`vue/no-boolean-attr-value`

Disallow explicit values for boolean HTML attributes

Default severity: warning
Presets: nuxt, opinionated
Automatic fix: Available for supported findings
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.

Configuration (Vite+)

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

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "vue/no-boolean-attr-value": "warn"
      }
    },
  },
});

vp run lint

Bad

The boolean disabled and checked attributes redundantly contain string values.

<template>
  <input disabled="disabled" />
  <input checked="checked" />
  <button disabled="true">Save</button>
</template>

Good

The presence of each boolean attribute expresses the same enabled state without a value.

<template>
  <input disabled />
  <input checked />
  <button disabled>Save</button>
</template>

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