@storybook/addons

What is @storybook/addons?

The @storybook/addons package is a core module for Storybook that provides the infrastructure to build and use addons, which are essentially plugins that can be used to extend Storybook's UI and behavior. Addons can be used to add new features, integrate with other tools, customize the panel within Storybook, and enhance the development workflow.

What are @storybook/addons's main functionalities?

Addon Registration

This feature allows developers to register new addons with Storybook. The code sample demonstrates how to import the addons API and use it to register a custom addon.

import { addons } from '@storybook/addons';
import MyAddon from './my-addon';

addons.register('my-addon', MyAddon);

Addon Panel Creation

This feature allows developers to create new panels in the Storybook UI. The code sample shows how to add a new panel using the addons API.

import { addons, types } from '@storybook/addons';
import MyPanel from './my-panel';

addons.add('my-panel', {
  type: types.PANEL,
  title: 'My Panel',
  render: ({ active, key }) => (
    <MyPanel active={active} key={key} />
  )
});

Addon Tool Registration

This feature enables the addition of tools to the Storybook toolbar. The code sample illustrates how to register a new tool that will be displayed when the view mode is set to 'story'.

import { addons, types } from '@storybook/addons';
import MyTool from './my-tool';

addons.add('my-tool', {
  type: types.TOOL,
  title: 'My Tool',
  match: ({ viewMode }) => viewMode === 'story',
  render: MyTool
});
