That's the way ByteBuffers work. They maintain an internal state of how much of the buffer is actually used. Trimming the created ByteBuffer would require additional copying.
Scala-js-dom 0.8.1 supports sending ByteBuffers over Ajax post using the following code
implicit def byteBuffer2ajax(data: ByteBuffer): InputData = {
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()
}
}
Suppose I need to update the documentation to clarify how to use ByteBuffers :)
