javascript - Expose method creating a web-component using Vue3 - Stack Overflow

I am creating a web-ponent using VueJS 3, I want to expose a method on the ponent allowing the user to do something like this:

  <custom-ponent id="x1" />

  <script>
    var ponent = document.getElementById("x1");
    
    ponent.customMethod(); // as focus() method on native elements
  </script>

If I define a method on the ponent, I can call the method inside the ponent. But the method is not available when I use it as a web-ponent.

  //main.ts/js
  import { defineCustomElement } from "vue"
  import ponent from "./ponent.ce.vue"

  const element = defineCustomElement(ponent );

  customElements.define("custom-ponent ", element);

  //ponent.ce.vue
  const customMethod = () => { console.log("Executed"); }

How I can indicate to Vue Component Wrapper that the customMethod will be available outside the ponent?

In <script setup>, use the defineExpose() macro:

<script setup>
const customMethod = () => {⋯}
