Why did you close the issue? Sending bynary data over websockets is an important usecase and it is not described in docs
from boopickle.
I managed to find a solution with
import scala.scalajs.js.typedarray.TypedArrayBufferOps._
but it was not that straitforward to get there, so example will be helpful
from boopickle.
The conversion process used in the Ajax wrapper should work fine for Websocket as well. Note that if WS requires ArrayBuffer and does not accept a view (like Int8Array), then you might have to copy stuff around to get the subarray properly.
def byteBuffer2ajax(data: ByteBuffer) = {
if (data.hasTypedArray()) {
// get relevant part of the underlying typed array
data.typedArray().subarray(data.position, data.limit)
} else {
// fall back to copying the data
val tempBuffer = ByteBuffer.allocateDirect(data.remaining)
val origPosition = data.position
tempBuffer.put(data)
data.position(origPosition)
tempBuffer.typedArray()
}
}
