Is it possible to set a boolean html attribute (not property) with compose? attr("name", true.unsafeCast<String>()) sets it as name="", whereas it should set it as just name with no empty string value.

Isn't the convention for flag properties to do $name="$name"?

[Big Chungus]

Haven't tried that yet, will give it a go and report back

[shikasd]

attr("name", "true") ?

[Big Chungus]

Nope, that one is read as true even if you pass in false value

I believe it’s because of this behaviour of setAttribute

[Akif Abasov [JB]]

Can you specify your use case?

[Big Chungus]

Setting checked attribute on input element. Here's the end result I'm chasing: <input type="checkbox" checked></input>

And i need that to be an html attribute as opposed to property

[Akif Abasov [JB]]

We will take a look how to manage it.

[Akif Abasov [JB]]

Is workaround clear for you until that? using dom effect.

[Big Chungus]

Yeah, but it's kinda ugly 😀

Correct me if I'm wrong but boolean attribute with space is actually by spec a valid way to switch it "on". Not saying we shouldn't discuss API improvements, just want to see the whole picture

[Big Chungus]

That might be true by spec, but many web frameworks don't follow it and demand empty attr without a value to work
