angular-lazy-img

Lightweight lazy load images plugin. Only 1kb after gziping. Pure JavaScript, only Angular as dependency.

Installation

bower install --save angular-lazy-img

Include angular-lazy-img in your HTML.

<script src="<your-bower-components>/angular-lazy-img/angular-lazy-img.js"></script>

Inject the angular-lazy-img module in your application.

angular.module('your.module', [
    'angularLazyImg'
]);

Usage

Just add lazy-img attribute with source to file that you want to lazy load

<img lazy-img='photo.jpeg' />

If you want show spinner put it in src attribute

<img src='spinner.gif' lazy-img='photo.jpeg' />

You want to lazy load background image? No problem, add directive to anything you like and it will handle the rest.

<div lazy-img='photo.jpeg'></div>

If you need to run the image check manually (for example when clicking on tabs that filter your image result), you can trigger it that way:

$rootScope.$emit('lazyImg.runCheck');

Configuration

Inside your config require 'lazyImgConfigProvider' and set custom options.

angular.module('your.module', [
  'angularLazyImg'
]).config(['lazyImgConfigProvider', function(lazyImgConfigProvider){
  scrollable = document.querySelector('#scrollable')
  lazyImgConfigProvider.setOptions({
    offset: 100 // how early you want to load image (default = 100)
    errorClass: 'error' // in case of loading image failure what class should be added (default = null)
    successClass: 'success' // in case of loading image success what class should be added (default = null)
    onError: function(image){} // function fired on loading error
    onSuccess: function(image){} // function fired on loading success
    container: angular.element(scrollable) // if scrollable container is not $window then provide it here
  });
}])
