Configuration (Vite+)

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

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

vp run lint

Bad

The slot directive is on a native <div> or conflicts with other default/named slot declarations.

<template>
  <div v-slot:header></div>
  <MyComponent v-slot v-slot:header />
  <template v-slot:header v-slot:footer />
</template>

Good

Declare a component's default slot on that component, or its named slot on a child <template #header>.

<template>
  <MyComponent v-slot="{ item }">{{ item }}</MyComponent>
  <MyComponent>
    <template #header>Header</template>
  </MyComponent>
</template>

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