asynciterify

Turn an event stream into an async iterable

Installation

yarn add @mattkrick/asynciterify

WARNING! This is not transpiled to ES5 because the performance penalty is so high. If you need to target old browsers, include it in your webpack/rollup build!

What is it

A wrapper that turns event streams into async iterables

Why?

Because callbacks are ugly. Seriously, that's the only reason.

Usage

// from this
document.addEventListener('click', (event) => console.log('click')

// to this
import asynciterify from '@mattkrick/asynciterify'

const clicks = asynciterify(document, 'click')
for await (const event of clicks) {
  console.log('click')
}

API

const asyncIterable = asynciterify(source, event, options)

• source: any source like a DOM element, websocket, event emitter, etc.
• event: the event name that you want to listen to, e.g. 'click', 'message', 'data'
• options:
  • isEmitter: defaults to false. If true, it uses on/off methods instead of addEventListener, removeEventListener (useful for EventEmitters)
