vue/prop-name-casing

Enforce a casing for declared prop names

Bad · Good

Default severity: warning
Presets: happy-path, nuxt, ecosystem, opinionated
Automatic fix: None; review the suggested change
Applies to: Vue SFC templates and blocks, with script context where the rule requires it
Options: No rule-specific options. Severity and preset selection are configurable.

Checks declared prop names, not the casing of attributes passed to a child.

Configuration (Vite+)

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

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "vue/prop-name-casing": "warn"
      }
    },
  },
});

vp run lint

Bad

The declared prop name user_name uses underscore-separated spelling.

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

Good

The declaration and its template reference use the camelCase name userName.

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

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