Nuxt Configuration

Discover all the options you can use in your nuxt.config.ts file.

This file is auto-generated from Nuxt source code.

alias

You can improve your DX by defining additional aliases to access custom directories within your JavaScript and CSS.

  • Type: object
  • Default
{
  "~": "/<srcDir>",
  "@": "/<srcDir>",
  "~~": "/<rootDir>",
  "@@": "/<rootDir>",
  "assets": "/<srcDir>/assets",
  "public": "/<srcDir>/public"
}
Note: Within a webpack context (image sources, CSS - but not JavaScript) you must access your alias by prefixing it with ~.
Note: These aliases will be automatically added to the generated .nuxt/tsconfig.json so you can get full type support and path auto-complete. In case you need to extend options provided by ./.nuxt/tsconfig.json further, make sure to add them here or within the typescript.tsConfig property in nuxt.config.

Example:

export default {
  alias: {
    'images': fileURLToPath(new URL('./assets/images', import.meta.url)),
    'style': fileURLToPath(new URL('./assets/style', import.meta.url)),
    'data': fileURLToPath(new URL('./assets/other/data', import.meta.url))
  }
}

analyzeDir

The directory where Nuxt will store the generated files when running nuxt analyze.

If a relative path is specified, it will be relative to your rootDir.

  • Type: string
  • Default: "/<rootDir>/.nuxt/analyze"

app

Nuxt App configuration.

baseURL

The base path of your Nuxt application.

This can be set at runtime by setting the NUXT_APP_BASE_URL environment variable.

  • Type: string
  • Default: "/"

Example:

NUXT_APP_BASE_URL=/prefix/ node .output/server/index.mjs

buildAssetsDir

The folder name for the built site assets, relative to baseURL (or cdnURL if set). This is set at build time and should not be customized at runtime.

  • Type: string
  • Default: "/_nuxt/"

cdnURL

An absolute URL to serve the public folder from (production-only).

This can be set to a different value at runtime by setting the NUXT_APP_CDN_URL environment variable.

  • Type: string
  • Default: ""

Example:

NUXT_APP_CDN_URL=https://mycdn.org/ node .output/server/index.mjs

head

Set default configuration for <head> on every page.

  • Type: object
  • Default
{
  "meta": [
    {
      "name": "viewport",
      "content": "width=device-width, initial-scale=1"
    },
    {
      "charset": "utf-8"
    }
  ],
  "link": [],
  "style": [],
  "script": [],
  "noscript": []
}

Example:

app: {
  head: {
    meta: [
      // <meta name="viewport" content="width=device-width, initial-scale=1">
      { name: 'viewport', content: 'width=device-width, initial-scale=1' }
    ],
    script: [
      // <script src="https://myawesome-lib.js"></script>
      { src: 'https://awesome-lib.js' }
    ],
    link: [
      // <link rel="stylesheet" href="https://myawesome-lib.css">
      { rel: 'stylesheet', href: 'https://awesome-lib.css' }
    ],
    // please note that this is an area that is likely to change
    style: [
      // <style type="text/css">:root { color: red }</style>
      { children: ':root { color: red }', type: 'text/css' }
    ],
    noscript: [
      // <noscript>JavaScript is required</noscript>
      { children: 'JavaScript is required' }
    ]
  }
}

keepalive

  • Type: boolean
  • Default: false

See: https://vuejs.org/api/built-in-components.html#keepalive

layoutTransition

Default values for layout transitions.

This can be overridden with definePageMeta on an individual page. Only JSON-serializable values are allowed.

  • Type: boolean
  • Default: false

See: https://vuejs.org/api/built-in-components.html#transition

Default values for view transitions.

This only has an effect when experimental support for View Transitions is enabled in your nuxt.config file. This can be overridden with definePageMeta on an individual page.

  • Type: boolean
  • Default: false

See: https://nuxt.com/docs/getting-started/transitions#view-transitions-api-experimental

appConfig

Additional app configuration

For programmatic usage and type support, you can directly provide app config with this option. It will be merged with app.config file as default value.

nuxt

build

Shared build configuration.

analyze

Nuxt allows visualizing your bundles and how to optimize them.

Set to true to enable bundle analysis, or pass an object with options: for webpack or for vite.

