Modern API Development with Spring and Spring Boot

By: Sourabh Sharma

Overview of this book

The philosophy of API development has evolved over the years to serve the modern needs of enterprise architecture, and developers need to know how to adapt to these modern API design principles. Apps are now developed with APIs that enable ease of integration for the cloud environment and distributed systems. With this Spring book, you'll discover various kinds of production-ready API implementation using REST APIs and explore async using the reactive paradigm, gRPC, and GraphQL. You'll learn how to design evolving REST-based APIs supported by HATEOAS and ETAGs and develop reactive, async, non-blocking APIs. After that, you'll see how to secure REST APIs using Spring Security and find out how the APIs that you develop are consumed by the app's UI. The book then takes you through the process of testing, deploying, logging, and monitoring your APIs. You'll also explore API development using gRPC and GraphQL and design modern scalable architecture with microservices. The book helps you gain practical knowledge of modern API implementation using a sample e-commerce app. By the end of this Spring book, you'll be able to develop, test, and deploy highly scalable, maintainable, and developer-friendly APIs to help your customers to transform their business.

Chapter 11: gRPC-based API Development and Testing

You will learn how to implement gRPC-based APIs in this chapter. You will learn how to write the gRPC server and client along with writing the APIs based on gRPC. In the later part of this chapter, you will be introduced to microservices and will see how they will help you to design modern scalable architecture. Here, you will go through the implementation of two services – the gRPC server and the gRPC client. gRPC-based APIs are more popular and preferred for inter-service communication in a microservice-based system. Hence, gRPC development skills are an important topic in the API space.

You will explore the following topics in this chapter:

  • Writing an API interface
  • Developing the gRPC server
  • Handling errors
  • Developing the gRPC client
  • Learning microservice concepts

After completing this chapter, you will have the following skillset – gRPC server and client development, gRPC-based API...
