Echo.js is a standalone 2KB JavaScript micro-library for lazy-loading images using HTML5 data-* attributes. It supports lazy-loading of both img tags and background images with configurable offsets and throttled scroll handling.
Use cases
- lazy load images as the user scrolls
- defer loading of below-the-fold images
- lazy load background images via data attributes
- improve page load performance on image-heavy pages
- load images only when they approach the viewport
When to choose
- you need a tiny dependency-free lazy-loading solution for legacy browsers like IE8+
- you want simple data-attribute-based image lazy loading without a framework
When to avoid
- you need modern native loading='lazy' or IntersectionObserver-based solutions
- you need active maintenance or support for modern frameworks
- you need lazy loading of iframes, videos, or other media types
