`script/no-export-in-script-setup`

Disallow export statements inside <script setup>

Default severity: error
Presets: none
Automatic fix: None; review the suggested change
Applies to: JS/TS scripts in Vue SFCs; examples show the relevant Options API or script setup form
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-export-in-script-setup": "error"
      }
    },
  },
});

vp run lint

Bad

export const count attempts to expose a module export from <script setup>, where runtime exports are prohibited.

<script setup lang="ts">
export const count = 1;
</script>

Good

Removing export keeps count as a setup binding rather than a module export.

<script setup lang="ts">
const count = 1;
</script>

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