A modern programming language that makes developers happier.

kotlinlang

I'm trying to get kotlinjs to work with Firebase cloud functions, but I'm running into an issue when I build my project.

The structure of the project calls for a directory called `/functions` that contains `index.js`, `node_modules`, `package.json` and `package-lock.json`. My source is in `/src/main/kotlin`. Every time I build, `index.js` is correctly put into `/functions` but the other files are deleted. My `build.gradle` file is below. Any one have any advice?

```
plugins {
    id 'kotlin2js' version '1.3.31'
}

group 'com.myapp'
version '1.0.0'

repositories {
    mavenCentral()
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-js"
    testImplementation "org.jetbrains.kotlin:kotlin-test-js"
}

compileKotlin2Js.kotlinOptions {
    moduleKind = "commonjs"
    outputFile = "functions/index.js"
    sourceMap = true
}
```
