How to redirect to an external URL in Next.js

In this tutorial, we are going to learn about how to redirect a user to an external URL in Next.js.

Redirects allow you to redirect an incoming request from the user (/about) to a different destination (https://google.com/about/).

Redirecting to an external URL

We can redirect to an external URL in Next.js by adding the following config to our next.config.js file.

Here is an example:

next.config.js
module.exports = {

  async redirects() {
    return [
      {
        source: '/about',
        destination: 'https://google.com/about',
        permanent: false
      }
    ];
  }
};

In the example above, if any user visits the /about page in our next.js app we are redirecting them to an external URL https://google.com/about.

We can add more redirects to the redirects() async function like this.

module.exports = {

  async redirects() {
    return [
      {
        source: '/about',
        destination: 'https://google.com/about',
        permanent: true
      },
      {
        source: '/contact',
        destination: 'https://twitter.com',
        permanent: true
      }
    ];
  }
};

Note: To use redirects(), your next.js version should 9.5.0 or above.

Similarly, we can also redirect to an external URL using the window.location.href property inside the useEffect() hook.

Example:

About.js
import React, { Component, useEffect } from "react";

function About() {
  useEffect(() => {
    window.location.href = "https://google.com/about";
  }, []);

  return (
    <div>
      <h1>This page is not available</h1>
      <p>You are redirecting to google.com/about</p>
    </div>
  );
}

export default About;
