Resolvers are critical for a robust GraphQL server, handling logic to return appropriate data for each schema field. Key concepts include resolver maps, chains, mappers, and defer resolve, which help optimize database queries and minimize redundant operations. Effective resolver implementation can be improved using tools like GraphQL Code Generator and Server Preset to ensure type safety and reduce runtime errors.