  • Type: object
  • Default
{
  "template": "treemap",
  "projectRoot": "/<rootDir>",
  "filename": "/<rootDir>/.nuxt/analyze/{name}.html"
}

Example:

analyze: {
  analyzerMode: 'static'
}

templates

You can provide your own templates which will be rendered based on Nuxt configuration. This feature is specially useful for using with modules.

Templates are rendered using lodash/template.

  • Type: array

Example:

templates: [
  {
    src: '~/modules/support/plugin.js', // `src` can be absolute or relative
    dst: 'support.js', // `dst` is relative to project `.nuxt` dir
    options: {
      // Options are provided to template as `options` key
      live_chat: false
    }
  }
]

transpile

If you want to transpile specific dependencies with Babel, you can add them here. Each item in transpile can be a package name, a function, a string or regex object matching the dependency's file name.

You can also use a function to conditionally transpile. The function will receive an object ({ isDev, isServer, isClient, isModern, isLegacy }).

  • Type: array

Example:

     transpile: [({ isLegacy }) => isLegacy && 'ky']

buildDir

Define the directory where your built Nuxt files will be placed.

Many tools assume that .nuxt is a hidden directory (because it starts with a .). If that is a problem, you can use this option to prevent that.

  • Type: string
  • Default: "/<rootDir>/.nuxt"

Example:

export default {
  buildDir: 'nuxt-build'
}

builder

The builder to use for bundling the Vue part of your application.

  • Type: string
  • Default: "@nuxt/vite-builder"

components

Configure Nuxt component auto-registration.

Any components in the directories configured here can be used throughout your pages, layouts (and other components) without needing to explicitly import them.

  • Type: object
  • Default
{
  "dirs": [
    {
      "path": "~/components/global",
      "global": true
    },
    "~/components"
  ]
}

See: https://nuxt.com/docs/guide/directory-structure/components

css

You can define the CSS files/modules/libraries you want to set globally (included in every page).

Nuxt will automatically guess the file type by its extension and use the appropriate pre-processor. You will still need to install the required loader if you need to use them.

  • Type: array

Example:

css: [
  // Load a Node.js module directly (here it's a Sass file).
  'bulma',
  // CSS file in the project
  '~/assets/css/main.css',
  // SCSS file in the project
  '~/assets/css/main.scss'
]

debug

Set to true to enable debug mode.

At the moment, it prints out hook names and timings on the server, and logs hook arguments as well in the browser.

  • Type: boolean
  • Default: false

dev

Whether Nuxt is running in development mode.

Normally, you should not need to set this.

  • Type: boolean
  • Default: false

devServer

host

Dev server listening host

https

Whether to enable HTTPS.

  • Type: boolean
  • Default: false

Example:

export default defineNuxtConfig({
  devServer: {
    https: {
      key: './server.key',
      cert: './server.crt'
    }
  }
})

loadingTemplate

Template to show a loading screen

  • Type: function

port

Dev server listening port

  • Type: number
  • Default: 3000

url

Listening dev server URL.

This should not be set directly as it will always be overridden by the dev server with the full URL (for module and internal use).

  • Type: string
  • Default: "http://localhost:3000"

devServerHandlers

Nitro development-only server handlers.

  • Type: array

See: https://nitro.unjs.io/guide/routing

devtools

Enable Nuxt DevTools for development.

Breaking changes for devtools might not reflect on the version of Nuxt.

See: Nuxt DevTools for more information.

Customize default directory structure used by Nuxt.

It is better to stick with defaults unless needed.

assets

The assets directory (aliased as ~assets in your build).

  • Type: string
  • Default: "assets"

layouts

The layouts directory, each file of which will be auto-registered as a Nuxt layout.

  • Type: boolean
  • Default: false

See: CookieStore

crossOriginPrefetch

Enable cross-origin prefetch using the Speculation Rules API.

  • Type: boolean
  • Default: false

defaults

This allows specifying the default options for core Nuxt components and composables.

These options will likely be moved elsewhere in the future, such as into app.config or into the app/ directory.

nuxtLink

componentName
  • Type: string
  • Default: "NuxtLink"

useAsyncData

Options that apply to useAsyncData (and also therefore useFetch)

deep
  • Type: boolean
  • Default: true

useFetch

emitRouteChunkError

Emit app:chunkError hook when there is an error loading vite/webpack chunks.

