Put a worker live // where should the A record point?


I wrote a super simple worker from the editor:

addEventListener('fetch', event => {
  const meta = {
    headers: {
      "Content-Type": "text/html",
    status: 200,
  const body = `<!DOCTYPE html>
      <title>My App</title>
      <h1>My App</h1>
      <p>url: ${event.request.url}</p>
    new Response(body, meta)

And it is working in the Cloudflare frame. But not from the actual website.

I enabled the website on those routes:

What did I miss ?

(I enabled the workers and payed for it. And I did hit the deploy button.)

(And the error I have when I try to curl is “Could not resolve host”)

Oh, I think I know what went wrong. I have no A record

An A, AAAA or CNAME record was not found pointing to the root domain. The my-ndd.tld domain will not resolve.

Where should the A record point if the only thing I want is a worker ?

If the worker is acting purely as an endpoint and not a proxy, the A record can point anywhere. Common choices are to point the A/AAAA at your registrar’s default parking site, or CNAME it to your GitHub Pages domain if you have one.

This requirement is admittedly a little silly, since presumably you’re not going to forward any subrequest to the origin. It is a consequence of the history of our infrastructure’s primary use as a proxy, and we hope to remove the requirement at some point.


Oh, right!

I added an A record to and now everything is working. Thank you very much.

It could be mentioned somewhere :slight_smile:
