Description Mastering Domain-Driven Design provides a comprehensive guide to understanding and implementing DDD, an approach to software development that helps you tackle complex projects by aligning your code with the core business concepts. The book explains the process for designing and modernizing software applications, applying Domain-Driven Design methods to all design and development stages. It describes creating business models using canvases and capability maps, gathering business requirements using domain storytelling and visual glossaries, designing the macro architecture using event storming, and designing single services using tactical and API design. It also describes how to involve all development or modernization partners, such as business experts, developers, or customers, in application development in a highly collaborative and engagement-driven process. By the end of this book, you will have the knowledge and practical skills to confidently apply Domain-Driven Design principles in your own projects. Whether you are building new software or working with existing systems, this book will help you to create robust, maintainable, and business-aligned solutions. Key Features Collaborative design process including all stakeholders. Makro-design of services and the tactical design of APIs and events. Comprehensive process from the ideation to the design of interfaces. What you will learn Wardley map for prioritization of capabilities. Domain storytelling to gather business requirements. Visual glossary to define the ubiquitous language. Event storming to define bounded context and domain events. OpenAPI to define synchronous interfaces. AsyncAPI to define asynchronous interfaces. Who this book is for This book is for software developers, architects, and technical leaders who want to learn how to build robust and maintainable software systems. Readers should have a basic understanding of software development principles and object-oriented programming concepts. Table of Contents 1. Introduction to Domain-Driven Design 2.
