webpack.config.prod.js

const package = require('./package.json');

This code seems to be duplicated in your project.

const webpack = require('webpack');

The constant webpack seems to be never used. Consider removing it.

const path = require('path');

const config = {
   entry: './main.prod.js',
   output: {
      path: path.normalize(__dirname + '/build'),

Consider using the path module for constructing paths since they are otherwise not cross-OS compatible.
