Notification: permission static property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

Note: This feature is available in Web Workers.

The permission read-only static property of the Notification interface indicates the current permission granted by the user for the current origin to display web notifications.

Value

A string representing the current permission. The value can be:

granted

The user has explicitly granted permission for the current origin to display system notifications.

denied

The user has explicitly denied permission for the current origin to display system notifications.

default

The user decision is unknown; in this case the application will act as if permission was denied.

Examples

The following snippet could be used 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.

js
function notifyMe() {
  if (!("Notification" in window)) {
    // Check if the browser supports notifications
    alert("This browser does not support desktop notification");
  } else if (Notification.permission === "granted") {
    // Check whether notification permissions have already been granted;
    // if so, create a notification
    const notification = new Notification("Hi there!");
    // …
  } else if (Notification.permission !== "denied") {
    // We need to ask the user for permission
    Notification.requestPermission().then((permission) => {
      // If the user accepts, let's create a notification
      if (permission === "granted") {
        const 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 anymore.
}
