nuxt

3.15.2 is the next regularly scheduled patch release.

👀 Highlights

🔥 Startup performance improvements

It is worth noting that this release includes some pretty significant performance improvements which you should notice particularly in the startup time. In my tests in the nuxt monorepo,

fixture	time to vite build complete (v3.15.1)	time to vite build complete (v3.15.2)
minimal	850ms	710ms
everything bagel	3,021ms	1,690ms

There's more improvement to do here but hopefully these are good numbers!

📦 CLI refactor

To improve performance within Nuxt projects, we've published a new @nuxt/cli distribution of nuxi, which is used under-the-hood in nuxt (see issue). This should behave exactly the same and nothing needs to be updated in your projects (for example, you will continue to use the nuxi or nuxt commands). The only significant change is that it no longer inlines dependencies. Feedback is welcome 🙏

✅ Upgrading

As usual, our recommendation for upgrading is to run:

npx nuxi@latest upgrade --force

This will refresh your lockfile as well, and ensures that you pull in updates from other dependencies that Nuxt relies on, particularly in the unjs ecosystem.
