--- title: Handling "Dynamic href is not Supported in the App Router" Error in Next.js description: This document describes the dynamic href is not supported in the App Router error in Next.js and provides a solution to fix it. --- ## Why This Error Occurred The "Dynamic `href` is not supported in the App Router" error happens when you try to use a dynamic `href` with `next/link` in the `app` directory. The new client-side router in Next.js does not use a mapping of dynamic routes to URLs, but rather it leverages the URL directly. This means it doesn't support dynamic `href` use. ## Possible Ways to Fix It You need to replace the dynamic `href` with a direct path in the `next/link` component. Here's a before and after comparison of what your code should look like: **Before** ```jsx link ``` Or ```jsx link ``` **After** ```jsx link ``` In the revised code, the dynamic part of the `href` (`[slug]`) is replaced directly with the actual value (`1`), which simplifies the `href` and makes it a direct path. ## Useful Links - [`next/link` documentation](/docs/app/api-reference/components/link#href-required) - Learn more about the usage of `next/link` in Next.js.
