`definePageMeta` is a compiler macro that you can use to set metadata for your **page** components located in the [`pages/` directory](/docs/guide/directory-structure/pages) (unless [set otherwise](/docs/api/configuration/nuxt-config#pages)). This way you can set custom metadata for each static or dynamic route of your Nuxt application.
Aliases for the record. Allows defining extra paths that will behave likea copy of the record. Allows having paths shorthands like `/users/:id` and `/u/:id`. All `alias` and `path` values must share the same params.
Set to `true` when you want to preserve page state across route changes or use the [`KeepAliveProps`](https://vuejs.org/api/built-in-components.html#keepalive) for a fine-grained control.
Define anonymous or named middleware directly within `definePageMeta`. Learn more about [route middleware](/docs/guide/directory-structure/middleware).
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.
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).
Tell Nuxt to scroll to the top before rendering the page or not. If you want to overwrite the default scroll behavior of Nuxt, you can do so in `~/app/router.options.ts` (see [docs](/docs/guide/directory-structure/pages/#router-options)) for more info.
Apart from the above properties, you can also set **custom** metadata. You may wish to do so in a type-safe way by [augmenting the type of the `meta` object](/docs/guide/directory-structure/pages/#typing-custom-metadata).
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:
You can define the layout that matches the layout's file name located (by default) in the [`layouts/` directory](/docs/guide/directory-structure/layouts). You can also disable the layout by setting the `layout` to `false`:
