Overview of this book

Explore how Protocol Buffers (Protobuf) serialize structured data and provides a language-neutral, platform-neutral, and extensible solution. With this guide to mastering Protobuf, you'll build your skills to effectively serialize, transmit, and manage data across diverse platforms and languages. This book will help you enter the world of Protocol Buffers by unraveling the intricate nuances of Protobuf syntax and showing you how to define complex data structures. As you progress, you’ll learn schema evolution, ensuring seamless compatibility as your projects evolve. The book also covers advanced topics such as custom options and plugins, allowing you to tailor validation processes to your specific requirements. You’ll understand how to automate project builds using cutting-edge tools such as Buf and Bazel, streamlining your development workflow. With hands-on projects in Go and Python programming, you’ll learn how to practically apply Protobuf concepts. Later chapters will show you how to integrate data interchange capabilities across different programming languages, enabling efficient collaboration and system interoperability. By the end of this book, you’ll have a solid understanding of Protobuf internals, enabling you to discern when and how to use and redefine your approach to data serialization.

The project: address book

As mentioned in the introduction, this is a practical chapter. We are going to create a mini command-line interface (CLI) that lets us create and list contacts in an address book. Before we dive into the code, we will talk about the project itself and some of the architectural choices made in this project.

So, let’s talk about the project. This address book project was heavily influenced by the official tutorial in the Protobuf documentation (https://protobuf.dev/getting-started/gotutorial/). However, there are quite a few changes that I made to cover more Protobuf concepts. Here are the changes that I made:

  • Instead of adding only a person’s contact in the address book, we will also be able to add a company’s contact. This lets us use oneof because the contact will be either a company or a person.
  • While the CLI will not cover searching the contact by name (this is a challenge for you), we made sure that it would be possible...
