| Name | Type | Default | Description |
| --- | --- | --- | --- |
| `lastmod` | `'date' \| 'datetime' \| null` | `null` | `date` is YYYY-MM-DD. `datetime` is a ISO 8601 datetime. `null` is disabled. See [sitemap docs](https://www.sitemaps.org/protocol.html#xmlTagDefinitions). |
| `changefreq` | `string \| null` | `'weekly'` | See [sitemap docs](https://www.sitemaps.org/protocol.html#xmlTagDefinitions) |
| `priority` | `number \| null` | `0.5` | See [sitemap docs](https://www.sitemaps.org/protocol.html#xmlTagDefinitions) |
| `ignorePatterns` | `string[]` | `[]` | A list of glob patterns; matching route paths will be filtered from the sitemap. Note that you may need to include the base URL in here. |
| `filename` | `string` | `sitemap.xml` | The path to the created sitemap file, relative to the output directory. Useful if you have two plugin instances outputting two files. |

```mdx-code-block
</APITable>
```

:::info

This plugin also respects some site config:

- [`noIndex`](../docusaurus.config.js.mdx#noIndex): results in no sitemap generated
- [`trailingSlash`](../docusaurus.config.js.mdx#trailingSlash): determines if the URLs in the sitemap have trailing slashes

:::

:::note About `lastmod`

The `lastmod` option will only output a sitemap `<lastmod>` tag if plugins provide [route metadata](../plugin-methods/lifecycle-apis.mdx#addRoute) attributes `sourceFilePath` and/or `lastUpdatedAt`.

All the official content plugins provide the metadata for routes backed by a content file (Markdown, MDX or React page components), but it is possible third-party plugin authors do not provide this information, and the plugin will not be able to output a `<lastmod>` tag for their routes.

:::

### Example configuration {#ex-config}

You can configure this plugin through preset options or plugin options.

:::tip

Most Docusaurus users configure this plugin through the preset options.

:::

```js config-tabs
// Preset Options: sitemap
// Plugin Options: @docusaurus/plugin-sitemap

const config = {
  lastmod: 'date',
  changefreq: 'weekly',
  priority: 0.5,
  ignorePatterns: ['/tags/**'],
  filename: 'sitemap.xml',
};
```

You can find your sitemap at `/sitemap.xml`.
