--- title: How to create a static export of your Next.js application nav_title: Static Exports description: Next.js enables starting as a static site or Single-Page Application (SPA), then later optionally upgrading to use features that require a server. --- {/* The content of this doc is shared between the app and pages router. You can use the `Content` component to add content that is specific to the Pages Router. Any shared content should not be wrapped in a component. */} Next.js enables starting as a static site or Single-Page Application (SPA), then later optionally upgrading to use features that require a server. When running `next build`, Next.js generates an HTML file per route. By breaking a strict SPA into individual HTML files, Next.js can avoid loading unnecessary JavaScript code on the client-side, reducing the bundle size and enabling faster page loads. Since Next.js supports this static export, it can be deployed and hosted on any web server that can serve HTML/CSS/JS static assets. ## Configuration To enable a static export, change the output mode inside `next.config.js`: ```js filename="next.config.js" highlight={5} /** * @type {import('next').NextConfig} */ const nextConfig = { output: 'export', // Optional: Change links `/me` -> `/me/` and emit `/me.html` -> `/me/index.html` // trailingSlash: true, // Optional: Prevent automatic `/me` -> `/me/`, instead preserve `href` // skipTrailingSlashRedirect: true, // Optional: Change the output directory `out` -> `dist` // distDir: 'dist', } module.exports = nextConfig ``` After running `next build`, Next.js will create an `out` folder with the HTML/CSS/JS assets for your application. You can utilize [`getStaticProps`](/docs/pages/building-your-application/data-fetching/get-static-props) and [`getStaticPaths`](/docs/pages/building-your-application/data-fetching/get-static-paths) to generate an HTML file for each page in your `pages` directory (or more for [dynamic routes](/docs/app/api-reference/file-conventions/dynamic-routes)). ## Supported Features The core of Next.js has been designed to support static exports. ### Server Components When you run `next build` to generate a static export, Server Components consumed inside the `app` directory will run during the build, similar to traditional static-site generation. The resulting component will be rendered into static HTML for the initial page load and a static payload for client navigation between routes. No changes are required for your Server Components when using the static export, unless they consume [dynamic server functions](#unsupported-features). ```tsx filename="app/page.tsx" switcher export default async function Page() { // This fetch will run on the server during `next build` const res = await fetch('https://api.example.com/...') const data = await res.json() return
...
} ``` ### Client Components If you want to perform data fetching on the client, you can use a Client Component with [SWR](https://github.com/vercel/swr) to memoize requests. ```tsx filename="app/other/page.tsx" switcher 'use client' import useSWR from 'swr' const fetcher = (url: string) => fetch(url).then((r) => r.json()) export default function Page() { const { data, error } = useSWR( `https://jsonplaceholder.typicode.com/posts/1`, fetcher ) if (error) return 'Failed to load' if (!data) return 'Loading...' return data.title } ``` ```jsx filename="app/other/page.js" switcher 'use client' import useSWR from 'swr' const fetcher = (url) => fetch(url).then((r) => r.json()) export default function Page() { const { data, error } = useSWR( `https://jsonplaceholder.typicode.com/posts/1`, fetcher ) if (error) return 'Failed to load' if (!data) return 'Loading...' return data.title } ``` Since route transitions happen client-side, this behaves like a traditional SPA. For example, the following index route allows you to navigate to different posts on the client: ```tsx filename="app/page.tsx" switcher import Link from 'next/link' export default function Page() { return ( <>

Index Page


) } ``` ```jsx filename="app/page.js" switcher import Link from 'next/link' export default function Page() { return ( <>

