yarn add eventstop

You can also use the UMD version via https://unpkg.com/eventstop

const eventstop = require('eventstop')

const {on, emit} = eventstop()

// subscribe an event
const off = on('ready', msg => {
  console.log('message:', msg)
})

emit('ready', 'hola')
//=> hola

// unsubscribe
off()

const event = eventstop()
// or
const {on, off, emit, once} = eventstop()

Return a function which would execute off(event, handler) when you call it.

You can use * as event type to listen all types:

on('*', (type, foo, bar) => {
  console.log(type, foo, 'and', bar)
  //=> hello you and me
})
emit('hello', 'you', 'me')

In wildcard listener, the first argument of handler function is its type.

Like .on but only trigger handler once.

Type: string

Type: function

Type: string

Same args to .on
