Switching script code to composition API(setup) in Vue3

I have implemented the code below in a page.

<script>
export default {
  name: 'FaqSection',
  props: {
    content: {
      type: Object,
      required: true,
    },
  },
  data() {
    return {
      scrollArgs: {
        behavior: 'smooth', block: 'start', inline: 'nearest',
      },
    };
  },
  methods: {
    scroll(name) {
      const collapseElement = document.querySelector(name);
      const collapseElementPosition = collapseElement.getBoundingClientRect();
      const windowHeight = document.documentElement.clientHeight;
      if (collapseElementPosition.bottom > windowHeight) {
        collapseElement.scrollIntoView(this.scrollArgs);
      }
    },
  },
};
</script>

What is the process of updating it from Vue's Options API to the Composition API <script setup lang="ts">

Answer №1

https://vuejs.org/guide/introduction.html#composition-api

<script setup lang="ts">
import { ref } from 'vue';
// Reorganize code: 
// - Move 'components' to the top
// - Move 'props' to 'defineProps' macro
// - Move 'data', 'component' and 'method' to the top level

// Define Props using the 'defineProps' macro:
defineProps<{
  content: {}; // Record<string | number | symbol, any>
}>();

const scrollArgs = ref({
  behavior: 'smooth',
  block: 'start',
  inline: 'nearest',
});
function scroll(name) {
  const collapseElement = document.querySelector(name);
  const collapseElementPosition = collapseElement.getBoundingClientRect();
  const windowHeight = document.documentElement.clientHeight;
  if (collapseElementPosition.bottom > windowHeight) {
    collapseElement.scrollIntoView(scrollArgs.value); // .value in <script> is required
  }
}

// Define Options using the 'defineOptions' macro:
defineOptions({
  name: 'FaqSection',
});
</script>
