Nuxt `defineProps` from TypeScript types

Question

I'm using Nuxt 3 / Vue 3 defineProps and TypeScript and want to infer types prop types from TypeScript types.

import { User } from '~/types/types'

const props = defineProps({
  users: {
    type: Array, // User[]?
  },
})

In this example, how do I make the users property be of type User[]?

Answer 1

Using Vue’sPropType

import { PropType } from 'vue'
import { User } from '~/types/types'

const props = defineProps = ({
  users: {
    type: Array as PropType<User[]>
  },
})
