Summary:

This PR provides a new feature of extending composables by additional data. Now you can pass some Ref values of any handles to shared composables along with the special addons object.

Defining within the Vue component.

<script setup lang="ts">
import { useSharedState } from '@composables/useSharedState'

const {
  sharedState: { data },
} = useSharedState({ addons: { someRef } })
</script>

Using along within the Vue composable.

export const useSharedState = useStateEffect<{ someRef: Ref }, { state: Ref }>((...args) => {
  const [options] = args
  console.log(options.addons.someRef)

  /* rest of the composable logic */

  return {
    state,
  }
})

Additionally:

• dependencies were updated
• old Vue demo was removed
