MDN’s new design is in Beta! A sneak peek:


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.getTags method of the SyncManager interface returns a list of developer-defined identifiers for SyncManager registrations.


SyncManager.getTags().then(function(tags[]) { ... })


A Promise that resolves to an array of DOMStrings containing developer-defined identifiers for SyncManager registrations.
