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({
  async asyncData() {
    return {
      data: {
        greetings: 'hello world!'
      }
    }
  },
})
</script>
