War of the APIs - REST vs GraphQL vs gRPC by Memi Lavi

Compare the strengths and weaknesses of REST, GraphQL, and gRPC APIs, exploring their suitability for complex queries, scalability, performance, and real-time data streams.

Key takeaways
  • REST API is the most popular API, but it’s not suitable for complex queries and has performance issues.
  • GraphQL is schema-based, flexible, and scalable, making it suitable for complex queries and large datasets.
  • gRPC is a binary-based protocol that provides high-performance and low-latency communication, making it suitable for real-time data streams.
  • REST API is not entity-oriented, while GraphQL and gRPC are.
  • GraphQL provides schema-based reasoning, making it easier to reason about the data.
  • gRPC provides multiple communication styles, including unary, client-streaming, and server-streaming.
  • GraphQL provides a subscription-based API, making it suitable for real-time data streams.
  • REST API is not designed for real-time data streams, while GraphQL and gRPC are.
  • GraphQL and gRPC provide better performance and scalability than REST API.
  • REST API is easier to implement, but GraphQL and gRPC require more effort to set up.
  • GraphQL and gRPC provide more flexibility in querying data, while REST API is more rigid.
