vue学习——集成sass

安装

pnpm i sass sass-loader -D

在vite.config.ts文件配置:

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

创建三个文件

src/styles/index.scss // 公共样式
src/styles/reset.scss // 清除默认样式
src/styles/variables.scss // 设置全局变量

// index.scss
@import './reset.scss'; // 注意：分号不能少！

// reset.scss
// 去npm中搜索reset.scss放到这里

去App.vue中测试一下，是否已清除默认样式，全局变量是否生效。
