Publish and Subscription class.
const PubSub = require('topic-subscribe');
const pubsub = new PubSub();The browser module will automatically export a new function to jQuery if present. To create a new PubSub instance, simply call the function on a dom query. This will assign a PubSub instance to each item in the collection.
jQuery("div.my-app").pubsub().subscribe("/my-channel", event=>{
// do something
});
jQuery("div.my-app").pubsub(").publish("/my-channel", "hello");
jQuery("div.my-app").pubsub().broadcast("/", "Global message");The jQuery functions return a the original query so actions can be chained. This means an unsubscribe function is not passed back. Unsubscriptions require the use of the unsubscribe function.
jQuery("div").pubsub().unsubscript("/my-channel");
jQuery("div").pubsub().unsubscript(myListener);
