<p>La interfaz <code>Notification</code> de la <a href="https://developer.mozilla.org/en-US/docs/Web/API/Notifications_API">Notifications API</a> se usa para configurar y mostrar notificaciones de escritorio al usuario. La apariencia y las funcionalidad especificas de esta notificacion varia a traves de las distintas plataformas, pero generalmente esta plataformas proveen un camino para proveer informacion al usuario de manera asincronica.</p>

 <p>Assume this basic HTML:</p>

 <pre class="brush: html line-numbers  language-html"><code class="language-html"><span class="tag token"><span class="tag token"><span class="punctuation token">&lt;</span>button</span> <span class="attr-name token">onclick</span><span class="attr-value token"><span class="punctuation token">=</span><span class="punctuation token">"</span>notifyMe()<span class="punctuation token">"</span></span><span class="punctuation token">&gt;</span></span>Notify me!<span class="tag token"><span class="tag token"><span class="punctuation token">&lt;/</span>button</span><span class="punctuation token">&gt;</span></span></code></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 line-numbers  language-js"><code class="language-js"><span class="keyword token">function</span> <span class="function token">notifyMe</span><span class="punctuation token">(</span><span class="punctuation token">)</span> <span class="punctuation token">{</span>

<span class="punctuation token">}</span></code></pre>

 <p>{{EmbedLiveSample('Example', '100%', 30)}}</p>

 <p>In many cases, you don't need to be this verbose. For example, in our <a href="http://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 line-numbers  language-js"><code class="language-js">Notification<span class="punctuation token">.</span><span class="function token">requestPermission</span><span class="punctuation token">(</span><span class="punctuation token">)</span><span class="punctuation token">.</span><span class="function token">then</span><span class="punctuation token">(</span><span class="keyword token">function</span><span class="punctuation token">(</span>result<span class="punctuation token">)</span> <span class="punctuation token">{</span>
  console<span class="punctuation token">.</span><span class="function token">log</span><span class="punctuation token">(</span>result<span class="punctuation token">)</span><span class="punctuation token">;</span>
<span class="punctuation token">}</span><span class="punctuation token">)</span><span class="punctuation token">;</span></code></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 line-numbers  language-js"><code class="language-js"><span class="keyword token">function</span> <span class="function token">spawnNotification</span><span class="punctuation token">(</span>theBody<span class="punctuation token">,</span>theIcon<span class="punctuation token">,</span>theTitle<span class="punctuation token">)</span> <span class="punctuation token">{</span>

 <p>[1] Before Chrome 22, the support for notification followed an <a href="http://www.chromium.org/developers/design-documents/desktop-notifications/api-specification">old prefixed version of the specification</a> and used the {{domxref("window.navigator.webkitNotifications","navigator.webkitNotifications")}} object to instantiate a new notification.</p>

 <p>Before Chrome 32, {{domxref("Notification.permission")}} was not supported.</p>

 <p>Before Chrome 42, service worker additions were not supported.</p>

 <p>Starting in Chrome 49, notifications do not work in incognito mode.</p>

 <p>[2] Prior to Firefox 22 (Firefox OS &lt;1.2), the instantiation of a new notification must be done with the {{domxref("window.navigator.mozNotification", "navigator.mozNotification")}} object through its <code>createNotification</code> method.</p>

 <p>Prior to Firefox 22 (Firefox OS &lt;1.2), the Notification was displayed when calling the <code>show</code> method and supported only the <code>click</code> and <code>close</code> events.</p>

 <p>Nick Desaulniers wrote a <a href="https://github.com/nickdesaulniers/fxos-irc/blob/master/js/notification.js">Notification shim</a> to cover both newer and older implementations.</p>

 <p>One particular Firefox OS issue is that you can <a href="https://github.com/nickdesaulniers/fxos-irc/blob/0160cf6c3a2b5c9fe33822aaf6bcba3b7e846da9/my.js#L171">pass a path to an icon</a> to use in the notification, but if the app is packaged you cannot use a relative path like <code>/my_icon.png</code>. You also can't use <code>window.location.origin + "/my_icon.png"</code> because <code>window.location.origin</code> is null in packaged apps. The <a href="https://developer.mozilla.org/en-US/Apps/Developing/Manifest#origin">manifest origin field</a> fixes this, but it is only available in Firefox OS 1.1+. A potential solution for supporting Firefox OS &lt;1.1 is to <a href="https://github.com/nickdesaulniers/fxos-irc/blob/0160cf6c3a2b5c9fe33822aaf6bcba3b7e846da9/my.js#L168">pass an absolute URL to an externally hosted version of the icon</a>. This is less than ideal as the notification is displayed immediately without the icon, then the icon is fetched, but it works on all versions of Firefox OS.</p>

 <p>When using notifications  in a Firefox OS app, be sure to add the <code>desktop-notification</code> permission in your manifest file. Notifications can be used at any permission level, hosted or above: <code>"permissions": { "desktop-notification": {} }</code></p>

 <p>[3] Safari started to support notification with Safari 6, but only on Mac OSX 10.8+ (Mountain Lion).</p>
