The typescript type definition have some problems. about primevue HOT 2 OPEN

For problem 1, when I change DefineComponent from @primevue/core to vue, the problem fixed.

import type { DefineComponent } from '@primevue/core';

declare const Button: DefineComponent<ButtonProps, ButtonSlots, ButtonEmits>;

to

import type { DefineComponent } from 'vue';

declare const Button: DefineComponent<ButtonProps, ButtonSlots, ButtonEmits>;

from primevue.

Do this you fix only for props. Slots and emits doesn't work anyway.

I found what vue DefineComponent typescript type uses first generic (which is ButtonProps in this case) for another type guards. So, i think fix this issue is replace in @primevue/core type guard DefineComponent:
from

export type DefineComponent<P = {}, S = {}, E = {}, M = {}> = _DefineComponent<P, {}, {}, {}, M & MethodOptions, {}, {}, E & ObjectEmitsOptions, string, PublicProps, Readonly<ExtractPropTypes<P>>, ExtractDefaultPropTypes<P>, SlotsType<S>>;

It require types PublicProps, SlotsType, ExtractDefaultPropTypes, ExtractPropTypes from vue bundle

But i think need to use defineComponent (from primevue team side) in vue files by vue's typescript guide: https://vuejs.org/guide/typescript/overview#definecomponent

from primevue.
