Grpc Protocol

• protoc - Protocol Buffer compiler
• grpcurl - Command-line gRPC client
• grpc-web - gRPC for browser clients
• buf - Modern Protocol Buffer tooling
• evans - Interactive gRPC client

Target Processes

• realtime-messaging-system.js (gRPC streaming)
• custom-protocol-design.js (gRPC-based protocols)
• layer7-load-balancer.js (gRPC routing)

Usage Examples

Service Definition

service Greeter {
  rpc SayHello (HelloRequest) returns (HelloReply);
  rpc SayHelloStream (HelloRequest) returns (stream HelloReply);
}

Testing with grpcurl

grpcurl -plaintext localhost:50051 list
grpcurl -plaintext -d '{"name": "World"}' localhost:50051 greeter.Greeter/SayHello

Reflection Debugging

grpcurl -plaintext localhost:50051 describe greeter.Greeter
