Storybook for React Native

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

Storybook Screenshot

For more information visit: storybook.js.org

Getting Started

The storybook CLI tool can be used to add Storybook to your React Native app. Install the storybook tool if necessary and run it from your project directory with these commands:

cd my-rn-app
npx -p @storybook/cli sb init

The next thing you need to do is make Storybook UI visible in your app.

CRNA, React Native vanilla

The easiest way to use Storybook is to simply replace your App with the Storybook UI, which is possible by replacing App.js with a single line of code:

export default from "./storybook";

This will get you up and running quickly, but then you lose your app! There are multiple options here. for example, you can export conditionally:

import StorybookUI from "./storybook";

import App from "./app";

module.exports = __DEV__ ? StorybookUI : App;

React Native Navigation, other complex use cases

StorybookUI is simply a RN View component that can be embedded anywhere in your RN application, e.g. on a tab or within an admin screen.

Start Storybook server (optional)

If you want to control storybook from browser/VS Code/websockets you need to start the server. After initial setup start the storybook server with the storybook npm script.

npm run storybook

Now, you can open http://localhost:7007 to view your storybook menus in the browser.

Old standalone behaviour

Since storybook version v4.0 packager is removed from storybook. The suggested storybook usage is to include it inside your app. If you want to keep the old behaviour, you have to start the packager yourself with a different project root.

npm run storybook start -p 7007 | react-native start --projectRoot storybook

Start App

To see your Storybook stories on the device, you should start your mobile app for the <platform> of your choice (typically ios or android). (Note that due to an implementation detail, your stories will only show up in the left pane of your browser window after your device has connected to this storybook server.)

For CRNA apps:

npm run <platform>

For RN apps:

react-native run-<platform>

Once your app is started, changing the selected story in web browser will update the story displayed within your mobile app.

If you are using Android and you get the following error after running the app: 'websocket: connection error', 'Failed to connect to localhost/127.0.0.1:7007', you have to forward the port 7007 on your device/emulator to port 7007 on your local machine with the following command: adb reverse tcp:7007 tcp:7007

Start Command Parameters

The following parameters can be passed to the start command:

-h, --host <host>
    host to listen on
-p, --port <port>
    port to listen on
-s, --secured
    whether server is running on https
-c, --config-dir [dir-name]
    storybook config directory
-e, --environment [environment]
    DEVELOPMENT/PRODUCTION environment for webpack
-i, --manual-id
    allow multiple users to work with same storybook
--smoke-test
    Exit after successful start

getStorybookUI Options

{
    onDeviceUI: Boolean (true)
        -- display navigator and addons on the device
