In this guide, we'll dive into a specific TypeError that occurs when using the cookieCutter library, and how you can efficiently resolve this issue without unnecessary imports.

The Problem: Understanding the TypeError

The error that many developers face is as follows:

Explanation of the Error

In your code, you are correctly importing cookieCutter, but when you invoke it inside the GetData function, which runs on the server side, it fails to retrieve cookie data and returns a TypeError instead.

The Solution: Moving Logic to useEffect

To address this issue, the best course of action is to utilize the React Hook useEffect. This hook allows you to run specific code only after the component has mounted in the browser, ensuring that your cookie access logic is executed client-side.

Step-by-Step Guide to Implement the Solution

Create a Custom Hook:
Define a custom hook that encapsulates the logic for fetching user data once the component is mounted.

Use useEffect:

Modify Your Code:
Update your User module to incorporate useEffect. Here’s how you can structure it:

4. Integrate the Custom Hook:

In your dashboard component, simply call this custom hook. You won’t need to worry about importing cookie fetching logic directly into your components anymore.

Conclusion: Cleaning Up Your Code

By moving cookie-fetching logic to a useEffect inside a custom hook, you not only prevent the TypeError but also maintain cleaner and more readable code. This pattern allows you to separate concerns and keep your components focused on rendering UI rather than managing data fetching logic explicitly.
