Cannot successfully implement http.Handler
I'm trying to get the following code to compile. I cannot successfully implement my own template handler struct an it results in the following error upon build.
Error:
./main.go:28:46: cannot use templateHandler literal (type *templateHandler) as type http.Handler in argument to http.Handle:
*templateHandler does not implement http.Handler (missing ServeHTTP method)
package main
import (
"html/template"
"log"
"net/http"
"path/filepath"
"sync"
)
// templ represents a single template
type templateHandler struct {
once sync.Once
filename string
templ *template.Template
}
// ServeHTTP handles the HTTP request.
func (t *templateHandler) ServerHTTP(w http.ResponseWriter, r *http.Request) {
t.once.Do(func() {
t.templ = template.Must(template.ParseFiles(filepath.Join("templates", t.filename)))
})
t.templ.Execute(w, nil)
}
func main() {
http.Handle("/", &templateHandler{filename: "chat.html"})
// Start Web Server
if err := http.ListenAndServe(":8080", nil); err != nil {
log.Fatal("ListenAndServe:", err)
}
}

Interface has the following representation.
type Handler interface {
ServeHTTP(ResponseWriter, *Request)
}
You're misspelled with the name. ServerHTTP/ServeHTTP.
