButton>;

export default meta;

type Story = StoryObj<typeof meta>;

export const Basic: Story = {
  args: {
    text: 'Hello World',
    color: 'purple',
  },
};

You should configure the path to your story files in the main.ts config file from the .rnstorybook folder.

// .rnstorybook/main.ts
import type { StorybookConfig } from '@storybook/react-native';

const main: StorybookConfig = {
  stories: ['../components/**/*.stories.?(ts|tsx|js|jsx)'],
  deviceAddons: ['@storybook/addon-ondevice-controls', '@storybook/addon-ondevice-actions'],
};

export default main;

Decorators and Parameters

For stories you can add decorators and parameters on the default export or on a specific story.

import type { Meta } from '@storybook/react';
import { Button } from './Button';

const meta = {
  title: 'Button',
  component: Button,
  decorators: [
    (Story) => (
      <View style={{ alignItems: 'center', justifyContent: 'center', flex: 1 }}>
        <Story />
      </View>
    ),
  ],
  parameters: {
    backgrounds: {
      values: [
        { name: 'red', value: '#f00' },
        { name: 'green', value: '#0f0' },
        { name: 'blue', value: '#00f' },
      ],
    },
  },
} satisfies Meta<typeof Button>;

export default meta;

For global decorators and parameters, you can add them to preview.tsx inside your .rnstorybook folder.

// .rnstorybook/preview.tsx
import type { Preview } from '@storybook/react-native';
import { withBackgrounds } from '@storybook/addon-ondevice-backgrounds';

const preview: Preview = {
  decorators: [
    withBackgrounds,
    (Story) => (
      <View style={{ flex: 1, color: 'blue' }}>
        <Story />
      </View>
    ),
  ],
  parameters: {
    backgrounds: {
      default: 'plain',
      values: [
        { name: 'plain', value: 'white' },
        { name: 'warm', value: 'hotpink' },
        { name: 'cool', value: 'deepskyblue' },
      ],
    },
  },
};

export default preview;

Addons

The cli will install some basic addons for you such as controls and actions. Ondevice addons are addons that can render with the device ui that you see on the phone.

Currently, the addons available are:

• @storybook/addon-ondevice-controls: adjust your components props in realtime
• @storybook/addon-ondevice-actions: mock onPress calls with actions that will log information in the actions tab
• @storybook/addon-ondevice-notes: Add some Markdown to your stories to help document their usage
• @storybook/addon-ondevice-backgrounds: change the background of storybook to compare the look of your component against different backgrounds

Install each one you want to use and add them to the deviceAddons list in your main.ts:

// .rnstorybook/main.ts
import type { StorybookConfig } from '@storybook/react-native';

const main: StorybookConfig = {
  // ... rest of config
  deviceAddons: [
    '@storybook/addon-ondevice-notes',
    '@storybook/addon-ondevice-controls',
    '@storybook/addon-ondevice-backgrounds',
    '@storybook/addon-ondevice-actions',
  ],
};

export default main;

Note deviceAddons ensures on-device addons are only loaded at runtime on the device, avoiding errors during server-side operations. .rnstorybook does not read addons.

Using the addons in your story

For details of each ondevice addon you can see the readme:

• actions
• backgrounds
• controls
• notes

Hide/Show storybook

Starting with v10.4, entry-point swapping is the default setup. Your existing in-app integration setup continues to work and is fully supported, but entry-point swapping is the recommended approach for new projects.

Entry-point swapping (recommended, v10.4+)

When using the bundler-agnostic withStorybook wrapper, set STORYBOOK_ENABLED=true to run Storybook. The wrapper swaps your app's entry point with Storybook's entry point automatically. When the variable is not set, your app runs normally with zero Storybook code in the bundle.

{
  "scripts": {
    "storybook": "STORYBOOK_ENABLED=true expo start",
    "storybook:ios": "STORYBOOK_ENABLED=true expo start --ios"
  }
}

Expo Router

Create a dedicated route for Storybook:

// app/storybook.tsx
export { default } from '../.rnstorybook';

Then navigate to /storybook in your app to view stories.

In-app integration (fully supported)

You can also import Storybook directly in your App.tsx. This approach continues to work and is fully supported:

import StorybookUI from './.rnstorybook';
import { MyApp } from './MyApp';

const isStorybook = process.env.EXPO_PUBLIC_STORYBOOK_ENABLED === 'true';

export default function App() {
  return isStorybook ? <StorybookUI /> : <MyApp />;
}

withStorybook wrapper

withStorybook is a bundler-agnostic wrapper that configures your project for Storybook. It auto-detects whether you're using Metro or Re.Pack and handles entry-point swapping, story generation, and WebSocket setup.

// metro.config.js
const { getDefaultConfig } = require('expo/metro-config');
const { withStorybook } = require('@storybook/react-native/withStorybook');

const defaultConfig = getDefaultConfig(__dirname);

module.exports = withStorybook(defaultConfig);

When STORYBOOK_ENABLED=true is set, the wrapper activates. When it's not set, the wrapper is a no-op and your app runs normally.

Options

Options can be passed as a second argument. Most settings can also be controlled via environment variables (see Environment Variables).

configPath

Type: string, default: path.resolve(process.cwd(), './.rnstorybook')

The location of your Storybook configuration directory, which includes main.ts and other project-related files.

useJs

Type: boolean, default: false

Generates the .rnstorybook/storybook.requires file in JavaScript instead of TypeScript.

docTools

Type: boolean, default: true

Whether to include doc tools in the storybook.requires file. Doc tools provide additional documentation features and work with babel-plugin-react-docgen-typescript.

liteMode

Type: boolean, default: false

Whether to use lite mode for Storybook. In lite mode, the default Storybook UI is mocked out so you don't need to install all its dependencies like react-native-reanimated. This is useful for reducing bundle size and dependencies. Use this when using @storybook/react-native-ui-lite instead of @storybook/react-native-ui. Note: STORYBOOK_DISABLE_UI=true is equivalent to onDeviceUI: false, not liteMode: true.

experimental_mcp

Type: boolean, default: false

Enables an experimental MCP (Model Context Protocol) server for AI tooling to query Storybook documentation and component/story metadata.

The MCP server is available at the /mcp endpoint on the Storybook channel server. Configure your MCP client via its settings UI, or use:

npx mcp-add --type http --url "http://localhost:7007/mcp" --scope project
