Installation

Using npm / yarn (recommended)

yarn add chirashi-event-emitter

or

npm i --save chirashi-event-emitter

Now you can import methods in your project:

import EventEmitter from 'chirashi-event-emitter'

const emitter = EventEmitter()
const off = emitter.on('event', (foo, bar) => {
  console.log(foo, bar)
})

emitter.emit('event', 'foo', 'bar')
// logs: foo, bar

off()
emitter.emit('event', 'foo', 'bar')
// won't log anything

Standalone

You can download chirashi-event-emitter.js or chirashi-event-emitter.min.js and load it using a script tag. You can also use CDN version of those files from unpkg using the link https://unpkg.com/chirashi@latest/dist/chirashi-event-emitter.min.js. It'll create an instance of ChirashiEventEmitter on your window. Then use as following example

const emitter = ChirashiEventEmitter()

const off = emitter.on('event', (foo, bar) => {
  console.log(foo, bar)
})

emitter.emit('event', 'foo', 'bar')
// logs: foo, bar

off()
emitter.emit('event', 'foo', 'bar')
// won't log anything
