I am currently utilizing the Nuxt 3 / Vue 3 defineProps in conjunction with TypeScript and I am looking to automatically deduce prop types from TypeScript types.
import { User } from '~/types/types'
const props = defineProps({
users: {
type: Array, // User[]?
},
})
How can I ensure that the users prop is of type User[] in this particular scenario?
Implement Vue's PropType
import { PropType } from 'vue'
import { Customer } from '~/types/types'
const properties = defineProps = ({
customers: {
type: Array as PropType<Customer[]>
},
})
Another option is to utilize a pure-type syntax :
import { User } from '~/types/types'
const properties = defineProps<{users:User[], title:string}>()
To set default values, you can use the withDefaults helper function :
const properties = withDefaults(defineProps<{users:User[], title:string}>(),{
users:()=>[],// When working with arrays or objects, use a factory function
title:''
})
