gRPC Go for Professionals

Overview of this book

In recent years, the popularity of microservice architecture has surged, bringing forth a new set of requirements. Among these, efficient communication between the different services takes center stage, and that's where gRPC shines. This book will take you through creating gRPC servers and clients in an efficient, secure, and scalable way. However, communication is just one aspect of microservices, so this book goes beyond that to show you how to deploy your application on Kubernetes and configure other tools that are needed for making your application more resilient. With these tools at your disposal, you’ll be ready to get started with using gRPC in a microservice architecture. In gRPC Go for Professionals, you'll explore core concepts such as message transmission and the role of Protobuf in serialization and deserialization. Through a step-by-step implementation of a TODO list API, you’ll see the different features of gRPC in action. You’ll then learn different approaches for testing your services and debugging your API endpoints. Finally, you’ll get to grips with deploying the application services via Docker images and Kubernetes.

Prerequisites

You can find the code for this chapter at https://github.com/PacktPublishing/gRPC-Go-for-Professionals/tree/main/chapter2. In this chapter, we are going to discuss how Protocol Buffers serializes and deserializes data. While this can be done by writing code, we are going to stay away from that in order to learn how to use the protoc compiler to debug and optimize our Protobuf schemas. Thus, if you want to reproduce the examples specified, you will need to download the protoc compiler from the Protobuf GitHub Releases page (https://github.com/protocolbuffers/protobuf/releases). The easiest way to get started is to download the binary releases. These releases are named with this convention: protoc-${VERSION}-${OS}-{ARCHITECTURE}. Uncompress the zip file and follow the readme.txt instructions (note: we do intend to use Well-Known Types in the future so make sure you also install the includes). After that, you should be able to run the following command:

$ protoc --version

Finally, as always, you will be able to find the companion code in the GitHub repository under the folder for the current chapter (chapter2).
