next/link

Examples

Before moving forward, we recommend you to read Routing Introduction first.

Client-side transitions between routes can be enabled via the Link component exported by next/link.

An example of linking to / and /about:

import Link from 'next/link'

function Home() {
  return (
    <ul>
      <li>
        <Link href="/">
          <a>Home</a>
        </Link>
      </li>
      <li>
        <Link href="/about">
          <a>About Us</a>
        </Link>
      </li>
    </ul>
  )
}

export default Home

Link accepts the following props:

  • href - The path inside pages directory. This is the only required prop
  • as - The path that will be rendered in the browser URL bar. Used for dynamic routes
  • passHref - Forces Link to send the href property to its child. Defaults to false
  • prefetch - Prefetch the page in the background. Defaults to true. Any <Link /> that is in the viewport (initially or through scroll) will be preloaded. Pages using Static Generation will preload JSON files with the data for faster page transitions.
  • replace - Replace the current history state instead of adding a new url into the stack. 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

External URLs, and any links that don't require a route navigation using /pages, don't need to be handled with Link; use the anchor tag for such cases instead.

Dynamic routes

A Link to a dynamic route is a combination of the href and as props. A link to the page pages/post/[pid].js will look like this:

<Link href="/post/[pid]" as="/post/abc">
  <a>First Post</a>
</Link>

href is a file system path used by the page and it shouldn't change at runtime. as on the other hand, will be dynamic most of the time according to your needs. Here's an example of how to create a list of links:

const pids = ['id1', 'id2', 'id3']
{
  pids.map((pid) => (
    <Link href="/post/[pid]" as={`/post/${pid}`}>
      <a>Post {pid}</a>
    </Link>
  ))
}

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 might hurt your site’s SEO.

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 }) {
  // Must add passHref to Link
  return (
    <Link href={href} passHref>
      <RedLink>{name}</RedLink>
    </Link>
  )
}

export default NavLink

Note: If you’re using emotion’s JSX pragma feature (@jsx jsx), you must use passHref even if you use an <a> tag directly.

If the child is a function component

If the child of Link is a function component, in addition to using passHref, 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>
      <MyButton />
    </Link>
  )
}

export default Home

With URL Object

Link can also receive an 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 (
    <div>
      <Link href={{ pathname: '/about', query: { name: 'test' } }}>
        <a>About us</a>
      </Link>
    </div>
  )
}

export default Home

The above example will be a link to /about?name=test. 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>
  <a>About us</a>
</Link>

Using a component that supports onClick

Link supports any component that supports the onClick event, in the case you don't provide an <a> tag, consider the following example:

<Link href="/about">
  <img src="/static/image.png" alt="image" />
</Link>

The child of Link is <img> instead of <a>. Link will send the onClick property to <img> but won't pass the href property.

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="/?counter=10" scroll={false}>
  <a>Disables scrolling to the top</a>
</Link>
