# Notebook web notifications

Jupyter notebook extension to display a web notification to notify you when the
kernel becomes idle.
This can be useful when running tasks that take more than a couple of seconds
to complete.

The extension has been tested with the most recent versions of Firefox, Chrome
and Safari.

Initially, a button to request notification permissions is shown in the toolbar.
After notification permissions have been granted, this button is replaced by a
dropdown menu with five choices: Disabled, 0, 5, 10 and 30.
To activate notifications, select a minimum kernel busy time required to
trigger a notification (e.g. if selecting 5, a notification will only be shown
if the kernel was busy for more than 5 seconds). The selection is saved in the
notebook's metadata and restored when the notebook is re-opened.

You may configure the plugin so that notifications require manual dismissal
before disappearing. Browser support is limited, see
[here](https://developer.mozilla.org/en-US/docs/Web/API/notification/requireInteraction)
to check if your browser supports this. You may also configure the plugin so
that notifications play a sound.
