Why did it take so long for Nuxt4?

Nuxt core team aimed to release Nuxt4 in June of last year (2024).
The delay was primarily due to the postponed release of Nitro3,
and I understand that it was also delayed due to various bug fixes, the main version work of Nuxt Icon, and the release of Nuxt Ui v3.

We can already use Nuxt4!

Actually, as I mentioned in the previous article, if you add the following code to nuxt.config.ts, you can use Nuxt4 perfectly.

// nuxt.config.ts
export default defineNuxtConfig({
  // ...
  future: {
    compatibilityVersion: 4,
  },
  // ...
})

I have already experienced it!
Since last year, I have been using Nuxt4 as a future version, and I have been able to use it stably in the field.
In addition, as I explained in the article below,
I was very satisfied with the fact that it was easy to migrate from Nuxt3 to Nuxt4 with just a simple structure change and some configuration adjustments.

What improvements are included in Nuxt4?

Nuxt4 has the following improvements!

1. A new /app directory structure has been added.
2. useAsyncData and useFetch provide better caching and processing methods.
3. Head and tag optimization provide better SEO performance.
4. Vite environment API is being prepared for introduction.

Originally, it was planned to introduce Nitro3 to Nuxt4, but after Nuxt4 is officially released, Nitro3 will be applied immediately.
This is because Nitro3 is a more stable and advanced version than Nitro2.

So, until when will Nuxt3 be supported?

It seems that the support for Nuxt3 and the upcoming Nuxt4 and Nuxt5 will proceed as follows!
They say that the migration process is becoming easier, which is why they have set such a short period!

Version	Support
Nuxt3	Support until the end of 2025
Nuxt4	Support until mid-2026
Nuxt5	No plans yet

That’s all!

As you can see, Nuxt4 will be officially available soon!
Of course, you can enjoy Nuxt4 now! (?)

See you nuxt! (not next)
