# Gorilla WebSocket

Gorilla WebSocket is a [Go](http://golang.org/) implementation of the
[WebSocket](http://www.rfc-editor.org/rfc/rfc6455.txt) protocol.

**NOTE:** This is a fork/vendoring of http://github.com/gorilla/websocket
The following documentation has been modified to point at this fork for
convenience.

### Documentation

* [API Reference](http://godoc.org/github.com/btcsuite/websocket)
* [Chat example](https://github.com/btcsuite/websocket/tree/master/examples/chat)
* [File watch example](https://github.com/btcsuite/websocket/tree/master/examples/filewatch)

### Status

The Gorilla WebSocket package provides a complete and tested implementation of
the [WebSocket](http://www.rfc-editor.org/rfc/rfc6455.txt) protocol. The
package API is stable.

### Installation

    go get github.com/btcsuite/websocket

### Protocol Compliance

The Gorilla WebSocket package passes the server tests in the [Autobahn Test
Suite](http://autobahn.ws/testsuite) using the application in the [examples/autobahn
subdirectory](https://github.com/btcsuite/websocket/tree/master/examples/autobahn).

Notes: 

1. Large messages are fragmented in [Chrome's new WebSocket implementation](http://www.ietf.org/mail-archive/web/hybi/current/msg10503.html).
2. The application can get the type of a received data message by implementing
   a [Codec marshal](http://godoc.org/golang.org/x/net/websocket#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.
