 **host** - is an optional argument that tells your application where devtools middleware server is running, if you debug your app on your computer you don't have to set this (the default is `http://localhost`), but if you want to debug your app on mobile devices, you might want to pass your local IP (e.g. `http://192.168.1.12`).
 
 **port** - is an optional argument that tells your application on what port devtools middleware server is running. If you use proxy server, you might want to set it to `null` so the port won't be added to connection URL.
