react antd 按需加载

新手，在学习react 按需加载antd时一直失败，尝试了几次终于成功了

环境

node :v12.14.1

实现

创建项目

create-react-app antd—demo

进入项目目录

cd antd-demo

拉去react配置文件

yarn eject

拉去react配置文件

yarn eject

安装babel-plugin-import

yarn add  babel-plugin-import --save-dev

安装antd

yarn add antd --save

配置package.json

   "babel": {
        .....
        "plugins": [
            [
                "import",
                {
                    "libraryName": "antd",
                    "style": "css"
                }
            ]
        ]
    }

尝试在app.jsx引入

import React from 'react';
import './App.css';
import { Button } from 'antd';
function App() {
  return (
    <Button>App</Button>
  );
}

export default App;

样式效果
