Implementing Redirects in Next.js | Updated 2024

3

Redirects are a crucial feature for web applications, enabling you to forward users from one URL to another. This can be useful for various purposes, such as handling deprecated routes, managing authentication, and more. In this guide, we will explore how to implement redirects in a Next.js application.

Prerequisites

Ensure you have the following installed:

• Node.js
• npm or yarn
• A Next.js project

Steps for Implementing Redirects in Next.js

Step 1: Setting Up the Next.js Project

If you don’t have a Next.js project set up already, you can create one using the following command:

npx create-next-app my-nextjs-redirects
# or
yarn create next-app my-nextjs-redirects

Navigate to your project directory:

cd my-nextjs-redirects

Step 2: Configuring Redirects in Next.js

Next.js provides a simple way to configure redirects through the next.config.js file.

Open or create next.config.js in the root of your project:

// next.config.js
module.exports = {
  async redirects() {
    return [
      {
        source: '/old-route',
        destination: '/new-route',
        permanent: true, // this will send a 308 permanent redirect
      },
      {
        source: '/temporary-redirect',
        destination: '/new-temp-route',
        permanent: false, // this will send a 307 temporary redirect
      },
    ];
  },
};

In this example, /old-route permanently redirects to /new-route, and /temporary-redirect temporarily redirects to /new-temp-route.

Step 3: Creating Pages for Redirects

Create the pages referenced in your redirects to test them.

Create a new file pages/new-route.js

// pages/new-route.js
export default function NewRoute() {
  return (
    <div>
      <h1>New Route</h1>
      <p>This is the new route page.</p>
    </div>
  );
}

Create a new file pages/new-temp-route.js

// pages/new-temp-route.js
export default function NewTempRoute() {
  return (
    <div>
      <h1>New Temporary Route</h1>
      <p>This is the new temporary route page.</p>
    </div>
  );
}

Step 4: Testing the Redirects

Run your Next.js application to test the redirects.

Start your Next.js application:

npm run dev
# or
yarn dev

Navigate to http://localhost:3000/old-route and http://localhost:3000/temporary-redirect to verify that they redirect to the correct new routes.

Step 5: Implementing Client-Side Redirects

Sometimes, you might need to handle redirects on the client side, for example, after form submission or authentication.

Create a new page pages/redirect-client.js:

// pages/redirect-client.js
import { useEffect } from 'react';
import { useRouter } from 'next/router';

export default function RedirectClient() {
  const router = useRouter();

  useEffect(() => {
    router.push('/new-route');
  }, [router]);

  return (
    <div>
      <p>Redirecting to new route...</p>
    </div>
  );
}

Navigate to http://localhost:3000/redirect-client to see the client-side redirect in action.

Step 6: Implementing Server-Side Redirects with getServerSideProps

If you need to perform a redirect during server-side rendering, you can use getServerSideProps.

Create a new page pages/redirect-server.js:

// pages/redirect-server.js
export async function getServerSideProps(context) {
  return {
    redirect: {
      destination: '/new-route',
      permanent: false,
    },
  };
}

export default function RedirectServer() {
  return (
    <div>
      <p>Redirecting...</p>
    </div>
  );
}

Navigate to http://localhost:3000/redirect-server to see the server-side redirect in action.

Conclusion

In this guide, we covered how to implement redirects in a Next.js application. We explored configuring redirects in next.config.js, creating client-side and server-side redirects, and tested the redirects to ensure they work correctly. Properly managing redirects helps improve user experience and maintain URL integrity across your application.
