Regarding Gulp Build

I would like to enquire if this gulp app is able to static host? My understanding is about when we run the gulp serve there is a .tmp hidden file being temporary created and serve from there as it can be found in devRelease file.

Therefore when we do a gulp build and expect it to work on the static host, it does not make sense which is possible without browser sync and ..etc, how can it be done?

Please advise
