npx storybook init
npm run storybook  # Dev server
npm run build-storybook  # Production build

Story Example

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

const meta: Meta<typeof Button> = {
  component: Button,
  title: 'Components/Button',
  tags: ['autodocs'],
  argTypes: {
    variant: {
      control: { type: 'radio' },
      options: ['primary', 'secondary', 'ghost'],
    },
    size: {
      control: { type: 'radio' },
      options: ['sm', 'md', 'lg'],
    },
  },
};

export default meta;
type Story = StoryObj<typeof meta>;

export const Primary: Story = {
  args: { variant: 'primary', children: 'Click me' },
};

export const Secondary: Story = {
  args: { variant: 'secondary', children: 'Secondary' },
};

export const Disabled: Story = {
  args: { disabled: true, children: 'Disabled' },
};

// Interaction testing
export const Interactive: Story = {
  args: { variant: 'primary', children: 'Click' },
  play: async ({ canvasElement }) => {
    const button = canvasElement.querySelector('button');
    await userEvent.click(button);
  },
};
