How do I use gRPC reflection for tooling in Go?

gRPC reflection is a powerful feature that allows tooling to discover the types and methods defined in gRPC services dynamically at runtime. This is particularly useful for debugging and client generation. Using gRPC reflection in Go is straightforward with the help of the `grpc-reflection` package provided by Google.

Using gRPC Reflection in Go

To use gRPC reflection in your Go application, you need to follow these simple steps:

Import the necessary packages.
Register the reflection service with your gRPC server.
Run your server and test the reflection using a gRPC client.

Example Code


        // Import necessary packages
        import (
            "google.golang.org/grpc"
            "google.golang.org/grpc/reflection"
            "net"
            "log"
        )

        // Define your gRPC server
        type server struct{}

        // Main function
        func main() {
            lis, err := net.Listen("tcp", ":50051")
            if err != nil {
                log.Fatalf("failed to listen: %v", err)
            }
            s := grpc.NewServer()
            
            // Register reflection service on gRPC server
            reflection.Register(s)

            log.Println("Server is running on port :50051")
            if err := s.Serve(lis); err != nil {
                log.Fatalf("failed to serve: %v", err)
            }
        }
