#Update This information is still relevant but, just use -> Create React App (get back to coding) it handles all of this for you. https://github.com/facebookincubator/create-react-app.

#TL;DR

Do at least this

new webpack.DefinePlugin({
      'process.env': {
        'NODE_ENV': '"production"'
      }
    })

That's a 77 KB win -> because by default, React is in development mode.

Facebook also recommends UglifyJS to completely remove the extra code present in development mode.

#Note Check the Webpack 2 version here https://github.com/timarney/react-setup/tree/webpack2

#What is this? I started this as an experiment to see how big React is for a production build via Webpack (without gzip etc...)

React and React Dom are split out into a vendors.js file (standalone).

Note this isn't a React Starter boilerplate. It's an experiment to test Webpack settings.
