I am trying to use the setup function and the ref but cannot make it work, i am used to work with Vue 3 with this API Components but its not working:

Thanks Toby for the quick answer, I did as suggested but still get an error in Vue:

Whats wrong?

Thanks!

@rafaelsevy Looking at your screenshot, I see that the error is reported by vue-router. Which can mean that you are incorrectly declaring the route. Vue Router explicitly says that the "() => import('...')" syntax is to still be used when lazy loading the component for a route. It does not matter if you wrap the actual component code with defineComponent() or not.

Thank you Razvan, how can I solve this? because no matter where I use this component throws the same error, I can also see this error in my CMD.

It seeems I might be missing to install something

Show us a repo and we can help identify the misusage.

since ref and defineComponent aren't present, i think u're using Quasar v1 + vue 2.
to use the composite APi with vue 2, u'll need to install that package:
