sitemap.xml

Section titled “sitemap.xml”

sitemap.(xml|js|ts) is a special file that matches the Sitemaps XML format to help search engine crawlers index your site more efficiently.

Sitemap files (.xml)

Section titled “Sitemap files (.xml)”

For smaller applications, you can create a sitemap.xml file and place it in the root of your app directory.

Generating a sitemap using code (.js, .ts)

Section titled “Generating a sitemap using code (.js, .ts)”

You can use the sitemap.(js|ts) file convention to programmatically generate a sitemap by exporting a default function that returns an array of URLs. If using TypeScript, a Sitemap type is available.

Good to know: sitemap.js is a special Route Handler that is cached by default unless it uses a Dynamic API or dynamic config option.

import type { MetadataRoute } from 'next'


export default function sitemap(): MetadataRoute.Sitemap {
  return [
    {
      url: 'https://acme.com',
      lastModified: new Date(),
      changeFrequency: 'yearly',
      priority: 1,
    },
    {
      url: 'https://acme.com/about',
      lastModified: new Date(),
      changeFrequency: 'monthly',
      priority: 0.8,
    },
    {
      url: 'https://acme.com/blog',
      lastModified: new Date(),
      changeFrequency: 'weekly',
      priority: 0.5,
    },
  ]
}
export default function sitemap() {
  return [
    {
      url: 'https://acme.com',
      lastModified: new Date(),
      changeFrequency: 'yearly',
      priority: 1,
    },
    {
      url: 'https://acme.com/about',
      lastModified: new Date(),
      changeFrequency: 'monthly',
      priority: 0.8,
    },
    {
      url: 'https://acme.com/blog',
      lastModified: new Date(),
      changeFrequency: 'weekly',
      priority: 0.5,
    },
  ]
}

Output:

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">

Generating multiple sitemaps

Section titled “Generating multiple sitemaps”

While a single sitemap will work for most applications. For large web applications, you may need to split a sitemap into multiple files.

There are two ways you can create multiple sitemaps:

  • By nesting sitemap.(xml|js|ts) inside multiple route segments e.g. app/sitemap.xml and app/products/sitemap.xml.
  • By using the generateSitemaps function.

For example, to split a sitemap using generateSitemaps, return an array of objects with the sitemap id. Then, use the id to generate the unique sitemaps.

import type { MetadataRoute } from 'next'
import { BASE_URL } from '@/app/lib/constants'


export async function generateSitemaps() {
  // Fetch the total number of products and calculate the number of sitemaps needed
  return [{ id: 0 }, { id: 1 }, { id: 2 }, { id: 3 }]
}


export default async function sitemap(props: {
  id: Promise<string>
}): Promise<MetadataRoute.Sitemap> {
  const id = await props.id
  // Google's limit is 50,000 URLs per sitemap
  const start = id * 50000
  const end = start + 50000
  const products = await getProducts(
    `SELECT id, date FROM products WHERE id BETWEEN ${start} AND ${end}`
  )
  return products.map((product) => ({
    url: `${BASE_URL}/product/${product.id}`,
    lastModified: product.date,
  }))
}
import { BASE_URL } from '@/app/lib/constants'


export async function generateSitemaps() {
  // Fetch the total number of products and calculate the number of sitemaps needed
  return [{ id: 0 }, { id: 1 }, { id: 2 }, { id: 3 }]
}


export default async function sitemap(props) {
  const id = await props.id
  // Google's limit is 50,000 URLs per sitemap
  const start = id * 50000
  const end = start + 50000
  const products = await getProducts(
    `SELECT id, date FROM products WHERE id BETWEEN ${start} AND ${end}`
  )
  return products.map((product) => ({
    url: `${BASE_URL}/product/${product.id}`,
    lastModified: product.date,
  }))
}

Your generated sitemaps will be available at /.../sitemap/[id]. For example, /product/sitemap/1.xml.

See the generateSitemaps API reference for more information.

Returns

Section titled “Returns”

The default function exported from sitemap.(xml|ts|js) should return an array of objects with the following properties:

type Sitemap = Array<{
  url: string
  lastModified?: string | Date
  changeFrequency?:
    | 'always'
    | 'hourly'
    | 'daily'
    | 'weekly'
    | 'monthly'
    | 'yearly'
    | 'never'
  priority?: number
  alternates?: {
    languages?: Languages<string>
  }
}>
