observe-resize

Trigger a callback when an element is resized. Adapted from simple-element-resize-detector.

Usage

var observeResize = require('observe-resize')
var html = require('bel')
 
var el = html`<div>hello planet</div>`
document.body.appendChild(el)
 
// observers should only be added _after_ the element is rendered on the DOM,
// else it displeases the browser emperors and they _will_ warn you
var stop = observeResize(el, function () {
  console.log('resized')
  stop()
})

API

stopObserving = observeResize(el, callback)

Observe resize events on the specified element. This event is throttled by requestAnimationFrame. In most cases you'd probably still want to use a debounce function to throttle changes, as resize events can be rather volatile otherwise.

stopObserving

Unbind the observer from the element.

Installation

$ npm install observe-resize
