I want to learn how to build fast and effective webapps with Nodejs and its modules. But the whole system is so confusing and I don't even know where to start and what to use..

I want to build a webapp which uses several different databases (MariaDB) and users (session). The user first choose which website is the right one for him/her and then (s)he logging into that database (app will save the choice). After login the user see only that website's calendar and his/her own information. The user's id should be stored to app or browser so next time when the user uses the app (s)he is already in (no login needed). The user can change his/hers information and use the calendar (both need database connection).So what is the most effective and simplistic way to do this? Which modules to use? I'm PHP coder, so I can read code and I know SQL pretty well, but I don't have much experience about JavaScript or Nodejs.All help is appreciated.
