Ballyhoo

Bloody simple, super tiny, pub/sub JS events class based on https://davidwalsh.name/pubsub-javascript implemented in ES6, maintained with 100% test coverage. In production since 2016.

Install

via npm:

npm install ballyhoo --save

via yarn:

yarn add ballyhoo

Getting Started

Using this couldn't be easier. Create a new instance:

import Ballyhoo from 'ballyhoo';
const events = new Ballyhoo();

The create the listener / subscriber:

events.on('namespace/event', function(data) {
    //... do something when the event fires
});

note that the on function returns a remove handler, should you wish to unbind it.

const event = events.on('namespace/event', function(data) {
    //... do something when the event fires
});

// remove event
event.remove();

Then publish an event at an appropriate time:

events.emit('namespace/event', {});

You can pass any data you wish along to the handler function when emitting (or publishing an event) via the second argument.
