Vize
vize:croquis/cf/undeclared-prop
A parent passes a prop the child does not declare.
Default severity: warning
Applies to: Analyzed component graph and the supported facts described below
Automatic fix: None; review related files and apply the repair
Options: No per-code options; supported CLI findings accept severity overrides
The experimental Rust CrossFileAnalyzer has a producer for this code. The CLI pass does not emit this individual code; configuring its ID does not enable that Rust pass. These scenarios describe the analyzer's supported graph/facts, not a Vite+ promise.
Shared project files
Use these unchanged files in both Bad and Good. Install the imported packages in the project: Vue, plus vue-router or Pinia where shown. Follow any version-specific support note. The entry root makes the component relationship explicit.
main.ts
import { createApp } from "vue";
import Root from "./App.vue";
createApp(Root).mount("#app");
index.html
<div id="app"></div>
<script type="module" src="/main.ts"></script>
Bad
The parent passes typo even though the resolved child declares only title. This analyzer convention is separate from Vue's general fallthrough-attribute behavior.
App.vue
<script setup lang="ts">
import Child from "./Child.vue";
</script>
<template><Child title="Hello" :typo="true" /></template>
Child.vue
<script setup lang="ts">
const props = defineProps<{ title: string }>();
</script>
<template><p>{{ props.title }}</p></template>
Good
Remove the unintended typo binding and retain the declared title prop.
App.vue
<script setup lang="ts">
import Child from "./Child.vue";
</script>
<template><Child title="Hello" /></template>
Child.vue
<script setup lang="ts">
const props = defineProps<{ title: string }>();
</script>
<template><p>{{ props.title }}</p></template>
The Good files demonstrate the change described above; other diagnostics can still apply to the complete project.
