The Problem

The issue arises when trying to access the pathname in a server component to fetch specific data related to that path, such as form IDs. The developer reports experiencing inconsistencies in receiving the expected ID for form submissions. This often results in errors when the ID cannot be found, which can break the application flow and frustrate users.

Here’s a brief overview of the initial code structure:

The component attempts to fetch form data based on the pathname.

Sometimes it retrieves the ID, and other times it encounters errors leading to "form not found."

The Solution: Middleware for Path Checking

To address these issues effectively, we can introduce a middleware that captures the pathname and stores it in a cookie. This ensures that it is available for the server component to fetch data consistently. Here are the steps to implement this solution:

Step 1: Create the Middleware

Step 2: Update the Server Component

Now that the middleware is established to capture and store the pathname, you'll need to modify your server component where you are fetching the data. Here’s how you can access that pathname from the request headers:

Step 3: Fetching the Data

With the pathname correctly routed and accessible, you can now implement your existing data fetching logic with confidence that it will retrieve the ID as intended.
