Gorilla WebSocket compared with other packages


  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 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.
