How to Create a Reusable Active Link Component in Next.js App Router

Providing a seamless and intuitive navigation experience is crucial for building engaging web applications. One way to achieve this is by implementing an active link component that visually highlights the current page, helping users effortlessly track their location within the application. In this tutorial, we'll dive into creating a reusable active link component for a Next.js application, enhancing overall usability and user experience.


Before we begin, ensure that you have a basic understanding of Next.js and React. Additionally, make sure that Node.js is installed on your machine.

Getting Started

Let's kickstart the process by setting up a new Next.js project and installing the necessary dependencies.

Step 1: Create a New Next.js Project

Open your terminal and run the following command to create a new Next.js project:

npx create-next-app@latest nextjs-active-link

Once the project is generated, navigate to the project directory:

cd nextjs-active-link

Next, install the required dependencies:

npm install tailwind-merge clsx

Step 2: Set Up Components Folder

Create a new folder named components inside the src directory. Within this folder, create a file named active-link.tsx to house our active link component.

Step 3: Implement Classnames Utility

In the utils folder, create a file named cn.ts to define a utility function for handling class names. Insert the following code:

import { type ClassValue, clsx } from "clsx";
import { twMerge } from "tailwind-merge";
export function cn(...inputs: ClassValue[]) {
  return twMerge(clsx(inputs));

This utility function will help us manage class names more efficiently and make it easier to apply conditional styles to our components.

Step 4: Develop the Active Link Component

Inside active-link.tsx, build the active link component using the provided code snippet. Ensure to mark the file as client due to the usage of the usePathname hook, which is only available on the client side.

"use client";
import Link from "next/link";
import { usePathname } from "next/navigation";
import { cn } from "~/utils/cn";
interface Props extends React.ComponentPropsWithoutRef<typeof Link> {
  className?: string;
  activeClassName?: string;
export const ActiveLink = (props: Props) => {
  const pathname = usePathname();
  const isActive = pathname === props.href;
  const activeClassName = props.activeClassName ?? "text-red-500";
  return (
      className={cn(props.className, isActive && activeClassName)}

In this component, we're using the usePathname hook from Next.js to get the current URL path. We then compare this path with the href prop passed to the component to determine if the link is currently active or not. Based on this condition, we apply the activeClassName style to the link, allowing us to visually distinguish the active link from the rest.

The cn utility function we created earlier is used to merge the className prop with the activeClassName conditionally, making it easier to manage and apply multiple class names.

Step 5: Integrate Active Link in Layout

To use the ActiveLink component within your application, you'll need to import it and employ it to create navigational links. The component will automatically apply the designated active styling when the link corresponds to the current path.

Here's an example of how you can integrate the ActiveLink component in your application layout file (layout.tsx):

import type { Metadata } from "next";
import { Inter } from "next/font/google";
import "./globals.css";
import { ActiveLink } from "~/components/active-link"; // Import the ActiveLink component
const inter = Inter({ subsets: ["latin"] });
export const metadata: Metadata = {
  title: "Create Next App",
  description: "Generated by create next app",
export default function RootLayout({
}: Readonly<{
  children: React.ReactNode;
}>) {
  return (
    <html lang="en">
      <body className={inter.className}>
        <nav className="flex items-center justify-center gap-10 container mx-auto py-10">
          {/* Use the ActiveLink component */}
          {[...Array(10)].map((_, i) => (
              className="py-1 px-2"
              activeClassName="bg-blue-500 !text-white"
              Link {i}

In this example, we're using the ActiveLink component to create ten navigation links. The className prop sets the default styles for the links, while the activeClassName prop defines the styles to be applied when a link is active. In this case, the active link will have a blue background and white text color.


Incorporating a reusable active link component into your Next.js application can significantly enhance the navigation experience for your users. By providing clear visual cues for the current page, users can effortlessly track their location within the application, leading to increased engagement and satisfaction.

With the step-by-step guide provided in this tutorial, you now have the knowledge and tools to implement an active link component and take your Next.js application to new heights of usability and accessibility.
