disposable-event

disposable-event is an npm module built to normalize event registration and disposal. We have often dealt with situations where there are inconsistent ways to add or remove event listeners in different APIs, disposable-event normalizes them all and gives authors a beautiful API

Installation

npm install --save disposable-event

API

function disposableEvent(target, eventName, callback, options): Disposable

Usage

import disposableEvent from 'disposable-event'
import {Server} from 'ws'

// Adding listeners
const eventListeners = []
eventListeners.push(disposableEvent(document, 'click', function() {
  console.log('document was clicked')
}))
eventListeners.push(disposableEvent(document, 'keydown', function() {
  console.log('key was pressed')
}))

const server = new Server()
eventListeners.push(disposableEvent(server, 'error', function(error) {
  console.log('error occured', error)
}))

// Disposing listeners
eventListeners.forEach(disposable => disposable.dispose())
