then-events v1.0.0

Node Asynchronous EventEmitter

This is an EventEmitter for NodeJS which works with event listeners which have an awaitable return type. The emit-function is tuned to return a promise which is resolved as soon as all callbacks have finished.

npm i --save then-events

import { AsyncEventEmitter } from "then-events"

const emitter = new AsyncEventEmitter()

emitter.on('foo', () => {
  return new Promise(accept => {
    setTimeout(accept, 100)
  })
})

emitter.emit('foo').then(() => {
  console.log('it is done.')
})
