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

Actually if i would use a fullstack or almost fullstack framework/toolkit like CI, ~especially in PHP where we can easly integrate into front end code at server-side(they're trying to advert JS as only logical thing to use in front end and lastly asp.net's blazor)~, i would not want to waste my time trying to handle JWT to auth user instead of using server-side sessions. I am not familiar with SPA user auth. Is there any recommendations?

I am thinking to use JWT in SPA and keep user token with cookie-js to persist it.
