Modern Angular 19 with Signals - The missing guide

Modern Angular 19 with Signals - The missing guide

Learn how to code in Angular 19 using the new feature: "Signals", Use the new best practices while avoiding the pitfalls

Master Angular Signals: Modern Change Detection and Zoneless Applications

Unlock the full potential of Angular's newest feature—Signals. Learn the modern way to prgram in Angular using  Signals, Standalone Architecture, the new functional APis, and all the latest features, including the ones introduced in Version 19.

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.

What you'll learn

• How to develop in Angular using Signals?
• How to avoid the pitfalls of the signals feature?
• The new functional signal based APIs of angular
• See the new Standalone architecture in action
• What are the newest best practices?
• How Change detection works and what is a zoneless application?
• How to use the newest features to simplify your application structure
• Learn the newest signal related APIs of Angular 19

First - understand why angular is moving to zoneless applications using signals. Dive 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.

Then - meet signals. Learn about 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. 

You'll also discover Angular 19s "linkedSignal". 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 19’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. The course concludes with a comprehensive hands-on practical example, allowing you to apply everything you've learned throughout the course. 

We also cover the apis released in version 19: resource and rxResource. You will see how to incorporate them into your reactive services.
