Service Worker + Push API

Motivation

The current Push API Draft specifies a system that has no notion of push channel persistence. Further, it does not include push message payloads, a feature that many developers want.

This gist outlines an API which:

  • integrates with the Service Worker to enable delivery of push messages to applications which do not have visible tabs
  • enables a JSON-formatted body of content
  • guards access to registration for pushes on potential user consent
