Shared project files

Use these unchanged files in both Bad and Good. Install the imported packages in the project: Vue, plus vue-router or Pinia where shown. Follow any version-specific support note. The entry root makes the component relationship explicit.

main.ts

import { createApp } from "vue";
import Root from "./App.vue";
createApp(Root).mount("#app");

index.html

<div id="app"></div>
<script type="module" src="/main.ts"></script>

Bad

The parent's <p> contains a resolved child whose root is <div>, producing invalid paragraph/block nesting after composition.

App.vue

<script setup lang="ts">
import Child from "./Child.vue";
</script>
<template><p><Child /></p></template>

Child.vue

<template><div>Block content</div></template>

Good

Use a <section> container that can contain the child's block element; the child stays unchanged.

App.vue

<script setup lang="ts">
import Child from "./Child.vue";
</script>
<template><section><Child /></section></template>

Child.vue

<template><div>Block content</div></template>

The Good files demonstrate the change described above; other diagnostics can still apply to the complete project.
