Summary

gRPC is fast, easy to use and understand, and exchanges data in binary format. This chapter taught you how to define the methods and the messages of a gRPC service, how to translate them into Go code, and how to develop a server and a client for that gRPC service.

So, should you use gRPC or stick with RESTful services? Only you can answer that question. You should go with what feels more natural to you. However, if you are still in doubt and cannot decide, begin by developing a RESTful service and then implement the same service using gRPC. After that, you should be ready to choose.

The last chapter of the book is about generics, which is a Go feature that is currently under development and is going to be officially included in Go in 2022. However, nothing prohibits us from discussing generics and showing some Go code to better understand generics.
