@babel中使node.js可以支持ES6，jsx语法（create-react-app中配置）
先看下我package.json依赖吧
作者：比国王富有
"dependencies": {
"@babel/cli": "^7.8.4",
"@babel/core": "^7.8.4",
"@babel/node": "^7.8.4",
"@babel/preset-env": "^7.8.4",
..................
}
接下来当然是安装了，此处本人用yarn
yarn add @babel/cli @babel/core @babel/node --save
yarn add @babel/preset-env --save
安装结束后在.babelrc中配置
{
"plugins": [
[
"@babel/plugin-proposal-decorators",
{
"legacy": true
}
],
["import", { "libraryName": "antd", "libraryDirectory": "es", "style": "css" }]
],
"presets": [
"react-app",
"@babel/preset-env"
]
}
在package.json中配置：
"scripts": {
"start": "react-app-rewired start",
"build": "react-app-rewired build",
"test": "react-app-rewired test --env=jsdom",
"server": "babel-node --presets @babel/env server/server.js",
"server_bak": "nodemon server/server.js"
}
yarn 运行
yarn server
