Experimental Features
The Nuxt experimental features can be enabled in the Nuxt configuration file.
Internally, Nuxt uses @nuxt/schema
to define these experimental features. You can refer to the API documentation or the source code for more information.
Note that these features are experimental and could be removed or modified in the future.
asyncContext
Enable native async context to be accessible for nested composables in Nuxt and in Nitro. See full explanation in #20918.
export defineNuxtConfig({ experimental: { asyncContext: true } })
asyncEntry
Enables generation of an async entry point for the Vue bundle, aiding module federation support.
export defineNuxtConfig({ experimental: { asyncEntry: true } })
reactivityTransform
Enables Vue's reactivity transform. Note that this feature has been marked as deprecated in Vue 3.3 and is planned to be removed from core in Vue 3.4.
export defineNuxtConfig({ experimental: { reactivityTransform: true } })
externalVue
Externalizes vue
, @vue/*
and vue-router
when building.
Enabled by default.
export defineNuxtConfig({ experimental: { externalVue: true } })
This feature will likely be removed in Nuxt 3.6.
treeshakeClientOnly
Tree shakes contents of client-only components from server bundle. Enabled by default.
export defineNuxtConfig({ experimental: { treeshakeClientOnly: true } })
emitRouteChunkError
Emits app:chunkError
hook when there is an error loading vite/webpack chunks. Default behavior is to perform a hard reload of the new route when a chunk fails to load.
You can disable automatic handling by setting this to false
, or handle chunk errors manually by setting it to manual
.
export defineNuxtConfig({ experimental: { emitRouteChunkError: 'automatic' } }) // or 'manual' or false
restoreState
Allows Nuxt app state to be restored 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.
export defineNuxtConfig({ experimental: { restoreState: true } })
inlineSSRStyles
Inlines styles when rendering HTML. This is currently available only when using Vite. 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.
export defineNuxtConfig({ experimental: { inlineSSRStyles: true } }) // or a function to determine inlining
noScripts
Disables rendering of Nuxt scripts and JS resource hints. Can also be configured granularly within routeRules
.
export defineNuxtConfig({ experimental: { noScripts: true } })
renderJsonPayloads
Allows rendering of JSON payloads with support for revivifying complex types. Enabled by default.
export defineNuxtConfig({ experimental: { renderJsonPayloads: true } })
noVueServer
Disables Vue server renderer endpoint within Nitro.
export defineNuxtConfig({ experimental: { noVueServer: true } })
payloadExtraction
Enables extraction of payloads of pages generated with nuxt generate
.
export defineNuxtConfig({ experimental: { payloadExtraction: true } })
clientFallback
Enables the experimental <NuxtClientFallback>
component for rendering content on the client if there's an error in SSR.
export defineNuxtConfig({ experimental: { clientFallback: true } })
crossOriginPrefetch
Enables cross-origin prefetch using the Speculation Rules API.
export defineNuxtConfig({ experimental: { crossOriginPrefetch: true } })
viewTransition
Enables View Transition API integration with client-side router.
export defineNuxtConfig({ experimental: { viewTransition: true } })
writeEarlyHints
Enables writing of early hints when using node server.
export defineNuxtConfig({ experimental: { writeEarlyHints: true } })
componentIslands
Enables experimental component islands support with <NuxtIsland>
and .island.vue
files.
export defineNuxtConfig({ experimental: { componentIslands: true } })
You can follow the server components roadmap on GitHub.
configSchema
Enables config schema support. Enabled by default.
export defineNuxtConfig({ experimental: { configSchema: true } })
polyfillVueUseHead
Adds a compatibility layer for modules, plugins, or user code relying on the old @vueuse/head
API.
export defineNuxtConfig({ experimental: { polyfillVueUseHead: false } })
respectNoSSRHeader
Allow disabling Nuxt SSR responses by setting the x-nuxt-no-ssr
header.
export defineNuxtConfig({ experimental: { respectNoSSRHeader: false } })
localLayerAliases
Resolve ~
, ~~
, @
and @@
aliases located within layers with respect to their layer source and root directories.
Enabled by default.
export defineNuxtConfig({ experimental: { localLayerAliases: true } })
typedPages
Enable the new experimental typed router using unplugin-vue-router.
export defineNuxtConfig({ experimental: { typedPages: false } })
Out of the box, this will enable typed usage of navigateTo
, <NuxtLink>
, router.push()
and more.
You can even get typed params within a page by using const route = useRoute('route-name')
.
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.
export defineNuxtConfig({
experimental: {
watcher: 'chokidar-granular' // 'chokidar' or 'parcel' are also options
}
})
