antd按需加载

• npm install antd -S
• 在src文件夹下新建config-overrides.js

  const { 
    override, 
    fixBabelImports, 
    addDecoratorsLegacy, 
  } = require("customize-cra");
  
  module.exports = override(
    fixBabelImports("import", {
      //antd按需加载 
      // npm install react-app-rewired customize-cra babel-plugin-import -D
      libraryName: "antd",
      libraryDirectory: "es",
      style: "css"
    }),
    // 配置装饰器
    // npm install -D @babel/plugin-proposal-decorators
    addDecoratorsLegacy(), 
  );
  

  　

• 然后
  • 　　npm install react-app-rewired customize-cra babel-plugin-import -D
• 需要配置装饰器的
  • npm install -D @babel/plugin-proposal-decorators
• 　　最后修改package.js

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