A WebSocket implementation for Go.

Gorilla WebSocket is a Go implementation of the WebSocket protocol.

The Gorilla WebSocket package provides a complete and tested implementation of the WebSocket protocol. The package API is stable.

go get github.com/gorilla/websocket

The Gorilla WebSocket package passes the server tests in the Autobahn Test Suite using the application in the examples/autobahn subdirectory.

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:

Large messages are fragmented in Chrome's new WebSocket implementation.
The application can get the type of a received data message by implementing a Codec marshal function.
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.

Client and server example

This example shows a simple client and server.

The server echoes messages sent to it. The client sends a message every second and prints all messages received.

To run the example, start the server:

$ go run server.go

Next, start the client:

$ go run client.go

The server includes a simple web client. To use the client, open http://127.0.0.1:8080 in the browser and follow the instructions on the page.
