A modern programming language that makes developers happier.

kotlinlang

my kotlinjs `.js.map` files do not seems to work, as in .. when i open the debugger in chrome the files are empty
i use `moduleKind = "umd"` and require.js to load all things (because everything else seemed to be unproportional more effort)
anybody else having this issue.. or have working source mappings ?

I suppose, that it can be related with <https://youtrack.jetbrains.com/issue/KT-32319>
It plans to be fixed in next eap
In this issue, there is workaround for this problem

it seems to also still work with dce in the mix

do you how to minify the code more without loosing source mapping ?

Now source maps is inlined to final bundle
You can patch webpack configuration in `webpack.config.d`
Something like this
```
config.devtool='source-map'
```
It locates source maps in separate file

i have zero experience using webpack, i kinda hoped to just call a script that translates js in one folder and spits it into another folder

Oh, sorry, I miss that you use only DCE w/o webpack
Manipulation with source maps is hard, because there is relative path in it

i am currently experimenting with uglifyjs used via cli, i read somewhere it can read sourcemaps and generates them
so far not much luck

If source maps are generated by compiler and/or Kotlin/JS DCE, it can be related with UglifyJS issues. Sorry, can’t help with it, because have never tried this tool chain
AFAIK UglifyJS is not supported yet, you can try Terser instead

bash script for terser cli:
```
#!/usr/bin/env bash

./gradlew runDceClient-jsKotlin
OUTPUT=build/html/js/
rm -rf $OUTPUT
mkdir $OUTPUT
FILES=build/kotlin-js-min/client-js/main/*.js
for f in $FILES
do
  if [[ "$f" == *.meta.js ]]; then continue; fi
  echo "Processing $f file..."
  terser $f --source-map "content='$f.map',url='$b.map'" -c -m -o $OUTPUT/$(basename $f)
done
```
