Next.js: How to Set Page Title and Meta Description
( 27 Articles)
In Next.js, you can set the title, description, and other metadata for a page by using the <Head> component. Import it like this:
import Head from 'next/head'Examples
Static Content
The code:
// pages/index.js
// KindaCode.com
import Head from 'next/head'
export default function Home(props) {
return <>
<Head>
<title>KindaCode.com</title>
<meta name='description' content='I hope this tutorial is helpful for you' />
</Head>
<div style={{ padding: 30 }}>
<h1>Hello there!</h1>
</div>
</>
}Output:
Dynamic Routes & Dynamic Content
You can fetch data from a backend by using getStaticProps, getStaticPaths, or getServerSideProps and use this data to set the page title and description like this:
// pages/[id].js
import Head from 'next/head'
const Product = (props) => {
const { title, description } = props;
return <>
<Head>
<title>{title}</title>
<meta name='description' content={description} />
</Head>
{/* page content here */}
<div>
{content}
</div>
</>
}
export default Product
export async function getServerSideProps(context) {
// Retrieve id
const { params } = context;
const id = params.id;
// Fetch data
const result = await fetch(`[your API]/${id}`);
const data = await result.json();
return {
props: {
title: data.title,
description: data.description,
content: data.content
}
}
}Note: This isn’t a complete example. You need to make the necessary changes for it to work (use your own API URL, inspect data structure, etc).
Setting Global Metadata
If you want to set the same metadata for all pages, you can put a component in pages/_app.js, like this:
// pages/_app.js
import '../styles/globals.css'
import Head from 'next/head'
function MyApp({ Component, pageProps }) {
return <>
<Head>
<meta name="author" content="John Doe"/>
</Head>
<Component {...pageProps} />
</>
}
export default MyAppNote: If have multiple <Head> components on a page and its child components, Next.js will automatically merge their content and your app will never crash because of conflict. The latest values would be used.
