Install
go get gopkg.in/olahol/melody.v1
Example: chat
Using Gin:
package main
import (
"github.com/gin-gonic/gin"
"gopkg.in/olahol/melody.v1"
"net/http"
)
func main() {
r := gin.Default()
m := melody.New()
r.GET("/", func(c *gin.Context) {
http.ServeFile(c.Writer, c.Request, "index.html")
})
r.GET("/ws", func(c *gin.Context) {
m.HandleRequest(c.Writer, c.Request)
})
m.HandleMessage(func(s *melody.Session, msg []byte) {
m.Broadcast(msg)
})
r.Run(":5000")
}
Using Echo:
package main
import (
"github.com/labstack/echo"
"github.com/labstack/echo/engine/standard"
"github.com/labstack/echo/middleware"
"gopkg.in/olahol/melody.v1"
"net/http"
)
func main() {
e := echo.New()
m := melody.New()
e.Use(middleware.Logger())
e.Use(middleware.Recover())
e.GET("/", func(c echo.Context) error {
http.ServeFile(c.Response().(*standard.Response).ResponseWriter, c.Request().(*standard.Request).Request, "index.html")
return nil
})
e.GET("/ws", func(c echo.Context) error {
m.HandleRequest(c.Response().(*standard.Response).ResponseWriter, c.Request().(*standard.Request).Request)
return nil
})
m.HandleMessage(func(s *melody.Session, msg []byte) {
m.Broadcast(msg)
})
e.Run(standard.New(":5000"))
}
Example: gophers
package main
import (
"github.com/gin-gonic/gin"

router.GET("/", func(c *gin.Context) {
http.ServeFile(c.Writer, c.Request, "index.html")
})
router.GET("/ws", func(c *gin.Context) {
mrouter.HandleRequest(c.Writer, c.Request)
})
mrouter.HandleConnect(func(s *melody.Session) {

}
gophers[s] = &GopherInfo{strconv.Itoa(counter), "0", "0"}
s.Write([]byte("iam " + gophers[s].ID))
counter += 1
lock.Unlock()
})
mrouter.HandleDisconnect(func(s *melody.Session) {
lock.Lock()
mrouter.BroadcastOthers([]byte("dis "+gophers[s].ID), s)
delete(gophers, s)
lock.Unlock()
})
mrouter.HandleMessage(func(s *melody.Session, msg []byte) {
p := strings.Split(string(msg), " ")
lock.Lock()
info := gophers[s]
if len(p) == 2 {
info.X = p[0]
info.Y = p[1]
mrouter.BroadcastOthers([]byte("set "+info.ID+" "+info.X+" "+info.Y), s)
}
lock.Unlock()
})
router.Run(":5000")
