Stream ArrayBuffer websocket binary.js

Question

I want so stream a lot of ArrayBuffers.

Sending Strings from the client to the server and back is no problem!
Sending ArrayBuffer to the Server is no Problem

Sending an ArrayBuffer from server to client is not working. I get an empty ArrayBuffer on the client => ArrayBuffer{}

Server:

var server = BinaryServer({port: 9000});
server.on('connection', function(client){
       client.on('stream', function(stream, meta){
       console.log(meta);
            stream.on('data', function(data){
                //console.log(data);
                stream.write(data);
            });
      });  
});

the console.log(data) shows me the filled array, so this works.

Client:

var wsStream = null;
var client = BinaryClient('ws://localhost:9000');
client.on('open', function(){
    wsStream = client.createStream("audio");

    wsStream.on('data', function(data){
          console.log(data);
    });
});

this logs: ArrayBuffer {}

so no data :(

I send the data with: wsStream.write(arrayBuffer);

If i send some array wsStream.write([0,2]); or some string wsStream.write("Hello"); I have no problem and get all my data back.

why is this happening ? thanks :)

Found a the solution by setting client.binaryType = "arraybuffer"; — Cracker0dks

Problem solved by setting binaryType to arraybuffer.

var myWebSocket = new WebSocket("ws://127.0.0.1");
myWebSocket.binaryType = "arraybuffer";
