Function Dir

fs.go:42–50

Dir returns an http.FileSystem that can be used by http.FileServer(). It is used internally in router.Static(). if listDirectory == true, then it works the same as http.Dir(), otherwise it returns a filesystem that prevents http.FileServer() to list the directory files.

(root string, listDirectory bool)

// if listDirectory == true, then it works the same as http.Dir(),
// otherwise it returns a filesystem that prevents http.FileServer() to list the directory files.
func Dir(root string, listDirectory bool) http.FileSystem {
	fs := http.Dir(root)

	if listDirectory {
		return fs
	}

	return &OnlyFilesFS{FileSystem: fs}
