Uncaught TypeError: Super expression must either be null or a function

[arianitu]

When I use webpack and do a production build, it breaks in production. Stack points to this library and after I no longer include react-particles-js I do not get this error anymore.

Specifically breaks on }(f.Component);

Does anyone use this with webpack or in production?

This was a bug from terser-webpack-plugin version 1.2.3. See terser/terser#308

We fixed it by running npm install terser-webpack-plugin@latest
