vue/no-export-in-script-setup

disallow export in <script setup>

  • ⚙️ This rule is included in all of "plugin:vue/vue3-essential", "plugin:vue/essential", "plugin:vue/vue3-strongly-recommended", "plugin:vue/strongly-recommended", "plugin:vue/vue3-recommended" and "plugin:vue/recommended".

📖 Rule Details

This rule warns ES module exports in <script setup>.

The previous version of <script setup> RFC used export to define variables used in templates, but the new <script setup> RFC has been updated to define without using export. See Vue RFCs - 0040-script-setup for more details.

<script setup>
/* ✓ GOOD */
let msg = 'Hello!'
</script>
<script setup>
/* ✗ BAD */
export let msg = 'Hello!'
</script>

🔧 Options

Nothing.
