Hi All,

 

I want to implement lazy loading for JS and CSS file in AEM component just like image lazy loading.

 

I want to load JS and CSS file when i am scrolling page. Suppose i am scrolling page and in that page below  component JS and CSS file call will come at that time in network tab.

 

 

Thanks,

Niraj.

Hi @user00181  You can try something similar

$( window ).scroll(function() {
    $(window).scrollTop() > 30) {
        await loadScript("js/myscript.js");
    }
});

Hope this helps!
