WebsocketProxy

WebsocketProxy is an http.Handler interface build on top of gorilla/websocket that you can plug into your existing Go webserver to provide WebSocket reverse proxy.

Install

go get github.com/koding/websocketproxy

Example

Below is a simple server that proxies to the given backend URL

package main
import (
"flag""net/http""net/url""github.com/koding/websocketproxy"
)
var (
flagBackend=flag.String("backend", "", "Backend URL for proxying")
)
funcmain() {
u, err:=url.Parse(*flagBackend)
iferr!=nil {
log.Fatalln(err)
}
err=http.ListenAndServe(":80", websocketproxy.NewProxy(u))
iferr!=nil {
log.Fatalln(err)
}
}

Save it as proxy.go and run as:

go run proxy.go -backend ws://example.com:3000

Now all incoming WebSocket requests coming to this server will be proxied to ws://example.com:3000
