Nuxt's goal is to make web development intuitive and performant with a great Developer Experience in mind.
We made everything so you can start writing
.vue files from the beginning while enjoying hot module replacement in development and a performant application in production with server-side rendering by default.
Nuxt has no vendor lock-in, allowing you to deploy your application everywhere, even on the edge.
Nuxt uses conventions and an opinionated directory structure to automate repetitive tasks and allow developers to focus on pushing features. The configuration file can still customize and override its default behaviors.
- File-based routing: define routes based on the structure of your
pages/directory. This can make it easier to organize your application and avoid the need for manual route configuration.
- Code splitting: Nuxt automatically splits your code into smaller chunks, which can help reduce the initial load time of your application.
- Server-side rendering out of the box: Nuxt comes with built-in SSR capabilities, so you don't have to set up a separate server yourself.
- Auto-imports: write Vue composables and components in their respective directories and use them without having to import them with the benefits of tree-shaking and optimized JS bundles.
- Data-fetching utilities: Nuxt provides composables to handle SSR-compatible data fetching as well as different strategies.
- Zero-config TypeScript support: write type-safe code without having to learn TypeScript with our auto-generated types and
- Configured build tools: we use Vite by default to support hot module replacement (HMR) in development and bundling your code for production with best-practices baked-in.
Nuxt takes care of these and provides both frontend and backend functionality so you can focus on what matters: creating your web application.
Nuxt comes with built-in server-side rendering (SSR) capabilities by default, without having to configure a server yourself, which has many benefits for web applications:
- Faster initial page load time: Nuxt sends a fully rendered HTML page to the browser, which can be displayed immediately. This can provide a faster perceived page load time and a better user experience (UX), especially on slower networks or devices.
- Better accessibility: the content is immediately available on the initial page load, improving accessibility for users who rely on screen readers or other assistive technologies.
- Easier caching: pages can be cached on the server-side, which can further improve performance by reducing the amount of time it takes to generate and send the content to the client.
Overall, server-side rendering can provide a faster and more efficient user experience, as well as improve search engine optimization and accessibility.
As Nuxt is a versatile framework, it gives you the possibility to statically render your whole application to a static hosting with

The Nuxt server engine Nitro unlocks new full-stack capabilities.
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
In production, Nitro builds your app and server into one universal
A Nuxt application can be deployed on a Node or Deno server, pre-rendered to be hosted in static environments, or deployed to serverless and edge providers.
A module system allows to extend Nuxt with custom features and integrations with third-party services.
Nuxt is composed of different core packages:
- Core Engine: nuxt
- Bundlers: @nuxt/vite-builder and @nuxt/webpack-builder
- Command line interface: nuxi
- Server engine: nitro
- Development kit: @nuxt/kit
- Nuxt 2 Bridge: @nuxt/bridge
