How to use TypeScript in Vue3

[hehehai]

Can it be realized?

Are you not able to use the vue3 template? Here's an example https://codesandbox.io/s/template-vue3-7xqjxr?file=/src/App.tsx

I'm sorry. I may not have described it clearly.

like this

<script lang="ts">
import { ref } from "vue";
export default {
   name: "App",
   setup() {
      const helloWorld = ref<string>("Hello World");
      return { helloWorld };
   }
};
</script>
