`vue/component-definition-name-casing`

Enforce PascalCase or kebab-case for component definition names

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.

The component filename is checked. PascalCase and kebab-case are accepted; mixed casing is reported.

Configuration (Vite+)

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

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

vp run lint

Bad

The filename myComponent.vue mixes a lowercase initial with an internal uppercase letter instead of using PascalCase or kebab-case.

myComponent.vue

<template><p>Content</p></template>

Good

Renaming the file to MyComponent.vue uses PascalCase; its template content is unchanged.

MyComponent.vue

<template><p>Content</p></template>

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