【react】---react中使用装饰器
-
运行 npm run eject 可以让由create-react-app创建的项目的配置项暴露出来
-
此时,项目中多了一个config文件,并且各个配置文件已经暴露出来了。(运行npm run eject之前,保证本地没有待提交到git的文件)
-
安装babel插件
npm install --save-dev @babel/plugin-proposal-decorators react-app-rewired customize-cra react-scripts @babel/plugin-syntax-jsx
@babel/helper-create-regexp-features-plugin -
修改package.json文件的scripts配置项
"scripts": { - "start": "react-scripts start", + "start": "react-app-rewired start", - "build": "react-scripts build", + "build": "react-app-rewired build", - "test": "react-scripts test", + "test": "react-app-rewired test", }
-
"babel": { "plugins": [ ["@babel/plugin-proposal-decorators", { "legacy": true}] ], "presets": [ "react-app" ] }
-
在项目的根目录下创建config-overrides.js
const{ override,addDecoratorsLegacy} =require('customize-cra'); module.exports=override( addDecoratorsLegacy() );
-
在项目的根目录下创建jsconfig.json
{ "compilerOptions": { "experimentalDecorators": true } }
