Next.js

When linking between pages on websites you generally use the <a> HTML tag.

In Next.js, you use the Link Component from next/link to wrap the <a> tag. <Link> allows you to do client-side navigation to a different page in the application.

Using <Link>

First, in pages/index.js, import the Link component from next/link by adding this line at the top:

import Link from 'next/link'

Then modify this line in the h1 tag:

Learn <a href="https://nextjs.org">Next.js!</a>

To this:

Read <Link href="/posts/first-post"><a>this page!</a></Link>

Next, replace the content of pages/posts/first-post.js with the following:

import Link from 'next/link'

export default function FirstPost() {
  return (
    <>
      <h1>First Post</h1>
      <h2>
        <Link href="/">
          <a>Back to home</a>
        </Link>
      </h2>
    </>
  )
}

As you can see, the Link component is similar to using <a> tags, but instead of <a href="…">, you use <Link href="…"> and put an <a> tag inside.

Let’s check to see it works. You now should have a link on each page, allowing you to go back and forth:
