## Defaults

Out-of-the-box, Nuxt provides sane defaults, which you can override if needed.

```ts twoslash [nuxt.config.ts]
export default defineNuxtConfig({
  app: {
    head: {
      charset: 'utf-8',
      viewport: 'width=device-width, initial-scale=1',
    }
  }
})
```

Providing an [`app.head`](/docs/api/nuxt-config#head) property in your [`nuxt.config.ts`](/docs/guide/directory-structure/nuxt-config) allows you to customize the head for your entire app.

::callout
This method does not allow you to provide reactive data. We recommend to use `useHead()` in `app.vue`.
::

Shortcuts are available to make configuration easier: `charset` and `viewport`. You can also provide any of the keys listed below in [Types](#types).

## `useHead`

The [`useHead`](/docs/api/composables/use-head) composable function allows you to manage your head tags programmatically and reactively,
powered by [Unhead](https://unhead.unjs.io).

As with all composables, it can only be used with a components `setup` and lifecycle hooks.

```vue twoslash [app.vue]
<script setup lang="ts">
useHead({
  title: 'My App',
  meta: [
    { name: 'description', content: 'My amazing site.' }
  ],
  bodyAttrs: {
    class: 'test'
  },
  script: [ { innerHTML: 'console.log(\'Hello world\')' } ]
})
</script>
```

We recommend to take a look at the [`useHead`](/docs/api/composables/use-head) and [`useHeadSafe`](/docs/api/composables/use-head-safe) composables.

## `useSeoMeta`

The [`useSeoMeta`](/docs/api/composables/use-seo-meta) composable lets you define your site's SEO meta tags as a flat object with full TypeScript support.

This helps you avoid typos and common mistakes, such as using `name` instead of `property`.

```vue twoslash [app.vue]
<script setup lang="ts">
useSeoMeta({
  title: 'My Amazing Site',
  ogTitle: 'My Amazing Site',
  description: 'This is my amazing site, let me tell you all about it.',
  ogDescription: 'This is my amazing site, let me tell you all about it.',
  ogImage: 'https://example.com/image.png',
  twitterCard: 'summary_large_image',
})
</script>
```

## Components

Nuxt provides `<Title>`, `<Base>`, `<NoScript>`, `<Style>`, `<Meta>`, `<Link>`, `<Body>`, `<Html>` and `<Head>` components so that you can interact directly with your metadata within your component's template.

Because these component names match native HTML elements, they must be capitalized in the template.

`<Head>` and `<Body>` can accept nested meta tags (for aesthetic reasons) but this does not affect _where_ the nested meta tags are rendered in the final HTML.

<!-- @case-police-ignore html -->

```vue [app.vue]
<script setup lang="ts">
const title = ref('Hello World')
</script>

<template>
  <div>
    <Head>
      <Title>{{ title }}</Title>
      <Meta name="description" :content="title" />
      <Style type="text/css" children="body { background-color: green; }" ></Style>
    </Head>

    <h1>{{ title }}</h1>
  </div>
</template>
```

## Types

Below are the non-reactive types used for [`useHead`](/docs/api/composables/use-head), [`app.head`](/docs/api/nuxt-config#head) and components.

```ts
interface MetaObject {
  title?: string
  titleTemplate?: string | ((title?: string) => string)
  templateParams?: Record<string, string | Record<string, string>>
  base?: Base
  link?: Link[]
  meta?: Meta[]
  style?: Style[]
  script?: Script[]
  noscript?: Noscript[];
  htmlAttrs?: HtmlAttributes;
  bodyAttrs?: BodyAttributes;
}
```

See [@unhead/schema](https://github.com/unjs/unhead/blob/main/packages/schema/src/schema.ts) for more detailed types.

## Features

### Reactivity

Reactivity is supported on all properties, by providing a computed value, a getter, or a reactive object.

It's recommended to use getters (`() => value`) over computed (`computed(() => value)`).

