Hello! How to configure production distibution for JS target to aplly DCE, but keep all names from obfuscation?

[Artem Kobzar]

So, there are two steps, that works on different levels:
1. Inside your build.gradle.kts you need to add the next snippet:

[Artem Kobzar]

tasks.withType<org.jetbrains.kotlin.gradle.targets.js.ir.KotlinJsIrLink> {
   kotlinOptions.freeCompilerArgs += "-Xir-minimized-member-names=false"
}

Thanks!

2. If you also need to keep the same name after the webpack, you need to create a directory inside the root of your module with name webpack.config.d , and add the next file with any name and .js extension:

config.module.optimizations?.minimizer = 
   [new TerserPlugin({ terserOptions: { mangle: false } })].concat(config.module.optimizations?.minimizer ?? [])

@PHondogo there is also a section of the documentation for this case
