go 1.0 includes a http server & util for serving files with a few lines of code.
package main
import (
"fmt"; "log"; "net/http"
)
func main() {
fmt.Println("Serving files in the current directory on port 8080")
http.Handle("/", http.FileServer(http.Dir(".")))
err := http.ListenAndServe(":8080", nil)
if err != nil {
log.Fatal("ListenAndServe: ", err)
}
}
