## Setup

```sh

npm i vitepress-plugin-auto-sidebar # npm
yarn add vitepress-plugin-auto-sidebar # yarn
```

## Basic usage

.vitepress/config.js
```javascript
import { getSidebar } from 'vitepress-plugin-auto-sidebar'

export default {
  themeConfig: {
    sidebar: getSidebar({ contentRoot: '/', contentDirs: ['team'], collapsible: true, collapsed: true })
  }
}
```

## Options

| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `contentRoot` | `string` | `'/'` | Root directory of your VitePress documentation (relative to project root) |
| `contentDirs` | `(string \| ContentDir)[]` | `['/']` | Array of directories to index within contentRoot. Can be simple strings or objects with `{ path: string, title?: string }` for custom titles |
| `collapsible` | `boolean` | `true` | Whether sidebar groups can be collapsed/expanded |
| `collapsed` | `boolean` | `true` | Whether sidebar groups are initially collapsed on page load |
| `useFrontmatter` | `boolean` | `false` | Whether to use frontmatter titles from markdown files instead of filename-based titles |

### Advanced Usage

#### Custom Directory Titles

```javascript
import { getSidebar } from 'vitepress-plugin-auto-sidebar'

export default {
  themeConfig: {
    sidebar: getSidebar({
      contentRoot: '/docs',
      contentDirs: [
        'getting-started',
        { path: 'api', title: 'API Reference' },
        { path: 'guides', title: '📚 User Guides' }
      ]
    })
  }
}
```

#### Using Frontmatter Titles

Add frontmatter to your markdown files:

```markdown
---
title: My Custom Page Title
---

# My Custom Page Title

Your content here...
```

Then enable frontmatter support:

```javascript
import { getSidebar } from 'vitepress-plugin-auto-sidebar'

export default {
  themeConfig: {
    sidebar: getSidebar({
      contentRoot: '/',
      contentDirs: ['docs'],
      useFrontmatter: true
    })
  }
}
```

### Tips & Best Practices

- **Ignore Files:** Prefix any `.md` file with an underscore (`_example.md`) to exclude it from the sidebar
- **Organize Structure:** Use clear, descriptive folder names - they become sidebar section titles
- **File Naming:** Use kebab-case for files (`my-page.md`) - they're automatically converted to "My Page"
- **Nested Directories:** The plugin recursively scans all subdirectories for a complete sidebar structure
- **Empty Directories:** Directories without any valid `.md` files are automatically excluded from the sidebar
