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

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",

Bad

A non-loop template wrapper has a key even though it is not the keyed iteration boundary.

<template>
<template :key="section"><div>Details</div></template>
</template>

Good

The key belongs to a template v-for iteration, where it identifies each repeated fragment.

<template>
<template v-for="item in items" :key="item.id"><div>{{ item.name }}</div></template>
</template>

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