# React Native Storybook Stories

Write stories for React Native components using `@storybook/react-native` v10 and Component Story Format (CSF).

## Quick Start

Minimal story file:

```tsx
import type { Meta, StoryObj } from '@storybook/react-native';
import { MyComponent } from './MyComponent';

const meta = {
  component: MyComponent,
} satisfies Meta<typeof MyComponent>;

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

export const Basic: Story = {
  args: {
    label: 'Hello',
  },
};
```

## File Conventions

- Name: `ComponentName.stories.tsx` colocated with the component
- Import `Meta` and `StoryObj` from `@storybook/react-native`
- Default export: `meta` object with `satisfies Meta<typeof Component>`
- Named exports: UpperCamelCase story names, typed as `StoryObj<typeof meta>`
- Use `args` for props, `argTypes` for control config, `parameters` for addon config
- Use `render` for custom render functions, `decorators` for wrappers

## Story Patterns

### Multiple stories with shared args

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

export const Secondary: Story = {
  args: { ...Primary.args, variant: 'secondary' },
};
```

### Custom render function

```tsx
export const WithScrollView: Story = {
  render: (args) => (
    <ScrollView>
      <MyComponent {...args} />
    </ScrollView>
  ),
};
```

### Render with hooks (must be a named function)

```tsx
export const Interactive: Story = {
  render: function InteractiveRender() {
    const [count, setCount] = useReducer((s) => s + 1, 0);
    return <Counter count={count} onPress={setCount} />;
  },
};
```

### Actions (mock callbacks)

```tsx
import { fn } from 'storybook/test';

const meta = {
  component: Button,
  args: { onPress: fn() },
} satisfies Meta<typeof Button>;
```

Or via argTypes:

```tsx
argTypes: { onPress: { action: 'pressed' } },
```

### Custom story name

```tsx
export const MyStory: Story = {
  storyName: 'Custom Display Name',
  args: { label: 'Hello' },
};
```

### Custom title / nesting

```tsx
const meta = {
  title: 'NestingExample/Message/Bubble',
  component: MyComponent,
} satisfies Meta<typeof MyComponent>;
```

## Controls & ArgTypes

For the full control type reference, see [references/controls.md](references/controls.md).

Common patterns:

```tsx
const meta = {
  component: MyComponent,
  argTypes: {
    // Select dropdown
    size: {
      options: ['small', 'medium', 'large'],
      control: { type: 'select' },
    },
    // Range slider
    opacity: {
      control: { type: 'range', min: 0, max: 1, step: 0.1 },
    },
    // Color picker
    color: { control: { type: 'color' } },
    // Conditional control (shows only when `advanced` arg is true)
    padding: { control: 'number', if: { arg: 'advanced' } },
  },
} satisfies Meta<typeof MyComponent>;
```

Auto-detection: TypeScript prop types are automatically mapped to controls (`string` -> text, `boolean` -> boolean, union types -> select, `number` -> number).

## Parameters

### Addon parameters

```tsx
parameters: {
  // Markdown docs in the Notes addon tab
  notes: `# MyComponent\nUsage: \`<MyComponent label="hi" />\``,
  // Background options for Backgrounds addon
  backgrounds: {
    default: 'dark',
    values: [
      { name: 'light', value: 'white' },
      { name: 'dark', value: '#333' },
    ],
  },
},
```

### RN-specific UI parameters

| Parameter               | Type                                         | Description                                                                                                                                                                                                                                                                                                                                                                      |
| ----------------------- | -------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `noSafeArea`            | `boolean`                                    | Remove top safe area padding. **When using this, the component itself must handle safe areas** since Storybook will no longer provide safe area padding. Prefer `useSafeAreaInsets()` over `SafeAreaView` — apply insets as `paddingTop`/`paddingBottom` on the container, and for scrollable content use `contentContainerStyle` padding instead of wrapping in `SafeAreaView`. |
| `storybookUIVisibility` | `'visible'` \| `'hidden'`                    | Initial UI visibility                                                                                                                                                                                                                                                                                                                                                            |
| `hideFullScreenButton`  | `boolean`                                    | Hide fullscreen toggle                                                                                                                                                                                                                                                                                                                                                           |
| `layout`                | `'padded'` \| `'centered'` \| `'fullscreen'` | Story container layout                                                                                                                                                                                                                                                                                                                                                           |

Parameters can be set at story, meta (component), or global (preview.tsx) level.

## Decorators

Wrap stories in providers, layouts, or context:

```tsx
const meta = {
  component: MyComponent,
  decorators: [
    (Story) => (
      <View style={{ alignItems: 'center', justifyContent: 'center', flex: 1 }}>
        <Story />
      </View>
    ),
  ],
} satisfies Meta<typeof MyComponent>;
```

Global decorators go in `.rnstorybook/preview.tsx`:

```tsx
import { withBackgrounds } from '@storybook/addon-ondevice-backgrounds';
import type { Preview } from '@storybook/react-native';

const preview: Preview = {
  decorators: [withBackgrounds],
  parameters: {
    actions: { argTypesRegex: '^on[A-Z].*' },
    controls: {
      matchers: {
        color: /(background|color)$/i,
        date: /Date$/,
      },
    },
    backgrounds: {
      default: 'plain',
      values: [
        { name: 'plain', value: 'white' },
        { name: 'dark', value: '#333' },
      ],
    },
  },
};

export default preview;
```

## Configuration

### .rnstorybook/main.ts

```ts
import type { StorybookConfig } from '@storybook/react-native';

const main: StorybookConfig = {
  stories: ['../components/**/*.stories.?(ts|tsx|js|jsx)'],
  deviceAddons: [
    '@storybook/addon-ondevice-controls',
    '@storybook/addon-ondevice-backgrounds',
    '@storybook/addon-ondevice-actions',
    '@storybook/addon-ondevice-notes',
  ],
  framework: '@storybook/react-native',
};

export default main;
```

Story globs also support the object form for multi-directory setups:

```ts
stories: [
  '../components/**/*.stories.?(ts|tsx|js|jsx)',
  { directory: '../other_components', files: '**/*.stories.?(ts|tsx|js|jsx)' },
],
```

## Portable Stories (Testing)

Reuse stories in Jest tests:

```tsx
import { render, screen } from '@testing-library/react-native';
import { composeStories } from '@storybook/react';
import * as stories from './Button.stories';

const { Primary, Secondary } = composeStories(stories);

test('renders primary button', () => {
  render(<Primary />);
  expect(screen.getByText('Click me')).toBeTruthy();
});

// Override args in tests
test('renders with custom props', () => {
  render(<Primary title="Custom" />);
  expect(screen.getByText('Custom')).toBeTruthy();
});
```

For single stories use `composeStory`:

```tsx
import { composeStory } from '@storybook/react';
import meta, { Primary } from './Button.stories';

const PrimaryStory = composeStory(Primary, meta);
```

Setup global annotations for tests in a Jest setup file:

```ts
// setup-portable-stories.ts
import { setProjectAnnotations } from '@storybook/react';
import * as previewAnnotations from '../.rnstorybook/preview';
setProjectAnnotations(previewAnnotations);
```
