The Vue warning message indicated a failure in resolving the directive for b-popover

<template>
  <div>
    <div class="text-center my-3">
      <b-button
        v-b-popover.hover="'I am popover content!'"
        title="Popover Title"
        >Hover Me</b-button
      >
    </div>
  </div>
</template>

<script>
import { VBPopover } from "bootstrap-vue";
export default{
  directives: {
    VBPopover
  },
}
<script>

It's puzzling to me why this warning keeps cropping up. Switching v-b-popover.hover with b-popover.hover eliminates the warning, but the intended functionality is not achieved.

I'm attempting to incorporate the popover directive outlined in the documentation:

Answer №1

Directive IDs are automatically prefixed with v-. It is recommended to explicitly set the directive ID as mentioned in the documentation here

directives: {
  'b-popover': VBPopover
}

The issue arose because

directives: {
  VBPopover 
}

is equivalent to

directives: {
  VBPopover: VBPopover
}

resulting in the name VBPopover being transformed to v-b-popover and then receiving an automatic prefix, becoming v-v-b-popover. While this can be used in your template, it may appear odd.

Unlike components, directive names undergo transformation to kebab-case and are prefixed with v-.
