Instruction

here's a script for setting up at a subdirectory when you want to host in a subdomain. add this to our docs.

function handleRequest(request) {
  const url = new URL(request.url);

  if (url.pathname.toLocaleLowerCase().startsWith('/docs') && !url.pathname.toLocaleLowerCase().startsWith('/docs.json')) {
    url.hostname = 'mintlify.mintlify.dev';
    return fetch(url.toString(), request);
  } else {
    url.hostname = 'landing.mintlify.com';
    return fetch(url.toString(), request);
  }
}

addEventListener('fetch', event => {
  event.respondWith(handleRequest(event.request));
});
