jquery_lazyload - Vanilla JavaScript plugin for lazyloading images

•    Javascript

Lazy Load delays loading of images in long web pages. Images outside of viewport will not be loaded before user scrolls to them. This is opposite of image preloading. This is a modern vanilla JavaScript version of the original Lazy Load plugin. It uses Intersection Observer API to observe when the image enters the browsers viewport. Original code was inspired by YUI ImageLoader utility by Matt Mlinac. New version loans heavily from a blog post by Dean Hume.

lozad

•    Javascript

It is written with an aim to lazy load images, iframes, ads, videos or any other element using the recently added Intersection Observer API with tremendous performance benefits. Existing lazy loading libraries hook up to the scroll event or use a periodic timer and call getBoundingClientRect() on elements that need to be lazy loaded. This approach, however, is painfully slow as each call to getBoundingClientRect() forces the browser to re-layout the entire page and will introduce considerable jank to your website.

yall.js - A fast, flexible, and small image lazy loader!

•    Javascript

yall.js is a featured-packed lazy loading script for <img>, <picture>, <video> and <iframe> elements. It works in all modern browsers including IE11. It uses Intersection Observer where available, but falls back to scroll, touchmove, resize, and orientationchange events where necessary. It can also monitor the DOM for changes using Mutation Observer to lazy load image elements that have been appended to the DOM after initial page render, which may be desirable for single page applications. It can also (optionally) optimize use of browser idle time using requestIdleCallback. To optimize decoding of <img> lazy loading for simple src and srcset use cases, yall.js uses Image.decode where available to decode images asynchronously before adding them to the DOM.
