打包时资源压缩

1、icon很大大问题
webpack或者umi配置

  alias: {
    '@ant-design/icons/lib/dist$': path.resolve(__dirname, '../src/icons.js')
  }

src下面加一个icon.js

// export what antd other components need
export {
  default as CloseOutline
} from '@ant-design/icons/lib/outline/CloseOutline';

export {
  default as LoadingOutline
} from '@ant-design/icons/lib/outline/LoadingOutline';

还可以用其它方法

moment很大的问题目
全部替换成dayjs还要删除依赖重新build
