vuejs / composition-api

A component declared through definecomponent has a defect in type verification.

Perhaps the definition of Data does not apply to all occasions?

I tried to delete the definition of unknown. I found that ComponentPropsOptions still need to accept the generics defined by unknown. Otherwise, the required definition of props will not be recognized, resulting in the attribute being considered optional.

I have explored here for the time being and found no other problems.

I use https://github.com/johnsoncodehk/volar-starter vue2 branch.

I propose this issue because the Class API or Vue.extend performs better.
