Next.js - Meta Data

Next.js - Meta Data​

In Next.js, we can serve modify the head section of each react pages very easily with the help of <Head> react component which is inbuilt.

Let's update the nextjs project used in Pages chapter.

Update index.js as follows −

import Link from 'next/link'
import Head from 'next/head'

function HomePage() {
   return (
      <>
         <Head>
            <title>Welcome to Next.js!</title>
         </Head>
         <div>Welcome to Next.js!</div>
         <Link href="/posts/first"><a>First Post</a></Link>
         <br/>
         <img src="/logo.png" alt="TutorialsPoint Logo" />
      </>	    
   )
}

export default HomePage

Update first.js as follows −

import Link from 'next/link'
import Head from 'next/head'

export default function FirstPost() {
   return (
      <>
      <Head>
         <title>My First Post</title>
      </Head>
      <h1>My First Post</h1>
      <h2>
         <Link href="/">
            <a>Home</a>
         </Link>
      </h2>
      </>	  
   )
}

Here we've added a reference to logo.png in index.js file.
