Configuration (Vite+)

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

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "vue/valid-v-for": "error"
      }
    },
  },
});

vp run lint

Bad

The loops omit their iteration expression or add an unsupported .stop modifier.

<template>
  <div v-for></div>
  <div v-for=""></div>
  <div v-for.stop="item in items"></div>
</template>

Good

Use item in items or (item, index) of items with a complete iteration expression and the shown keys.

<template>
  <div v-for="item in items" :key="item.id"></div>
  <div v-for="(item, index) of items" :key="index"></div>
</template>

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