How to remove extra indentation in a JavaScript template?

Question

Template Engines

I think that the problem is not so common due to the fact that most users use React + JSX, Vue and Angular. But often in VanilaJS I write code like this

function getTemplate() {
     const html = `<div>
           <span>Привет</span>
     </div>`;
    return html;
}

I am using webpack. After compressing such code, extra spaces, hyphens and tabs still remain in the html line.
Because of this, the bundle swells a lot. I do not want to throw such small lines into a separate file.
write like this

function getTemplate() {
     const html = `<div>
<span>Привет</span>
</div>`;
    return html;
}

I also don't really want to.
Is there any plugin or setting that would compress such strings?
