Parse error at build/kotlin-js-min/client-js/main/d2v-chord-js.js.map:1,10

an i am not sure if thats a well known error or if i am calling uglifyjs completely wrong

It seems that uglify is trying to parse source map. You can have a look at one of data2viz example: https://github.com/data2viz/data2viz/blob/master/examples/ex-geo/ex-geo-js/webpack.config.js

[Nikky]

so you do not invoke uglifyjs manually at all and webpack does that for you ?

[gaetan]

Exactly

[Nikky]

how do you invoke this?

[Nikky]

i am guessing something like npm pack ?

[Nikky]

i am currently trying to get this to work with the kotlin frontend plugin

[gaetan]

I don't use front-end plugin. I usually have yarn + webpack. I define the scripts in package.json and launch them directly or from gradle.
