Simple Static File Server in Go

serve.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))

Thanks for sharing, this is neat.

an interesting docker image:
https://github.com/patrickdappollonio/http-server

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!
