项目中babel-cli的使用

Posted by zhangyingji on April 14, 2018

项目初始化

npm init

项目中安装babel

npm install babel-cli --save-dev

安装相关babel插件

# babel-preset-xxxxxx
npm install babel-preset-es2015 --save-dev

改写package.json

# src:源目录;lib:目标目录
{
  "devDependencies": {
    "babel-cli": "^6.0.0"
  },
  "scripts": {
    "build": "babel src -d lib"
  },
}

根目录下配置文件.babelrc

# presets:转码规则,plugins:插件
{
    "presets": [],
    "plugins": []
}

转码,src转码后的文件在lib下

npm run build
