## Class: Notification
> Create OS desktop notifications
Process: [Main](../glossary.md#main-process)
`Notification` is an
[EventEmitter](http://nodejs.org/api/events.html#events_class_events_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` [NativeImage](native-image.md) - (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_
* `actions` [NotificationAction[]](structures/notification-action.md) - (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 guarunteed 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.
