Default severity: error
Presets: essential, happy-path, ecosystem, nuxt, opinionated

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": {
        "script/no-ref-as-operand": "error"
      }
    },
  },
});

vp run lint

Bad

count + 1 uses the ref object itself as the arithmetic operand instead of the number it wraps.

<script setup lang="ts">
import { ref } from "vue";
const count = ref(0);
const next = count + 1;
</script>

Good

count.value + 1 reads the wrapped number before adding one; script arithmetic requires this explicit ref access.

<script setup lang="ts">
import { ref } from "vue";
const count = ref(0);
const next = count.value + 1;
</script>

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