title: webpack 4 disable uglifyjs-webpack-plugin
body: <p>I have had <a href="https://stackoverflow.com/questions/51243247/webpack-4-and-uglify-plugin-typeerror-cannot-read-property-length-of-undefin">this</a> problem for the last 2 days. So I decided to completely disable <code>uglifyjs-webpack-plugin</code> from webpack build process. I was not able to find anything on webpack 4.</p>
