How to Perform Absolute Redirects with useRouter in Next.js 14

In modern web development, routing is a fundamental aspect that can significantly affect user experience. When working with Next.js, a popular React framework for server-side rendering, developers often encounter challenges with routing, particularly when trying to navigate between different pages.

The Problem: Routing Logic in Next.js

A common issue arises when using the useRouter hook for redirection. For instance, if you are on the path auth/login/approve and try to push a new route like auth/new-password, you might expect the user to be directed straight to auth/new-password. However, the router interprets this relative URL in a way that results in an undesired path like auth/login/auth/new-password.

Why is This Happening?

The problem lies in how the useRouter reacts to relative paths. When navigating using router.push(), if you don't specify the leading forward slash /, Next.js treats the provided path as relative to the current path. Thus, including that slash is crucial for defining absolute routes.

The Solution: Correcting the Route

To redirect correctly, you must ensure you're using absolute paths when passing them to router.push(). Here's how to do this properly:

Step-by-Step Implementation

Import the useRouter Hook:
Ensure you're importing the useRouter from the next/navigation:

Alternative Using Redirect

Besides using router.push(), you can also leverage the redirect method from the next/navigation package for smaller or more direct use cases:

Summary

Redirecting users in Next.js using the useRouter hook can sometimes lead to unexpected behavior if relative paths are not handled correctly. Always use absolute paths (with a leading forward slash) to ensure that your app routes users accurately.

By following the steps outlined above, you can effectively navigate users in your Next.js application, improving their experience and the overall usability of your web application. Happy coding!
