# Meta Tags
If you need to access the component state with `head`, you should migrate to using [`useHead`](/docs/api/composables/use-head) .
If you need to use the Options API, there is a `head()` method you can use when you use `defineNuxtComponent`.
## Migration
### Set `bridge.meta`
```js
import { defineNuxtConfig } from '@nuxt/bridge'
export default defineNuxtConfig({
bridge: {
meta: true,
nitro: false // If migration to Nitro is complete, set to true
}
})
```
### Update head properties
In your `nuxt.config`, rename `head` to `meta`. (Note that objects no longer have a `hid` key for deduplication.)
::code-group
```ts [Nuxt 2]
export default {
head: {
titleTemplate: '%s - Nuxt',
meta: [
{ charset: 'utf-8' },
{ name: 'viewport', content: 'width=device-width, initial-scale=1' },
{ hid: 'description', name: 'description', content: 'Meta description' }
]
}
}
```
```ts [Nuxt 3]
export default defineNuxtConfig({
app: {
head: {
titleTemplate: '%s - Nuxt',
meta: [
{ charset: 'utf-8' },
{ name: 'viewport', content: 'width=device-width, initial-scale=1' },
{ name: 'description', content: 'Meta description' }
]
}
}
})
```

## `useHead` Composables
Nuxt Bridge provides a new Nuxt 3 meta API that can be accessed with a new [`useHead`](/docs/api/composables/use-head) composable.
```vue
```
::alert
This [`useHead`](/docs/api/composables/use-head) composable uses `@unhead/vue` under the hood (rather than `vue-meta`) to manipulate your ``.
::
::alert{type=warning}
We recommend not using the native Nuxt 2 `head()` properties in addition to [`useHead`](/docs/api/composables/use-head) , as they may conflict.
::
For more information on how to use this composable, see [the docs](/docs/getting-started/seo-meta).
## Options API
```vue
```
## Title Template
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 `/layouts` directory.
```vue [layouts/default.vue]
```
