|
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
|
|
|
|
In production, your generated sitemaps will be available at `/.../sitemap/[id].xml`. For example, `/product/sitemap/1.xml`.
|
|
|
|
In development, you can view the generated sitemap on `/.../sitemap.xml/[id]`. For example, `/product/sitemap.xml/1`. This difference is temporary and will follow the production format.
|
|
|
|
## 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,
|
|
}))
|
|
}
