How can vue 3 hooks be used in main.ts?

Question

Vue.js

Hello, in my examples for vue 2 (for pre-rendering) I often use an event
like

new Vue({
  el: '#app',
  router,
  render: h => h(App),
  mounted () {
    document.dispatchEvent(new Event('render-event'))
  }
})

But how can I make the same event on vue 3 + ts right)?

Answer 1
