Hi everyone, I want to convert arraybuffer to byte array, can anyone tell me how to do it?

val fileReader = FileReader()
fileReader.readAsArrayBuffer(Blob(_arrayOf_(file)))
var fileByteArray = ByteArray(file.size.toInt())
val arrayBuffer = fileReader.result as ArrayBuffer

next step is to convert arrayBuffer to byte array in kotlin/js???

[Rafał Kuźmiński]

val result = fileReader.result as ArrayBuffer
val byteArray = Int8Array(result).unsafeCast<ByteArray>()

Should do the trick

@Edoardo Luppi Will you add related extensions in PR?

[Edoardo Luppi]

@turansky yes I will tomorrow, didn't have time today

[turansky]

Int8Array.asByteArray method released in pre.616 . unsafeCast isn’t required anymore

[turansky]

fileReader.readAsArrayBuffer(Blob(arrayOf(file)))

JFYI - File is already Blob and it can be like this

fileReader.readAsArrayBuffer(file)
