### Types

#### `CreateSitemapItemsFn`

```ts
type CreateSitemapItemsFn = (params: {
  siteConfig: DocusaurusConfig;
  routes: RouteConfig[];
  defaultCreateSitemapItems: CreateSitemapItemsFn;
}) => Promise<SitemapItem[]>;
```

:::callout{intent="info"}
This plugin also respects some site config:

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

:::callout{intent="note"}
**About `lastmod`**

The `lastmod` option will only output a sitemap `<lastmod>` tag if plugins provide [route metadata](/guides/api-plugin-methods-lifecycle-apis#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

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

:::callout{intent="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',
  createSitemapItems: async (params) => {
    const {defaultCreateSitemapItems, ...rest} = params;
    const items = await defaultCreateSitemapItems(rest);
    return items.filter((item) => !item.url.includes('/page/'));
  },
};
```

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