How to display a progress bar while loading single bundled javascript file by webpack? : <p>The question is concerning webpack. After packing almost everything into a single bundle.js which is loaded in index.html, the bundle.js file is about 2M and requires several seconds to load. </p>

<p>I'd like to display a progress bar indicating loading progress while hiding all the content. Only enable user interaction and show the content after loading is done, exactly the one that Gmail is using. </p>

<p>Is it possible to use webpack to do that? How? </p>

<p>Thanks!</p>
