Use a common accessibility framework to ensure consistency in the accessibility approach across microfrontends. Accessibility is an important aspect of web development that ensures that websites and applications are usable by people with disabilities. Microfrontends are a way of breaking down a large application into smaller, more manageable parts. However, this can lead to inconsistencies in the accessibility approach across the different parts of the application. By using a common accessibility framework, you can ensure that all microfrontends follow the same accessibility guidelines and are accessible to all users.

One example of a common accessibility framework is the Web Content Accessibility Guidelines (WCAG). WCAG is a set of guidelines developed by the World Wide Web Consortium (W3C) that provide a framework for making web content more accessible to people with disabilities. WCAG covers a wide range of accessibility issues, including visual, auditory, and cognitive disabilities. By following the WCAG guidelines, you can ensure that your microfrontends are accessible to all users, regardless of their abilities.

// Example of using the WCAG guidelines in a microfrontend
<button aria-label="Search" tabindex="0">
  <svg viewBox="0 0 24 24" width="24" height="24">
    <path fill="currentColor" d="M22.707 21.293l-5.5-5.5a8.5 8.5 0 1 0-1.414 1.414l5.5 5.5a1 1 0 0 0 1.414 0 1 1 0 0 0 0-1.414zM4 10.5a6.5 6.5 0 1 1 13 0 6.5 6.5 0 0 1-13 0z"></path>
  </svg>
</button>

In the above example, we use the WCAG guidelines to make a search button accessible to all users. We use the aria-label attribute to provide a label for the button that is read by screen readers. We also use the tabindex attribute to make the button focusable with the keyboard. Finally, we use an SVG icon to provide a visual representation of the button that is accessible to users with visual disabilities.
