在vue 中使用 less的教程详解

<script>
  (function (doc, win) {
   var docEl = doc.documentElement,
    resizeEvt = 'orientationchange' in window ? 'orientationchange' : 'resize',
    recalc = function () {
     var clientWidth = docEl.clientWidth;
     if (!clientWidth) return;
     if (clientWidth >= 640) {
      docEl.style.fontSize = '100px';
     } else {
      docEl.style.fontSize = 100 * (clientWidth / 640) + 'px';
     }
    };

   if (!doc.addEventListener) return;
   win.addEventListener(resizeEvt, recalc, false);
   doc.addEventListener('DOMContentLoaded', recalc, false);
  })(document, window);
 </script>

   {
    test: /\.less$/,
    use: [
     "style-loader",
     "css-loader",
     "less-loader"
    ]
   }

<template>
  <div class="box"> <p>header</p> </div>
</template>
