The Problem

Example Code Snippet

Consider the following code that illustrates the issue:

In the above snippet, the API is expected to fetch a user based on the provided username. However, without a proper setup, this can lead to unexpected results.

The Solution

Step 1: Create a Dynamic API Route

You will need to create a new API route that utilizes the username directly from the URL rather than the request body. This can be accomplished by creating a file under pages/api/profilepages with the name [username].js. Your folder structure should look like this:

Step 2: Modify the Fetch Request in Your Component

Next, you will need to modify the fetching logic in your component. Instead of posting the username, you will pass it in the URL when calling the API. This is how to update your useSWR setup:

Benefits of Using Dynamic Routes

Flexibility: You can easily change the username in the URL without modifying your backend logic.

Cleaner Code: No need to handle request bodies, which simplifies the API route code.

Improved Structure: Making API routes more RESTful by matching endpoint patterns to data being accessed.
