I am using react-router-dom: 4.2.2. I can add activeClassName to the current URL. But surprisingly the class is always added to root URL.

While visiting a page, for example the error page like the screenshot below, the home navlink also getting the activeClass.

enter image description here

Update: In the above screenshot I have showed that I visited http://localhost:3000/#/error. So, the active-link should be added to the Love Error? NavLink only. But as you can see it is also added to Home NavLink too.

Here is my navbar code:

import React from 'react';
import { NavLink } from 'react-router-dom';

export const NavigationBar = () => (
  <ul className="horizontal-menu">
    <li> <NavLink to = '/' activeClassName="active-link">Home</NavLink> </li>
    <li> <NavLink to = '/about' activeClassName="active-link">About Us</NavLink> </li>
    <li> <NavLink to = '/error' activeClassName="active-link">Love Error?</NavLink> </li>
  </ul>
)

For routing I have used the following Switch:

<Switch>
  <Route exact path = '/' component = {Home} />
  <Route exact path = '/about' component = {AboutUs} />
  <Route exact path = '/error' component = {Error404} />
  <Route path = "/news/:id" component = {NewsDetail} />
  <Route path="*" component={Error404} />
</Switch>

How can I get the expected behavior?

You have to use isActive={} to add additional verification to ensure whether the link is active.

document

Working jsFiddle. (fiddle is not created by me)

Code you need to add is like below

Example in jsfiddle

<li><NavLink to="/" isActive={checkActive}>Home</NavLink></li>

Change in your code

<li> <NavLink to='/' activeClassName="active-link" isActive={checkActive}>Home</NavLink> </li>

check the isActive prop and "checkActive" is a function.

const checkActive = (match, location) => {
    //some additional logic to verify you are in the home URI
    if(!location) return false;
    const {pathname} = location;
    console.log(pathname);
    return pathname === "/";
}

Another config you can use is "exact" but It is not possible to demonstrate it in a jsFiddle. I think the code would be like

<li> <NavLink exact to='/' activeClassName="active-link">Home</NavLink> </li>

Hope this helps. And let me know if you need more info.

I've found that adding exact before the first activeClassName works as well. So for example, your set up can be:

export const NavigationBar = () => (
  <ul className="horizontal-menu">
    <li><NavLink to='/' exact activeClassName="active-link">Home</NavLink> 
    </li>
    ....remaining NavLinks
  </ul>
)

You can use exact keyword for active class such as

<NavLink exact to ='/'>Home</NavLink>

it will generate like that

<a href="/" class="active" aria-current="page">Home</a>

and if you will get another page then it will be like that

<a href="/">Home</a>

I recently came across this issue and solved it by simply adding:

import { withRouter } from 'react-router-dom';

and then wrapped the component with:

export default withRouter(Component);

Change in your code

<li> <NavLink to='/' activeClassName="active-link" isActive={checkActive}>Home</NavLink> </li>

and then

const checkActive = (match, location) => {
  console.log(location);
  if (!location) return false;
  const { pathname } = location;
  const { url } = match;
  return pathname === url ? true : false;
};
  • note *
const { pathname } = location;
const { url } = match;
return pathname === url ? true : false;

I am learning React now and just came across the same problem. I tried the following and it worked for me.

So, I have 3 navigational links.

<li><NavLink to="/home">Home</NavLink></li>
<li><NavLink to="/about">About</NavLink></li>
<li><NavLink to="/contact">Contact</NavLink></li>

But I added 4 routes.

<Route exact path="/" component={Home}></Route>
<Route path="/home" component={Home}></Route>
<Route path="/about" component={About}></Route>
<Route path="/contact" component={Contact}></Route>

I added 2 routes (/ and /home) for the same component (Home). This way, the react-router-dom seems to add the class 'active' only to the link that you click.

Working fine for me

<ul className="menu nav navbar-nav">
      <li><NavLink exact to="/" activeClassName="active-link active2">Home</NavLink></li>
      <li><NavLink to="/financial-summary" activeClassName="active-link active2">Financial Summary</NavLink></li>
      <li><NavLink to="/account-statement" activeClassName="active-link active2">Account Statement</NavLink></li>
      <li><NavLink to="/tools" activeClassName="active-link active2">Tools</NavLink></li>
      <li><NavLink to="/service-charges" activeClassName="active-link active2">Service Charges & Important Information</NavLink></li>
    </ul>

css

.active2, .active2 a:link, .active2 a:visited{
    background: #004B8D !important;
    color: #FFFFFF !important;
    border-top-left-radius: 5px;
    border-top-right-radius: 5px;
}

If you're trying to use <Navlink> on single page website and anchor-links, make sure to replace <BrowserRouter> with <HashRouter>!

I had to remove the slash to reach my anchor text: <HashRouter hashType='noslash'>

With this setup,

<li><NavLink to="about">About</NavLink></li>

will render

<a href="#about" aria-current="page" class="active">About</a>

I am using LinkContainer from react-router-bootstrap, I was still having an issue like this. The home link was always active.

I have solved it by using an exact keyword for the path of the link like this. I hope if you will use this and have any issue regarding this, so it can help. cheers.

Header.js component :

  <LinkContainer to="/" exact>
     <Nav.Link>
       <i className="fas fa-home mr-1"></i>Home
     </Nav.Link>
  </LinkContainer>

and App.js component :

 <Route path="/" component={HomeScreen} exact />
 <Route path="/about" component={AboutScreen} exact />
 <Route path="/blogs" component={BlogScreen} exact />
