An automatic story loader for react-native-storybooks
React Native Storybook Loader
A CLI for dynamically importing stories into Storybook for React Native.
Purpose
While using storybook for React Native, I repeatedly found myself manually creating a file with imports for all my stories.
react native storybook-loader
solves this by searching directories, matching files to patterns and generating a story loader that Storybook can use to load all of your stories.

Installation
yarn add react-native-storybook-loader -D
Quick Start
-
Create a React Native project using create-react-native-app
yarn create react-native-app
-
Add Storybook for React Native to the project and follow instructions to finalize setup.
cd <project name> npx -p @storybook/cli sb init --type react_native
-
Install react-native-storybook-loader
yarn add react-native-storybook-loader -D
-
Add the
rnstl
cli to the scripts tag of thepackage.json
{ "scripts": { "prestorybook": "rnstl" } }
-
Update
index.js
file in the./storybook
directory to point tostoryLoader.js
import { AppRegistry } from 'react-native'; import { getStorybookUI, configure } from '@storybook/react-native'; import { loadStories } from './storyLoader'; import './rn-addons'; // import stories configure(() => { loadStories(); }, module); // Refer to https://github.com/storybookjs/storybook/tree/master/app/react-native#start-command-parameters // To find allowed options for getStorybookUI const StorybookUIRoot = getStorybookUI({}); // If you are using React Native vanilla and after installation you don't see your app name here, write it manually. // If you use Expo you can safely remove this line. AppRegistry.registerComponent('%APP_NAME%', () => StorybookUIRoot); export default StorybookUIRoot;
Note: Step 4 ensures
storyLoader.js
will be created -
Start Storybook
yarn storybook
-
Run react native app in targeted platform
yarn android
Or
yarn ios
Note: If you have problems connecting from your device to Storybook using Android issue the following command:
adb reverse tcp:7007 tcp:7007
.
Configuration
Story loading is controlled by the react-native-storybook-loader
section of the project's package.json
.
Options
Setting | CLI Option | Type | Description | Default |
---|---|---|---|---|
searchDir | --searchDir |
string or string[] |
The directory or directories, relative to the project root, to search for files in. | Project root |
outputFile | --outputFile |
string |
The output file that will be written. It is relative to the project directory. | ./storybook/storyLoader.js |
pattern | --pattern |
string |
The pattern of files to look at. It can be a specific file, or any valid glob. Note: if using the CLI, globs with **/*... must be escaped with quotes |
./storybook/stories/index.js (The default React Native storybook file) |
--silent |
Silences output. This option is not supported in the package.json file. |
Note: When using the CLI, any of option passed will override the values in the
package.json
Examples:
Both examples below will search src
and packages
directories recursively for files that end with .stories.js
and write the output to ./storybook/storyLoader.js
package.json
{
"name": "awesome-project",
"scripts": {
"prestorybook": "rnstl"
},
"config": {
"react-native-storybook-loader": {
"searchDir": ["./src", "./packages"],
"pattern": "**/*.stories.js",
"outputFile": "./storybook/storyLoader.js"
}
}
}
Story Loader API
A story loader is the file generated by rnstl
used to load story files from your project in to Storybook.
storyLoader.loadStories()
Loads the located stories
Returns: void
storyLoader.stories
An array of the stories that are loaded.
Returns: string[]
storyLoader.modules
An array of the modules to load.
Returns: NodeRequire[]
Story Loader Formatting
To ensure the formatting of your story loader is on par with the rest of your code base, rnstl
uses Prettier to format the generated story loaders. It will travese up the tree looking for a Prettier configuration file. If none is found, the defaul Prettier settings will be used.
