Description

Master Angular Signals: Modern Change Detection and Zoneless ApplicationsUnlock the full potential of Angular's newest feature-Signals. This course begins by explaining the motivation behind signals, diving into the fundamentals of the event loop, tasks, and how zone-based change detection works. You'll discover why Angular is shifting towards zoneless architectures and the challenges posed by using RxJS and push-based change detection in large-scale applications.We then introduce the basic primitives of signals, including their relationship to injection and reactive contexts. You'll learn how to work with writable and computed signals, and how to implement effects and handle RxJS interoperability. These foundational concepts will help you start using signals effectively in your applications.Once the basics are covered, we dive deep into how signals are implemented under the hood to give you a more advanced, intuitive understanding of their behavior. This deep understanding of how signals and injection contexts work will help you avoid the pitfalls of this seemingly simple feature, enabling you to use signals effectively and confidently.Angular 18's new signal-based component API is a game-changer for modern Angular development. In this course, you'll learn how to integrate signals directly into your components, significantly improving performance and reducing complexity. We'll explore how the deep understanding of signals and injection contexts is essential to mastering these APIs and avoiding common mistakes. With this knowledge, you'll be able to build more efficient, responsive, and scalable components that take full advantage of Angular's latest features.Moving beyond components, we dive into building signal-based services, which offer a powerful, scalable solution for real-world Angular applications. The course concludes with a comprehensive hands-on practical example, allowing you to apply everything you've learned throughout the course.Whether you're a beginner looking to understand signals or a seasoned Angular developer seeking to deepen your expertise, this course provides both theoretical insights and practical knowledge. By gaining a deep understanding of how signals work, you'll gain the confidence to build efficient, scalable, and future-proof applications while avoiding common pitfalls.
