Feature flags

You can wrap your story with the withSplitTests utility to add split test variants to your Storybook stories, so you can toggle feature flags directly in the Storybook UI. See withSplitTests on GitHub.

1. Define your split test argTypes: Add your split test configurations to the splitTestsArgTypes object.

export const splitTestsArgTypes = {
  'local-ccy-format': {
    description: 'Use local currency formatting',
    control: { type: 'radio' },
    options: ['default', 'enabled'],
  },
}

2. Wrap your story with withSplitTests.

Import withSplitTests and Meta from '@storybook/react' in your stories.

export default {
  ...config,
  ...withSplitTests(config, ['local-ccy-format']),
}

Example

Resulting stories will have added controls to define the variants of the split tests.
