Spring Boot 4 and JavaScript React Integration: Building Modern Web Applications with REST APIs, Frontend Frameworks, and Scalable Backend Design

This book provides a practical, structured guide to building modern web applications by combining the power of Spring Boot 4 with JavaScript-driven frontends. Rather than focusing on theory alone, it walks through real development workflows that reflect how applications are designed and deployed today.
You will begin by understanding the core architecture of Spring Boot 4, including how to structure backend services, manage dependencies, and design clean APIs. From there, the book transitions into integrating JavaScript on the frontend, showing how client-side applications communicate efficiently with backend systems.
As the chapters progress, you will explore RESTful API design, data handling, authentication strategies, and performance considerations. The book also introduces practical integration patterns between backend services and modern JavaScript frameworks, helping you build responsive, maintainable applications.
By the end of this book, you will be able to design and implement full-stack systems that are scalable, structured, and production-ready. Whether you are a backend developer expanding into frontend technologies or a full-stack developer refining your workflow, this guide offers a clear and grounded path forward.
