lazysizes
High performance (jankfree) lazy loader for images (including responsive images), iframes and scripts (widgets).
respimage
The fast, lightweight and reliable polyfill for responsive images (i.e. picture element and the srcset, sizes and media attributes). With a smart resource selection algorithm, that saves bandwidth.
lazysizes-umd
Temporary fork of lazysizes which adds UMD wrapper for all plugins for better integration with webpack or browserify.
