Overview

Push Notifications is a feature that enables web applications to efficiently notify users even when off-site. It's intended as a standards compliant feature utilizing Push API, Notifications API, WebPush Service.

Currently, email is the only reliable way for a web application to contact or notify users on desktop computers. Push Notifications introduces functionality for web applications to contact users when off-site ushering a new level of interactivity. There is a class of web sites where users don't often install mobile apps but do want a casual subscription to content. For example:

  • News: get notified from sfgate.com on stories around sports teams, restaurant reviews, current events.
  • Consumer: get notified when you've been outbid on ebay.com
  • Consumer: get notified when a specific item is posted on craigslist.org
  • Messaging: get notified when you get a message on IRCcloud, even when Firefox is closed.
  • Enterprise: While working on your laptop, get notified you have a sales lead on salesforce.com
  • Games: get notified that it's your turn in a Facebook scrabble game.
