Development Patterns

Server Components vs Client Components

// Server Component (default)
export default async function CustomersPage() {
  const customers = await fetchCustomers();
  return <CustomerList customers={customers} />;
}

// Client Component (interactive)
'use client';

export function CustomerForm() {
  const [name, setName] = useState('');
  // ...
}

State Management

• Apollo Client: Server state (GraphQL data)
• React Context: Global UI state
• useState/useReducer: Local component state

Local Development
