How to do WebPack LiveReload on OpenServer?

Question

Yii

Hello to all developers, I worked on a gallop with OpenServer, but somehow I didn’t make friends with him. I want to put a webPack with liverReload, but not the entire page, but only the updated element, and connect all this not just to index.html, but to the entire Yii2 project. With gulp it turned out, I can’t find information on webPack, can someone tell me how to do this? well, or how to update not the entire page in gulp, but only the updated element, because it's a long time to wait for a heavy page to be updated.
