How to embed a YouTube video or any iframe with vue-dompurify-html

I have created a blog project in Nuxt and I am using quill text editor for the description field in my database.

When rendering blog's description from database, I used v-html but I got

34:23 warning 'v-html' directive can lead to XSS attack vue/no-v-html

<span v-html="blog.description"></span>

To remove this warning I used vue-dompurify-html.

<span v-dompurify-html="blog.description"></span>

Now, when I add an embedded video link through my quill editor, dompurify removes the video while rendering. Any ideas on how to whitelist this?

This will allow you to achieve an embedded YouTube video with vue-dompurify-html

<template>
  <div>
    <div v-dompurify-html="test"></div>
  </div>
</template>

<script>
import Vue from 'vue'
import VueDOMPurifyHTML from 'vue-dompurify-html'

Vue.use(VueDOMPurifyHTML, {
  default: {
    ADD_TAGS: ['iframe'], // this one whitelists Youtube
  },
})

/* eslint-disable no-useless-escape */
/* eslint-disable prettier/prettier */

export default {
  data() {
    return {
      test: '<iframe class=\"ql-video\" frameborder=\"0\" allowfullscreen=\"true\" src=\"\https://www.youtube.com/embed/9_MzJ9QkiHU\"></iframe><p><br></p><p><br></p><p>Description</p>'
    }
  }
}
</script>

enter image description here

In case you want to go from

'<iframe class=\"ql-video\" frameborder=\"0\" allowfullscreen=\"true\" src=\"\https://www.youtube.com/embed/9_MzJ9QkiHU\"></iframe><p><br></p><p><br></p><p>Description</p>'

into something more clean (for Vue) like this

"<iframe class='ql-video' frameborder='0' allowfullscreen='true' src='https://www.youtube.com/embed/9_MzJ9QkiHU'></iframe><p><br></p><p><br></p><p>Description</p>"

you can use this method

string.replaceAll('"', "'")
