Give a TypeScript interface: `interface Foo { foo?: integer | string }`how might I represent this in Kotlin with KXS?

My first inclination is to use
interface Foo { foo: SealedFoo? }
with StringFoo(value: String) : SealedFoo and IntegerFoo(value: Int) : SealedFoo but maybe there is something better.

I'm affraid not. PLus you;ll have to manage wrapping/unwrapping on kotlin side before passing the underlying values to js

I don't like my solution but I have it working with a JsonTransformationPolymorphicSerializer. An idea I have not worked out yet is to use foo: Any? with Int and String getting registered using @Contextual but I don't grok that yet.

fwiw, SealedClassSerializer showed me how to do my original better with a very slight tweak, enclosing the subclasses.
