Anyone using CI with React,Vue,Svelte or Marko?

I use Vue with codeigniter 3.

My codeigniter app is just a json backend at this point. Having a json backend that's not coupled with the front end makes it easier to port applications too (I'm currently converting my CI app to Laravel).

Codeigniter is simply one of the tools you need to learn to be a successful developer. Always add more tools to your coding arsenal!
