GraphQL and gRPC
Explore alternative API styles like GraphQL for flexible data fetching and gRPC for high-performance communication.
Beyond REST: GraphQL & gRPC
RESTful APIs are widely used, but they aren't always the perfect fit for every scenario.
Sometimes, you need more control over data fetching or require extremely high performance for inter-service communication.
This lesson explores two powerful alternatives: GraphQL and gRPC.
REST's Data Fetching Hurdles
Traditional REST APIs often lead to two common issues:
- Over-fetching: Receiving more data than needed in a single request, wasting bandwidth.
- Under-fetching: Needing to make multiple requests to different endpoints to gather all required data.
This can be inefficient, especially for mobile clients or complex UIs.
