How to define component name in Vue3 setup tag? [duplicate]

Declaring Additional Options

The <script setup> syntax provides the ability to express equivalent functionality of most existing Options API options except for a few:

• name
• inheritAttrs
• Custom options needed by plugins or libraries

If you need to declare these options, use a separate normal block with export default:

<script>
  export default {
    name: 'CustomName',
    inheritAttrs: false,
    customOptions: {}
  }
</script>

<script setup>
  // script setup logic
</script>
