Nuxt 2 to Nuxt 3: 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.

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.
