I'm trying out React-Router (v4) and I'm having issues starting off the Nav to have one of the Link
's be active
. If I click on any of the Link
tags, then the active stuff starts working. However, I'd like for Home Link
to be active as soon as the app starts since that is the component that loads at the /
route. Is there any way to do this?
Here is my current code:
const Router = () => (
<BrowserRouter>
<div>
<Nav>
<Link activeClassName='is-active' to='/'>Home</Link> {/* I want this to start off as active */}
<Link activeClassName='is-active' to='/about'>About</Link>
</Nav>
<Match pattern='/' exactly component={Home} />
<Match pattern='/about' exactly component={About} />
<Miss component={NoMatch} />
</div>
</BrowserRouter>
)
This is an old, outdated answer for React Router v4
<Link>
no longer has the activeClassName
or activeStyle
properties. In react-router v4 you have to use <NavLink>
if you want to do conditional styling:
const Router = () => (
<BrowserRouter>
<div>
<Nav>
<NavLink exact activeClassName='is-active' to='/'>Home</NavLink>
<NavLink activeClassName='is-active' to='/about'>About</NavLink>
</Nav>
<Match pattern='/' exactly component={Home} />
<Match pattern='/about' exactly component={About} />
<Miss component={NoMatch} />
</div>
</BrowserRouter>
)
I added an exact property to the home <NavLink>
, I'm fairly sure that without it, the home link would always be active since /
would match /about
and any other pages you have.
React Router v6:
Source: Active NavLink Classes with React Router
Now you can use the className
property which now accepts a function and passes an isActive
boolean property, like this:
<NavLink
to="users"
className={({ isActive }) => (isActive ? 'active' : 'inactive')}
>
Users
</NavLink>
You can also adding multiple classes too, since v6 is out:
<NavLink
to="users"
className={({ isActive }) =>
isActive ? 'bg-green-500 font-bold' : 'bg-red-500 font-thin'
}
>
Users
</NavLink>
Live demo: Active NavLink Classes with React Router
import { NavLink, useMatch, useResolvedPath } from 'react-router-dom';
const CustomNavLink = ({ to, title }) => {
let resolved = useResolvedPath(to);
let match = useMatch({ path: resolved.pathname, end: true });
return (
<NavLink to={to} className={`d-flex align-items-center py-2 px-4 ${match ? 'cta-btn' : 'c-n-b-link'}`} >
<span className='ms-1 f-w-600'>{title}</span>
</NavLink>
)
}
For React router V6
The above custom component will return a navlink that an active class can be activated whenever the path matches the given to
path.
Navlink
has an active class .active
so if you pass in your own class like mynavlinkclass
and target mynavlinkclass.active
you can style the link when its active. This is Navlink
from React router dom V6
In my case <NavLink />
automatically set active
class to items so I use the following method
myComponet.js
<ListItem component={NavLink} to="/somewhere" className="myactive" > something </ListItem>
myStyle.css
a.active.myactive {
// some styles
}
As an addition to @Nick's answer (React Router v6), for those who needs the active navigation state in the upper context..
Conditional rendering might be a use case for the need. For ex: if it is active render the filled icon otherwise render the regular one.
This could be achieved by finding the route that we are currently in and then we can do the conditional rendering operation however it would be a little cumbersome.
Instead, we can write a function that modifies the state in Navlink
's style prop as following..
const [active, setActive] = useState('home')
const activate = (isActive, path, activeStyle, nonActiveStyle) => {
if (isActive) {
setActive(path)
return activeStyle
}
return nonActiveStyle
}
return (
<nav>
<NavLink
to="/"
style={(activeNav) => activate(activeNav.isActive, 'home')}
>
{active === 'home' ? <HomeFill /> : <Home />}
</NavLink>
<NavLink
to="/profile"
style={(activeNav) => activate(activeNav.isActive, 'profile')}
>
{active === 'profile' ? <ProfileFilled /> : <Profile />}
</NavLink>
</nav>
)
In react-router-dom Version 5.3.0
I have used the following to enable the active link
classes:
active: {
// background: 'linear-gradient(180deg, #008b32 0%, #cddc39 100%)',
// backgroundColor: 'slategray',
borderBottom: '1px solid white',
borderRadius: '6px',
boxShadow: 'rgba(6, 24, 44, 0.4) 0px 0px 0px 2px , rgba(6, 24, 44, 0.65) 0px 4px 6px -1px , rgba(255, 255, 255, 0.08) 0px 1px 0px inset',
color: 'white',
fontSize: '14px',
listStyle: 'none',
marginLeft: '16px',
padding: '5px',
textDecoration: 'none',
textTransform: 'uppercase',
transition: 'all 0.1s cubic-bezier(0.42, 0.02, 0.06, 0.05) 0.1s',
},
link: {
'&:hover': {
borderBottom: '1px solid white',
borderRadius: '6px',
boxShadow: 'rgba(6, 24, 44, 0.4) 0px 0px 0px 2px , rgba(6, 24, 44, 0.65) 0px 4px 6px -1px , rgba(255, 255, 255, 0.08) 0px 1px 0px inset',
color: 'white',
padding: '5px',
transition: 'all 0.1s cubic-bezier(0.42, 0.02, 0.06, 0.05) 0.1s',
},
color: '#ddf1f9',
fontSize: '14px',
listStyle: 'none',
marginLeft: '16px',
textDecoration: 'none',
textTransform: 'uppercase'
},
NavLink.js
import React from "react";
import { useLocation } from "react-router-dom";
const NavLinks = classes => {
const pathname = useLocation().pathname
return (
<nav>
<ul className={classes.navlinks}>
<li>
<Link
className={`${pathname === '/' ? classes.active : classes.link}`}
to='/'
>
Login
</Link>
</li>
<li>
<Link
className={`${pathname === '/dashboard' ? classes.active : classes.link}`}
to='/dashboard'
>
Dashboard
</Link>
</li>
</ul>
</nav>
)
}
