• This hook contains critical auth logic; consider adding unit tests or integration tests to ensure correct handling of fetch errors and auth state changes.

export function useUser() {

Consider creating and reusing a single Supabase client instance outside of the effect to avoid instantiating multiple clients and improve performance.

Suggested change

const supabase = createClient();

The alt text is generic. For better accessibility, include the user’s full name in the alt (e.g., alt={${user.firstName} ${user.lastName}'s avatar}).

Merging the current user state directly can lead to stale data if updates are concurrent. Use the functional form (setUser(prev => ({ ...prev!, ...userData }))) to ensure you’re always working with the latest state.

Suggested change

	setUser({ ...user, ...userData });
	setUser(prev => ({ ...prev!, ...userData }));

Using a javascript: URL in href can be a security risk and isn’t recommended in Next.js. Consider using a button with an onClick handler (e.g., onClick={() => router.back()}) or programmatic navigation.

Suggested change

	<Link href="javascript:history.back()">
	<ArrowLeft className="mr-2 h-4 w-4" />
	Go Back
	</Link>
	<button
	onClick={() => history.back()}
	className="flex items-center gap-2"
	>
	<ArrowLeft className="mr-2 h-4 w-4" />
	Go Back
	</button>
