#gRPC

Why REST still dominates, what GraphQL actually solves, and when gRPC really shines. A practical breakdown of all three API protocols with real code and decision criteria.

JSON is heavy, and REST is chatty. Enter gRPC, Google's answer to high-performance microservices communication. We explore the magic of Protocol Buffers serialization, the power of HTTP/2 multiplexing, and the four streaming patterns. We also cover the caveats: why gRPC is hard to use in browsers and how load balancing differs from HTTP/1.1.
