If you not familiar with gRPC you may want to read Introduction to gRPC first.

• Go, we were using version 1.15.x when this document was created. For installation instructions, see Go’s Getting Started Guide
• Protocol buffer compiler, protoc, version 3. For installation instructions, see Protocol Buffer Compiler Installation
• Go plugin for the protocol compiler:

Install the protocol compiler plugin for Go (protoc-gen-go) using the following command:

export GO111MODULE=on # Enable module mode
go get github.com/golang/protobuf/protoc-gen-go

Update your PATH so that the protoc compiler can find the plugin:

export PATH="$PATH:$(go env GOPATH)/bin"

protoc --go_out=plugins=grpc:../. protobuf/helloworld.proto

generate grpc-gateway

protoc --grpc-gateway_out ../. protobuf/helloworld.proto

generate swagger config

protoc --swagger_out . protobuf/helloworld.proto

or generate everything at once

protoc --go_out=plugins=grpc:../. --grpc-gateway_out ../. --swagger_out . protobuf/helloworld.proto

go run server/main.go

go run rest/main.go

go run client/main.go [name]
