In accordance with the old function RFC, Vue3 is set to support TypeScript-only props typing. However, when I tested the following code, it appears not to be working as expected and Props are returning as undefined.
interface MessageProps {
msg: string;
list: any[];
}
export default defineComponent({
name: 'HelloWorld',
setup(props: MessageProps) {
console.log(props)
}
})
Currently, the declaration of props is still necessary, despite the RFC suggesting it's optional. There seems to be no discussion on this specific feature, so I assume it hasn't been implemented yet.
In the interim, specifying the props as demonstrated below should resolve any issues:
export default defineComponent({
// declaration required as of [email protected]
props: {
msg: String,
list: Array,
},
setup(props: MessageProps) { /*...*/ }
})
