Notifications-library

Notifications-library is a small and simple library in TypeScript to manage a notifications system

Usage

Create an instance of the NotificationCenter

    const notificationCenterObject = new NotificationCenter;

If you want to use a remote system, set the configuration

  const configuration = { fetchUrl: 'anyValidURL1', 
                          createUrl: 'anyValidURL2',               
                          updateUrl:'anyValidURL3' };

  notificationCenterObject.setConfig(configuration);

otherwise you can have a full local system.

You can set the sender of the notifications

  const sender = 'AnyValidSender';
  notificationCenterObject.setSender(sender);
