ServiceWorkerRegistration.periodicSync

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The periodicSync read-only property of the ServiceWorkerRegistration interface returns a reference to the PeriodicSyncManager interface, which manages periodic background synchronization processes.

Syntax

myPeriodicSync = ServiceWorker.periodicSync 

Value

A PeriodicSyncManager object.

Examples
