vanilla-lazyload is a JavaScript lazy loading library and viewport-based asset loader designed to improve page load speed by deferring the loading of images, videos, iframes, and backgrounds. It functions as an intersection observer media loader that triggers resource downloads and script execution only when elements enter the browser viewport. The project also serves as a native lazy loading polyfill, utilizing native browser loading attributes where supported and providing a JavaScript fallback for older environments. The library distinguishes itself through active bandwidth management, suc
layzr.js is a JavaScript image lazy loading library designed to improve initial page load speed by delaying the download of images until they enter the browser viewport. It functions as a responsive image selector that identifies the most appropriate image source based on browser support and device pixel ratio. The library employs a system for responsive image delivery that evaluates data attributes to select optimal sources. It includes a mechanism for dynamic content tracking, which monitors the document for newly added images to ensure they are automatically added to the loading queue. Th
Responsively-lazy is a library designed to optimize web performance by deferring the loading of off-screen assets until they are required by the user. It functions as a utility for reducing initial page payloads by delaying the rendering of images, background images, and HTML content until elements enter the browser viewport. The library distinguishes itself through its automated handling of dynamic content. By utilizing a mutation observer, it monitors the document tree for new elements added after the initial page load and applies lazy loading behaviors to them without requiring manual re-i
This project is a React lazy loading component designed to improve frontend performance by deferring the rendering of child elements until they enter the browser viewport. It functions as a resource lifecycle manager and visibility trigger, preventing unnecessary mounts of off-screen components to reduce initial page load times and memory usage. The library provides configuration for visibility triggers, allowing the use of custom offsets and specific scroll containers to determine when a component loads. It includes mechanisms for managing component lifecycles, enabling the choice of whether
