Book Description

REST is the backbone of modern web services and APIs, powering most internet applications today. However, many developers struggle with poorly designed endpoints, inadequate error handling, security vulnerabilities, and others. Addressing these issues requires a deep understanding of REST architecture, the HTTP protocol, and related concepts, which this book provides. Starting with the fundamentals of REST architecture and HTTP protocols, this book introduces key concepts inspired by Roy Fielding’s principles and the Richardson Maturity Model. You'll begin by building a Product API, progressively enhancing it with documentation, versioning, and security features. As you advance, you'll also create an Order Management API designed to interact with the Product API, applying techniques for testing and optimizing performance. Each chapter offers step-by-step explanations and practical examples, guiding you through the process of developing and refining robust, scalable APIs while enhancing your overall development skills. By the end of this book, readers will be able to confidently build RESTful APIs using Java, ensuring their readiness for the dynamic challenges of modern application development.
