title: What should I use as backend in electron application?
body: <p>I understand I can design the UI with HTML CSS JavaScript or any other frontend framework.
  I even understand that I can connect to any remote API.
  what if I want a standalone application with database. How should I connect to the database ? where should I write my application logic?
  I feel like there is a missing part in electron do I supposed to use a node JS web Framework like Express?
  or I should write all the program logics in pure node JS without using any framework?
  What is the best approach to write electron applications if possible please point me any working example.</p>
