Explore vertical slice architecture in this comprehensive conference talk by Jimmy Bogard. Learn how to transition from layered architecture, focusing on building along the axis of change. Discover new structures, patterns, and policies for this architectural style, addressing common business functionality and integrating concepts like CQRS and DDD. Dive into patterns, tools, and techniques used with slices, and understand their application in desktop, SPA, and MVC applications. Examine challenges associated with slices and layers, and uncover how this approach leads to more maintainable systems. Gain insights into organizing code, modeling requests and responses, handling commands and queries, and implementing encapsulation. Explore topics such as SQL projections, domain validation, pipeline behaviors, and testing strategies for both queries and commands.
