title: My Vue3 Class Component Typescript application gets slower to compile/build when I import bootstrap
body: <p>I realized that my application was much slower to build with vue-cli (either a build production or a simple dev server).</p>
  <p>I import bootstrap this way in a SCSS file that re-writes some rules that is imported in all my other SCSS components.</p>
  <pre><code>@import &quot;bootstrap/scss/bootstrap&quot;;
  </code></pre>
  <p>Here are the build time comparison screens :</p>
