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
Post 1
Post 2
>
)
}
```
```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
}
```
```jsx filename="app/page.js" switcher
import Image from 'next/image'
export default function Page() {
return
}
```
### 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'
```

## 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;
}
}
```
