Can you specify the type of props that are typically passed in the setup function in Vue 3?

I have a question about using a render function inside a setup function. Specifically, I am curious about the type of props within the scope of setup.

import { h, PropType } from 'vue'
export default {
    props: {
        brand: {
            type: Object as PropType<String>
        }
    },
    setup(props) {
        /* Looking to determine the props argument type */
        const count = ref()
        return () => h('div', props.msg + count.value)
    }
}

Answer №1

props are automatically inferred within the setup scope, however, it is recommended to use defineComponent when creating a component:

import { h, defineComponent } from 'vue'
export default defineComponent({
    props: {
        brand: {
            type: String //just use String
        }
    },
    setup(props) {
        /* you can access `props.brand` with the correct type here */
        const count = ref()
        return () => h('div', props.brand + count.value)
    }
})
