An example using Service Worker?

When I saw this I assumed I could slot a service worker in the same place a web worker was being used in the example, but service workers don’t have self.postMessage, so it doesn’t work. I’ve got it working now by hooking up the proxy through a MessagePort in a message event - is that the best way to do it?

Either way, it would be great to have an example showing the best practise for this.

You are right, a ServiceWorker doesn’t have self.postMessage at there might be potentially multiple open windows. So yeah, sending a MessagePort is one good solution. Another option would be to get the actual window object using self.clients.get() or self.clients.matchAll().

It’s probably a good idea for me to write an example for this.

Hope this helps.

I think I like your solution better. I’ll adjust my PR 😃
