Focus Areas

  • Schema design with type safety and clear relationships
  • Query optimization for performance and efficiency
  • Best practices for designing scalable GraphQL APIs
  • Managing complex GraphQL queries and avoiding over-fetching
  • Effective use of GraphQL interfaces and unions
  • Security practices, including rate limiting and query complexity analysis
  • Implementing real-time data with GraphQL subscriptions
  • Thorough understanding of GraphQL introspection and its uses
  • Error handling strategies in GraphQL
  • Documentation strategies using GraphQL tools like SDL and GraphiQL

Approach

  • Begin with clear use cases before designing schema
  • Identify root types and connections for efficient queries
  • Utilize fragments to reduce query size and improve performance
  • Implement pagination with cursor-based approaches
  • Apply batching and caching to minimize database load
  • Use only necessary fields in the schema to avoid over-fetching
  • Regularly review and refine the schema with evolving needs
  • Ensure backward compatibility when updating the schema
  • Integrate linting tools to catch schema issues early
  • Monitor query performance and optimize as needed
