Highlight Active When Click on Link ReactJS

Highlighting an active link when clicked is a common and essential feature in modern web applications. In ReactJS, achieving this dynamic behavior is surprisingly straightforward, allowing developers to create intuitive and user-friendly navigation experiences. This article dives into various methods and best practices for implementing “Highlight Active When Click On Link Reactjs” functionality, empowering you to enhance your React projects with polished navigation.

Understanding the Importance of Active Link Highlighting

Clear visual cues are crucial for user navigation. Highlighting the currently active link provides context, indicating the user’s current location within the website or application. This simple visual feedback significantly improves user experience and reduces confusion, especially in complex navigation structures.

Implementing Active Link Highlighting in ReactJS

There are several approaches to implementing this functionality in React, each with its own advantages and disadvantages.

Using NavLink from react-router-dom

The simplest and most recommended approach is using the NavLink component provided by the react-router-dom library. NavLink adds an active class to the link when its to prop matches the current URL. You can then style this active class in your CSS to visually highlight the active link.

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

<nav>
  <NavLink to="/" exact>Home</NavLink>
  <NavLink to="/about">About</NavLink>
  <NavLink to="/contact">Contact</NavLink>
</nav>

.active {
  font-weight: bold;
  color: blue;
}

The exact prop ensures the “Home” link is only active when the URL is exactly “/”, preventing it from also being highlighted on sub-routes like “/about”.

Using State Management

For more complex scenarios, managing the active link state directly might be necessary. You can store the active route in your component’s state and use conditional rendering to apply the highlight.

import { useState } from 'react';
import { Link } from 'react-router-dom';

function Navigation() {
  const [activeLink, setActiveLink] = useState('/');

  return (
    <nav>
      <Link to="/" className={activeLink === '/' ? 'active' : ''} onClick={() => setActiveLink('/')}>Home</Link>
      <Link to="/about" className={activeLink === '/about' ? 'active' : ''} onClick={() => setActiveLink('/about')}>About</Link>
      <Link to="/contact" className={activeLink === '/contact' ? 'active' : ''} onClick={() => setActiveLink('/contact')}>Contact</Link>
    </nav>
  );
}

Styling the Active Link

The active class provides flexibility in styling. You can apply various visual cues, such as:

• Changing the background color: background-color: lightgray;
• Changing the text color: color: red;
• Adding an underline: text-decoration: underline;
• Making the text bold: font-weight: bold;

Choose a style that complements your overall design and provides clear visual feedback to the user.

Best Practices for Active Link Highlighting

• Consistency: Maintain a consistent highlighting style across your entire application.
• Accessibility: Ensure sufficient color contrast for users with visual impairments.
• Performance: Avoid unnecessary re-renders by optimizing your state management logic.

Conclusion

Highlighting active when click on link reactjs enhances user experience and provides clear navigation cues. Using NavLink from react-router-dom is the most straightforward approach, while state management provides more flexibility for complex scenarios. By implementing these techniques and following best practices, you can create polished and user-friendly navigation in your React applications.
