script/no-import-compiler-macros

Disallow importing Vue compiler macros that are auto-imported

Bad · Good

Default severity: error
Presets: essential, happy-path, ecosystem, nuxt, opinionated
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-import-compiler-macros": "error"
      }
    },
  },
});

vp run lint

Bad

The vue import includes defineProps and defineEmits, although these are compiler macros available directly in <script setup>.

<script setup lang="ts">
import { defineProps, defineEmits } from "vue";
const props = defineProps<{ title: string }>();
const emit = defineEmits<{ save: [id: number] }>();
</script>

Good

Removing the macro imports leaves both typed macro calls intact; no runtime import is needed for either declaration.

<script setup lang="ts">
const props = defineProps<{ title: string }>();
const emit = defineEmits<{ save: [id: number] }>();
</script>

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