Reactivity with Signals in Angular v19+

Angular Signal Crash Course

Description

Angular Signals are the future of reactivity in Angular, offering a lightweight, intuitive alternative to RxJS for managing component state. In this concise, code-along course, you’ll learn how to build a fully functional shopping cart using Angular Signals in under an hour

Whether you’re an Angular beginner or a seasoned dev looking to level up your state management skills, this course walks you through the core concepts of Signals:

• signal() for reactive state

• computed() for derived values

• effect() for side effects

• Using signals in templates

• Persisting state with localStorage

You’ll build a clean, reactive shopping cart that tracks item quantity, calculates totals in real-time, and saves to the browser. Along the way, you’ll see how Signals make Angular apps simpler, faster, and easier to reason about. No RxJS required.

By the end, you’ll not only understand Signals conceptually, but also know how to use them confidently in real-world projects.
