npm i @vueuse/head
# Or Yarn
yarn add @vueuse/head
Requires vue >= v3 or >=2.7
Register the Vue plugin:
import { createApp } from "vue"
import { createHead } from "@vueuse/head"
const app = createApp()
const head = createHead()
app.use(head)
app.mount("#app")
Manage head with the composition API useHead in your component:
<script>
import { defineComponent, computed, reactive } from "vue"
import { useHead } from "@vueuse/head"
export default defineComponent({
setup() {
const siteData = reactive({
title: `My website`,
description: `My beautiful website`,
})
useHead({
// Can be static or computed
title: computed(() => siteData.title),
meta: [
{
name: `description`,
content: computed(() => siteData.description),
},
],
})
},
})
</script>
import { renderToString } from "@vue/server-renderer"
import { renderHeadToString } from "@vueuse/head"
const appHTML = await renderToString(yourVueApp)
// `head` is created from `createHead()`
const { headTags, htmlAttrs, bodyAttrs, bodyTags } = renderHeadToString(head)
const finalHTML = `
<html${htmlAttrs}>
<head>
${headTags}
</head>
<body${bodyAttrs}>
<div id="app">${appHTML}</div>
${bodyTags}
</body>
</html>
`
createHead(head?: HeadObject | Ref<HeadObject>)Create the head manager instance.
useHead(head: HeadObject | Ref<HeadObject>)interface HeadObject {
title?: MaybeRef<string>
titleTemplate?: MaybeRef<string> | ((title?: string) => string)
meta?: MaybeRef<HeadAttrs[]>
link?: MaybeRef<HeadAttrs[]>
base?: MaybeRef<HeadAttrs>
style?: MaybeRef<HeadAttrs[]>
script?: MaybeRef<HeadAttrs[]>
noscript?: MaybeRef<HeadAttrs[]>
htmlAttrs?: MaybeRef<HeadAttrs>
bodyAttrs?: MaybeRef<HeadAttrs>
}
interface HeadAttrs {
[attrName: string]: any
}
For meta tags, we use name and property to prevent duplicated tags, you can instead use the key attribute if the same name or property is allowed:
useHead({
meta: [
{
property: "og:locale:alternate",
content: "zh",
key: "zh",
},
{
property: "og:locale:alternate",
content: "en",
key: "en",
},
],
})
To render tags at the end of the <body>, set body: true in a HeadAttrs Object.
useHead({
script: [
{
children: `console.log('Hello world!')`,
body: true,
},
],
})
To set the textContent of an element, use the children attribute:
useHead({
style: [
{
children: `body {color: red}`,
},
],
noscript: [
{
children: `Javascript is required`,
},
],
})
useHead also takes reactive object or ref as the argument, for example:
const head = reactive({ title: "Website Title" })
useHead(head)
const title = ref("Website Title")
useHead({ title })
:warning: Experimental feature Only available when rendering SSR.
To set the render priority of a tag you can use the renderPriority attribute:
useHead({
script: [
{
src: "/not-important-script.js",
},
],
})
useHead({
script: [
// will render first
{
src: "/very-important-script.js",
renderPriority: 1 // default is 10, so will be first
},
],
})
The following special tags have default priorities:
All other tags have a default priority of 10: ,
<Head>Besides useHead, you can also manipulate head tags using the <Head> component:
<script setup lang="ts">
import { Head } from "@vueuse/head"
</script>
<template>
<Head>
<title>Hello World</title>
<base href="/base" />
<html lang="en-US" class="theme-dark" />
</Head>
</template>
Note that you need to use <html> and <body> to set htmlAttrs and bodyAttrs respectively, children for these two tags and self-closing tags like <meta>, <link> and <base> are also ignored.
renderHeadToString(head: Head)HTMLResultexport interface HTMLResult {
// Tags in `<head>`
readonly headTags: string
// Attributes for `<html>`
readonly htmlAttrs: string
// Attributes for `<body>`
readonly bodyAttrs: string
// Tags in `<body>`
readonly bodyTags: string
}
Render the head manager instance to HTML tags in string form.
