ember-img-lazy

Lazily load images once they enter your viewport.

Uses IntersectionObserver, does not provide a polyfill and loads images immediately if IntersectionObserver is not available.

Usage

{{img-lazy src="smile.png" width=200 height=200 alt="Smile"}}

Configuration

config/environment:

module.exports = function(environment) {
  let ENV = {
    // ...
    'ember-img-lazy': {
      // Don't load images in fastboot, this effectively
      // shows the placeholder image until ember takes over.
      // Default: false
      lazyFastBoot: true,

      // Config passed to IntersectionObserver.
      observerConfig: {
        rootMargin: '50px 0px',
        threshold: 0.01
      }
    }
  }
  // ...
