A simple Webpack configuration file

webpack.config.js

import { resolve } from 'path';

module.exports = env => {
  const config = {
    context: resolve('src/js'),
    entry: {
      main: ['babel-polyfill', './app.js'],
    },
    output: {
      path: resolve('public/dist'),
      filename: '[name].js',
      publicPath: '/dist/',
    },
    plugins: [],
    module: {
      rules: [
        {
          test: /\.js$/,
          use: {
            loader: 'babel-loader',
          },
