极客react之Ant Design Pro系列快速入门（四）--界面新增

新增界面

1. src/routes文件下新建目录NewPage，进入该目录添加文件
2. 新建界面样式NewPage.less

   [code]@import "~antd/lib/style/themes/default.less";

    

3. 新建页面文件NewPage.js

4. 声明路径动态加载新建界面app/src/common/route.js

   [code]'/new/newpage': {
   component: dynamicWrapper(app, [], () =>
   import('../routes/New/NewPage')
   ),
   },

    

5. 菜单显示该功能 app/src/commom.menu.js

   [code]{
   name: '自定义模块',
   icon: 'form',
   path: 'new',
   children: [
   {
   name: '新功能',
   path: 'newpage',
   },
   ],
   },
