SockJS is a JavaScript library (for browsers) that provides a WebSocket-like object. SockJS gives you a coherent, cross-browser, Javascript API which creates a low latency, full duplex, cross-domain communication channel between the browser and the web server, with WebSockets or without. This necessitates the use of a server, which this is one version of, for GO.
SockJS-Go is a Node.js server side counterpart of SockJS-client browser library written in CoffeeScript.
To install sockjs-go run:
go get github.com/igm/sockjs-go/sockjs
A simplified echo SockJS server could look more or less like:
package main
import (
"github.com/igm/sockjs-go/sockjs"
"log"
"net/http"
)
func main() {
sockjs.Install("/echo", EchoHandler, sockjs.DefaultConfig)
err := http.ListenAndServe(":8080", nil)
log.Fatal(err)
}
func EchoHandler(conn sockjs.Conn) {
for {
if msg, err := conn.ReadMessage(); err == nil {
go conn.WriteMessage(msg)
} else {
return
}
}
