gRPC server implemented with Go

gRPC Server implementation with Golang

How gRPC works

Tools used for

• Golang Programming language
• protoc Protocol Buffer library
• grpcui UI to interact with gRPC server
• grpcurl Client to make gRPC server requests
• VSCode Golang extension
• VSCode Proto 3 extension

Protoc Plugins

• protoc-gen-go protoc-gen-go is a plugin for the Google protocol buffer compiler to generate Go code.
• protoc-gen-go-grpc This tool generates Go language bindings of services in protobuf definition files for gRPC.

Generate Go Code form proto file

protoc \
--go_out=logger \
--go_opt=paths=source_relative \
--go-grpc_out=logger \
--go-grpc_opt=paths=source_relative \
logger.proto

• Generates logger/logger_grpc.pb.go with protoc-gen-go-grpc
• Generates logger/logger.pb.go with protoc-gen-go

Starts the server

go run main.go

Starts de UI in order to send log messages to the server

grpcui \
-plaintext \
-use-reflection=false \
-proto=logger.proto \
localhost:8089

Visit localhost:8089 and send log messages to the server.

You can choose the different methods to execute

Make a request to the server to get all app logs messages

grpcurl \
-plaintext \
-use-reflection=false \
-proto=logger.proto \
-d '{"name": "app"}' \
localhost:8089 Logger.GetLogsByApp
