title: Website Performance Weak - Chunk formated JS
body: <p>I'm trying to improve the performance of my project and I help myself with the coverage tool.
  The problem is that in my IDE I can't see this code because it's formatted chunk js code. Could semeone tell me where I could find the useless code please ?</p>
  <p>Thanks !</p>

  <p>Edit: Ok after configuring webpack in my vue.config.js file it's a bit better but there is still some useless code.
