Configuration (Vite+)

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

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "script/require-prop-type-constructor": "error"
      }
    },
  },
});

vp run lint

Bad

The prop declarations use strings "String" and "Number" as runtime types, including inside the constructor array. Those strings are not constructor functions.

<script lang="ts">
export default {
props: {
// The type should be the `String` constructor, not the string "String".
name: "String",
age: { type: "Number" },
id: { type: ["String", "Number"] }
}
}
</script>

Good

The declarations use the actual String and Number identifiers, including the union array [String, Number].

<script lang="ts">
export default {
props: {
name: String,
age: { type: Number },
id: { type: [String, Number] }
}
}
</script>

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