By default, Nuxt will also perform a hard reload of the new route when a chunk fails to load when navigating to a new route. You can disable automatic handling by setting this to false, or handle chunk errors manually by setting it to manual.

  • Type: string
  • Default: "automatic"

See: Nuxt PR #19038

externalVue

Externalize vue, @vue/* and vue-router when building.

  • Type: boolean
  • Default: true

See: Nuxt Issue #13632

headNext

Use new experimental head optimisations: - Add the capo.js head plugin in order to render tags in of the head in a more performant way. - Uses the hash hydration plugin to reduce initial hydration

  • Type: boolean
  • Default: false

See: [Nuxt Discussion #22632](https://github.com/nuxt/nuxt/discussions/22632]

inlineRouteRules

Allow defining routeRules directly within your ~/pages directory using defineRouteRules.

Rules are converted (based on the path) and applied for server requests. For example, a rule defined in ~/pages/foo/bar.vue will be applied to /foo/bar requests. A rule in ~/pages/foo/[id].vue will be applied to /foo/** requests. For more control, such as if you are using a custom path or alias set in the page's definePageMeta, you should set routeRules directly within your nuxt.config.

  • Type: boolean
  • Default: false

localLayerAliases

Resolve ~, ~~, @ and @@ aliases located within layers with respect to their layer source and root directories.

  • Type: boolean
  • Default: true

noVueServer

Disable vue server renderer endpoint within nitro.

  • Type: boolean
  • Default: false

payloadExtraction

When this option is enabled (by default) payload of pages that are prerendered are extracted

  • Type: boolean
  • Default: true

polyfillVueUseHead

Whether or not to add a compatibility layer for modules, plugins or user code relying on the old @vueuse/head API.

This can be disabled for most Nuxt sites to reduce the client-side bundle by ~0.5kb.

  • Type: boolean
  • Default: false

renderJsonPayloads

Render JSON payloads with support for revivifying complex types.

  • Type: boolean
  • Default: true

respectNoSSRHeader

Allow disabling Nuxt SSR responses by setting the x-nuxt-no-ssr header.

  • Type: boolean
  • Default: false

restoreState

Whether to restore Nuxt app state from sessionStorage when reloading the page after a chunk error or manual reloadNuxtApp() call.

To avoid hydration errors, it will be applied only after the Vue app has been mounted, meaning there may be a flicker on initial load. Consider carefully before enabling this as it can cause unexpected behavior, and consider providing explicit keys to useState as auto-generated keys may not match across builds.

  • Type: boolean
  • Default: false

scanPageMeta

Allow exposing some route metadata defined in definePageMeta at build-time to modules (alias, name, path, redirect).

This only works with static or strings/arrays rather than variables or conditional assignment. https://github.com/nuxt/nuxt/issues/24770

  • Type: boolean
  • Default: false

sharedPrerenderData

Automatically share payload data between pages that are prerendered. This can result in a significant performance improvement when prerendering sites that use useAsyncData or useFetch and fetch the same data in different pages.

It is particularly important when enabling this feature to make sure that any unique key of your data is always resolvable to the same data. For example, if you are using useAsyncData to fetch data related to a particular page, you should provide a key that uniquely matches that data. (useFetch should do this automatically for you.)

  • Type: boolean
  • Default: false

Example:

// This would be unsafe in a dynamic page (e.g. `[slug].vue`) because the route slug makes a difference
// to the data fetched, but Nuxt can't know that because it's not reflected in the key.
const route = useRoute()
const { data } = await useAsyncData(async () => {
  return await $fetch(`/api/my-page/${route.params.slug}`)
})
// Instead, you should use a key that uniquely identifies the data fetched.
const { data } = await useAsyncData(route.params.slug, async () => {
  return await $fetch(`/api/my-page/${route.params.slug}`)
})

templateRouteInjection

By default the route object returned by the auto-imported useRoute() composable is kept in sync with the current page in view in <NuxtPage>. This is not true for vue-router's exported useRoute or for the default $route object available in your Vue templates.

By enabling this option a mixin will be injected to keep the $route template object in sync with Nuxt's managed useRoute().

