Sasaki's Notification

Pure JS notifications; popups and push enabled.

Documentation

Install

yarn add @strategies/notification

Usage

Unless deferred, all Notification instances will display immediately upon invocation, no assignment required.

import Notification from '@strategies/notification';

new Notification('hello');
new Notification({ message: 'hello' });

Lifecycle

There are two lifecycle methods: .play() and .finish(). All notifications can be replayed instead of having to create a new Notification each time you want to display that notification.

const notification = new Notification('Repeat me');
notification.play();
notification.play();

Attach a click event to a notification

let notification: Notification;
notification = new Notification({
    message: 'I will stay open until clicked',
    duration: Infinity,
    onClick: () => notification.finish(),
});

Deferred notifications

If you want to create notifications to be used later, you can always defer them.

const notification = new Notification({ message: 'Hello', defer: true });

// notification won't play until you tell it to play
notification.play();

Push notifications

If you desire to use the push notification feature of this package, you must supply an empty JS file in your public folder to be used as a Service Worker. By default, this file is ./notification.js.

Configuration

Environment

You can configure the Notification environment statically on the Notification class. Note: these configuration settings are the default values.

Notification.configure({
    mount: document.querySelector('body'),
    serviceWorker: './notification.js',
});

Notifications

You can configure the default settings for all notifications or pass the same configuration options into each Notification instance.

Notification.configure({
    duration: 3000,  // amount of time in milliseconds that a notification will show.
    defer: false,    // if true, notifications will not play upon instantiantion.
    flash: false,    // if true, the latest notification will repeatedly flash in the tab title.
    push: false,     // if true, the notification will appear as a push notification if the tab is not in focus.
});

new Notification({
    message: 'Save Successful',
    duration: 2000,
});
