Prerequisites

Before we get to coding, ensure that you have installed the gRPC API Gateway protobuf plug-in. Refer to Installation section for related instructions.

gRPC API Gateway is a protoc plug-in, similar to the Go code generator and the tool relies on the generated code from both Go and Go gRPC plug-ins.

In order to install Go and Go gRPC plug-ins, execute the following commands:

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