definePageMeta is a compiler macro that you can use to set metadata for your page components located in the pages/ directory (unless set otherwise). This way you can set custom metadata for each static or dynamic route of your Nuxt application.

<script setup>  definePageMeta({    layout: 'default'  })</script>


definePageMeta(meta: PageMeta) => voidinterface PageMeta {  validate?: (route: RouteLocationNormalized) => boolean | Promise<boolean> | Partial<NuxtError> | Promise<Partial<NuxtError>>  redirect?: RouteRecordRedirectOption  alias?: string | string[]  pageTransition?: boolean | TransitionProps  layoutTransition?: boolean | TransitionProps  key?: false | string | ((route: RouteLocationNormalizedLoaded) => string)  keepalive?: boolean | KeepAliveProps  layout?: false | LayoutKey | Ref<LayoutKey> | ComputedRef<LayoutKey>  middleware?: MiddlewareKey | NavigationGuard | Array<MiddlewareKey | NavigationGuard>  [key: string]: any}



  • Type: PageMeta
    An object accepting the following page metadata:
    • Type: string | string[]
      Aliases for the record. Allows defining extra paths that will behave like a copy of the record. Allows having paths shorthands like /users/:id and /u/:id. All alias and path values must share the same params.

    • Type: boolean | KeepAliveProps
      Set to true when you want to preserve page state across route changes or use the KeepAliveProps for a fine-grained control.

    • Type: false | string | ((route: RouteLocationNormalizedLoaded) => string)
      Set key value when you need more control over when the <NuxtPage> component is re-rendered.

    • Type: false | LayoutKey | Ref<LayoutKey> | ComputedRef<LayoutKey>
      Set a static or dynamic name of the layout for each route. This can be set to false in case the default layout needs to be disabled.

    • Type: boolean | TransitionProps
      Set name of the transition to apply for current layout. You can also set this value to false to disable the layout transition.

    • Type: MiddlewareKey | NavigationGuard | Array<MiddlewareKey | NavigationGuard>
      Define anonymous or named middleware directly within definePageMeta. Learn more about route middleware.

    • Type: boolean | TransitionProps
      Set name of the transition to apply for current page. You can also set this value to false to disable the page transition.

    • Type: RouteRecordRedirectOption
      Where to redirect if the route is directly matched. The redirection happens before any navigation guard and triggers a new navigation with the new target location.

    • Type: (route: RouteLocationNormalized) => boolean | Promise<boolean> | Partial<NuxtError> | Promise<Partial<NuxtError>>
      Validate whether a given route can validly be rendered with this page. Return true if it is valid, or false if not. If another match can't be found, this will mean a 404. You can also directly return an object with statusCode/statusMessage to respond immediately with an error (other matches will not be checked).

    [key: string]


Basic Usage

The example below demonstrates:

  • how key can be a function that returns a value;
  • how keepalive property makes sure that the <modal> component is not cached when switching between multiple components;
  • adding pageType as a custom property:
<script setup>  definePageMeta({    key: (route) => route.fullPath,    keepalive: {      exclude: ['modal']    },    pageType: 'Checkout'  })</script>

Defining Middleware

The example below shows how the middleware can be defined using a function directly within the definePageMeta or set as a string that matches the middleware file name located in the middleware/ directory:

<script setup>  definePageMeta({    // define middleware as a function    middleware: [      function (to, from) {        const auth = useState('auth')        if (!auth.value.authenticated) {            return navigateTo('/login')        }        return navigateTo('/checkout')      }    ],    // ... or a string    middleware: 'auth'    // ... or multiple strings    middleware: ['auth', 'another-named-middleware']})</script>

Defining Layout

You can define the layout that matches the layout's file name located (by default) in the layouts/ directory. You can also disable the layout by setting the layout to false:

<script setup>  definePageMeta({    // set custom layout    layout: 'admin'    // ... or disable a default layout    layout: false  })</script>
