just the config i use, I’m sure it could be better but it’s worked for me for a while.

example_webpack.config.js

const path = require('path');
const UglifyJsPlugin = require("uglifyjs-webpack-plugin"); 

// see:  https://stackoverflow.com/a/28989476
var webpack = require("webpack");

console.log("the __dirname is: " + __dirname);

module.exports = {
