Preface

This book is an in-depth guide to using Spring 6 and Spring Boot 3 for web development. Spring is a powerful and widely used framework for building scalable and reliable web applications in Java. Spring Boot is a popular extension to the framework that simplifies the setup and configuration of Spring-based applications. This book will teach you how to use these technologies to build modern and robust web APIs and services.

The book covers a wide range of topics that are essential for API development, such as fundamentals of REST/GraphQL/gRPC, Spring concepts, and API specifications and implementation. Additionally, the book covers topics such as asynchronous API design, security, designing user interfaces, testing APIs, and the deployment of web services. The book provides a highly contextual real-world sample app that readers can use as a reference for building different types of APIs for real-world apps, including the persistent database layer. The approach taken in the book is to guide readers through the entire development cycle of API development, including design and specification, implementation, testing, and deployment.

By the end of this book, you will have learned how to design, develop, test, and deploy scalable and maintainable modern APIs using Spring 6 and Spring Boot 3, along with best practices to ensure the security and reliability of your applications, and practical ideas to improve your application’s functionalities.
