type/require-typed-props

Require type definition for defineProps

Bad · Good

Default severity: warning
Presets: happy-path, nuxt, ecosystem, opinionated
Automatic fix: None; review the suggested change
Applies to: Type information in Vue SFC scripts and templates, for the constructs shown below
Options: No rule-specific options. Severity and preset selection are configurable.

Type-aware checks use the native Corsa runtime and the TypeScript project. typeAware alone does not enable an opt-in rule.

Configuration (Vite+)

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

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "type/require-typed-props": "warn"
      },
      "typeAware": true
    },
  },
});

vp run lint

Bad

The array-only defineProps(["title"]) declares title by name without giving it a type.

<script setup lang="ts">
defineProps(["title"]);
</script>

Good

defineProps<{ title: string }>() gives title an explicit string type instead of a name-only runtime declaration.

<script setup lang="ts">
defineProps<{ title: string }>();
</script>

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