ServiceWorkerRegistration.active
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
.
Value
A ServiceWorker
object's property, if it is currently in an
activating
or activated
state.
