vue3 集成 Sass

创建全局默认样式
在src 文件夹下 创建 styles 并创建 index.scss 引入到项目

import '@/styles/index.scss'

配置scss 全局变量 @import “./src/styles/variable.scss”; 冒号不能少不然会报错

export default defineConfig({
  plugins: [
    vue(),
    createSvgIconsPlugin({
      // 指定需要缓存的图标文件夹
      iconDirs: [path.resolve(process.cwd(), 'src/assets/icons')],
      // 指定symbolId格式
      symbolId: 'icon-[dir]-[name]',
    })
  ],
  // 配置 @ 导入
  resolve: {
    alias: {
      "@": path.resolve("./src")
    }
  },
  // 配置scss 全局配置变量
  css: {
    preprocessorOptions: {
      scss: {
        javascriptEnabled: true,
        additionalData: '@import "./src/styles/variable.scss";',
      }
    }
  }
})
