Periodic Background Sync

Periodic Background Sync is an extension of Background Sync that allows websites to register tasks to be run in a service worker at periodic intervals with network connectivity.

The API will allow offline-first web apps to periodically update state, and will allow periodic content producers like news sites to push content to users’ devices periodically. At present, sites can achieve this using Push messages, but need to set up a server for that.
