Babel

系统内置babel处理如下：

• ignore: .min.js
• presets:
  • @babel/preset-env
  • @babel/preset-react (for react)
• plugins:
  • babel-plugin-transform-vue-jsx (for vue)
  • @babel/plugin-proposal-decorators
  • @babel/plugin-proposal-export-namespace-from
  • @babel/plugin-syntax-dynamic-import
  • @babel/plugin-proposal-class-properties
  • @babel/plugin-proposal-json-strings
  • @babel/plugin-transform-runtime
