Types

type Browse

type Browse struct {
	Next          httpserver.Handler
	Configs       []Config

}

Browse is an http.Handler that can show a file listing when directories in the given paths are specified.

func (Browse) ServeHTTP

func (b Browse) ServeHTTP(w http.ResponseWriter, r *http.Request) (int, error)

func (b Browse) ServeListing(w http.ResponseWriter, r *http.Request, requestedFilepath http.File, bc *Config) (int, error)

ServeListing returns a formatted view of 'requestedFilepath' contents'.

type Config

	PathScope string // the base path the URL must match to enable browsing
	Fs        staticfiles.FileServer

Config is a configuration for browsing in a particular path.
