`vue/no-undefined-refs`

Disallow undefined variable references in templates

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-undefined-refs": "warn"
      }
    },
  },
});

vp run lint

Bad

The template reads missing, although the script declares only message.

<script setup>const message = "Hello";</script>
<template>{{ missing }}</template>

Good

The interpolation reads the existing message binding.

<script setup>const message = "Hello";</script>
<template>{{ message }}</template>

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