<p><span class="seoSummary">The <code>Notification</code> interface of the <a href="/en-US/docs/Web/API/Notifications_API">Notifications API</a> is used to configure and display desktop notifications to the user.</span> These notifications' appearance and specific functionality vary across platforms but generally they provide a way to asynchronously provide information to the user.</p>

<dd>A string representing the current permission to display notifications. Possible values are:
<ul>
<li><code>denied</code> — The user refuses to have notifications displayed.</li>
<li><code>granted</code> — The user accepts having notifications displayed.</li>
<li><code>default</code> — The user choice is unknown and therefore the browser will act as if the value were denied.</li>

<h3 id="Instance_methods">Instance methods</h3>
<p>These properties are available only on an instance of the <code>Notification</code> object or through its <a href="/en-US/docs/Web/JavaScript/Guide/Inheritance_and_the_prototype_chain"><code>prototype</code></a>.

<dl>
<dt>{{domxref("Notification.close()")}}</dt>
<dd>Programmatically closes a notification.</dd>

<h2 id="Example">Example</h2>
<p>Assume this basic HTML:</p>
<pre class="brush: html"><button onclick="notifyMe()">Notify me!</button></pre>
<p>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.</p>
<pre class="brush: js">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.
}</pre>
<p>{{EmbedLiveSample('Example', '100%', 30)}}</p>
<h3 id="Alternate_example_run_on_page_load">Alternate example: run on page load</h3>
<p>In many cases, you don't need to be this verbose. For example, in our <a href="https://mdn.github.io/emogotchi/">Emogotchi demo</a> (<a href="https://github.com/mdn/emogotchi">see source code</a>), 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):</p>
<pre class="brush: js">Notification.requestPermission().then(function(result) {
console.log(result);
});</pre>
<p>Then we run a simple <code>spawnNotification()</code> 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 <code>options</code> object and fires the notification using the {{domxref("Notification.Notification","Notification()")}} constructor.</p>
<pre class="brush: js">function spawnNotification(body, icon, title) {
var options = {
body: body,
icon: icon
};
var n = new Notification(title, options);
}</pre>
