The active
property of the ServiceWorkerRegistration
interface returns a service worker whose ServiceWorker.state
is activating
or activated
. This property is initially set to null
.
An active worker controls a Client
if the client's URL falls within the scope of the registration (the scope
option set when ServiceWorkerContainer.register
is first called.)
Note: This feature is available in Web Workers.
Note: Once an active worker is activating
, neither a runtime script error nor a force termination of the active worker prevents the active worker from getting activated
.
