Find window previously opened by window.open

Question

We\'ve got the following situation, running from a single domain:

Page A uses window.open() to open a named window (a popup player). window.open()

Answer 1

If all the windows share a common Url origin you can register a ServiceWorker and then access all windows from the ServiceWorker: https://developer.mozilla.org/en-US/docs/Web/API/Clients

AFAIK You won't be able to pass a reference to other windows from WorkerService to your window but you can establish communications with the ServiceWorker via
