Overview

Nuxt 3 is a complete rewrite of Nuxt 2, and also based on a new set of underlying technologies.

That means there will be significant changes when migrating a Nuxt 2 app to Nuxt 3, although you can expect migration to become more straightforward as we move toward a stable release.

::alert{type=info} This migration guide is under progress to align with the development of Nuxt 3. ::

Some of these significant changes include:

1. Moving from Vue 2 to Vue 3, including defaulting to the Composition API and script setup.
2. Moving from webpack 4 and Babel to Vite or webpack 5 and esbuild.
3. Moving from a runtime Nuxt dependency to a minimal, standalone server compiled with nitropack.
