Default severity: warning
Presets: none
Automatic fix: None; review the suggested change
Applies to: Vue SFC templates and blocks, with script context where the rule requires it
Options: No rule-specific options. Severity and preset selection are configurable.

Configuration (Vite+)

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

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "vue/no-non-component-keep-alive-child": "warn"
      }
    },
  },
});

vp run lint

Bad

KeepAlive conditionally wraps a native div rather than directly caching UserCard.

<template>
  <KeepAlive>
    <div v-if="ready">
      <UserCard />
    </div>
  </KeepAlive>
</template>

Good

The first example makes UserCard the conditional child. The v-show wrapper illustrates a shape outside this conditional-child check, not a promise that the native wrapper is cached.

<template>
  <KeepAlive>
    <UserCard v-if="ready" />
  </KeepAlive>
  <KeepAlive>
    <div v-show="opened">
      <UserCard />
    </div>
  </KeepAlive>
</template>

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