GraphQL data fetching in React using Apollo Client is implemented via the useQuery hook, which manages loading, error, and data states. You execute a query by passing your GraphQL document to useQuery to retrieve data efficiently.

The best way to handle GraphQL mutations in React is using the useMutation hook. You can implement optimistic updates and manually update the Apollo Client cache after a mutation to ensure your UI reflects changes immediately.

Cursor-based pagination with Apollo Client works by using the fetchMore function combined with cache merge functions. This approach updates your query variables and merges new paginated results into the existing local cache seamlessly.

Yes, you can configure custom Apollo Links for authentication and error handling during Apollo Client setup. Custom links intercept outgoing requests to inject tokens, handle tracing, and manage errors before they reach your UI components.

Common pitfalls with Apollo Client for state management include improper cache invalidation and failing to handle loading or error states. Following production-ready patterns for queries, mutations, and custom links helps avoid these issues.
