How to do it…

1. Install the github.com/gorilla/mux package using the go get command, as follows:

$ go get github.com/gorilla/mux

2. Create serve-static-files-gorilla-mux.go, where we will create a Gorilla Mux router instead of an HTTP FileServer, as follows:

package main
import 
(
  "html/template"
  "log"
  "net/http"
  "github.com/gorilla/mux"
)
const 
(
  CONN_HOST = "localhost"
  CONN_PORT = "8080"
)
type Person struct 
{
  Id string
  Name string
}
func renderTemplate(w http.ResponseWriter, r *http.Request) 
{
  person := Person{Id: "1", Name: "Foo"}
  parsedTemplate, _ := template.ParseFiles("templates/
  first-template.html")
  err := parsedTemplate.Execute(w, person)
  if err != nil 
  {
    log.Printf("Error occurred while executing the template 
    or writing its output : ", err)
    return
  }
}
func main() 
{
  router := mux.NewRouter()
  router.HandleFunc("/", renderTemplate).Methods("GET")
  router.PathPrefix("/").Handler(http.StripPrefix("/static",
  http.FileServer(http.Dir("static/"))))
  err := http.ListenAndServe(CONN_HOST+":"+CONN_PORT, router)
  if err != nil 
  {
    log.Fatal("error starting http server : ", err)
    return
  }
}

3. Run the program with the following command:

$ go run serve-static-files-gorilla-mux.go
