Using Vue to Build Accessible Apps Without Breaking UX

If you’ve ever shipped a feature and thought “we’ll handle accessibility later,” this one is for you.

This article from Certificates.dev breaks down how to build accessible Vue apps from the start, using semantic HTML, reactive ARIA bindings, and proper focus management instead of patching things after the fact. No hacks, no guesswork.

You’ll see why this approach matters for things like:

• modals and overlays
• router-based navigation
• keyboard-driven interfaces
• dynamic UI updates
• form interactions

It’s a practical guide to making accessibility part of your architecture — so your app works for everyone without slowing you down.

Reactivity Best Practices in Vue Without the Usual Pitfalls

If you’ve ever wrestled with Vue reactivity and thought “why is this not updating,” this one is for you.

This article from Certificates.dev walks you through the patterns that actually make Vue 3 reactivity predictable, from choosing between ref and reactive to understanding computed caching and when watch vs watchEffect makes sense.

You’ll see why these patterns matter for things like:

• managing shared state across composables
• avoiding silent reactivity breaks
• optimizing performance in large datasets
• debugging tricky state updates
• keeping derived state clean and reliable

It’s a solid mental model for writing Vue code that scales – fewer surprises, fewer bugs, and way less time debugging.
