`enabled`

Type: boolean
Default: true

Whether to generate the sitemap.

`sortEntries`

Type: boolean
Default: true

Whether the sitemap entries should be sorted or be shown in the order they were added.

When enabled the entries will be sorted by the loc, they will be sorted by the path segment count and then alphabetically using String.localeCompare to ensure numbers are sorted correctly.

`sources`

Type: SitemapSource[]
Default: []

The sources to use for the sitemap. See Data Sources and Dynamic URL Endpoint for details.

`excludeAppSources`

Type: boolean|AppSourceId[]
Default: false

Whether to exclude app sources from the sitemap.

`appendSitemaps`

Type: (string | { sitemap: string, lastmod?: Date })[]
Default: false

Sitemaps to append to the sitemap index.

This will only do anything when using multiple sitemaps.

`autoLastmod`

Type: boolean
Default: false

Whether to automatically detect the lastmod date for each URL. If the lastmod date can't be inferred from a route page file it will use the current Date.

`sitemaps`

Type: SitemapConfig[] | boolean
Default: false

Whether to generate multiple sitemaps.

Each sitemap can have the following options:

SitemapConfig

`sources`

Type: SitemapSource[]
Default: []

Data sources for this specific sitemap.

`chunks`

Type: boolean | number
Default: undefined

Enable chunking for sitemap sources. This splits large collections of URLs from sources into multiple smaller sitemap files to stay within search engine limits.

Set to true to enable chunking with the default chunk size (from defaultSitemapsChunkSize or 1000)
Set to a positive number to use that as the chunk size (e.g., 5000 for 5000 URLs per chunk)
Set to false or leave undefined to disable chunking

Note: Chunking only applies to URLs from sources. Direct URLs in the urls property are not chunked.

export default defineNuxtConfig({
  sitemap: {
    sitemaps: {
      products: {
        sources: ['/api/products'],
        chunks: 5000 // Split into files with 5000 URLs each
      }
    }
  }
})

`chunkSize`

Type: number
Default: undefined

Explicitly set the chunk size for this sitemap. Takes precedence over the chunks property when both are specified.

export default defineNuxtConfig({
  sitemap: {
    sitemaps: {
      posts: {
        sources: ['/api/posts'],
        chunks: true,    // Enable chunking
        chunkSize: 2500  // Use 2500 URLs per chunk
      }
    }
  }
})

See the Chunking Sources guide for more details.

`urls`

Type: string[] | (() => string[] | Promise<string[]>)
Default: []

Static URLs to include in this sitemap.

`include`

Type: (string | RegExp)[]
Default: undefined

Filter URLs to include in this sitemap.

`exclude`

Type: (string | RegExp)[]
Default: undefined

Filter URLs to exclude from this sitemap.

`defaults`

Type: SitemapItemDefaults
Default: {}

Default values for all URLs in this sitemap.

`includeAppSources`

Type: boolean
Default: false

Whether to include automatic app sources in this sitemap.

See Multi Sitemaps for details.

`defaultSitemapsChunkSize`

Type: number | false
Default: 1000

The default chunk size when chunking is enabled for multi-sitemaps. This value is used when:

A sitemap has chunks: true (without specifying a number)
No chunkSize is explicitly set for the sitemap

Set to false to disable chunking by default for all sitemaps.

export default defineNuxtConfig({
  sitemap: {
    defaultSitemapsChunkSize: 5000,
    sitemaps: {
      // These will use 5000 as chunk size
      posts: {
        sources: ['/api/posts'],
        chunks: true
      },
      // This overrides the default
      products: {
        sources: ['/api/products'],
        chunks: 10000
      }
    }
  }
})

Default: []

Provide custom URLs to be included in the sitemap.xml.

`include`

Type: (string | RegExp)[]
Default: ['/**']

Filter routes that match the given rules. See the Filtering URLs guide for details.

    ]
  }
})
