asyncData()

If you choose not to use setup() in your app, you can use the asyncData() method within your component definition:

<script lang="ts">
export default defineNuxtComponent({
  asyncData () {
    return {
      data: {
        greetings: 'hello world!',
      },
    }
  },
})
</script>

head()

If you choose not to use setup() in your app, you can use the head() method within your component definition:

<script lang="ts">
export default defineNuxtComponent({
  head (nuxtApp) {
    return {
      title: 'My site',
    }
  },
})
</script>
