mount-vue-component/dist/index.esm.js

a tiny utility to programatically create and mount Vue 3 components - e.g. a Vue.extend replacement

import { createVNode, render } from 'vue';

function mount(component, { props, children, element, app } = {}) {
  let el = element;

  let vNode = createVNode(component, props, children);
  if (app && app._context) vNode.appContext = app._context;
  if (el) render(vNode, el);
  else if (typeof document !== 'undefined' ) render(vNode, el = document.createElement('div'));

  const destroy = () => {
    if (el) render(null, el);
    el = null;
    vNode = null;
  };

  return { vNode, destroy, el }
}

export { mount };
