Kapoor S. Practical Angular Signals. Levelling Up Your Web Development...2025

Textbook in PDF format This succinct, advanced-level guide to Angular Signals is built around a real-life shopping cart application designed for experienced Angular developers who want to level up their skills and see how to implement Signals in complex, production-grade applications. Through the creation of a shopping cart app, you will explore how to model application state with Signals, manage side effects, and integrate Signals into key Angular features such as HTTP APIs, routing, guards, directives, and more. The book begins with establishing the application structure for scalability and then moves on to modelling product and cart state with Signals. This is followed by a chapter on Effects, APIs, and Async Data with Signals. The book then moves on to discussing component communication and Routing, Guards and Auth. The penultimate chapter deals with performance, testing and debugging of the shopping cart application that you will have learnt how to create. The final chapter involves patterns for migrating from RxJS or NGRX to Signals. Angular took a bold step in reinventing itself with the addition of Signals to the API surface. The intentions were not to bloat the API with tools that don’t serve developers but instead to provide developers with the critical infrastructure required to build scalable web applications that serve their users. We wanted to place developers in a winning position – one where they could create applications their users will love. We’ve done that with the introduction of Signals to the Angular community. As we continue to mature and expand the API surface, developers will need real-world insights that empower them to build great applications. Sonu’s book does just that. Anyone can go to the documentation for a new API and learn the fundamentals, but often that isn’t enough. Developers need to go beyond the basics into real-world, tested patterns and structure. This book is a great resource for any developer looking to do just that. This book doesn’t try to cover the entire scope of Angular but, instead, sharply focuses on Signals – much to the developer’s benefit. The book is a must-have if you are seeking to move beyond tutorials and into real-life implementation of Signals in scalable commercial applications
