Storybook for React Native tutorial

Set up Storybook in your development environment

Storybook runs alongside your app in development mode. It helps you build UI components isolated from the business logic and context of your app. This edition of the Intro to Storybook tutorial is for React Native; other editions exist for React, Vue, Angular, Svelte and Ember.

Storybook and your app

Set Up React Native Storybook

We’ll need to follow a few steps to get the build process set up in your environment. To start with, we want to use Expo to set up our build system, and enable Storybook and Jest testing in our created app.

Before diving into the tutorial, take into account the following considerations:

  • All the code was intended for the Android platform, if you want to use IOS, some components might need to be updated in order to work properly.

  • You'll need a working simulator or a physical device correctly set up to maximize your experience, react-native docs has more detailed instructions on how to achieve this.

  • Throughout this tutorial, yarn will be used. Should you want to use npm, select the appropriate option when you're initializing the app and replace all subsequent commands with npm.

With that out of the way, let’s run the following commands:

# Create our application:
expo init --template tabs@sdk-36 taskbox

cd taskbox

# Add Storybook:
npx -p @storybook/cli sb init --type react_native

During Storybook's install process, you'll be prompted to install react-native-server, do so as this package will help out immensely throughout the tutorial.

Set Up Jest with React Native

We have two out of three modalities configured in our app, but we still need one, we need to set up Jest to enable testing.

Create a new folder called __mocks__ and inside add a new file globalMock.js with the following:

jest.mock('global', () => ({,
  WebSocket: function WebSocket() {},

Update the jest field in package.json:

"jest": {
    "preset": "jest-expo",
    "transformIgnorePatterns": [
    "setupFilesAfterEnv": [

Now we can quickly check that the various environments of our application are working properly:

# Run the test runner (Jest) in a terminal:
yarn test

# Start the component explorer on port 7007:
yarn storybook

# Run the frontend app proper on port 19002:
yarn web

3 modalities

Checking our Storybook at this point, you might see that there's no stories displayed. That's ok, we'll take care of it shortly, for now, let's continue working on getting our application properly set up.

Depending on what part of the app you’re working on, you may want to run one or more of these simultaneously. Since our current focus is creating a single UI component, we’ll stick with running Storybook.

Reuse CSS

Taskbox reuses design elements from the GraphQL and React Tutorial example app, so we won’t need to write CSS in this tutorial. Contrary to the other tutorials, we wont copy over the compiled CSS, as React Native handles styling in a whole different way, but instead create a new file constants/globalStyles.js and add the following:

import { StyleSheet } from 'react-native';
export const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    width: '100%',
  TaskBox: {
    flex: 1,
    color: '#333',
    fontSize: 16,
    backgroundColor: '#26c6da',
  CheckBox: {
    borderColor: '#26c6da',
    borderStyle: 'solid',
    borderWidth: 2,
    borderRadius: 1,
    backgroundColor: 'transparent',
    height: 18,
    width: 18,
  GlowCheckbox: {
    borderColor: '#eee',
    borderStyle: 'solid',
    borderWidth: 2,
    borderRadius: 1,
    backgroundColor: '#eee',
    color: 'transparent',
    height: 20,
    width: 20,
  GlowText: {
    backgroundColor: '#eee',
    color: 'transparent',
  ListItem: {
    flexDirection: 'row',
    flexWrap: 'nowrap',

    lineHeight: 20,
    fontStyle: 'normal',
  ListItemInputTaskArchived: {
    color: '#aaa',

    height: 'auto',
    textAlign: 'center',
  PageListsShow: {
    minHeight: '100vh',
    backgroundColor: 'white',
  PageListsShowhead: {
    backgroundColor: '#d3edf4',
    paddingTop: 24,
    paddingBottom: 24,
    paddingLeft: 20,
    paddingRight: 20,
    textAlign: 'center',
  TitleMessage: {
    fontSize: 16,
    lineHeight: 24,
    fontFamily: 'NunitoSans',
    fontWeight: '800',
    color: '#555',
  SubtitleMessage: {
    fontSize: 14,
    lineHeight: 20,
    color: '#666',
    fontFamily: 'NunitoSans',
  titlepage: {
    fontSize: 20,
    lineHeight: 24,
  TitleWrapper: {
    fontFamily: 'NunitoSans',
    fontWeight: '800',
    color: '#1c3f53',
    maxWidth: '100%',

Taskbox UI

If you want to modify the styling, the source LESS files are provided in the GitHub repo. And adjust accordingly for React Native styling.

