Auto imports don't work in the script setup template without the options API

[isabolic]

Describe the bug

Auto imports don't work in the script setup template without the options API, I am guessing that this is because export default

Vue components are not registered inside auto-imports.d.ts without export default defineComponent({});

example is in here

CompA is registered while CompB is not

also sometimes you need to restart vite server after adding/removing export default defineComponent({});

I think you may have misunderstood the intention of this package. Its purpose is to allow exported JS functions, consts, etc. from other files to be auto-imported within Vue etc. components -- not the other way around.

To solve the issue you're having, you should use https://github.com/unplugin/unplugin-vue-components which makes Vue components available in other Vue components without requiring explicit imports.
