Use the Composition API and Nuxt 3's composables for true code re-usability.
A new zero-dependency experience for easy scaffolding and module integration.
Work faster with info and quick fixes right in the browser.
Brand new module development with TypeScript and cross-version compatibility.
Faster build time and smaller bundle size, with no configuration required.
Experience lightning fast HMR by using Vite as your bundler.
Vue 3 is a solid foundation for your next web app.
Built with native TypeScript and ESM - no extra steps required.
We worked for 9 months on Nuxt's new server engine for Nuxt: Nitro . It unlocks new full-stack capabilities to Nuxt server and beyond.
In development, it uses Rollup and Node.js workers for your server code and context isolation. It also generates your server API by reading files in server/api/ and server middleware from server/middleware/ .
In production, it builds your app and server into one universal .output directory. This output is light: minified and removed from any Node.js modules (except polyfills). You can deploy this output on any system supporting JavaScript, from Node.js, Serverless, Workers, Edge-side rendering or purely static.
The output is combined with both runtime code to run your Nuxt server in any environment (including experimental browser Service Workers!) and serve you static files, making it a true hybrid framework for the JAMStack. In addition, a native storage layer is implemented, supporting multi source, drivers and local assets.
The foundation of the Nitro server is rollup and h3 : a minimal http framework built for high performance and portability.

We've worked to make the upgrade as easy as possible between Nuxt 2 and Nuxt 3.
As we've been working on new features for Nuxt 3, we've back-ported some of them to Nuxt 2.
