Go Programming Blueprints - Second Edition

Summary

We covered a lot through this chapter as we put together a real example of a micro-service. There is a lot of work involved without code generation, but the benefits for large teams and big micro-service architectures pay for the investment as you build self-similar, discrete components that make up the system.

We learned how gRPC and protocol buffers give us highly efficient transport communications between clients and servers. Using the proto3 language, we defined our service, including messages, and used the tools to generate a Go package that provided the client and server code for us.

We explored the fundamentals of Go kit and how we can use endpoints to describe the methods of our services. We let Go kit do the heavy lifting for us ...
