vue/no-unused-script-vars

Disallow unused script variables, imports, and parameters.

Applies to: Vue SFC templates and blocks, with script context where the rule requires it.

Bad

The script setup declares unused, and neither the script nor the template reads it.

<script setup>
const unused = 1;
</script>
<template><p>Welcome</p></template>

Good

The template interpolates unused, so the declared binding is read.

<script setup>
const unused = 1;
</script>
<template><p>{{ unused }}</p></template>

Configuration (Vite+)

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

export default defineConfig({}).withVue({
  linter: {
    "preset": "incremental",
    "rules": {
      "vue/no-unused-script-vars": "warn"
    },
    "ruleOptions": {
      "vue/no-unused-script-vars": {
        "varsIgnorePattern": "^_",
        "argsIgnorePattern": "^_"
      }
    }
  },
});

Then run vp run lint.
