Learning Nuxt 4.3

Based on the official Nuxt release notes

Here's the honest truth: I use Nuxt every day, but every release ships features I've never actually put my hands on. Nuxt 4.3 is a perfect example — I read the release notes, nodded along, and then kept writing code the old way out of habit.

So this series is me fixing that, and you're coming with me. We're a room full of novices where it counts: we know the framework, we just haven't used these features yet.

Everything here is based on the official Nuxt 4.3 release notes. We're not replacing the docs — we're learning to actually use what they announced.

How this series works#

Each step takes one feature and walks the same path:

  1. What's new — the feature in one breath
  2. Why you'd care — the real problem it solves
  3. Before — how we did it without the feature
  4. After — how we do it now
  5. Do it yourself — hands-on steps you run
  6. Gotchas — what tripped me up
  7. Recap — what to remember
