js.node.stream.Readable and Writable should be interfaces about haxe-js-kit HOT 5 CLOSED

In reality, interfaces don't exist in JS, and Readable / Writable are actual classes (with constructor, etc). That's why they are implemented as extern classes here.
But then Haxe doesn't allow multiple inheritance, which may be your problem...
But it's difficult to say anything without seeing your extern.
Why don't you just extend Writeable ?

Oh yeah, I see, it 'extends' both...
I'll see what I can do :S

from haxe-js-kit.

I've just added Writable.IWritable, Readable.IReadable, as well as EventEmitter.IEventEmitter, so you can now :

extern interface IPNG
implements IReadable
implements IWritable

but it's really not ideal, because your actual extern class PNG will have to implement them anyway, which feels like duplicate code.
But then I don't see any other way...
I'll add Duplex and Transform streams as well, so you can just implements Duplex, which I guess is what you need here

from haxe-js-kit.

I've added Duplex, I think you'd better extern class PNG extends Duplex

from haxe-js-kit.

That was quick :)
Thanks
