Instance Events

Objects created with new Notification emit the following events:

Note: 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 this could 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.

Event: ‘reply’ macOS

• event Event

Emitted when the user clicks the “Reply” button on a notification with hasReply: true.

Event: ‘action’ macOS

Event: ‘failed’ Windows

Returns:

• event Event
• error string - The error encountered during execution of the show() method.

Instance Methods

Objects created with new Notification have the following instance methods:

notification.show()

Immediately shows the notification to the user, please note this means unlike the HTML5 Notification implementation, instantiating a new Notification does not immediately show it to the user, 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.

Any of the default sounds (under System Preferences > Sound) can be used, in addition to custom sound files. Be sure that the sound file is copied under the app bundle (e.g., YourApp.app/Contents/Resources), or one of the following locations:

• ~/Library/Sounds
• /Library/Sounds
• /Network/Library/Sounds
• /System/Library/Sounds
