how do you handle js objects? looks like you can use interfaces https://kotlinlang.org/docs/js-interop.html#external-interfaces but that looks painful; can you simply use data classes instead?

[Edoardo Luppi]

Nope. The only way to do it without external interface s is via jso<Type> { }, which is very inconvenient as it only allows var properties. @turansky is there a way to allow interfaces with val properties using jso?

With externals you'll be able to use @JsPlainObject since K2.

[Bernhard]

oh, I see

[Bernhard]

it's not documented, it's in the release notes

[turansky]

K2 with @JsPlainObject can be used right now

[Edoardo Luppi]

I guess jso + interface and val would require some kind of error suppression via compiler plugin

[turansky]

jso is for very complex/generic interfaces only and work with val - isn't case for jso

[turansky]

For K2 single jso case - props of html elements

[Edoardo Luppi]

Mmmh last time I used jso I couldn't use val properties, I had to declare everything as var. Did I miss something?

[turansky]

@JsPlainObject :)

[Edoardo Luppi]

Still very much unusable tho. Need proper IDE support

[Bernhard]

how do you handle default values for @JsPlainObject?

[Bernhard]

can't use definedExternally

[Edoardo Luppi]

No, you can't use default values yet.

[Bernhard]

so you need to pass in all values to a function in this case?

[Bernhard]

passing objects to js functions is kinda the solution to named parameters

[turansky]

so you need to pass in all values to a function in this case?

Only non-nullable

[Bernhard]

oh, thank you
