Publication notifications for static sites

I have a new mini-project for this site: notifications about new pages. Here’s how it will work:

  1. This site will ask users for permission to display notifications.
  2. This site will install a service worker.
  3. The service worker will periodically check the /sitemap.xml for this site. It will store the last seen state. (This could also work with an RSS feed but I haven’t set one up.)
  4. When the service worker detects a new page in the sitemap, it will download it and extract some OpenGraph tags for it.
  5. The service worker will display a notification with the page title, image, etc.

I don’t even know if this is possible. But if I can make a purely static notifications system, it would be pretty cool.

I wrote this because I felt like it. This post is not associated with my employer.
