antd 组件按需加载

1. 安装react-app-rewired
   npm install [email protected] babel-plugin-import --save

2. 扩展webpack的配置
   2.1.1 在根目录下创建config-overrides.js文件

const { injectBabelPlugin } = require("react-app-rewired");

module.exports = function override(config, env) {
  // antd按需加载
  config = injectBabelPlugin(
    ["import", { libraryName: "antd", libraryDirectory: "es", style: "css" }],
    config
  );
  return config;
};

3. 修改package.json 的启动脚本为react-app-rewired启动

"scripts": {
    "start": "react-app-rewired start",
    "build": "react-app-rewired build",
    "test": "react-app-rewired test",
    "eject": "react-app-rewired eject"
  }
