Babel

For compiling React, first install the Babel React preset module as a development dependency:

npm install babel-preset-react --save-dev

Then, update .babelrc to include the module and also configure the react-hot-loader Babel plugin as required for the react-hot-loader module.

mern-skeleton/.babelrc:

{    "presets": [      "env",      "stage-2",      "react"    ],    "plugins": [      "react-hot-loader/babel"    ]}
