Preface

In the highly interconnected world of microservices, gRPC has become an important communication technology. By standing on the shoulders of Protobuf and implementing must-have features during communication, gRPC provides reliable, efficient, and user-friendly APIs. In this book, you will explore why this is the case, how to write these APIs, and how to use them in production. The overall goal is to get you to understand how to use gRPC but also how gRPC works. First, you will get an introduction to the networking and Protobuf concepts you need to know before using gRPC. Then, you will see how to write unary and different stream APIs. And finally, in the rest of the book, you will learn about gRPC’s features and how to create production-grade APIs.
