if I use dukat to convert js to kt for usage with kotlinjs and react,
I get code like:

var onItemSelect: (item: T, event: React.SyntheticEvent<HTMLElement>) -> Unit

where do I get the React.SyntheticEvent<HTMLElement> from? can't find it anywhere as React does not exist...

[turansky]

SyntheticEvent - JS interface (doesn’t exist in runtime)

You can declare it in react package

external interface SyntheticEvent<T: Element>

[Dirk Hoffmann]

well same for anything that Dukat gives mit
React.xxx of something ...

[turansky]

Full SyntheticEvent - https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/react/index.d.ts#L1166

[Dirk Hoffmann]

so I would dukat "compile" this to a .kt file and include it in my project? (or how these things are supposed to work?)

[turansky]

Dukat has known problems
And I use following scheme:
1. Generate declarations by Dukat or write itself
2. Add package react or other (if Dukat used)
3. Copy declarations to subproject
4. PROFIT

well, yes, definitely some problems 🤣

[Dirk Hoffmann]

sorry to bother again ...
where do I get PropTypes stuff from??
e.g.:

typealias ValidationMap<T> = PropTypes.ValidationMap<T>

[turansky]

HTMLWebViewElement can be external abstract class (before Kotlin/JS stdlib update)
It’s class in any case 🙂

P.S. react doesn’t look like valid package

[turansky]

ValidationMap

[turansky]

Valid React package - react

[Dirk Hoffmann]

no, it's just the warning that it starts with a capital letter (took a capital letter, as I thought it might fix the React.xxxEvent<...> stuff