  • Type: boolean
  • Default: true

treeshakeClientOnly

Tree shakes contents of client-only components from server bundle.

  • Type: boolean
  • Default: true

See: Nuxt PR #5750

typedPages

Enable the new experimental typed router using unplugin-vue-router.

  • Type: boolean
  • Default: false

viewTransition

Enable View Transition API integration with client-side router.

  • Type: boolean
  • Default: false

See: View Transitions API

watcher

Set an alternative watcher that will be used as the watching service for Nuxt.

Nuxt uses 'chokidar-granular' by default, which will ignore top-level directories (like node_modules and .git) that are excluded from watching. You can set this instead to parcel to use @parcel/watcher, which may improve performance in large projects or on Windows platforms. You can also set this to chokidar to watch all files in your source directory.

  • Type: string
  • Default: "chokidar-granular"

See: chokidarSee: Parcel watcher

writeEarlyHints

Write early hints when using node server.

  • Type: boolean
  • Default: false
Note: nginx does not support 103 Early hints in the current version.

extends

Extend project from multiple local or remote sources.

Value should be either a string or array of strings pointing to source directories or config path relative to current config. You can use github:, gh: gitlab: or bitbucket:.

  • Default: null

See: https://github.com/unjs/c12#extending-config-layer-from-remote-sourcesSee: https://github.com/unjs/giget

extensions

The extensions that should be resolved by the Nuxt resolver.

  • Type: array
  • Default
[
  ".js",
  ".jsx",
  ".mjs",
  ".ts",
  ".tsx",
  ".vue"
]

features

Some features of Nuxt are available on an opt-in basis, or can be disabled based on your needs.

inlineStyles

Inline styles when rendering HTML (currently vite only).

You can also pass a function that receives the path of a Vue component and returns a boolean indicating whether to inline the styles for that component.

  • Type: boolean
  • Default: true

noScripts

Turn off rendering of Nuxt scripts and JS resource hints. You can also disable scripts more granularly within routeRules.

  • Type: boolean
  • Default: false

future

future is for early opting-in to new features that will become default in a future (possibly major) version of the framework.

typescriptBundlerResolution

This enables 'Bundler' module resolution mode for TypeScript, which is the recommended setting for frameworks like Nuxt and Vite.

It improves type support when using modern libraries with exports. You can set it to false to use the legacy 'Node' mode, which is the default for TypeScript. See https://github.com/microsoft/TypeScript/pull/51669

  • Type: boolean
  • Default: true

generate

exclude

This option is no longer used. Instead, use nitro.prerender.ignore.

  • Type: array

routes

The routes to generate.

If you are using the crawler, this will be only the starting point for route generation. This is often necessary when using dynamic routes. It is preferred to use nitro.prerender.routes.

  • Type: array

Example:

routes: ['/users/1', '/users/2', '/users/3']

hooks

Hooks are listeners to Nuxt events that are typically used in modules, but are also available in nuxt.config.

Internally, hooks follow a naming pattern using colons (e.g., build:done). For ease of configuration, you can also structure them as an hierarchical object in nuxt.config (as below).

  • Default: null

Example:

import fs from 'node:fs'
import path from 'node:path'
export default {
  hooks: {
    build: {
      done(builder) {
        const extraFilePath = path.join(
          builder.nuxt.options.buildDir,
          'extra-file'
        )
        fs.writeFileSync(extraFilePath, 'Something extra')
      }
    }
  }
}

ignore

More customizable than ignorePrefix: all files matching glob patterns specified inside the ignore array will be ignored in building.

  • Type: array
  • Default
[
  "**/*.stories.{js,cts,mts,ts,jsx,tsx}",
  "**/*.{spec,test}.{js,cts,mts,ts,jsx,tsx}",
  "**/*.d.{cts,mts,ts}",
  "**/.{pnpm-store,vercel,netlify,output,git,cache,data}",
  ".nuxt/analyze",
  ".nuxt",
  "**/-*.*"
]

ignoreOptions

Pass options directly to node-ignore (which is used by Nuxt to ignore files).

See: node-ignoreExample:

ignoreOptions: {
  ignorecase: false
}

ignorePrefix

Any file in pages/, layouts/, middleware/ or store/ will be ignored during building if its filename starts with the prefix specified by ignorePrefix.

