Notification

Create OS desktop notifications

Process: Main

Using in the renderer process

If you want to show Notifications from a renderer process you should use the HTML5 Notification API

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]) Experimental

  • options Object
    • title String - A title for the notification, which will be shown at the top of the notification window when it is shown
    • subtitle String - (optional) A subtitle for the notification, which will be displayed below the title. macOS
    • body String - The body text of the notification, which will be displayed below the title or subtitle
    • silent Boolean - (optional) Whether or not to emit an OS notification noise when showing the notification
    • icon (String | NativeImage) - (optional) An icon to use in the notification
    • hasReply Boolean - (optional) Whether or not to add an inline reply option to the notification. macOS
    • replyPlaceholder String - (optional) The placeholder to write in the inline reply input field. macOS
    • sound String - (optional) The name of the sound file to play when the notification is shown. macOS
    • actions NotificationAction[] - (optional) Actions to add to the notification. Please read the available actions and limitations in the NotificationAction documentation macOS

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

Returns:

  • event Event
  • reply 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 Event
  • index Number - The index of the action that was activated

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, simply 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.

Playing Sounds

On macOS, you can specify the name of the sound you'd like to play when the notification is shown. 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

See the NSSound docs for more information.
