| Meta Tags | Learn how to migrate from Nuxt 2 to Nuxt Bridge new meta tags. |
If you need to access the component state with head, you should migrate to using useHead .
If you need to use the Options API, there is a head() method you can use when you use defineNuxtComponent.
Migration
Set bridge.meta
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
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' }
]
}
}
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 composable.
<script setup lang="ts">
useHead({
title: 'My Nuxt App',
})
</script>
::callout
This useHead composable uses @unhead/vue under the hood (rather than vue-meta) to manipulate your <head>.
::
::callout{color="amber" icon="i-ph-warning-duotone"}
We recommend not using the native Nuxt 2 head() properties in addition to useHead , as they may conflict.
::
For more information on how to use this composable, see the docs.
Options API
<script>
// if using options API `head` method you must use `defineNuxtComponent`
export default defineNuxtComponent({
head (nuxtApp) {
// `head` receives the nuxt app but cannot access the component instance
return {
meta: [{
name: 'description',
content: 'This is my page description.'
}]
}
}
})
</script>
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.
<script setup lang="ts">
useHead({
titleTemplate: (titleChunk) => {
return titleChunk ? `${titleChunk} - Site Title` : 'Site Title';
}
})
</script>
