How can you extend a component during the Vue 3 migration process?

I am facing an issue with a component that I have integrated. After migrating the app to Vue3, I encountered an error stating 

'extend' does not exist on type 'typeof import('....')
. This is because global Vue is no longer a new-able constructor, making Vue.extend method obsolete for constructor extension.

I understand the need to use defineComponent instead of Vue.extend, but I am uncertain about the correct implementation. Can someone guide me on how to write it using defineComponent?

const dialogMain = defineComponent({extends: DialogComponent})

Would this be equivalent to using Vue.extend in Vue2? Any assistance would be appreciated.

Answer №1

Did you attempt utilizing the component options as they are?

const DialogMain = defineComponent(DialogComponent)
