Resolving the async/await Error in Next.js 13 Client Components

If you’re working with Next.js 13 and have encountered the error message that states: “Error: async/await is not yet supported in Client Components, only Server Components,” you’re not alone. This issue can be frustrating, especially when you think your code is correctly structured. In this guide, we will explore what this error means and how to effectively solve it.

Understanding the Problem

The error you are facing typically arises when attempting to perform asynchronous operations in a component classified as a Client Component. In your case, it's linked to your DataManufactureNav function, which is defined as an async function. Since async/await is not permitted in Client Components in Next.js, trying to import any Server Component within a Client Component will lead to this error.

Key Takeaways:

Client Components cannot handle async/await functions.

Server Components are designed for performing asynchronous actions, such as fetching data.

The Solution: Separate Your Components Appropriately

To resolve this issue, we need to ensure that our components are utilized in a way that respects the boundaries set by Next.js for Client and Server Components. There are a few strategies you can employ to achieve this.

1. Convert Client Component to a Server Component

The simplest solution might be to convert your Navbar component into a Server Component by removing the "use client" directive at the top. This will allow you to retain your use of async/await in DataManufactureNav. Here's a restructured example:

2. Refactor Asynchronous Code

If you prefer to keep Navbar as a Client Component, you need to refactor the data fetching out of DataManufactureNav and make it synchronous. You can do this by fetching data in a useEffect hook or server-side logic before passing data to your components through props.

Example of Refactoring Using useEffect

3. Use Static or Server Rendering

If the intention is to ensure the navbar updates with the latest data without needing client-side interactions, consider using Static Generation (SSG) or Server-Side Rendering (SSR). This will allow for dynamic data fetching at build time or request time, respectively, without running into async issues.

Conclusion

By structuring your components according to the rules of Next.js regarding Client and Server Components, you can overcome the async/await error mentioned earlier. Whether you choose to convert the component, refactor the code, or use static/server rendering, ensure that asynchronous logic resides in Server Components to maintain a clean and efficient codebase.
