<NavLink>
A <NavLink>
is a special kind of <Link>
that knows whether or not it is "active", "pending", or "transitioning". This is useful in a few different scenarios:
- When building a navigation menu, such as a breadcrumb or a set of tabs where you'd like to show which of them is currently selected
- It provides useful context for assistive technology like screen readers
- It provides a "transitioning" value to give you finer-grained control over View Transitions
import { NavLink } from "react-router-dom";
<NavLink
to="/messages"
className={({ isActive, isPending }) =>
isPending ? "pending" : isActive ? "active" : ""
}
>
Messages
</NavLink>;
Default active
class
By default, an active
class is added to a <NavLink>
component when it is active so you can use CSS to style it.
<nav id="sidebar">
<NavLink to="/messages" />
</nav>
#sidebar a.active {
color: red;
}
className
The className
prop works like a normal className, but you can also pass it a function to customize the classNames applied based on the active and pending state of the link.
<NavLink
to="/messages"
className={({ isActive, isPending, isTransitioning }) =>
[
isPending ? "pending" : "",
isActive ? "active" : "",
isTransitioning ? "transitioning" : "",
].join(" ")
}
>
Messages
</NavLink>
style
The style
prop works like a normal style prop, but you can also pass it a function to customize the styles applied based on the active and pending state of the link.
<NavLink
to="/messages"
style={({ isActive, isPending, isTransitioning }) => {
return {
fontWeight: isActive ? "bold" : "",
color: isPending ? "red" : "black",
viewTransitionName: isTransitioning ? "slide" : "",
};
}}
>
Messages
</NavLink>
children
You can pass a render prop as children to customize the content of the <NavLink>
based on the active and pending state, which is useful to change styles on internal elements.
<NavLink to="/tasks">
{({ isActive, isPending, isTransitioning }) => (
<span className={isActive ? "active" : ""}>Tasks</span>
)}
</NavLink>
end
The end
prop changes the matching logic for the active
and pending
states to only match to the "end" of the NavLink's to
path. If the URL is longer than to
, it will no longer be considered active.
Link | Current URL | isActive |
---|---|---|
<NavLink to="/tasks" /> | /tasks | true |
<NavLink to="/tasks" /> | /tasks/123 | true |
<NavLink to="/tasks" end /> | /tasks | true |
<NavLink to="/tasks" end /> | /tasks/123 | false |
<NavLink to="/tasks/" end /> | /tasks | false |
<NavLink to="/tasks/" end /> | /tasks/ | true |
A note on links to the root route
<NavLink to="/">
is an exceptional case because every URL matches /
. To avoid this matching every single route by default, it effectively ignores the end
prop and only matches when you're at the root route.
caseSensitive
Adding the caseSensitive
prop changes the matching logic to make it case sensitive.
Link | URL | isActive |
---|---|---|
<NavLink to="/SpOnGe-bOB" /> | /sponge-bob | true |
<NavLink to="/SpOnGe-bOB" caseSensitive /> | /sponge-bob | false |
aria-current
When a NavLink
is active it will automatically apply <a aria-current="page">
to the underlying anchor tag. See aria-current on MDN.
reloadDocument
The reloadDocument
property can be used to skip client side routing and let the browser handle the transition normally (as if it were an <a href>
).
unstable_viewTransition
The unstable_viewTransition
prop enables a View Transition for this navigation by wrapping the final state update in document.startViewTransition()
. By default, during the transition a transitioning
class will be added to the <a>
element that you can use to customize the view transition.
a.transitioning p {
view-transition-name: "image-title";
}
a.transitioning img {
view-transition-name: "image-expand";
}
<NavLink to={to} unstable_viewTransition>
<p>Image Number {idx}</p>
<img src={src} alt={`Img ${idx}`} />
</NavLink>
You may also use the className
/style
props or the render props passed to children
to further customize based on the isTransitioning
value.
<NavLink to={to} unstable_viewTransition>
{({ isTransitioning }) => (
<>
<p
style={{
viewTransitionName: isTransitioning
? "image-title"
: "",
}}
>
Image Number {idx}
</p>
<img
src={src}
alt={`Img ${idx}`}
style={{
viewTransitionName: isTransitioning
? "image-expand"
: "",
}}
/>
</>
)}
</NavLink>