::code-group

  ```vue twoslash [useHead]
  <script setup lang="ts">
  const description = ref('My amazing site.')

  useHead({
    meta: [
      { name: 'description', content: description }
    ],
  })
  </script>
  ```
  
  ```vue twoslash [useSeoMeta]
  <script setup lang="ts">
  const description = ref('My amazing site.')

  useSeoMeta({
    description
  })
  </script>
  ```

  ```vue [Components]
  <script setup lang="ts">
  const description = ref('My amazing site.')
  </script>
  
  <template>
    <div>
      <Meta name="description" :content="description" />
    </div>
  </template>
  ```

::

### Title Template

You can use the `titleTemplate` option to provide a dynamic template for customizing the title of your site. For example, you could add the name of your site to the title of every page.

The `titleTemplate` can either be a string, where `%s` is replaced with the title, or a function.

If you want to use a function (for full control), then this cannot be set in your `nuxt.config`, and it is recommended instead to set it within your `app.vue` file, where it will apply to all pages on your site:

::code-group

  ```vue twoslash [useHead]
  <script setup lang="ts">
  useHead({
    titleTemplate: (titleChunk) => {
      return titleChunk ? `${titleChunk} - Site Title` : 'Site Title';
    }
  })
  </script>
  ```

::

Now, if you set the title to `My Page` with [`useHead`](/docs/api/composables/use-head) on another page of your site, the title would appear as 'My Page - Site Title' in the browser tab. You could also pass `null` to default to 'Site Title'.

### Body Tags

You can use the `tagPosition: 'bodyClose'` option on applicable tags to append them to the end of the `<body>` tag.

For example:

```vue twoslash
<script setup lang="ts">
useHead({
  script: [
    {
      src: 'https://third-party-script.com',
      // valid options are: 'head' | 'bodyClose' | 'bodyOpen'
      tagPosition: 'bodyClose'
    }
  ]
})
</script>
```

## Examples

### With `definePageMeta`

Within your [`pages/` directory](/docs/guide/directory-structure/pages), you can use `definePageMeta` along with [`useHead`](/docs/api/composables/use-head) to set metadata based on the current route.

For example, you can first set the current page title (this is extracted at build time via a macro, so it can't be set dynamically):

```vue twoslash [pages/some-page.vue]
<script setup lang="ts">
definePageMeta({
  title: 'Some Page'
})
</script>
```

And then in your layout file, you might use the route's metadata you have previously set:

```vue twoslash [layouts/default.vue]
<script setup lang="ts">
const route = useRoute()

useHead({
  meta: [{ property: 'og:title', content: `App Name - ${route.meta.title}` }]
})
</script>
```

:link-example{to="/docs/examples/features/meta-tags"}

:read-more{to="/docs/guide/directory-structure/pages/#page-metadata"}

### Dynamic Title

In the example below, `titleTemplate` is set either as a string with the `%s` placeholder or as a `function`, which allows greater flexibility in setting the page title dynamically for each route of your Nuxt app:

```vue twoslash [app.vue]
<script setup lang="ts">
useHead({
  // as a string,
  // where `%s` is replaced with the title
  titleTemplate: '%s - Site Title',
})
</script>
```

```vue twoslash [app.vue]
<script setup lang="ts">
useHead({
  // or as a function
  titleTemplate: (productCategory) => {
    return productCategory
      ? `${productCategory} - Site Title`
      : 'Site Title'
  }
})
</script>
```

`nuxt.config` is also used as an alternative way of setting the page title. However, `nuxt.config` does not allow the page title to be dynamic. Therefore, it is recommended to use `titleTemplate` in the `app.vue` file to add a dynamic title, which is then applied to all routes of your Nuxt app.

### External CSS

The example below shows how you might enable Google Fonts using either the `link` property of the [`useHead`](/docs/api/composables/use-head) composable or using the `<Link>` component:

::code-group

  ```vue twoslash [useHead]
  <script setup lang="ts">
  useHead({
    link: [
      {
        rel: 'preconnect',
        href: 'https://fonts.googleapis.com'
      },
      {
        rel: 'stylesheet',
        href: 'https://fonts.googleapis.com/css2?family=Roboto&display=swap',
        crossorigin: ''
      }
    ]
  })
  </script>
  ```

  ```vue [Components]
  <template>
    <div>
      <Link rel="preconnect" href="https://fonts.googleapis.com" />
      <Link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Roboto&display=swap" crossorigin="" />
    </div>
  </template>
  ```
