How Can I Safely Access the 'window' Object in a Next.js Application?

Accessing 'Window' in Next.js React Application

In React applications that utilize Next.js, you may encounter difficulties accessing the 'window' object. This can manifest as a 'ReferenceError: window is not defined' error.

To address this issue, a common solution is to encapsulate the code accessing the 'window' object within a conditional statement that checks for its existence. This ensures that the code only executes when running in a browser environment, where the 'window' object is present.

if (typeof window !== "undefined") {
  // Client-side-only code
}

This approach ensures that the code attempting to access the 'window' object only executes on the client side, where it is available within the browser environment.
