<Link>

Examples

<Link> is a React component that extends the HTML <a> element to provide prefetching and client-side navigation between routes. It is the primary way to navigate between routes in Next.js.

For an example, consider a pages directory with the following files:

  • pages/index.js
  • pages/about.js
  • pages/blog/[slug].js

We can have a link to each of these pages like so:

import Link from 'next/link'
 
function Home() {
  return (
    <ul>
      <li>
        <Link href="/">Home</Link>
      </li>
      <li>
        <Link href="/about">About Us</Link>
      </li>
      <li>
        <Link href="/blog/hello-world">Blog Post</Link>
      </li>
    </ul>
  )
}
 
export default Home

Props

Here's a summary of the props available for the Link Component:

PropExampleTypeRequired
hrefhref="/dashboard"String or ObjectYes
replacereplace={false}Boolean-
scrollscroll={false}Boolean-
prefetchprefetch={false}Boolean-

Good to know: <a> tag attributes such as className or target="_blank" can be added to <Link> as props and will be passed to the underlying <a> element.

href (required)

The path or URL to navigate to.

<Link href="/dashboard">Dashboard</Link>

href can also accept an object, for example:

// Navigate to /about?name=test
<Link
  href={{
    pathname: '/about',
    query: { name: 'test' },
  }}
>
  About
</Link>

replace

Defaults to false. When true, next/link will replace the current history state instead of adding a new URL into the browser’s history stack.

app/page.tsx
import Link from 'next/link'
 
export default function Page() {
  return (
    <Link href="/dashboard" replace>
      Dashboard
    </Link>
  )
}

scroll

Defaults to true. The default behavior of <Link> is to scroll to the top of a new route or to maintain the scroll position for backwards and forwards navigation. When false, next/link will not scroll to the top of the page after a navigation.

app/page.tsx
import Link from 'next/link'
 
export default function Page() {
  return (
    <Link href="/dashboard" scroll={false}>
      Dashboard
    </Link>
  )
}

Good to know:

  • Next.js will scroll to the Page if it is not visible in the viewport upon navigation.

prefetch

Prefetching happens when a <Link /> component enters the user's viewport (initially or through scroll). Next.js prefetches and loads the linked route (denoted by the href) and data in the background to improve the performance of client-side navigations. Prefetching is only enabled in production.

  • true (default): The full route and its data will be prefetched.
  • false: Prefetching will not happen when entering the viewport, but will happen on hover. If you want to completely remove fetching on hover as well, consider using an <a> tag or incrementally adopting the App Router, which enables disabling prefetching on hover too.
pages/index.tsx
import Link from 'next/link'
 
export default function Page() {
  return (
    <Link href="/dashboard" prefetch={false}>
      Dashboard
    </Link>
  )
}

Other Props

legacyBehavior

An <a> element is no longer required as a child of <Link>. Add the legacyBehavior prop to use the legacy behavior or remove the <a> to upgrade. A codemod is available to automatically upgrade your code.

Good to know: when legacyBehavior is not set to true, all anchor tag properties can be passed to next/link as well such as, className, onClick, etc.

passHref

Forces Link to send the href property to its child. Defaults to false

scroll

Scroll to the top of the page after a navigation. Defaults to true

shallow

Update the path of the current page without rerunning getStaticProps, getServerSideProps or getInitialProps. Defaults to false

locale

The active locale is automatically prepended. locale allows for providing a different locale. When false href has to include the locale as the default behavior is disabled.

Examples

Linking to Dynamic Routes

For dynamic routes, it can be handy to use template literals to create the link's path.

