title: How to not extract CSS into separate files in vue-cli3?
body: <p>In the vue-cli3 project, while we building the project, it seems that it would separate the project into  <code>js</code> file and <code>css</code> file automatically by <code>mini-css-extract-plugin</code>. But now I just want only <code>js</code> file. So I think I need to turnoff <code>mini-css-extract-plugin</code> in <code>vue.config.js</code>.</p>
  
  <p>I want to know how to do it, thanks for ur help.</p>
