Configuration (Vite+)

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

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

vp run lint

Bad

Bare v-memo gives Vue no dependency expression for deciding when to reuse the subtree.

<template>
  <div v-memo></div>
</template>

Good

v-memo="[valueA, valueB]" supplies the dependency array used for memoization.

<template>
  <div v-memo="[valueA, valueB]">{{ label }}</div>
</template>

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