func (SPA) ServeHTTP ¶

func (spa SPA) ServeHTTP(w http.ResponseWriter, r *http.Request)

ServeHTTP inspects the URL path to locate a file within the static dir on the SPA handler. If a file is found, it will be served. If not, the file located at the index path on the SPA handler will be served. This is suitable behavior for serving an SPA (single page application). HTML, plaintext and JSON files will NEVER cache to guarantee an always up-to-date app. Will cache JS and CSS files forever since we assume their file names are/contain content hashes.
