Sample Basic Webpack Config

webpack.config.js

var debug = process.env.NODE_ENV !== "production";
var webpack = require('webpack');

module.exports = {
  context: __dirname,
  devtool: debug ? "inline-sourcemap" : null,
  entry: "./js/scripts.js",
  output: {
    path: __dirname + "/js",
    filename: "scripts.min.js"
  },
  plugins: debug ? [] : [
    new webpack.optimize.DedupePlugin(),
    new webpack.optimize.OccurenceOrderPlugin(),
    new webpack.optimize.UglifyJsPlugin({ mangle: false, sourcemap: false }),
  ],
  module: {
    loaders: [{
      test: /.jsx?$/,
      exclude: /node_modules/,
      loader: 'babel-loader',
      query: {
        presets: ['es2015', 'react']
      }
    }]
  }
};
