`vue/valid-attribute-name`

Require valid attribute names

Default severity: error
Presets: essential, 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.

Bad diagnostic: parser/template

Malformed attribute spelling is diagnosed by parser/template before this defensive rule sees an attribute. Bad therefore reports parser/template; it does not promise a separate vue/valid-attribute-name finding.

Configuration (Vite+)

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

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "vue/valid-attribute-name": "error"
      }
    },
  },
});

vp run lint

Bad

The quote inside my"attr makes the attribute name malformed. This example produces the parser's parser/template diagnostic rather than promising a separate rule diagnostic.

<template>
<div my"attr="value"></div>
</template>

Good

my-attr is a well-formed attribute name, so the template parser can read the attribute and its value.

<template>
<div my-attr="value"></div>
</template>

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