Class: Notification
Create OS desktop notifications
Process: Main
Notification
is an EventEmitter.
It creates a new Notification
with native properties as set by the options
.
Static Methods
The Notification
class has the following static methods:
Notification.isSupported()
Returns boolean
- Whether or not desktop notifications are supported on the current system
new Notification([options])
Instance Events
Objects created with new Notification
emit the following events:
Some events are only available on specific operating systems and are labeled as such.
Event: 'show'
Returns:
event
Event
Emitted when the notification is shown to the user. Note that this event can be fired
multiple times as a notification can be shown multiple times through the
show()
method.
Event: 'click'
Returns:
event
Event
Emitted when the notification is clicked by the user.
Event: 'close'
Returns:
event
Event
Emitted when the notification is closed by manual intervention from the user.
This event is not guaranteed to be emitted in all cases where the notification is closed.
On Windows, the close
event can be emitted in one of three ways: programmatic dismissal with notification.close()
, by the user closing the notification, or via system timeout. If a notification is in the Action Center after the initial close
event is emitted, a call to notification.close()
will remove the notification from the action center but the close
event will not be emitted again.
Event: 'reply' macOS
Returns:
event
Eventreply
string - The string the user entered into the inline reply field.
Emitted when the user clicks the "Reply" button on a notification with hasReply: true
.
Event: 'action' macOS
Returns:
event
Eventindex
number - The index of the action that was activated.
Event: 'failed' Windows
Returns:
event
Eventerror
string - The error encountered during execution of theshow()
method.
Emitted when an error is encountered while creating and showing the native notification.
Instance Methods
Objects created with the new Notification()
constructor have the following instance methods:
notification.show()
Immediately shows the notification to the user. Unlike the web notification API,
instantiating a new Notification()
does not immediately show it to the user. Instead, you need to
call this method before the OS will display it.
If the notification has been shown before, this method will dismiss the previously shown notification and create a new one with identical properties.
notification.close()
Dismisses the notification.
On Windows, calling notification.close()
while the notification is visible on screen will dismiss the notification and remove it from the Action Center. If notification.close()
is called after the notification is no longer visible on screen, calling notification.close()
will try remove it from the Action Center.
