binary data isn't working

[Deins]

Sending binary data returns client error (chrome) "WebSocket connection to 'ws://127.0.0.1:8008' failed: Could not decode a text frame as UTF-8." How can i force relay to use binary websocket frames?

Have you tried setting binaryType = 'arraybuffer' on your WebSocket? I suspect this may be a client-side issue rather than a problem with ws-tcp-relay (it just uses io.Copy).

Client side sends all data as binary for sure. My suspicion is that tcp-ws side is at fault. As it incorrectly sends binary data as text frame. So browser can't decode it as string. Anyways I switched to https://github.com/herenow/wsProxy and it works without problems.

Oh, you're totally right, golang.org/x/net/websocket defaults to sending payloads as text frames (in func (*Conn) Write). I will have to add an option to use binary frames instead.
