windows-notification-state
SHQueryUserNotificationState, implemented as a native Node addon. If you're looking for a simple solution to check whether or not you should send your user a notification, this is it.
npm install windows-notification-state
const { shQueryUserNotificationState, getNotificationState } = require('windows-notification-state`)
// This will print a number (corresponding with QUERY_USER_NOTIFICATION_STATE)
console.log(shQueryUserNotificationState())
// If you prefer your code to be more readable, you can use the string-based variant.
// This will print the name of the enum (so "QUNS_ACCEPTS_NOTIFICATIONS" instead of 5)
console.log(getNotificationState())
