vue中scss的配置

定义全局变量

// sidebar
$menuText:#bfcbd9;
$menuActiveText:#409EFF;
$subMenuActiveText:#f4f4f5; //https://github.com/ElemeFE/element/issues/12951

$menuBg:#304156;
$menuHover:#263445;

$subMenuBg:#1f2d3d;
$subMenuHover:#001528;

$sideBarWidth: 210px;

// the :export directive is the magic sauce for webpack
// https://www.bluematador.com/blog/how-to-share-variables-between-js-and-sass
:export {
  menuText: $menuText;
  menuActiveText: $menuActiveText;
  subMenuActiveText: $subMenuActiveText;
  menuBg: $menuBg;
  menuHover: $menuHover;
  subMenuBg: $subMenuBg;
  subMenuHover: $subMenuHover;
  sideBarWidth: $sideBarWidth;
}

// :export 的作用是可以在js中直接使用他们

在vite中进行全局配置

    css: {
      preprocessorOptions: {
        scss: {
          // 引入 var.scss 这样就可以在全局中使用 var.scss中预定义的变量了
          // 给导入的路径最后加上 ;
          additionalData: '@import "./src/styles/variables.scss";',
        },
      },
      postcss: {
        plugins: [
          {
            postcssPlugin: "internal:charset-removal",
            AtRule: {
              charset: (atRule) => {
                if (atRule.name === "charset") {
                  atRule.remove();
                }
              },
            },
          },
        ],
      },
    },
