With Storybook for React Native you can design and develop individual React Native components without running your app.
This readme is for the 7.6.10 version, you can find the 6.5 docs here.
If you are migrating from 6.5 to 7.6 you can find the migration guide here
For more information about storybook visit: storybook.js.org
NOTE:
@storybook/react-native
requires atleast 7.6.10, if you install other storybook core packages they should be^7.6.10
or newer.
If you want to help out or are just curious then check out the project board to see the open issues.

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 init MyApp --template react-native-template-storybook
Run init to setup your project with all the dependencies and configuration files:
npx storybook@latest init
The only thing left to do is return Storybook's UI in your app entry point (such as App.tsx
) like this:
export { default } from './.storybook';
If you want to be able to swap easily between storybook and your app, have a look at this blog post
If you want to add everything yourself check out the the manual guide here.
We require the unstable_allowRequireContext transformer option to enable dynamic story imports based on the stories glob in main.ts
. We can also call the storybook generate function from the metro config to automatically generate the storybook.requires.ts
file when metro runs.
Expo
First create metro config file if you don't have it yet.
npx expo customize metro.config.js
Then set transformer.unstable_allowRequireContext
to true and add the generate call here.
// metro.config.js
const path = require('path');
const { getDefaultConfig } = require('expo/metro-config');
const { generate } = require('@storybook/react-native/scripts/generate');
generate({
configPath: path.resolve(__dirname, './.storybook'),
});
/** @type {import('expo/metro-config').MetroConfig} */
const config = getDefaultConfig(__dirname);
config.transformer.unstable_allowRequireContext = true;
config.resolver.sourceExts.push('mjs');
module.exports = config;
React native
const path = require('path');
const { generate } = require('@storybook/react-native/scripts/generate');
generate({
configPath: path.resolve(__dirname, './.storybook'),
});
module.exports = {
/* existing config */
transformer: {
unstable_allowRequireContext: true,
},
resolver: {
sourceExts: [...defaultConfig.resolver.sourceExts, 'mjs'],
},
};
In storybook we use a syntax called CSF that looks like this:
import type { Meta, StoryObj } from '@storybook/react';
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 .storybook
folder.
// .storybook/main.ts
import { StorybookConfig } from '@storybook/react-native';
const main: StorybookConfig = {
stories: ['../components/**/*.stories.?(ts|tsx|js|jsx)'],
addons: [],
};
export default main;
For stories you can add decorators and parameters on the default export or on a specifc 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 .storybook
folder.
// .storybook/preview.tsx
import type { Preview } from '@storybook/react';
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;
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 main.ts
addons list as follows:
// .storybook/main.ts
import { StorybookConfig } from '@storybook/react-native';
const main: StorybookConfig = {
// ... rest of config
addons: [
'@storybook/addon-ondevice-notes',
'@storybook/addon-ondevice-controls',
'@storybook/addon-ondevice-backgrounds',
'@storybook/addon-ondevice-actions',
],
};
export default main;
For details of each ondevice addon you can see the readme:
Storybook on react native is a normal React Native component that can be used or hidden anywhere in your RN application based on your own logic.
You can also create a separate app just for storybook that also works as a package for your visual components. Some have opted to toggle the storybook component by using a custom option in the react native developer menu.
You can pass these parameters to getStorybookUI call in your storybook entry point:
{
tabOpen: Number (0)
-- which tab should be open. -1 Sidebar, 0 Canvas, 1 Addons
initialSelection: string | Object (undefined)
-- initialize storybook with a specific story. eg: `mybutton--largebutton` or `{ kind: 'MyButton', name: 'LargeButton' }`
shouldDisableKeyboardAvoidingView: Boolean (false)
-- Disable KeyboardAvoidingView wrapping Storybook's view
keyboardAvoidingViewVerticalOffset: Number (0)
-- With shouldDisableKeyboardAvoidingView=true, this will set the keyboardverticaloffset (https://facebook.github.io/react-native/docs/keyboardavoidingview#keyboardverticaloffset) value for KeyboardAvoidingView wrapping Storybook's view
}
Storybook provides testing utilities that allow you to reuse your stories in external test environments, such as Jest. This way you can write unit tests easier and reuse the setup which is already done in Storybook, but in your unit tests. You can find more information about it in the portable stories section.
