Codeigniter API + Vue Front project in same folder

Not sure you can do that (putting them in the same folder), normally you would be serving your vue app with something like nuxtjs somewhere else, sometimes even on a separate IP especially for SEO as the web crawlers need something to hit first time round, but to be honest I've never bothered to use it like that.

I always tend to use Codeigniter with vuejs as a cdn that way there's less to worry about in terms of things like SM, DI and other javascript framework centric paradigms.
