eventhandler-stream
Create DOM event handler functions that are streams
It supports event filtering
Example
<!--index.html-->
<body>
<button>Click me</button>
<div id="content"></div>
<script src="bundle.js"></script>
</body>// index.js
var eventhandlerstream = require('eventhandler-stream')
// EXAMPLE 1
var button = document.querySelector('button')
// A function can be passed as an argument
// 1. It consumes the event
// 2. it filters what's not pushed to the callback `push`
function custom (ev, push) { if (ev.type === 'click') push(ev.type) }
var buttonHandler$ = eventhandlerstream(custom)
button.addEventListener('click', buttonHandler$)
buttonHandler$.on('data', function (eventType) { console.log(eventType) })
// EXAMPLE 2
var vdom = require('virtual-dom')
var h = vdom.h
var create = vdom.create
// If no function is passed it defaults to
// `function custom (ev, push) { push(ev) }`
var linkHandler$ = eventhandlerstream()
linkHandler$.on('data', function (event) { console.log(event) })
var template = h('a', { onclick: linkHandler$ }, '> clickEvent2console <')
document.querySelector('#content').appendChild(create(template))Convert index.js to bundle.js with the help of for example browserify
npm install browserify -gbrowserify index.js > bundle.js