Add assets

To match the intended design, you'll need to download both the font and icon directories and place them inside the assets folder.

We’ve used svn (Subversion) to easily download a folder of files from GitHub. If you don’t have subversion installed or want to just do it manually, you can grab the icons folder directly here and the font here.

svn export assets/icon
svn export assets/font

Next the assets need to be loaded into the app, for that we're going to update hooks/useCachedResources.js to the following:

async function loadResourcesAndDataAsync() {
  try {

    // Load fonts
    await Font.loadAsync({
      'space-mono': require('../assets/fonts/SpaceMono-Regular.ttf'),
      percolate: require('../assets/icon/percolate.ttf'),
      'NunitoSans-Bold': require('../assets/font/NunitoSans-Bold.ttf'),
      'NunitoSans-Italic': require('../assets/font/NunitoSans-Italic.ttf'),
      NunitoSans: require('../assets/font/NunitoSans-Regular.ttf'),
  } catch (e) {
    // We might want to provide this error information to an error reporting service
  } finally {

In order to use the icons from the percolate font safely and correctly in React Native we need to create a bridge that will map each individual icon to it's correspondent in the font file.

Create a new file /constants/Percolate.js with the following:

Click to expand and see the full file contents
 * PercolateIcons icon set component.
 * Usage: <PercolateIcons name="icon-name" size={20} color="#4F8EF7" />

import { createIconSet } from '@expo/vector-icons';

const iconSet = createIconSet(glyphMap, 'percolate');

export default iconSet;

export const Button = iconSet.Button;
export const TabBarItem = iconSet.TabBarItem;
export const TabBarItemIOS = iconSet.TabBarItemIOS;
export const ToolbarAndroid = iconSet.ToolbarAndroid;
export const getImageSource = iconSet.getImageSource;

In order to see Storybook in React Native we're going to update screens/LinksScreen.js to the following:

import * as React from 'react';
import StorybookUIRoot from '../storybook';

export default function LinksScreen() {
  return <StorybookUIRoot />;

And finally navigation/BottomTabNavigator.js to the following:

import * as React from 'react';
import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';
import TabBarIcon from '../components/TabBarIcon';
import HomeScreen from '../screens/HomeScreen';
import LinksScreen from '../screens/LinksScreen';

const BottomTab = createBottomTabNavigator();
const INITIAL_ROUTE_NAME = 'Home';

export default function BottomTabNavigator({ navigation, route }) {
  navigation.setOptions({ headerTitle: getHeaderTitle(route) });
  return (
    <BottomTab.Navigator initialRouteName={INITIAL_ROUTE_NAME}>
          title: 'Taskbox',
          tabBarIcon: ({ focused }) => <TabBarIcon focused={focused} name="md-code-working" />,
          title: 'Storybook',
          tabBarIcon: ({ focused }) => <TabBarIcon focused={focused} name="md-book" />,

function getHeaderTitle(route) {
  const routeName = route.state?.routes[route.state.index]?.name ?? INITIAL_ROUTE_NAME;

  switch (routeName) {
    case 'Home':
      return 'How to get started';
    case 'Links':
      return 'Your Storybook';

And finally, we'll need to make a small change to our Storybook configuration. As we're using Expo to build our app, we can safely remove some items from the configuration as they are not required. Turning the file contents into the following:

import { getStorybookUI, configure } from '@storybook/react-native';

import './rn-addons';

// import stories
configure(() => {
}, module);

const StorybookUIRoot = getStorybookUI({
  asyncStorage: null,

export default StorybookUIRoot;

We're adding the asyncStorage:null due to the fact that starting with React Native 0.59 Async Storage was deprecated. Should you need to use it in your own app, you'll have to add it manually by installing @react-native-async-storage/async-storage package and adjust the code above accordingly. You can read more about how to set up Storybook with Async Storage in here. As the tutorial will not use any of the features of Async Storage, we can safely add this element to Storybook configuration.

After adding styling and assets, the app will render a bit strangely. That’s OK. We aren’t working on the app right now. We’re starting off with building our first component!
