SyncManager

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 SyncManager interface of the the ServiceWorker API provides an interface for registering and listing sync registrations.

Properties

None.

Methods

SyncManager.register: Create a new sync registration and return a Promise.
