|
|
[](https://godoc.org/github.com/gorilla/websocket)

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

|
|
* [Chat example](https://github.com/gorilla/websocket/tree/master/examples/chat)
|
|
* [Command example](https://github.com/gorilla/websocket/tree/master/examples/command)
|
|

|
### 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/gorilla/websocket
|
|
|
|
### Protocol Compliance
|
|
|
|
The Gorilla WebSocket package passes the server tests in the [Autobahn Test
|
|
Suite](https://github.com/crossbario/autobahn-testsuite) using the application in the [examples/autobahn
|
|
subdirectory](https://github.com/gorilla/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.
