//https://github.com/tylerb/graceful

package main

import (
  "gopkg.in/tylerb/graceful.v1"
  "net/http"
  "fmt"
  "time"
)

func main() {
  mux := http.NewServeMux()
  mux.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) {
    fmt.Fprintf(w, "Welcome to the home page!")
  })

  graceful.Run(":3001",10*time.Second,mux)
}

Another example, using Negroni, functions in much the same manner:

package main

import (
  "github.com/codegangsta/negroni"
  "gopkg.in/tylerb/graceful.v1"
  "net/http"
  "fmt"
  "time"
)

func main() {
  mux := http.NewServeMux()
  mux.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) {
    fmt.Fprintf(w, "Welcome to the home page!")
  })

  n := negroni.Classic()
  n.UseHandler(mux)
  //n.Run(":3000")
  graceful.Run(":3001",10*time.Second,n)
}
