I'll improve the project by implementing Supabase server-side rendering. This will enhance performance and security by fetching data on the server side. Let's make the necessary changes to implement this.

Let's begin by updating the Supabase client initialization:

These changes implement server-side rendering for the Supabase integration. Here's a summary of what we've done:

1. Updated the Supabase client initialization to support both client-side and server-side rendering.
2. Modified the Home page to fetch the initial session and user role on the server-side.
3. Updated the ManageUsers page to fetch the initial list of users on the server-side.
4. Adjusted the ManageUsers component to use the initial data and perform client-side updates.
5. Updated the AuthProvider to use the new Supabase client.

These changes will improve the performance and security of your application by moving some of the data fetching to the server-side. The authentication flow should still work correctly, and the manage users functionality has been updated to work with the new setup.

To complete this implementation, you may want to:

1. Update other pages (like the Dashboard) to use server-side rendering where appropriate.
2. Implement proper error handling and loading states for server-side rendered pages.
3. Add more robust type checking, especially for the data fetched from Supabase.
4. Consider implementing server actions for the create and delete user functions in the ManageUsers component for better security.

Remember to test thoroughly to ensure all functionality works as expected with these new changes.

I understand the error you're encountering. It seems that the supabase export is not being recognized. Let's revise the code to address this issue.

Let's start by updating the Supabase client initialization file:

These changes should resolve the error you were encountering. Here's a summary of what we've done:

1. Updated the Supabase client initialization to export separate functions for creating browser and server clients.
2. Modified components to use the createBrowserClient() function instead of importing supabase directly.
3. Updated the server-side rendering in app/page.tsx to use the createServerClient() function.
4. Ensured that all components are using the correct Supabase client based on their context (server or client-side).

These modifications should resolve the export error and maintain the functionality of your application. Remember to test thoroughly to ensure all features are working as expected after these changes.
