How do you ensure Vue component accessibility using eslint-plugin-vue-a11y and ARIA attributes?
❓ Interview Prompt: Explain web accessibility (a11y) in Vue, dynamic ARIA bindings (:aria-expanded), keyboard focus management, and ESLint a11y tools.
Building accessible (a11y) Vue components ensures screen readers and keyboard-only users can navigate your application effectively.
Best Practices:
1
Dynamic ARIA Bindings: Bind ARIA attributes to reactive state: ':aria-expanded="isOpen"', ':aria-controls="dropdownId"'.
2
Keyboard Navigation: Attach keyboard event filters: '@keyup.escape="closeModal"'.
3
Automated Linting: Integrate 'eslint-plugin-vue-a11y' to flag missing 'alt' tags or non-interactive element click handlers during development.
Code Implementation Example
html
<script setup>
import { ref } from 'vue';
const isOpen = ref(false);
</script>
<template>
<button
:aria-expanded="isOpen"
aria-controls="menu-list"
@click="isOpen = !isOpen"
@keyup.escape="isOpen = false">
Toggle Menu
</button>
<ul id="menu-list" v-show="isOpen">...</ul>
</template>💡Dynamic ARIA attribute binding and keyboard accessibility in Vue.
🎯 Interview Key Takeaway
Bind dynamic ARIA attributes (:aria-expanded) and use keyboard event filters to build accessible Vue components.