  • Type: string
  • Default: "-"

imports

Configure how Nuxt auto-imports composables into your application.

See: Nuxt 3 documentation

dirs

An array of custom directories that will be auto-imported. Note that this option will not override the default directories (~/composables, ~/utils).

  • Type: array

Example:

imports: {
  // Auto-import pinia stores defined in `~/stores`
  dirs: ['stores']
}

global

  • Type: boolean
  • Default: false

logLevel

Log level when building logs.

Defaults to 'silent' when running in CI or when a TTY is not available. This option is then used as 'silent' in Vite and 'none' in Webpack

  • Type: string
  • Default: "info"

modules

Modules are Nuxt extensions which can extend its core functionality and add endless integrations.

Each module is either a string (which can refer to a package, or be a path to a file), a tuple with the module as first string and the options as a second object, or an inline module function. Nuxt tries to resolve each item in the modules array using node require path (in node_modules) and then will be resolved from project srcDir if ~ alias is used.

  • Type: array
Note: Modules are executed sequentially so the order is important.

Example:

modules: [
  // Using package name
  '@nuxtjs/axios',
  // Relative to your project srcDir
  '~/modules/awesome.js',
  // Providing options
  ['@nuxtjs/google-analytics', { ua: 'X1234567' }],
  // Inline definition
  function () {}
]

modulesDir

Used to set the modules directories for path resolving (for example, webpack's resolveLoading, nodeExternals and postcss).

The configuration path is relative to options.rootDir (default is current working directory). Setting this field may be necessary if your project is organized as a yarn workspace-styled mono-repository.

  • Type: array
  • Default
[
  "/<rootDir>/node_modules"
]

Example:

export default {
  modulesDir: ['../../node_modules']
}

nitro

Configuration for Nitro.

See: https://nitro.unjs.io/config/

routeRules

  • Type: object

optimization

Build time optimization configuration.

asyncTransforms

Options passed directly to the transformer from unctx that preserves async context after await.

asyncFunctions

  • Type: array

defineNuxtPlugin
  • Type: array
  • Default
[
  "setup"
]
definePageMeta
  • Type: array
  • Default
[
  "middleware",
  "validate"
]

keyedComposables

Functions to inject a key for.

As long as the number of arguments passed to the function is less than argumentLength, an additional magic string will be injected that can be used to deduplicate requests between server and client. You will need to take steps to handle this additional key. The key will be unique based on the location of the function being invoked within the file.

  • Type: array
  • Default
[
  {
    "name": "useId",
    "argumentLength": 1
  },
  {
    "name": "callOnce",
    "argumentLength": 2
  },
  {
    "name": "defineNuxtComponent",
    "argumentLength": 2
  },
  {
    "name": "useState",
    "argumentLength": 2
  },
  {
    "name": "useFetch",
    "argumentLength": 3
  },
  {
    "name": "useAsyncData",
    "argumentLength": 3
  },
  {

    "onServerPrefetch",
    "onRenderTracked",
    "onRenderTriggered"
  ],
  "#app": [
    "definePayloadReducer",
    "definePageMeta"
  ]

    "onRenderTriggered",
    "onActivated",
    "onDeactivated",
    "onBeforeUnmount"
  ],
  "#app": [
    "definePayloadReviver",
    "definePageMeta"
  ]
}

pages

Whether to use the vue-router integration in Nuxt 3. If you do not provide a value it will be enabled if you have a pages/ directory in your source folder.

  • Type: boolean

plugins

An array of nuxt app plugins.

Each plugin can be a string (which can be an absolute or relative path to a file). If it ends with .client or .server then it will be automatically loaded only in the appropriate context. It can also be an object with src and mode keys.

  • Type: array
Note: Plugins are also auto-registered from the ~/plugins directory and these plugins do not need to be listed in nuxt.config unless you need to customize their order. All plugins are deduplicated by their src path.

See: https://nuxt.com/docs/guide/directory-structure/pluginsExample:

plugins: [
  '~/plugins/foo.client.js', // only in client side
  '~/plugins/bar.server.js', // only in server side
  '~/plugins/baz.js', // both client & server
  { src: '~/plugins/both-sides.js' },
  { src: '~/plugins/client-only.js', mode: 'client' }, // only on client side
  { src: '~/plugins/server-only.js', mode: 'server' } // only on server side
]

Options for configuring PostCSS plugins.

https://postcss.org/

autoprefixer

https://github.com/postcss/autoprefixer

cssnano

https://cssnano.co/docs/config-file/#configuration-options

  • Type: object

rootDir

Define the root directory of your application.

