Angular Signals — Everything You Need To Know

Angular Signals is the new change detection revolution for the Angular framework.

And developers are lovin it.

A few folks seem to be disgruntled at the new direction. Some folks just don’t like ground-breaking changes.

But the Angular team has affirmed their commitment to backward compatibility, and ran an entire RFC on Angular Signals before releasing the new Angular signal changes. So it’s entirely up to you whether or not you embrace the new change detection system. Zone.js is still around and will be for awhile.

But why Angular signals? Why a new change detection system?

The reason for Angular signals is simple — improve change detection performance.

Signals allow the Angular framework to optimize change detection performance. Plus they’re a lightweight dependency — 2KB to be exact.

This is a really sweet deal if you’ve got a large Angular enterprise app that requires lots of client rendering.

So, today, I’m going to show you everything you need to know about Angular signals.
