Mastering Angular Signals
Mastering Angular Signals
A Practical Guide to Modern Reactivity, Performance, and Migration
About the Book
From a Google-Awarded Expert in AI & Angular, this is your definitive guide to ending state management headaches and building lightning-fast Angular applications.
If you're tired of wrestling with ExpressionChangedAfterItHasBeenCheckedError, complex RxJS chains, or slow, unpredictable apps, you've found the solution.
This book is for you if you:
- ✅ Are struggling to understand when and how to use Angular Signals effectively.
- ✅ Want to build modern, zoneless applications but don't know where to start.
- ✅ Need a clear, practical plan to migrate your existing RxJS or NgRx (RxJS based) codebase.
- ✅ Are ready to write simpler, cleaner, and dramatically more performant code.
Authored by Muhammad Ahsan Ayaz—a Google Developer Expert, multiple-award-winning author, awarded by Google (via the GDE program) for his Angular course on YouTube called "MASTER Angular in 90 Minutes with This Crash Course" with over 370,000 views, and author of ngx-device-detector (an Angular library with over 13 million installs and over 5,500 GitHub projects using it today—this guide cuts through the theory and gives you battle-tested, practical strategies.
Inside, you will MASTER:
- The Core of Signals: Go from zero to hero with signal(), computed(), and effect(). Make them your new best friends for creating elegant reactive logic.
- Cleaner Component Architecture: Ditch the boilerplate. Master the new signal-based input(), model(), and output() to make your components sleek and efficient.
- Confident Data Fetching: Effortlessly manage asynchronous operations, loading states, and errors from your APIs.
- Seamless Migration: Get a step-by-step roadmap to move away from legacy RxJS and NgRx with confidence, using tools like toSignal() and toObservable().
- Rock-Solid Testing: Learn the essential strategies to test your new signal-driven components and ensure your applications are reliable and bug-free.
- Peak Performance: Go beyond the basics to fine-tune your app, explore advanced patterns, and unlock the true speed of modern Angular.
This isn't just an introduction. It's your complete playbook for the next generation of Angular development, filled with real-world code examples you can use immediately (all available on GitHub).
The future of Angular is reactive. Don't get left behind.
