json wcag accessibility security express javascript

I've been banging my head against this for hours... Currently developing an application that handles sensitive user data alongside ensuring that it meets WCAG compliance standards. This involves providing accessible JSON output for screen readers and other assistive technologies. The challenge arises when implementing security features such as JWT authentication and ensuring that our JSON responses do not compromise accessibility. I've set up a basic Express.js server and created routes that return user data in JSON format. Here’s a simplified version: ```javascript app.get('/api/user', (req, res) => { const user = { id: 1, name: 'Jane Doe', email: 'jane.doe@example.com', roles: ['admin', 'user'] }; res.json(user); }); ``` To enhance accessibility, I've been trying to structure my JSON responses to include clear and descriptive keys, but I'm not sure if this is enough for WCAG compliance. For instance, should I include metadata about the structure of the data or any additional context that could assist users with disabilities? Additionally, I'm using middleware for JWT verification, but I’m concerned that it might introduce complexities in error handling that could affect the user experience. For example, if authentication fails, I want the error message to be understandable and accessible: ```javascript app.use((err, req, res, next) => { if (err.name === 'UnauthorizedError') { return res.status(401).json({ error: 'You need to log in to access this resource.' }); } next(err); }); ``` Could anyone share best practices or patterns for structuring JSON responses that are both secure and accessible? Are there tools or techniques I should consider to ensure my application adheres to WCAG guidelines while maintaining robust security features? Any insights into how to effectively balance these concerns would be greatly appreciated. Is this even possible? This is my first time working with Javascript 3.9. I recently upgraded to Javascript 3.10. What would be the recommended way to handle this? I'd really appreciate any guidance on this.
