react 高阶组件添加装饰器

1. 安装
   install --save babel-plugin-transform-decorators-legacy
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) {
    // 添加装饰器能力
    config = injectBabelPlugin(
        ["@babel/plugin-proposal-decorators", { legacy: true }],
        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"
  }
