Storybook Addon Actions can be used to display data received by event handlers in Storybook.

This addon works with Storybook for:

• React
• React Native
• Vue.

Install:

npm i -D @storybook/addon-actions

Then, add following content to .storybook/addons.js

import '@storybook/addon-actions/register';

Import the action function and use it to create actions handlers. When creating action handlers, provide a name to make it easier to identify.

Note: Make sure NOT to use reserved words as function names. issues#29

import { storiesOf } from '@storybook/react';
import { action } from '@storybook/addon-actions';

import Button from './button';

storiesOf('Button', module)
  .add('default view', () => (
    <Button onClick={ action('button-click') }>
      Hello World!
    </Button>
  ))

If you wish to process action data before sending them over to the logger, you can do it with action decorators.

decorateAction takes an array of decorator functions. Each decorator function is passed an array of arguments, and should return a new arguments array to use. decorateAction returns a function that can be used like action but will log the modified arguments instead of the original arguments.

import { decorateAction } from '@storybook/addon-actions';

import Button from './button';

const firstArgAction = decorateAction([
  args => args.slice(0, 1)
]);

storiesOf('Button', module)
  .add('default view', () => (
    <Button onClick={ firstArgAction('button-click') }>
      Hello World!
    </Button>
  ))