Index Page

Other Page

) } ```
## Supported Features The majority of core Next.js features needed to build a static site are supported, including: - [Dynamic Routes when using `getStaticPaths`](/docs/app/api-reference/file-conventions/dynamic-routes) - Prefetching with `next/link` - Preloading JavaScript - [Dynamic Imports](/docs/pages/guides/lazy-loading) - Any styling options (e.g. CSS Modules, styled-jsx) - [Client-side data fetching](/docs/pages/building-your-application/data-fetching/client-side) - [`getStaticProps`](/docs/pages/building-your-application/data-fetching/get-static-props) - [`getStaticPaths`](/docs/pages/building-your-application/data-fetching/get-static-paths) ### Image Optimization [Image Optimization](/docs/app/api-reference/components/image) through `next/image` can be used with a static export by defining a custom image loader in `next.config.js`. For example, you can optimize images with a service like Cloudinary: ```js filename="next.config.js" /** @type {import('next').NextConfig} */ const nextConfig = { output: 'export', images: { loader: 'custom', loaderFile: './my-loader.ts', }, } module.exports = nextConfig ``` This custom loader will define how to fetch images from a remote source. For example, the following loader will construct the URL for Cloudinary: ```ts filename="my-loader.ts" switcher export default function cloudinaryLoader({ src, width, quality, }: { src: string width: number quality?: number }) { const params = ['f_auto', 'c_limit', `w_${width}`, `q_${quality || 'auto'}`] return `https://res.cloudinary.com/demo/image/upload/${params.join( ',' )}${src}` } ``` ```js filename="my-loader.js" switcher export default function cloudinaryLoader({ src, width, quality }) { const params = ['f_auto', 'c_limit', `w_${width}`, `q_${quality || 'auto'}`] return `https://res.cloudinary.com/demo/image/upload/${params.join( ',' )}${src}` } ``` You can then use `next/image` in your application, defining relative paths to the image in Cloudinary: ```tsx filename="app/page.tsx" switcher import Image from 'next/image' export default function Page() { return turtles } ``` ```jsx filename="app/page.js" switcher import Image from 'next/image' export default function Page() { return turtles } ``` ### Route Handlers Route Handlers will render a static response when running `next build`. Only the `GET` HTTP verb is supported. This can be used to generate static HTML, JSON, TXT, or other files from cached or uncached data. For example: ```ts filename="app/data.json/route.ts" switcher export async function GET() { return Response.json({ name: 'Lee' }) } ``` ```js filename="app/data.json/route.js" switcher export async function GET() { return Response.json({ name: 'Lee' }) } ``` The above file `app/data.json/route.ts` will render to a static file during `next build`, producing `data.json` containing `{ name: 'Lee' }`. If you need to read dynamic values from the incoming request, you cannot use a static export. ### Browser APIs Client Components are pre-rendered to HTML during `next build`. Because [Web APIs](https://developer.mozilla.org/docs/Web/API) like `window`, `localStorage`, and `navigator` are not available on the server, you need to safely access these APIs only when running in the browser. For example: ```jsx 'use client'; import { useEffect } from 'react'; export default function ClientComponent() { useEffect(() => { // You now have access to `window` console.log(window.innerHeight); }, []) return ...; } ``` ## Unsupported Features Features that require a Node.js server, or dynamic logic that cannot be computed during the build process, are **not** supported: - [Dynamic Routes](/docs/app/api-reference/file-conventions/dynamic-routes) with `dynamicParams: true` - [Dynamic Routes](/docs/app/api-reference/file-conventions/dynamic-routes) without `generateStaticParams()` - [Route Handlers](/docs/app/api-reference/file-conventions/route) that rely on Request - [Cookies](/docs/app/api-reference/functions/cookies) - [Rewrites](/docs/app/api-reference/config/next-config-js/rewrites) - [Redirects](/docs/app/api-reference/config/next-config-js/redirects) - [Headers](/docs/app/api-reference/config/next-config-js/headers) - [Middleware](/docs/app/api-reference/file-conventions/middleware) - [Incremental Static Regeneration](/docs/app/guides/incremental-static-regeneration) - [Image Optimization](/docs/app/api-reference/components/image) with the default `loader` - [Draft Mode](/docs/app/guides/draft-mode) - [Server Actions](/docs/app/getting-started/updating-data) - [Intercepting Routes](/docs/app/api-reference/file-conventions/intercepting-routes) Attempting to use any of these features with `next dev` will result in an error, similar to setting the [`dynamic`](/docs/app/api-reference/file-conventions/route-segment-config#dynamic) option to `error` in the root layout. ```jsx export const dynamic = 'error' ``` - [Internationalized Routing](/docs/pages/guides/internationalization) - [API Routes](/docs/pages/building-your-application/routing/api-routes) - [Rewrites](/docs/pages/api-reference/config/next-config-js/rewrites) - [Redirects](/docs/pages/api-reference/config/next-config-js/redirects) - [Headers](/docs/pages/api-reference/config/next-config-js/headers) - [Middleware](/docs/pages/api-reference/file-conventions/middleware) - [Incremental Static Regeneration](/docs/pages/guides/incremental-static-regeneration) - [Image Optimization](/docs/pages/api-reference/components/image) with the default `loader` - [Draft Mode](/docs/pages/guides/draft-mode) - [`getStaticPaths` with `fallback: true`](/docs/pages/api-reference/functions/get-static-paths#fallback-true) - [`getStaticPaths` with `fallback: 'blocking'`](/docs/pages/api-reference/functions/get-static-paths#fallback-blocking) - [`getServerSideProps`](/docs/pages/building-your-application/data-fetching/get-server-side-props) ## Deploying With a static export, Next.js can be deployed and hosted on any web server that can serve HTML/CSS/JS static assets. When running `next build`, Next.js generates the static export into the `out` folder. For example, let's say you have the following routes: - `/` - `/blog/[id]` After running `next build`, Next.js will generate the following files: - `/out/index.html` - `/out/404.html` - `/out/blog/post-1.html` - `/out/blog/post-2.html` If you are using a static host like Nginx, you can configure rewrites from incoming requests to the correct files: ```nginx filename="nginx.conf" server { listen 80; server_name acme.com; root /var/www/out; location / { try_files $uri $uri.html $uri/ =404; } # This is necessary when `trailingSlash: false`. # You can omit this when `trailingSlash: true`. location /blog/ { rewrite ^/blog/(.*)$ /blog/$1.html break; } error_page 404 /404.html; location = /404.html { internal; } } ``` ## Version History | Version | Changes | | --------- | -------------------------------------------------------------------------------------------------------------------- | | `v14.0.0` | `next export` has been removed in favor of `"output": "export"` | | `v13.4.0` | App Router (Stable) adds enhanced static export support, including using React Server Components and Route Handlers. | | `v13.3.0` | `next export` is deprecated and replaced with `"output": "export"` |
