Server	Build full-stack applications with Nuxt's server framework. You can fetch data from your database or another server, create APIs, or even generate static server-side content like a sitemap or a RSS feed - all from a single codebase.	i-ph-computer-tower-duotone

Powered by Nitro

Nuxt's server is Nitro. It was originally created for Nuxt but is now part of UnJS and open for other frameworks - and can even be used on its own.

Using Nitro gives Nuxt superpowers:

• Full control of the server-side part of your app
• Universal deployment on any provider (many zero-config)
• Hybrid rendering

Nitro is internally using h3, a minimal H(TTP) framework built for high performance and portability.

Server Endpoints & Middleware

You can easily manage the server-only part of your Nuxt app, from API endpoints to middleware.

Both endpoints and middleware can be defined like this:

export default defineEventHandler(async (event) => {
  // ... Do whatever you want here
})

And you can directly return text, json, html or even a stream.

Out-of-the-box, it supports hot module replacement and auto-import like the other parts of your Nuxt application.

Universal Deployment

Nitro offers the ability to deploy your Nuxt app anywhere, from a bare metal server to the edge network, with a start time of just a few milliseconds. That's fast!

There are more than 15 presets to build your Nuxt app for different cloud providers and servers, including:

• Cloudflare Workers
• Netlify Functions
• Vercel Edge Network

Or for other runtimes:

::card-group :card{icon="i-logos-deno" title="Deno" to="https://deno.land" target="_blank"} :card{icon="i-logos-bun" title="Bun" to="https://bun.sh" target="_blank"} ::

Hybrid Rendering

Nitro has a powerful feature called routeRules which allows you to define a set of rules to customize how each route of your Nuxt app is rendered (and more).

export default defineNuxtConfig({
  routeRules: {
    // Generated at build time for SEO purpose
    '/': { prerender: true },
    // Cached for 1 hour
    '/api/*': { cache: { maxAge: 60 * 60 } },
    // Redirection to avoid 404
    '/old-page': {
      redirect: { to: '/new-page', statusCode: 302 }
    }
    // ...
  }
})

::read-more{to="/docs/guide/concepts/rendering#hybrid-rendering"} Learn about all available route rules are available to customize the rendering mode of your routes. ::

In addition, there are some route rules (for example, ssr, appMiddleware, and experimentalNoScripts) that are Nuxt specific to change the behavior when rendering your pages to HTML.

Some route rules (appMiddleware, redirect and prerender) also affect client-side behavior.

Nitro is used to build the app for server side rendering, as well as pre-rendering.
