For my design, I want to have Drupal handle all security and presentation. My backend is an api that returns JSON. All I could find showed Drupal as "headless," where Drupal was the back end.
I am trying to avoid building too much into Drupal and being dependent on it.
Is using Drupal for the frontend and having separate API for the back end possible? It sounds like I have it backwards, but I do not to build everything in Drupal. I want to do all the Database and Business logic outside of Drupal.
Edit: This is for an Intranet where I hit many databases.
