Notification.js

Notification.js is a standalone ES6 module that allows you to easily handle several notifications from different types at the same time. It features a lot of options so you can customize it.

Get started

Notification.js handles four different types of notifications : Success, Info, Warning and Error.

The first step for you to get started with Notification.js is to copy both the dist/Notification.min.js and dist/notification.min.css files in your code base, and the img folder anywhere you need. don't forget to give that path to the Notification constructor, so it can find the needed pictures. Once pasted, don't forget to include the style and the script in your HTML page. You're good to go!

Basic usage

To make Notification.js work, you must call for a new notification handler. It will handle all new notifications coming to the stack, with their specificities. Attach preferabkly this handler to the window object, so you can access it from anywhere in your app:

window.notification = new Notification();

Now that the handler is set, you can call for new notifications anywhere, at anytime using the following calls:

window.notification.success({ message: 'Great success!' });
window.notification.info({ message: 'Much info, very text' });
window.notification.warning({ message: 'Snake?' });
window.notification.error({ message: 'Snaaaaaaaake!' });

The message string passed is mandatory. Forget to pass it and you will raise an error in the console.

Advanced usage

The Notification constructor can take an options object with the following attributes :

window.notification = new notification({
    position: 'top-left',
    thickBorder: 'bottom',
    duration: 2000,
    transition: 100,
    maxActive: 5,
    imgPath: '/path/to/img/'
});

The handler is now ready with your custom settings. To call for a new notification, you can still use the typed methods .success(), .info(), .warning() and .error() from Basic Usage, but you can also use the .new() method :

let id = window.notification.new({
   type: 'info', // Mandatory
   title: 'My test notification',
   message: 'My test message.', // Mandatory
   thickBorder: 'top'
   iconless: false,
   closable: true,
   sticky: true,
   renderTo: document.body,
   CBtitle: 'My callback',
   callback: function() {
     alert('Called from My test notification');
   }
});

The only difference with the typed methods is that with the .new() method, you must give it a type beside giving it a message: those are the two required options to create a standard notification. You can also pass this options object to the typed methods.

As for the typed methods, the new() method return the notification ID, in case you want some manual control over your notifications, this is why we store it in the id variable. Using this ID, you can dismiss a specific notification :

window.notification.dismiss(id);

Or dismiss them all :

window.notification.dismissAll();

Finaly, if you want to clear the Notification singleton, use the destroy() method on the handler :

window.notification.destroy();

Further reading

In the doc folder, there is a JSDoc that has been generated. It is highly detailled, so we recommend you to read this documentation if you want to enhance or modify the class itself. There are some example in the src/Notification.html and a sand box so you can try the system and watch all possibilities given by the passed options.

Unit test

The Jasmine framework is used to perform tests (v3.2.1) on Notification.js.

You can test the source code locally by opening the test/SpecRunner.html file ; because Notification.js is a module, you will encounter a CORS error that prevents you to perform the test ; you can either run a local server, or disable a security flag in your browser (mind to re-enable it after test) to bypass this restriction.
