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.

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.

Installation

Run npm install in your project as follows:

npm install --save simple-web-notification

Or if you are using bower, you can install it as follows:
