Using Storybook and LaunchDarkly


If you use LaunchDarkly to feature flag your app and you use storybook, then here's a way to run your feature flagged components in storybook.

The example below assumes a Button component that uses the LaunchDarkly react sdk to access flags via the useFlags hook.

import React from 'react'
import { withLDProvider } from 'launchdarkly-react-client-sdk'
import Button from './button'

export default { title: 'Buttons' }

// 1. Write your standard story component
const EmojiButton = () => (
  <Button backgroundColor="blue">
    <span role="img" aria-label="so cool">
      😀 😎 👍 💯

// 2. Then wrap it with withLDProvider
const LDEmojiButton = withLDProvider({ clientSideID: 'your-client-side-id' })(EmojiButton)

// 3. Finaly export the wrapped component
export const withLDEmoji = () => <LDEmojiButton />

You will be able to target users and turn features on/off in storybook like you can in your app! The possibilities are endless.

See the complete sample app which you can run on github.
