Web Notifications made easy
Overview
The simple-web-notification is a simplified web notifications API with automatic permissions support.
This library requires no external dependencies, however the browser must support the Notification API or have a polyfill available.
See W3 Specification for more information.
Demo
Usage
In order to use the simplified web notification API you first must add the relevant dependencies:
<script type="text/javascript" src="web-notification.js"></script>
Now you can use the API anywhere in your application, for example:
document.querySelector('.some-button').addEventListener('click', function onClick() {
webNotification.showNotification('Example Notification', {
body: 'Notification Text...',
icon: 'my-icon.ico',
onClick: function onNotificationClicked() {
console.log('Notification clicked.');
},
autoClose: 4000 //auto close the notification after 4 seconds (you can manually close it via hide function)
}, function onShow(error, hide) {
if (error) {
window.alert('Unable to show notification: ' + error.message);
} else {
console.log('Notification Shown.');
setTimeout(function hideNotification() {
console.log('Hiding notification....');
hide(); //manually close the notification (you can skip this if you use the autoClose option)
}, 5000);
}
});
});
In case you wish to use service worker web notifications, you must provide the serviceWorkerRegistration in the options as follows:
navigator.serviceWorker.register('service-worker.js').then(function(registration) {
document.querySelector('.some-button').addEventListener('click', function onClick() {
webNotification.showNotification('Example Notification', {
serviceWorkerRegistration: registration,
body: 'Notification Text...',
icon: 'my-icon.ico',
actions: [
{
action: 'Start',
title: 'Start'
},
{
action: 'Stop',
title: 'Stop'
}
],
autoClose: 4000 //auto close the notification after 4 seconds (you can manually close it via hide function)
}, function onShow(error, hide) {
if (error) {
window.alert('Unable to show notification: ' + error.message);
} else {
console.log('Notification Shown.');
setTimeout(function hideNotification() {
console.log('Hiding notification....');
hide(); //manually close the notification (you can skip this if you use the autoClose option)
}, 5000);
}
});
});
});
In case you wish to invoke the permissions API manually you can use the webNotification.requestPermission function.
This function triggers the request permissions dialog in case permissions were not already granted.
//manually ask for notification permissions (invoked automatically if needed and allowRequest=true)
webNotification.requestPermission(function onRequest(granted) {
if (granted) {
console.log('Permission Granted.');
} else {
console.log('Permission Not Granted.');
}
});
When using an AMD loader (such as RequireJS) or CommonJS type loader, the webNotification object is not automatically defined on the window scope.
