React-delayload NPM

React-DelayLoad

Like Lazyload plugin for jQuery, Delayload is library offering a React component for delay-loading images, and it uses throttle to lower the render cost when scrolling and resizing. Moreover, for raw HTML contents created by HTML editors, the library also offers a function for DOM manipulation using plain javascript, and there is no need to require jQuery.
