Simple Static File Server in Go
/*
Serve is a very simple static file server in go
Usage:
-p="8100": port to serve on
-d=".": the directory of static files to host
Navigating to http://localhost:8100 will display the index.html or directory
listing file.
*/
package main
import (
"flag"
"log"
"net/http"
)
func main() {
port := flag.String("p", "8100", "port to serve on")
directory := flag.String("d", ".", "the directory of static file to host")
flag.Parse()
http.Handle("/", http.FileServer(http.Dir(*directory)))
log.Printf("Serving %s on HTTP port: %s\n", *directory, *port)
log.Fatal(http.ListenAndServe(":"+*port, nil))

It's weird that this exists. I was tired of using python3 -m http.server and decided to create my own. After, I googled to see what's out there, and alas!!

package main

import (
	"flag"
	"log"
	"net/http"
	"path/filepath"
)

var (
	path = flag.String("path", ".", "path to the folder to serve. Defaults to the current folder")
	port = flag.String("port", "8080", "port to serve on. Defaults to 8080")
)

func main() {
	flag.Parse()

	dirname, err := filepath.Abs(*path)
	if err != nil {
		log.Fatalf("Could not get absolute path to directory: %s: %s", dirname, err.Error())
	}

	log.Printf("Serving %s on port %s", dirname, *port)

	err = Serve(dirname, *port)
	if err != nil {
		log.Fatalf("Could not serve directory: %s: %s", dirname, err.Error())
	}

}

func Serve(dirname string, port string) error {
	fs := http.FileServer(http.Dir(dirname))
	http.Handle("/", fs)

	return http.ListenAndServe(":"+port, nil)
}

Thanks!

Does anybody happen to know why browsers try to display the old directory listing, even though the server is now launched from a different directory?

It's the same on my firefox on Linux machine and chrome on my android. If I reopen the page it'll show the old listing, even though it gets 404 if files are accessed. If I open in incognito or new browser, everything is fine and the new listing is loaded.
