主要记录一下加载的过程

markdown-loader,可以在代码中直接导入md文件，一般md文件被解析为html文件后呈现页面上，

开始

### 重点： ###

这里yarn webpack后 找到入口文件main.js 根据import的导入，根据rules中配置的/md$/ 加载到md文件 然后进行自定义处理，这个时候在控制台上打印的文件输入源![在这里插入图片描述][2020120518400461.png]处理好后返回；

注意这里报了错了

因为loader管道需要最终返回js的代码

修改后

改成这个打包就不会报错了

找到这些过后，接着开发，先安装 yarn add markd --dev  
导入 使用

EMS也可以

继续改进 yarn add html-loader --dev  
配置
