Off topic: use separate environment for the actual theme

[simplenotezy]

I notice when running vue.js through the WordPress engine, it is a bit slow. I was wondering what the caveats is from running it from a different domain/server/environment?

Like, how would you handle CSRF-tokens, authentication, and so forth?

I know this might be a bit off topic since you created the project because you'd like to host it on same environment, but nevertheless, I guess you must have some experience.
