yaemit-extras v0.1.1

yaemit-extras

Extras for a microscopic and speedy event emitter.

npm --save install yaemit yaemit-extras

Usage

Run an event handler once:

import Emitter from 'yaemit'
import { once } from 'yaemit-extras'

const OEmitter = once(Emitter)
const o = new OEmitter()

o.once('event', handler)
o.emit('event') // Ran event handler
o.emit('event') // Didn't run anything

Enable chaining:

import { chain } from 'yaemit-extras'

const CEmitter = chain(Emitter)
const c = new CEmitter()

c.emit('one').emit('two').emit('three')

Emit events when .on and .off are used:

import { notify } from 'yaemit-extras'

const NEmitter = notify(Emitter)
const n = new NEmitter()

n.on('off', () => console.log('off'))
n.off('off') // Runs console.log('off')

Combine mixins:

const SEmitter = once(chain(Emitter))
const spiffy = new SEmitter()

spiffy
  .emit('spaghetti') // Didn't run anything
  .once('spaghetti', handler)
  .emit('spaghetti') // Ran event handler
  .emit('spaghetti') // Didn't run anything
