Serving the current directory over HTTP with Go

Featured image for sharing metadata for article

I've recently been updating a few lightweight static websites and have wanted to preview the changes locally.

Although I usually reach for python -mhttp.server, it's a bit cumbersome to type, so I wanted something a little shorter. I was thinking of writing a script to make it quicker to type, when I thought - "what if I can do it quicker in Go"?

It turns out, it's blazingly fast to do so, in two lines(!) of code:

package main

import (

func main() {
	http.Handle("/", http.FileServer(http.Dir(".")))
	log.Fatal(http.ListenAndServe("", nil))

That's it! This allows you to serve the current directory that the built binary is executed in over HTTP.

I've wrapped this into a standalone tool just to make it easier to install and run, and I may end up adding some more (limited scope) functionality, while leaving it as lightweight as possible.
