Fixing the WaveSurfer.create is not a function Error in Next.js

Integrating third-party libraries into your applications can sometimes lead to frustrating errors. If you are working with Next.js and trying to use WaveSurfer.js, you might encounter the error: WaveSurfer.create is not a function. This can be particularly challenging if you are unsure how to correctly import and utilize the library. In this post, we'll break down the problem and provide a clear solution to get you back on track.

Understanding the Issue

When you see the error message WaveSurfer.create is not a function, it indicates that the WaveSurfer object has not been imported correctly, or that the method you're trying to use isn't defined on the object as expected. This often occurs in a server-rendered environment like Next.js, where components may need special handling to avoid executing code on the server that is meant to run only in the browser.

The Solution: Importing a Component Instead

Instead of dynamically importing WaveSurfer.js directly, you should import a component that utilizes the library. This change allows the proper initialization of the WaveSurfer instance and avoids the existing error. Here’s how to do it step by step.

Step 1: Create the Component

Firstly, you need to create your own component that will use WaveSurfer.js. Here’s how a simple component might look:

This component creates a new WaveSurfer instance when it mounts and cleans up when it unmounts.

Step 2: Use Dynamic Import for the Component

Next, you need to dynamically import this component within your Next.js application. Here’s how you can do that:

Step 3: Render the Component

Now, you can render DynamicComponent wherever you like in your layout, and it will utilize the WaveSurfer library without any issues. By importing the component instead of the library directly, you ensure that all the necessary functions and methods are properly available in the context of your application.

Conclusion

By following these steps, you can resolve the WaveSurfer.create is not a function error effectively. Remember that in Next.js, handling dynamic imports correctly is crucial, especially when dealing with libraries that may depend on the browser environment. This solution not only helps you utilize WaveSurfer.js correctly but also enhances your understanding of component management in Next.js.
