SyncEvent

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 SyncEvent interface represents a sync action that is dispatched on the ServiceWorkerGlobalScope of a ServiceWorker.

This interface inherits from the ExtendableEvent interface.
