Do you like see the new notifications count in the LinkedIn browser tab?
In this episode we will update the browser tab title, if the application user has new unsee notifications.
We will use StimulusJS to add a blinking effect.
We will use Turbo Stream Broadcasts to update the notifications count in all browser tabs.
We will also add an undead symbol to the application thumbnail.

In the context of StimulusJS, we will leverage setInterval and usage of disconnect().

Improvements you can do yourself:

  • Scope notifications per user
  • Mark notifications as seen when accessing notifications#show page/controller
  • Broadcast notifications count when notification is deleted or seen