For example, you can generate a list of links to the dynamic route pages/blog/[slug].js

pages/blog/index.js
import Link from 'next/link'
 
function Posts({ posts }) {
  return (
    <ul>
      {posts.map((post) => (
        <li key={post.id}>
          <Link href={`/blog/${post.slug}`}>{post.title}</Link>
        </li>
      ))}
    </ul>
  )
}
 
export default Posts

If the child is a custom component that wraps an <a> tag

If the child of Link is a custom component that wraps an <a> tag, you must add passHref to Link. This is necessary if you’re using libraries like styled-components. Without this, the <a> tag will not have the href attribute, which hurts your site's accessibility and might affect SEO. If you're using ESLint, there is a built-in rule next/link-passhref to ensure correct usage of passHref.

import Link from 'next/link'
import styled from 'styled-components'
 
// This creates a custom component that wraps an <a> tag
const RedLink = styled.a`
  color: red;
`
 
function NavLink({ href, name }) {
  return (
    <Link href={href} passHref legacyBehavior>
      <RedLink>{name}</RedLink>
    </Link>
  )
}
 
export default NavLink
  • If you’re using emotion’s JSX pragma feature (@jsx jsx), you must use passHref even if you use an <a> tag directly.
  • The component should support onClick property to trigger navigation correctly

If the child is a functional component

If the child of Link is a functional component, in addition to using passHref and legacyBehavior, you must wrap the component in React.forwardRef:

import Link from 'next/link'
 
// `onClick`, `href`, and `ref` need to be passed to the DOM element
// for proper handling
const MyButton = React.forwardRef(({ onClick, href }, ref) => {
  return (
    <a href={href} onClick={onClick} ref={ref}>
      Click Me
    </a>
  )
})
 
function Home() {
  return (
    <Link href="/about" passHref legacyBehavior>
      <MyButton />
    </Link>
  )
}
 
export default Home

With URL Object

Link can also receive a URL object and it will automatically format it to create the URL string. Here's how to do it:

import Link from 'next/link'
 
function Home() {
  return (
    <ul>
      <li>
        <Link
          href={{
            pathname: '/about',
            query: { name: 'test' },
          }}
        >
          About us
        </Link>
      </li>
      <li>
        <Link
          href={{
            pathname: '/blog/[slug]',
            query: { slug: 'my-post' },
          }}
        >
          Blog Post
        </Link>
      </li>
    </ul>
  )
}
 
export default Home

The above example has a link to:

  • A predefined route: /about?name=test
  • A dynamic route: /blog/my-post

You can use every property as defined in the Node.js URL module documentation.

Replace the URL instead of push

The default behavior of the Link component is to push a new URL into the history stack. You can use the replace prop to prevent adding a new entry, as in the following example:

<Link href="/about" replace>
  About us
</Link>

Disable scrolling to the top of the page

The default behavior of Link is to scroll to the top of the page. When there is a hash defined it will scroll to the specific id, like a normal <a> tag. To prevent scrolling to the top / hash scroll={false} can be added to Link:

<Link href="/#hashid" scroll={false}>
  Disables scrolling to the top
</Link>

Middleware

It's common to use Middleware for authentication or other purposes that involve rewriting the user to a different page. In order for the <Link /> component to properly prefetch links with rewrites via Middleware, you need to tell Next.js both the URL to display and the URL to prefetch. This is required to avoid un-necessary fetches to middleware to know the correct route to prefetch.

For example, if you want to serve a /dashboard route that has authenticated and visitor views, you may add something similar to the following in your Middleware to redirect the user to the correct page:

middleware.js
export function middleware(req) {
  const nextUrl = req.nextUrl
  if (nextUrl.pathname === '/dashboard') {
    if (req.cookies.authToken) {
      return NextResponse.rewrite(new URL('/auth/dashboard', req.url))
    } else {
      return NextResponse.rewrite(new URL('/public/dashboard', req.url))
    }
  }
}

In this case, you would want to use the following code in your <Link /> component:

import Link from 'next/link'
import useIsAuthed from './hooks/useIsAuthed'
 
export default function Page() {
  const isAuthed = useIsAuthed()
  const path = isAuthed ? '/auth/dashboard' : '/public/dashboard'
  return (
    <Link as="/dashboard" href={path}>
      Dashboard
    </Link>
  )
}

Good to know: If you're using Dynamic Routes, you'll need to adapt your as and href props. For example, if you have a Dynamic Route like /dashboard/authed/[user] that you want to present differently via middleware, you would write: <Link href={{ pathname: '/dashboard/authed/[user]', query: { user: username } }} as="/dashboard/[user]">Profile</Link>.
