How to remove dead code, but don't minimize code, using Webpack and UglifyJS?

Three minuses, but not comments, really?

You probably want to use the beautifier options. Minimum idea:

new webpack.optimize.UglifyJsPlugin({ beautify: true })

See github.com/mishoo/UglifyJS2#compressor-options . Esp. dead_code. I read the initial description wrong.

But whai if I only want to remove dead code and leave everything untouched? Beautifier transforms my code in many different ways.

Maybe disable everything else then. I have a feeling Uglify wasn't designed particularly that use case in mind so using that feature alone may be tricky.

I got that feeling too because I already have disabled everything else and it still minimizes (unless I tell it to beutify but as I said before - that also transforms my code)
