1. 定义 variable.scss 存放全局变量

// base color
$blue:#324157;
$light-blue:#3A71A8;
$red:#C03639;
$pink: #E65D6E;
$green: #30B08F;
$tiffany: #4AB7BD;
$yellow:#FEC171;
$panGreen: #30B08F;

// 默认菜单主题风格
$base-menu-color:#bfcbd9;
$base-menu-color-active:#f4f4f5;
$base-menu-background:#304156;
$base-logo-title-color: #ffffff;

$base-menu-light-color:rgba(0,0,0,.70);
$base-menu-light-background:#ffffff;
$base-logo-light-title-color: #001529;

$base-sub-menu-background:#1f2d3d;
$base-sub-menu-hover:#001528;

$base-sidebar-width: 200px;
 
// 暴露变量名字
:export {
  menuColor: $base-menu-color;
  menuLightColor: $base-menu-light-color;
  menuColorActive: $base-menu-color-active;
  menuBackground: $base-menu-background;
  menuLightBackground: $base-menu-light-background;
  subMenuBackground: $base-sub-menu-background;
  subMenuHover: $base-sub-menu-hover;
  sideBarWidth: $base-sidebar-width;
  logoTitleColor: $base-logo-title-color;
  logoLightTitleColor: $base-logo-light-title-color
}

2. 配置

在vite.config.ts文件配置如下:

export default defineConfig((config) => {
    css: {
      preprocessorOptions: {
        scss: {
          javascriptEnabled: true,
          additionalData: '@import "./src/styles/variable.scss";',
        },
      },
    },
   }
}

@import "./src/styles/variable.less";后面的;不要忘记，不然会报错!

3. 使用

• 直接使用

• 使用暴露的变量名
