How to ensure ARIA roles are appropriately utilized in a React application for WCAG compliance
Currently developing a React application that aims to meet WCAG 2.1 standards. I'm focused on ensuring that ARIA roles are being used correctly to enhance accessibility for screen readers. However, I'm not entirely sure if I’m applying them effectively across my components. For instance, I have a custom button component that looks like this: ```jsx const CustomButton = ({ label, onClick }) => { return <button onClick={onClick}>{label}</button>; }; ``` I’ve read that for buttons, it's generally good practice to ensure that they are recognizable as interactive elements. However, in an effort to make things more flexible, I am thinking of adding a prop to accept different roles. That being said, should I also be managing keyboard interactions or is the native button element sufficient? In another scenario, I’m working with a modal component: ```jsx const Modal = ({ isOpen, onClose }) => { if (!isOpen) return null; return ( <div role="dialog" aria-labelledby="modal-title" aria-describedby="modal-description"> <h2 id="modal-title">Modal Title</h2> <p id="modal-description">Description of the modal</p> <button onClick={onClose}>Close</button> </div> ); }; ``` While I have added `role="dialog"`, I’m uncertain if I'm missing any other attributes that might improve accessibility. I’ve also been considering how to manage focus when the modal opens. Would utilizing `tabindex` help in controlling focus for the first focusable element? I’ve explored libraries like `react-aria` for managing these accessibility concerns but found that it adds complexity in understanding how to integrate them effectively with my existing components. I’m curious if anyone has insights on best practices for implementing ARIA roles and managing focus, specifically in React applications. What strategies or resources would you recommend for ensuring compliance without overly complicating the design? I'm developing on Ubuntu 22.04 with Javascript. Hoping someone can shed some light on this. I'm working on a web app that needs to handle this. I'm open to any suggestions.
