`vue/no-unused-components`

Disallow registering components that are not used inside templates

Default severity: warning
Presets: happy-path, nuxt, ecosystem, opinionated
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-unused-components": "warn"
      }
    },
  },
});

vp run lint

Bad

UserAvatar is imported as a component but the template never renders it.

<script setup lang="ts">
import UserAvatar from "./UserAvatar.vue";
</script>

<template>
  <p>{{ user.name }}</p>
</template>

Good

The template renders the imported UserAvatar and passes the user binding.

<script setup lang="ts">
import UserAvatar from "./UserAvatar.vue";
</script>

<template>
  <UserAvatar :user="user" />
</template>

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