It might be worth looking into these changes and trying to get this project onto the latest version of rollup-plugin-uglify.

If you have a solid test suite and good coverage, a passing build is a strong indicator that you can take advantage of these changes directly by merging the proposed change into your project.

Release Notes

v4 and back to es5

uglify-es is not supported anymore so we returned back to old school uglify-js. If you still want to transpile es6+ try rollup-plugin-terser. Terser is actively developed fork of uglify-es with the new name.

In this version we changed the way to import plugin. Now it looks like this

import { uglify } from 'rollup-plugin-uglify';
export default {

...

plugins: [uglify()]

...

}

To see more prettier errors uglify shows also babel code frame
