gRPC and Protobuf

Protobuf

    $ go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
    $ go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest

• Update your PATH so that the protoc compiler can find the plugins:

    $ export PATH="$PATH:~/go/bin"

protoc --go_out=../service --go_opt=paths=source_relative --go-grpc_out=../service --go-grpc_opt=paths=source_relative UserRequest.proto
