You can use the `generateSitemaps` function to generate multiple sitemaps for your application.
## Returns
The `generateSitemaps` returns an array of objects with an `id` property.
## URLs
Your generated sitemaps will be available at `/.../sitemap/[id].xml`. For example, `/product/sitemap/1.xml`.
## Example
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.
```ts filename="app/product/sitemap.ts" switcher
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({
id,
}: {
id: number
}): Promise<MetadataRoute.Sitemap> {
// 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,
}))
}
```
```js filename="app/product/sitemap.js" switcher
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({ 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/${id}`,
lastModified: product.date,
}))
}
```
