how to deploy on remote server?

[fyenne]

hi, thank you for sharing this awesome notes app to us.
I' m some kind of rookie here, so I wonder how can I deploy this on my personal remote server, say ubuntu. I run "npm start" after clone and install on my ubuntu. and the localhost:3000 is ok, I can use another machine to visit via $my ubuntu's ip:3000$. the problem is, when I try to login via github on $my ubuntu's ip:3000$, it fails, fall back to localhost address, which is not possible to access, can you help me with this? thank you ~
