Skill: Storybook Component Documentation

Purpose

To develop, test, and document UI components in isolation from the main application.

When to Use

• Building a Design System.
• Visual testing.
• Collaborating with designers.

Procedure

1. Setup

npx storybook@latest init

2. Writing Stories

A story captures a specific state of a component. Button.stories.tsx:

import type { Meta, StoryObj } from '@storybook/react';
import { Button } from './Button';

const meta: Meta<typeof Button> = {
  component: Button,
  title: 'Components/Button',
};
export default meta;

type Story = StoryObj<typeof Button>;

export const Primary: Story = {
  args: {
    primary: true,
    label: 'Button',
  },
};

export const Secondary: Story = {
  args: {
    label: 'Button',
  },
};

3. Addons

• Controls: Edit props dynamically in the UI.
• Actions: Log events (clicks).
• Docs: Auto-generate documentation from comments (JSDoc).

4. Testing

Use Interaction Testing (play function) to simulate user behavior within Storybook.

Constraints

• Maintenance: Stories must be updated when component props change.
• Context: Components relying on global providers (Redux, Router) need decorators in .storybook/preview.js to work.

Expected Output

A living style guide where every component state is cataloged and interactive.
