Gorilla WebSocket compared with other packages

github.com/gorilla golang.org/x/net
RFC 6455 Features
Passes Autobahn Test Suite Yes No
Receive fragmented message Yes No, see note 1
Send close message Yes No
Send pings and receive pongs Yes No
Get the type of a received data message Yes Yes, see note 2
Other Features
Compression Extensions Experimental No
Read message using io.Reader Yes No, see note 3
Write message using io.WriteCloser Yes No, see note 3

Notes:

  1. Large messages are fragmented in Chrome's new WebSocket implementation.
  2. The application can get the type of a received data message by implementing a Codec marshal function.
  3. The go.net io.Reader and io.Writer operate across WebSocket frame boundaries. Read returns when the input buffer is full or a frame boundary is encountered. Each call to Write sends a single frame message. The Gorilla io.Reader and io.WriteCloser operate on a single WebSocket message.
