Angular Signals — A Practical Guide

What signals are, when to use them, and how they compare to RxJS in modern Angular.

Signals changed how state works in Angular. This guide explains them clearly and practically.

This guide covers Angular signals in practical terms — signal, computed, and effect, signal inputs and outputs, when signals fit better than RxJS, common pitfalls (effect loops, over-using effects), and interop with observables via toSignal and toObservable.