This property can be overwritten (for example, running nuxt ./my-app/ will set the rootDir to the absolute path of ./my-app/ from the current/working directory. It is normally not needed to configure this option.

  • Type: string
  • Default: "/<rootDir>"

routeRules

Global route options applied to matching server routes.

Experimental: This is an experimental feature and API may change in the future. See: https://nitro.unjs.io/config/#routerules

router

options

Additional router options passed to vue-router. On top of the options for vue-router, Nuxt offers additional options to customize the router (see below).

Note: Only JSON serializable options should be passed by Nuxt config. For more control, you can use app/router.options.ts file.

See: documentation.

hashMode

You can enable hash history in SPA mode. In this mode, router uses a hash character (#) before the actual URL that is internally passed. When enabled, the URL is never sent to the server and SSR is not supported.

  • Type: boolean
  • Default: false

Default: false

scrollBehaviorType

Customize the scroll behavior for hash links.

  • Type: string
  • Default: "auto"

Default: 'auto'

runtimeConfig

Runtime config allows passing dynamic config and environment variables to the Nuxt app context.

The value of this object is accessible from server only using useRuntimeConfig. It mainly should hold private configuration which is not exposed on the frontend. This could include a reference to your API secret tokens. Anything under public and app will be exposed to the frontend as well. Values are automatically replaced by matching env variables at runtime, e.g. setting an environment variable NUXT_API_KEY=my-api-key NUXT_PUBLIC_BASE_URL=/foo/ would overwrite the two values in the example below.

  • Type: object
  • Default
{
  "public": {},
  "app": {
    "baseURL": "/",
    "buildAssetsDir": "/_nuxt/",
    "cdnURL": ""
  }
}

Example:

export default {
 runtimeConfig: {
    apiKey: '' // Default to an empty string, automatically set at runtime using process.env.NUXT_API_KEY
    public: {
       baseURL: '' // Exposed to the frontend as well.
    }
  }
}

serverDir

Define the server directory of your Nuxt application, where Nitro routes, middleware and plugins are kept.

If a relative path is specified, it will be relative to your rootDir.

  • Type: string
  • Default: "/<srcDir>/server"

serverHandlers

Nitro server handlers.

Each handler accepts the following options: - handler: The path to the file defining the handler. - route: The route under which the handler is available. This follows the conventions of https://github.com/unjs/radix3. - method: The HTTP method of requests that should be handled. - middleware: Specifies whether it is a middleware handler. - lazy: Specifies whether to use lazy loading to import the handler.

  • Type: array

See: https://nuxt.com/docs/guide/directory-structure/server

Note: Files from server/api, server/middleware and server/routes will be automatically registered by Nuxt.

Example:

serverHandlers: [
  { route: '/path/foo/**:name', handler: '~/server/foohandler.ts' }
]

sourcemap

Whether to generate sourcemaps.

  • Type: object
  • Default
{
  "server": true,
  "client": false
}

spaLoadingTemplate

Boolean or a path to an HTML file with the contents of which will be inserted into any HTML page rendered with ssr: false. - If it is unset, it will use ~/app/spa-loading-template.html file in one of your layers, if it exists. - If it is false, no SPA loading indicator will be loaded. - If true, Nuxt will look for ~/app/spa-loading-template.html file in one of your layers, or a

default Nuxt image will be used. Some good sources for spinners are SpinKit or SVG Spinners.

  • Default: null

Example: ~/app/spa-loading-template.html

  }
  100% {
    transform: translate(-50%, -50%) rotate(360deg);
  }
}
</style>

}

This would work with the following folder structure:

-| app/
---| node_modules/
---| nuxt.config.js
---| package.json
---| src/
------| assets/
------| components/

The 'shared' option is advised for module authors, who will want to support multiple possible builders.

  • Default: null

includeWorkspace

Include parent workspace in the Nuxt project. Mostly useful for themes and module authors.

  • Type: boolean
