Link
Enable fast client-side navigation with the built-in `next/link` component.
<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.
Basic usage:
Reference
The following props can be passed to the <Link>
component:
Prop | Example | Type | Required |
---|---|---|---|
href | href="/dashboard" | String or Object | Yes |
replace | replace={false} | Boolean | - |
scroll | scroll={false} | Boolean | - |
prefetch | prefetch={false} | Boolean | - |
legacyBehavior | legacyBehavior={true} | Boolean | - |
passHref | passHref={true} | Boolean | - |
shallow | shallow={false} | Boolean | - |
locale | locale="fr" | String or 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.
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.
scroll
Defaults to true
. The default scrolling behavior of <Link>
in Next.js is to maintain scroll position, similar to how browsers handle back and forwards navigation. When you navigate to a new Page, scroll position will stay the same as long as the Page is visible in the viewport. However, if the Page is not visible in the viewport, Next.js will scroll to the top of the first Page element.
When scroll = {false}
, Next.js will not attempt to scroll to the first Page element.
Good to know: Next.js checks if scroll: false
before managing scroll behavior. If scrolling is enabled, it identifies the relevant DOM node for navigation and inspects each top-level element. All non-scrollable elements and those without rendered HTML are bypassed, this includes sticky or fixed positioned elements, and non-visible elements such as those calculated with getBoundingClientRect
. Next.js then continues through siblings until it identifies a scrollable element that is visible in the viewport.
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 navigation's. Prefetching is only enabled in production.
The following values can be passed to the prefetch
prop:
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.
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
. See the passing a functional component example for more information.
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
The following examples demonstrate how to use the <Link>
component in different scenarios.
Linking to dynamic route segments
For dynamic route segments, 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
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
.
- If you’re using emotion’s JSX pragma feature (
@jsx jsx
), you must usepassHref
even if you use an<a>
tag directly. - The component should support
onClick
property to trigger navigation correctly.
Nesting 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
:
Passing a URL Object
Link
can also receive a URL object and it will automatically format it to create the URL string:
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:
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
:
Prefetching links in 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 can add the following in your Middleware to redirect the user to the correct page:
In this case, you would want to use the following code in your <Link />
component:
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>
.
