golang-grpc\nGo언어와 gRPC를 사용하며, [gRPC [Golang] Master Class: Build Modern API \u0026 Microservices](https://udemy.com/course/grpc-golang/)를 보면서 Go언어에서 gRPC를 사용하는 방법을 익힙니다.\n\n## Installation\n\n### gRPC\n```shell\nexport GOPATH=$HOME/go\nexport PATH=$PATH:$GOPATH/bin \n```\n\n```shell\n$ brew install protoc-gen-go\n$ brew tap yoheimuta/protolint\n$ brew install protolint\n$ go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest\n$ go install google.golang.org/protobuf/cmd/protoc-gen-go@latest\n```\n\n## Generate gRPC\n```shell\n$ protoc -Igreet/proto --go_out=. --go_opt=module=github.com/dev-hyunsang/grpc-go-course --go-grpc_out=. --go-grpc_opt=module=github.com/dev-hyunsang/grpc-go-course greet/proto/dummy.proto\n```\n\n## Using Evans\n###
