How to dynamically generate sitemap.xml/robots.txt for project using host rewrites?

[TrustyTechSG]

Hi we are using rewrites to dynamically generate site base on visiting hostname, which works great. but for the sitemap.xml/robots.txt, as both of them need to place direct under root folder of app directory, then how can we generate them base on the hostname?

  async rewrites() {
    return {
      beforeFiles: [
        {
          has: [
            {
              type: "host",
              value: "(?<host>.*)",
            },
          ],
          source: "/:path*",
          destination: "/hosts/:host/:path*",
        },

Hey @TrustyTechSG, If you are looking for dynamically create sitemap and robots then you have to create sitemap.ts and robots.ts in the app dir.

Details and syntax can be found here - Generate a Sitemap & Generate a Robots file

Hi there. thank you for the reply, yes I saw this, but these function are not passing in any params is it? We need the params to get the hostname.

We have rewrite rules to rewrite all visit under
/hosts/[hostname]
So we need to put the sitemap.ts and robots.ts under /hosts/[hostname] folder and get the hostname params as argument, it is currently not possible is it?
