Configuration (Vite+)

import { defineConfig } from "@vizejs/vite-plugin/vite-plus";

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "vue/require-toggle-inside-transition": "error"
      }
    },
  },
});

vp run lint

Bad

The static child inside <Transition> has no conditional visibility or dynamic selection to trigger an enter/leave change.

<template>
<transition>
<div>content</div>
</transition>
</template>

Good

v-if="show" changes whether the child exists, giving the transition an enter/leave boundary.

<template>
<transition>
<div v-if="show">content</div>
</transition>
</template>

Good avoids this rule's finding under the configuration above; other rules may still report diagnostics.
