Anyone used KotlinJS with Firebase?
It does not allow me to sortBy on mutableList
More specifically:
children.sortBy{ it.toString() }
generates

var sortWith = Kotlin.kotlin.collections.sortWith_nqfjgj$;
  var wrapFunction = Kotlin.wrapFunction;
  var compareBy$lambda = wrapFunction(function () {
    var compareValues = Kotlin.kotlin.comparisons.compareValues_s00gnj$;
    return function (closure$selector) {
      return function (a, b) {
        var selector = closure$selector;
        return compareValues(selector(a), selector(b));
      };
    };
  });
  var Comparator = Kotlin.kotlin.Comparator;
  function Comparator$ObjectLiteral(closure$comparison) {
    this.closure$comparison = closure$comparison;
  }
  Comparator$ObjectLiteral.prototype.compare = function (a, b) {
    return this.closure$comparison(a, b);
  };
  Comparator$ObjectLiteral.$metadata$ = {kind: Kotlin.Kind.CLASS, interfaces: [Comparator]};

and Firebase complains:

TypeError: wrapFunction is not a function

kotlin_version = '1.1.50' via gradle if it matters

[konsoletyper]

And what about kotlin.js library. Which version are you using?

[konsoletyper]

Seems that you are using new compiler (1.1.50) with old kotlin.js

[naitbit]

I think it is set to same value:
compile "org.jetbrains.kotlin:kotlin-stdlib-js:$kotlin_version"
testCompile "org.jetbrains.kotlin:kotlin-test-js:$kotlin_version"

[konsoletyper]

Please, run ./gradlew dependencies and see which version of kotlin-stdlib-js artifact is used

[naitbit]

compile - Dependencies for source set 'main' (deprecated, use 'implementation ' instead).
\--- org.jetbrains.kotlinkotlin stdlib js1.1.50

testCompile - Dependencies for source set 'test' (deprecated, use 'testImplementation ' instead).
+--- org.jetbrains.kotlinkotlin stdlib js1.1.50
\--- org.jetbrains.kotlinkotlin test js1.1.50
\--- org.jetbrains.kotlinkotlin stdlib js1.1.50

[konsoletyper]

Ok, I don't know then. If you could create a self-contained project that reproduced the problem, I could investigate it myself

[naitbit]

Ok, thank you I'll try.

[naitbit]

Ok, I think you were right that it was about standard lib. I think require('kotlin') simply failed due to path issues and was null. At least on empty non Firebase project it seems to fail similarly if it is not imported.
I now need to figure out how to put kotlin.js in correct path

[naitbit]

Thanks for help 🙂

[naitbit]

Ok I was wrong, Kotlin lib is imported and deployed on Firebase, I can call it. Strange. Maybe the issue is just with Firebase deploy verification, not with the generated js code.
