Upgrade your Vue 2 app with the magical powers of Vue 3 Teleport

By utilizing the teleport feature in Vue 3, you can move a component to the body tag with ease:

<template>
  <button @click="modalOpen = true">
    Open full screen modal! (With teleport!)
  </button>
    
  <teleport to="body">
    <div v-if="modalOpen" class="modal">
      <div>
        I'm a teleported modal! 
        (My parent is "body")
        <button @click="modalOpen = false">
          Close
        </button>
      </div>
    </div>
  </teleport>
</template>

<script>
export default {
  data() {
    return { 
      modalOpen: false
    }
  }
};
</script>

This setup renders the modal dialogue within the body tag. Is there a way to achieve similar functionality in Vue 2?

Answer №1

If you're working with Vue 2 and in need of teleportation capabilities, consider leveraging the portal-vue component specifically designed for Vue 2:

To install:

npm i portal-vue --save

Usage:

In your main.js file:

import Vue from "vue"
import PortalVue from 'portal-vue'
Vue.use(PortalVue)
...

Within a child component:

<portal to="destination">
  <p>The content within this slot will appear wherever the <portal-target> named 'destination'
    is placed.</p>
</portal>

In another location:

<portal-target name="destination">
  <!--
  This component can be positioned anywhere within your application.
  The content slotted in the above portal component will show up here.
  -->
</portal-target
