Like you hinted at, in the alternatives, it's fairly straightforward to build out your own sitemap generation. So just for reference, an implementation idea that might work for you, using sitemap.. This assumes you have srcDir: './pages' set.

const fs = require('fs')
const path = require('path')
const fg = require('fast-glob')
const { SitemapStream, streamToPromise } = require('sitemap')

console.log('Start building sitemap..')

const linksStream = fg.stream(['./pages/*.md'])
  .map((filePath) => ({ url: filePath.replace('pages/', '').replace(/\.md$/, '.html') }))

const sitemapStream = new SitemapStream({ hostname: 'https://www.example.org' })

// Return a promise that resolves with your XML string
streamToPromise(linksStream.pipe(sitemapStream)).then((sitemap) => {
  fs.writeFileSync(
    path.resolve(__dirname, '../pages/public/sitemap.xml'),
    sitemap,
  )
})

Note that this uses Stream#readable.map, which is a brand new node feature, but you also implement it differently, if you don't want to rely on a experimental api.
It's also possible to use something like gray-matter, to include your meta data in your sitemaps, if needed.

If it can help, i have done a sitemap.xml and robots.txt generator using typescript: sitemap-ts.
This plugin was created and externalized from vite-ssg-sitemap ans is also used in vite-plugin-sitemap.

@jbaubree amazing, I'll check it out

any status on this?

@lmtr0
We need to wait next release of Vitepress with this pushed #709.
We will be able to configure like that :

// .vitepress/config.ts
import { version } from '../../../../packages/snap-design/package.json'
import { generateSitemap as sitemap } from 'sitemap-ts'

export default {
  vite: {
    buildEnd: () => {
      sitemap()
    },
  },
}

[lmtr0]

understood, for now a simple script solves my problem, thanks

On newer versions of VitePress this can be done (there is no need to traverse the dist directory):

import { createWriteStream } from 'node:fs'
import { resolve } from 'node:path'
import { SitemapStream } from 'sitemap'
import { defineConfig } from 'vitepress'

const links = []

export default {
  // ...

  transformHtml: (_, id, { pageData }) => {
    if (!/[\\/]404\.html$/.test(id))
      links.push({
        // you might need to change this if not using clean urls mode
        url: pageData.relativePath.replace(/((^|\/)index)?\.md$/, '$2'),
        lastmod: pageData.lastUpdated
      })
  },

  buildEnd: ({ outDir }) => {
    const sitemap = new SitemapStream({ hostname: 'https://vitepress.vuejs.org/' })
    const writeStream = createWriteStream(resolve(outDir, 'sitemap.xml'))
    sitemap.pipe(writeStream)
    links.forEach((link) => sitemap.write(link))
    sitemap.end()
  }
}

if not using clean urls mode, you can use this transformHtml

transformHtml: (_, id, { pageData }) => {
    if (!/[\\/]404\.html$/.test(id))
      links.push({
        url: pageData.relativePath.replace(/\.md$/, '.html'),
        lastmod: pageData.lastUpdated
      })
  },

Since release of 1.0.0-alpha.23 the script above does not create a file anymore even though the script runs through as far as I can judge.

Could it be that the buildEnd hook behaves differently than before? The bugfix "build: explicitly exit process after build to prevent hangup" sounds suspicious.

[brc-dd]

Ah right, it is exiting the process before stream can finish. Try this for now:

  buildEnd: async ({ outDir }) => {
    const sitemap = new SitemapStream({
      hostname: 'https://vitepress.vuejs.org/'
    })
    const writeStream = createWriteStream(resolve(outDir, 'sitemap.xml'))
    sitemap.pipe(writeStream)
    links.forEach((link) => sitemap.write(link))
    sitemap.end()
    await new Promise((r) => writeStream.on('finish', r))
  }
