Vue Accessibility Blueprint: 8 Steps

Updated: at 

Creating accessible Vue components is crucial for building inclusive web applications that work for everyone, including people with disabilities. This guide outlines 8 essential steps to improve the accessibility of your Vue projects and align them with Web Content Accessibility Guidelines (WCAG) standards.

Why Accessibility Matters

Implementing accessible design in Vue apps:

Now let’s explore the 8 key steps for building accessible Vue components:

1. Master Semantic HTML

Using proper HTML structure and semantics provides a solid foundation for assistive technologies. Key actions:

<header>
  <h1>Accessible Blog</h1>
  <nav aria-label="Main">
    <a href="#home">Home</a>
    <a href="#about">About</a>
  </nav>
</header>

<main>
  <article>
    <h2>Latest Post</h2>
    <p>Content goes here...</p>
  </article>

  <form>
    <label for="comment">Comment:</label>
    <textarea id="comment" name="comment"></textarea>
    <button type="submit">Post</button>
  </form>
</main>

2. Use eslint-plugin-vue-a11y

Add this ESLint plugin to detect accessibility issues during development:

npm install eslint-plugin-vuejs-accessibility --save-dev

3. Test with Vue Testing Library

Adopt Vue Testing Library to write accessibility-focused tests:

import { render, screen } from '@testing-library/vue'
import MyComponent from './MyComponent.vue'

test('renders accessible button', () => {
  render(MyComponent)
  const button = screen.getByRole('button', { name: /submit/i })
  expect(button).toBeInTheDocument()
})

4. Use Screen Readers

Test your app with screen readers like NVDA, VoiceOver or JAWS to experience it as visually impaired users do.

5. Run Lighthouse Audits

Use Lighthouse in Chrome DevTools or CLI to get comprehensive accessibility assessments.

6. Consult A11y Experts

Partner with accessibility specialists to gain deeper insights and recommendations.

7. Integrate A11y in Workflows

Make accessibility a core part of planning and development:

8. Automate Testing with Cypress

Use Cypress with axe-core for automated a11y testing:

describe('Home Page Accessibility', () => {
  beforeEach(() => {
    cy.visit('/')
    cy.injectAxe()
  })

  it('Has no detectable a11y violations', () => {
    cy.checkA11y()
  })
})
