{{APIRef("Web Notifications")}}{{AvailableInWorkers}}{{securecontext_header}}

The Notification interface of the Notifications API is used to configure and display desktop notifications to the user. These notifications' appearance and specific functionality vary across platforms but generally they provide a way to asynchronously provide information to the user.

Constructor

{{domxref("Notification.Notification", "Notification()")}}
Creates a new instance of the Notification object.

Properties

Static properties

These properties are available only on the Notification object itself.

{{domxref("Notification.permission")}} {{readonlyinline}}
A string representing the current permission to display notifications. Possible values are:

Instance properties

These properties are available only on instances of the Notification object.

{{domxref("Notification.actions")}} {{readonlyinline}}
The actions array of the notification as specified in the constructor's options parameter.
{{domxref("Notification.badge")}} {{readonlyinline}}
The URL of the image used to represent the notification when there is not enough space to display the notification itself.
{{domxref("Notification.body")}} {{readonlyinline}}
The body string of the notification as specified in the constructor's options parameter.
{{domxref("Notification.data")}} {{readonlyinline}}
Returns a structured clone of the notification’s data.
{{domxref("Notification.dir")}} {{readonlyinline}}
The text direction of the notification as specified in the constructor's options parameter.
{{domxref("Notification.lang")}} {{readonlyinline}}
The language code of the notification as specified in the constructor's options parameter.
{{domxref("Notification.tag")}} {{readonlyinline}}
The ID of the notification (if any) as specified in the constructor's options parameter.
{{domxref("Notification.icon")}} {{readonlyinline}}
The URL of the image used as an icon of the notification as specified in the constructor's options parameter.
{{domxref("Notification.image")}} {{readonlyinline}}
The URL of an image to be displayed as part of the notification, as specified in the constructor's options parameter.
{{domxref("Notification.renotify")}} {{readonlyinline}}
Specifies whether the user should be notified after a new notification replaces an old one.
{{domxref("Notification.requireInteraction")}} {{readonlyinline}}
A {{jsxref("Boolean")}} indicating that a notification should remain active until the user clicks or dismisses it, rather than closing automatically.
{{domxref("Notification.silent")}} {{readonlyinline}}
Specifies whether the notification should be silent — i.e., no sounds or vibrations should be issued, regardless of the device settings.
{{domxref("Notification.timestamp")}} {{readonlyinline}}
Specifies the time at which a notification is created or applicable (past, present, or future).
{{domxref("Notification.title")}} {{readonlyinline}}
The title of the notification as specified in the first parameter of the constructor.
{{domxref("Notification.vibrate")}} {{readonlyinline}}
Specifies a vibration pattern for devices with vibration hardware to emit.

Event handlers

{{domxref("Notification.onclick")}}
A handler for the {{event("click")}} event. It is triggered each time the user clicks on the notification.
{{domxref("Notification.onclose")}}
A handler for the {{event("close")}} event. It is triggered when the user closes the notification.
{{domxref("Notification.onerror")}}
A handler for the {{event("error")}} event. It is triggered each time the notification encounters an error.
{{domxref("Notification.onshow")}}
A handler for the {{event("show")}} event. It is triggered when the notification is displayed.

Methods

Static methods

These methods are available only on the Notification object itself.

{{domxref("Notification.requestPermission()")}}
Requests permission from the user to display notifications.

Instance methods

These properties are available only on an instance of the Notification object or through its prototype. The Notification object also inherits from the {{domxref("EventTarget")}} interface.

{{domxref("Notification.close()")}}
Programmatically closes a notification.

Example

Assume this basic HTML:

<button onclick="notifyMe()">Notify me!</button>

It's possible to send a notification as follows — here we present a fairly verbose and complete set of code you could use if you wanted to first check whether notifications are supported, then check if permission has been granted for the current origin to send notifications, then request permission if required, before then sending a notification.

function notifyMe() {
  // Let's check if the browser supports notifications
  if (!("Notification" in window)) {
    alert("This browser does not support desktop notification");
  }

  // Let's check whether notification permissions have already been granted
  else if (Notification.permission === "granted") {
    // If it's okay let's create a notification
    var notification = new Notification("Hi there!");
  }

  // Otherwise, we need to ask the user for permission
  else if (Notification.permission !== "denied") {
    Notification.requestPermission().then(function (permission) {
      // If the user accepts, let's create a notification
      if (permission === "granted") {
        var notification = new Notification("Hi there!");
      }
    });
  }

  // At last, if the user has denied notifications, and you
  // want to be respectful there is no need to bother them any more.
}

Alternate example: run on page load

In many cases, you don't need to be this verbose. For example, in our Emogotchi demo (see source code), we simply run {{domxref("Notification.requestPermission")}} regardless to make sure we can get permission to send notifications (this uses the newer promise-based method syntax):

Notification.requestPermission().then(function(result) {
  console.log(result);
});

Then we run a simple spawnNotification() function when we want to fire a notification — this is passed arguments to specify the body, icon, and title we want. Then it creates the necessary options object and fires the notification using the {{domxref("Notification.Notification","Notification()")}} constructor.

function spawnNotification(body, icon, title) {
  var options = {
      body: body,
      icon: icon
  };
  var n = new Notification(title, options);
}
