`a11y/mouse-events-have-key-events`

Require focus/blur events with mouse events

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.

Configuration (Vite+)

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

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "a11y/mouse-events-have-key-events": "warn"
      }
    },
  },
});

vp run lint

Bad

Preview visibility changes only through mouse enter and leave handlers.

<template>
  <div @mouseenter="showPreview" @mouseleave="hidePreview">Preview</div>
</template>

Good

The same preview actions run on focus and blur, and the button can receive keyboard focus.

<template>
  <button
    type="button"
    @focus="showPreview"
    @blur="hidePreview"
    @mouseenter="showPreview"
    @mouseleave="hidePreview"
  >
    Preview
  </button>
</template>

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