Configuration (Vite+)

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

export default defineConfig({
  vue: {
    linter: {
      "preset": "incremental",
      "rules": {
        "script/no-deprecated-vue-config-keycodes": "error"
      }
    },
  },
});

vp run lint

Bad

Vue.config.keyCodes.enter assigns a removed key-code alias.

<script setup lang="ts">
Vue.config.keyCodes.enter = 13
</script>

Good

The key code is an ordinary constant, const enter = 13.

<script setup lang="ts">
const enter = 13
</script>

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