This is the public documentation site for Superset, built using
[Docusaurus 3](https://docusaurus.io/). See
[CONTRIBUTING.md](../CONTRIBUTING.md#documentation) for documentation on
contributing to documentation.

## Version Management

The Superset documentation site uses Docusaurus versioning with three independent versioned sections:

- **Main Documentation** (`/docs/`) - Core Superset documentation
- **Developer Portal** (`/developer_portal/`) - Developer guides and tutorials  
- **Component Playground** (`/components/`) - Interactive component examples (currently disabled)

Each section maintains its own version history and can be versioned independently.

### Creating a New Version

To create a new version for any section, use the Docusaurus version command with the appropriate plugin ID or use our automated scripts:

#### Using Automated Scripts (Required)

**⚠️ Important:** Always use these custom commands instead of the native Docusaurus commands. These scripts ensure that both the Docusaurus versioning system AND the `versions-config.json` file are updated correctly.

```bash
# Main Documentation
yarn version:add:docs 1.2.0

# Developer Portal
yarn version:add:developer_portal 1.2.0

# Component Playground (when enabled)
yarn version:add:components 1.2.0
```

**Do NOT use** the native Docusaurus commands directly (`yarn docusaurus docs:version`), as they will:
- ❌ Create version files but NOT update `versions-config.json`
- ❌ Cause versions to not appear in dropdown menus
- ❌ Require manual fixes to synchronize the configuration

### Managing Versions

#### With Automated Scripts
The automated scripts handle all configuration updates automatically. No manual editing required!

#### Manual Configuration
If creating versions manually, you'll need to:

1. **Update `versions-config.json`** (or `docusaurus.config.ts` if not using dynamic config):
   - Add version to `onlyIncludeVersions` array
   - Add version metadata to `versions` object
   - Update `lastVersion` if needed

2. **Files Created by Versioning**:
   When a new version is created, Docusaurus generates:
   - **Versioned docs folder**: `[section]_versioned_docs/version-X.X.X/`
   - **Versioned sidebars**: `[section]_versioned_sidebars/version-X.X.X-sidebars.json`
   - **Versions list**: `[section]_versions.json`

   Note: For main docs, the prefix is omitted (e.g., `versioned_docs/` instead of `docs_versioned_docs/`)

3. **Important**: After adding a version, restart the development server to see changes:
   ```bash
   yarn stop
   yarn start
   ```

### Removing a Version

#### Using Automated Scripts (Recommended)
```bash
# Main Documentation
yarn version:remove:docs 1.0.0

# Developer Portal
yarn version:remove:developer_portal 1.0.0

# Component Playground
yarn version:remove:components 1.0.0
```

#### Manual Removal
To manually remove a version:

1. **Delete the version folder** from the appropriate location:
   - Main docs: `versioned_docs/version-X.X.X/` (no prefix for main)
   - Developer Portal: `developer_portal_versioned_docs/version-X.X.X/`
   - Components: `components_versioned_docs/version-X.X.X/`

2. **Delete the version metadata file**:
   - Main docs: `versioned_sidebars/version-X.X.X-sidebars.json` (no prefix)
   - Developer Portal: `developer_portal_versioned_sidebars/version-X.X.X-sidebars.json`
   - Components: `components_versioned_sidebars/version-X.X.X-sidebars.json`

3. **Update the versions list file**:
   - Main docs: `versions.json`
   - Developer Portal: `developer_portal_versions.json`
   - Components: `components_versions.json`

4. **Update configuration**:
   - If using dynamic config: Update `versions-config.json`
   - If using static config: Update `docusaurus.config.ts`

5. **Restart the server** to see changes

### Version Configuration Examples

#### Main Documentation (default plugin)
```typescript
docs: {
  includeCurrentVersion: true,
  lastVersion: 'current',  // Makes /docs/ show Next version
  onlyIncludeVersions: ['current', '1.1.0', '1.0.0'],
  versions: {
    current: {
      label: 'Next',
      path: '',  // Empty path for default routing
      banner: 'unreleased',
    },
    '1.1.0': {
      label: '1.1.0',
      path: '1.1.0',
      banner: 'none',
    },
  },
}
```

#### Developer Portal & Components (custom plugins)
```typescript
{
  id: 'developer_portal',
  path: 'developer_portal',
  routeBasePath: 'developer_portal',
  includeCurrentVersion: true,
  lastVersion: '1.1.0',  // Default version
  onlyIncludeVersions: ['current', '1.1.0', '1.0.0'],
  versions: {
    current: {
      label: 'Next',
      path: 'next',
      banner: 'unreleased',
    },
    '1.1.0': {
      label: '1.1.0',
      path: '1.1.0',
      banner: 'none',
    },
  },
}
```

### Best Practices

1. **Version naming**: Use semantic versioning (e.g., 1.0.0, 1.1.0, 2.0.0)
2. **Version banners**: Use `'unreleased'` for development versions, `'none'` for stable releases
3. **Limit displayed versions**: Use `onlyIncludeVersions` to show only relevant versions
4. **Test locally**: Always test version changes locally before deploying
5. **Independent versioning**: Each section can have different version numbers and release cycles

### Troubleshooting

#### Version Not Showing After Creation

If you accidentally used `yarn docusaurus docs:version` instead of `yarn version:add`:
1. **Problem**: The version files were created but `versions-config.json` wasn't updated
2. **Solution**: Either:
   - Revert the changes: `git restore versions.json && rm -rf versioned_docs/ versioned_sidebars/`
   - Then use the correct command: `yarn version:add:docs <version>`

For other issues:
- **Restart the server**: Changes to version configuration require a server restart
- **Check config file**: Ensure `versions-config.json` includes the new version
- **Verify files exist**: Check that versioned docs folder was created

#### Broken Links in Versioned Documentation
When creating a new version, links in the documentation are preserved as-is. Common issues:
- **Cross-section links**: Links between sections (e.g., from developer_portal to docs) need to be version-aware
- **Absolute vs relative paths**: Use relative paths within the same section
- **Version-specific URLs**: Update hardcoded URLs to use version variables

To fix broken links:
1. Use `type: 'doc'` with `docId` for version-aware navigation in navbar
2. Use relative paths within the same documentation section
3. Test all versions after creation to identify broken links
