To design a scalable GraphQL API with Apollo Server, define a type-safe schema, implement resolvers for data fetching, and apply best practices like cursor-based pagination and DataLoader to prevent N+1 query problems.

The best way to prevent N+1 query problems in GraphQL is to use DataLoader for batching and caching data fetching requests, combined with cursor-based pagination for efficient data retrieval across large datasets.

You implement GraphQL subscriptions and mutations by defining the respective operations in your type-safe schema definition, creating input validation rules, and writing resolvers that handle data creation and real-time event notifications.

Yes, this GraphQL API design approach supports input validation and error handling by providing example resolver implementations that include authentication, data fetching safeguards, and effective error management practices.

Yes, you can use Prisma with Apollo Server for GraphQL backend development to streamline database access, ensure type safety, and generate efficient resolvers for queries, mutations, and subscriptions.

You need cursor-based pagination in a GraphQL API when retrieving large datasets efficiently, preventing performance bottlenecks and ensuring scalable data fetching without overwhelming the database or client.
