This plugin provides babel 7 support to mrbuilder. It allows for configuration via .babelrc or via normal mrbuilder configuration methods. It also provides support for babel to webpack via babel-loader

If your upgrading from babel 6 and have a custom .babelrc try running babel-upgrade to convert your .babelrc. If your using mrbuilders defaults it should "just work".

The default babel configuration:

{
  "presets": [
    "@babel/preset-env",
    "@babel/preset-react"
  ],
  "plugins": [
    "mrbuilder-plugin-babel/react-class-display-name",
    "@babel/plugin-proposal-function-bind",
    "@babel/plugin-proposal-class-properties",
    "@babel/plugin-transform-async-to-generator",
    [
      "@babel/plugin-proposal-export-default-from",
      "@babel/plugin-proposal-export-namespace-from"
    ],
    "@babel/plugin-transform-runtime",
    "@babel/plugin-syntax-dynamic-import",
    "@babel/plugin-syntax-import-meta",
