To set up Apollo Client in a React application, install @apollo/client, create an ApolloClient instance with InMemoryCache and HttpLink, and wrap your app with ApolloProvider to enable GraphQL data management.

You can manage local state in Apollo Client by using reactive variables. This approach allows you to handle local data alongside your GraphQL queries and mutations without requiring additional state management libraries.

Yes, Apollo Client 4.x works with Next.js, Vite, and Create React App. You can configure cache policies, type policies, and data masking to optimize GraphQL performance across these typical React frameworks.

The best way to configure GraphQL caching in React is by using Apollo Client's InMemoryCache. You define type policies and data masking rules to optimize performance and control how your application fetches and stores data.

Installing rxjs is required for Apollo Client to handle asynchronous operations and reactive data streams. You need it alongside @apollo/client and graphql to properly manage GraphQL query and mutation execution.

You perform GraphQL queries and mutations using React hooks provided by Apollo Client. After wrapping your application with ApolloProvider, you can use these hooks to fetch data and execute operations directly within your components.
