FAQs about being a GraphQL Developer
What is GraphQL and how does it differ from REST?
GraphQL is a query language for APIs and a runtime for executing those queries by using a type system you define for your data. Unlike REST, which exposes multiple endpoints for different resources, GraphQL exposes a single endpoint and allows clients to request exactly the data they need, reducing over-fetching and under-fetching of data.
How do you handle authentication and authorization in a GraphQL API?
Authentication and authorization in GraphQL are typically handled at the resolver level or through middleware. You can use context to pass user information to resolvers and implement logic to check user permissions before resolving data, ensuring secure access to resources.
What are some common performance optimization techniques in GraphQL?
Common performance optimizations in GraphQL include query batching, caching, using dataloaders to prevent N+1 query problems, and limiting query depth and complexity. These techniques help improve response times and reduce server load.
