New to Ionic Studio


First please excuse me if the following questions are too “basic”, that´s beacuse I´m really new to Ionic Framework.
I need to develop the frontend on an application. I would like to create a PWA so that it can run on the web and mobiles.
Besides the UI, I need to communicate with external databases using REST calls with JSON format
So here are my questions:

  1. Since I have so many projects at hand, I would like to have the most rapid development tools. I´m considering even Ionic Studio for visual develoment. Will it be a good fit for my requirements?
  2. Does Studio supports REACT and VUE?
  3. Do I really need REACT/VUE to develop my app (with my requirements above)?
  4. Does Studio support REST calls to access remote databases?
