title: Vue CLI 3 creating lots of '*.hot-update.js' files. How to prevent that?
body: <p>For development purposes i don't use <code>npm run serve</code> because i'm integrating Vue with my backend project. Instead, i wrote my own command in package.json:</p>
  
  <p><code>"dev": "vue-cli-service build --mode development --watch"</code></p>
  
  <p>And it all works great, but it generates tons of webpack's hot-update.js files in my build dist directory and the problem is that they <strong>don't</strong> get deleted. </p>
  
  <p>Is there a way to configure vue-cli/webpack in such way that these files are automatically deleted or not even created in the first place?</p>
