Multiple subdomains for one worker

Developers Workers
1

Is it possible for a worker to have more than one subdomain (e.g. 1.example.com and 2.example.com) and it be able to tell the difference when handling the request? So domain 1 would say “hallo world”, and domain 2 would respond with “Goodbye world”

Short answer: Yes

How do you do it?

Start by adding multiple domains as per documentation

Then in the worker, check request.url for the hostname e.g.

export default {
  async fetch(request) {

    const url = new URL(request.url)
  
    if (url.hostname === "example.com")
      //  Return something

    if (url.hostname === "example.net")
      // Return something else

    // Other stuf here perhaps.
  }
}
