is there a good book for nana lib of good tutorial

I've been working on a more detailed alternative for the documentation, that includes examples. It's far from complete, but you may find it useful: https://errorflynn.github.io/nana-docs/ It's not designed for mobile devices at the moment (use desktop to view).
