Example

<html>
<body>
  <div id="app"></div>
  <script src="https://unpkg.com/vue@latest"></script>
  <script src="https://cdn.jsdelivr.net/npm/vue3-sfc-loader/dist/vue3-sfc-loader.js"></script>
  <script>

    const options = {
      moduleCache: {
        vue: Vue
      },
      async getFile(url) {
        
        const res = await fetch(url);
        if ( !res.ok )
          throw Object.assign(new Error(res.statusText + ' ' + url), { res });
        return {
          getContentData: asBinary => asBinary ? res.arrayBuffer() : res.text(),
        }
      },
      addStyle(textContent) {

        const style = Object.assign(document.createElement('style'), { textContent });
        const ref = document.head.getElementsByTagName('style')[0] || null;
        document.head.insertBefore(style, ref);
      },
    }

    const { loadModule } = window['vue3-sfc-loader'];

    const app = Vue.createApp({
      components: {
        'my-component': Vue.defineAsyncComponent( () => loadModule('./myComponent.vue', options) )
      },
      template: '<my-component></my-component>'
    });

    app.mount('#app');

  </script>
</body>
</html>

vue3-sfc-loader.js = Webpack( @vue/compiler-sfc + @babel )

more details

load the .vue file
parse and compile template, script and style sections (@vue/compiler-sfc)
transpile script and compiled template to es5 (@babel)
parse scripts for dependencies (@babel/traverse)
recursively resolve dependencies
merge all and return the component
